As reported by gongkong.ofweek.com, Miao Wei, the minister of MIIT
recently said that MIIT is considering intelligent manufacturing
development strategy and preparing intelligent manufacturing specialized
plan to promote the intelligentization transformation of traditional
equipment and launch intelligent workshop and intelligent plant pilot
projects on the important industries. In the same time, MIIT will
promote the development of industrial internet.
Some media
believed that industrial internet is the combination fruit of global
industrial system, advanced computing, analyzing, sensing technology and
internet. It connects man and machine and stimulates productivity
through software and big data analytics. Different from traditional
internet companies like Google and Amazon who collect data by PC and
mobile terminal backstage, industrial internet is on the base of IoT and
industrial data analysis and collects data from sensors installed on running machines; the data can be transmitted in cloud storage in real time.
Compared
to ordinary sensor, industrial sensor need better stability and
sensibility since most of them are applied in severe environment, such
as noisy production workshop and electric power monitoring. MEMS sensor
features small size, light weight, low cost, low power dissipation, high
reliability, easy access to mass production, which is a perfect choice
for industrial internet development.

Edward Brown's research is a mixture of photonics, microscopes and a little nudge from his mom.
Brown, who teaches biomedical engineering at the University of Rochester Medical Center, has built a laser-and-microscope device to study how likely cancer cells will spread throughout the body. Specifically, he's looking at how likely cancer cells have spread inside breast cancer patients who already have had the tumor removed.
Learning more about the cell movement, called metastasis, is key to a larger overtreatment problem that Brown is trying to fix.
When patients first realize they have breast cancer, it's unclear whether the cancer cells have spread, so doctors recommend chemotherapy as a precaution. However, Brown and other medical researchers believe patients are being overtreated because doctors are giving chemo to patients who may not need it.
"It's impossible to tell for sure whether that patient is going to get metastasis, so they're more likely to overtreat and give them chemo to avoid possible metastasis," Brown said.
If possible, breast cancer patients should avoid chemo, Brown said, because the procedure is "just poisons that go throughout the body that hopefully kill the tumor cells a little faster than they kill you."
Brown's device sits on a platform slightly longer than a ping-pong table. He turns on the laser and it emits a red light beam that bounces off six mirrors, then goes through four other devices that adjust the light beam's intensity and finally ends up inside the microscope. Using the device, Brown and his two graduate students are looking deep inside tumor tissue.
When Brown looks inside the microscope, he's looking at proteins and fibers immediately outside a collection of cancer cells — "the scaffolding that the cells live on." Brown believes there's a connection between how the scaffolding is made and the likelihood that cells will move. Brown can see these cells because he's using red light, which is a lower-powered light than the white light used in most microscopes.
Other researchers across the country are looking at cancer cell movement. Brown plans to publish his findings so other researchers can use them.
Brown said his research is less than five years away from being used by practicing doctors, but ultimately, if successful, his findings would allow doctors to "do patient-tailored therapy."
"We can help suggest to the patients who are more likely to experience metastasis that you should probably go into the chemo arm," he said. "Patients who are less likely to experience metastasis, you might not need the chemo."
Although he's unique by focusing on breast cancer, Brown is one of many researchers trying to find the latest breakthrough in photonics for medical purposes.
Dennis Matthews, a recently retired neurological surgery professor at the University of California, Davis, is an expert on optically based biosensors and medical devices. Matthews said photonics is still a young area of study, and the intersection of photonics and medicine is one of the major areas that researchers are studying. He mentioned an online community called Photonics 4 Life, where thought leaders share results.
There's a push nationally, Matthews said, because there are dozens of diseases that doctors can't spot early enough. Medical devices that use photonics might be able to help.
Another problem in medicine that photonics might be able to help: being able to see how the diseases react to drug treatment inside the body in real time, Matthews said.
With cancer specifically, Matthews said the goal would be to "use light to identify in a living person the presence of a (cancer) tumor."
"And if we can diagnose skin cancer earlier, that'd be great," he added.
Monroe County has some of the highest number of breast cancer cases in New York state, according to data from the state health department. Between 2008 and 2012, there was a reported annual average of 646 female breast cancer cases in Monroe County.Nearby Ontario County had an annual average 91 cases between 2008 and 2012.
There were more than 125 reported deaths caused by female breast cancer in Monroe and Ontario counties during that same time period. The department does not keep similar data for Monroe County men.
Brown is doing research on a disease that mostly affects women, so it's fitting that a woman steered him toward this field.
In 2004, his mother found an advertisement on a bulletin board from the U.S. Department of Defense asking for scientists who wanted money to research overtreatment of breast cancer patients. The $2.4 million grant would fund someone's research for the next five years and ultimately steer their career into breast cancer expertise. At his mother's urging, Brown gathered his materials, sent them in and waited.
"I remember submitting it and thinking 'I don't care if it's just for a dollar as long as I get it so I can tell my mom that I got it,'" Brown said. "So I did and I got it."

【gas transmitter,gas sensor,gas sensor suppliers, humidity sensors suppliers, infrared sensors suppliers,humidity sensors manufacturers】Textile pressure sensors can be washed|en.ofweek.com
Flexible mechanical sensors that can be bonded or sewn into woven or knitted fabrics have been developed by German research lab Fraunhofer ISC.
Deformation, force and pressure can be measured, and strains up to 100% (doubling length) can be endured.
It is an elastomer film with flexible electrodes on both sides. Electrode patterning can be used to create an array of sensors. Silicone rubber is the preferred elastomer, with chemical cross-linking allowing hardness to be tuned.
"The textile-integrated sensors are washable, show a high wearing comfort and are reasonable in price," said the lab. "They are applicable in medical devices, for preventing bed sores or for localising the pressure distribution in shoes, for example. They can also support personal training by measuring the posture via the clothes, or as an input device for game and fitness device controlling."
In a technology demonstration aimed at diabetics (see photo), 40 capacitive dielectric elastomer sensors have been attached to the sole, heel, and ankle of a sock to measure 3D compression distribution around a foot.
An asic collects measurement data from the sensors and transmits it wirelessly to a phone or tablet, for example to tell a patient to change position or weight distribution.
Fraunhofer ISC is the Institute for Silicate Research in Würzburg, which focuses mainly on energy, environment and health. It will be showing its technology at the IDTechEX in Santa Clara.

【gas sensor,gas sensor suppliers, humidity sensors suppliers, infrared sensors suppliers,humidity sensors manufacturers】Tunable mid-infrared graphene sensor detects nanoscale molecules|en.ofweek.com
Researchers at the Swiss University EPFL (école Polytechnique
Fédérale de Lausanne) and the Institute of Photonic Sciences in
Barcelona have developed a device which harnesses graphene’s novel
optical and electronic properties to develop a reconfigurable highly
sensitive molecule sensor.
The
device is claimed to have advantages compared with infrared absorption
spectroscopy, the most commonly used molecule detection method.
The European researchers claim to have harnessed the optical and electronic properties of graphene to create a tunable sensor capable of detecting nanoscale molecules such as proteins and drugs.
The
researchers used graphene to improve on a well-known molecule-detection
method: infrared absorption spectroscopy, which has important
limitations when applied to molecules at the nano-scale. The wavelength
of the infrared photon directed at a molecule is around 6 microns (6000
nm), while the target measures only a few nanometres, making it
challenging to detect the vibration of such a small molecule.
If
given the correct geometry, graphene is capable of focusing light on a
precise spot on its surface and 'hearing' the vibration of a nanometric
molecule that is attached to it. In the study , researchers first
pattern nanostructures on the graphene surface by bombarding it with
electron beams and etching it with oxygen ions. When the light arrives,
the electrons in graphene nanostructures begin to oscillate. The
phenomenon concentrates light into tiny spots, which are comparable with
the dimensions of the target molecules making it possible to detect
nanometric compounds in proximity to the surface.

【gas transmitter,gas sensor,gas sensor suppliers, humidity sensors suppliers, infrared sensors suppliers】Touch IC developers turning to fingerprint sensors|en.ofweek.com
(Touch IC designers are banking on fingerprint sensors to shore up profitability)
With
China handset brand vendors starting to launch flagship products with
fingerprint sensors in the second half of 2014, touch controller IC
players who have seen thinning profitability have been aggressively
developing fingerprint sensor solutions.
During
a recent visit to Southern China's touch control supply chain,
Digitimes Research found that China-based touch solution developer
Goodix will be able to receive fingerprint sensor
solution orders for mid-range smartphones from China brand vendors in
the second half of 2015 thanks to its glass-covered fingerprint sensor technology, and the company will also surpass Sweden-based FPC to become the largest fingerprint sensor solution provider in China.
China's
major online payment players such as Alipay and China UnionPay are
coming close to finalizing fingerprint-certified payment standards. In
addition to unlocking smartphones, the fingerprint data input will also
serve as a certification method for online payment, prompting China's
smartphone brand vendors to adopt fingerprint sensor functionality into their CNY1,000 (US$161) mid-range smartphones.
Therefore,
creating a fingerprint sensor technology that is reliable and low cost
has become a major task for related players in the fingerprint sensor
industry in the second half of 2015.
Among
fingerprint sensor technologies in terms of contact surfaces, four major
solutions - from top-end to entry-level - are commonly used by
developers: sapphire, glass, ceramic and film coating. In 2014, sapphire
and film coating solutions both entered mass production and were
adopted in several mobile devices.
However,
sapphire solutions carry high costs and film coating can easily flake
off. The chance of glass and ceramic solutions' penetration into the
midrange smartphone segment in second-half 2015 will depend on the
R&D and mass production schedules for such technologies.
Currently,
within China's major touch controller IC designers, Goodix mainly
focuses on glass-type solutions; Holitech Technology, which has a tight
partnership with BYD, is only capable of providing film coating-based
solutions and is estimated to focus on the white-box smartphone segment;
and Silead is mainly developing ceramic-based solutions.
Thanks
to its solutions' high sensitivity and protection layer of over 300μm,
Goodix is currently the only player worldwide with the ability to mass
produce glass-based fingerprint sensor solutions.
Glass
has a good optical behavior and strong wear- and impact-resistance, and
it is much cheaper than sapphire. Glass solutions have received orders
from China-based major smartphone brand vendors such as Xiaomi and
Huawei and will be adopted into their mid-range smartphones in the
second half of 2015.
In 2014, Huawei used FPC's
fingerprint sensors, but the competition from Goodix in the mid-range
smartphone market in 2015 is expected to greatly threaten FPC's
leadership in China's fingerprint sensor industry.

The study followed 33 patients for one year and focused on the diagnosis of solitary pancreatic cystic lesions using the Cellvizio confocal laser endomicroscopy platform. Cellvizio is made by Mauna Kea Technologies SA, which sponsored the study.
For the first time, the authors defined new criteria to classify malignant cysts and pseudocysts, and confirmed the characteristics of benign serous cysts, which were published earlier this year. Independent endoscopists validated these criteria, with a substantial agreement between the two groups of observers, according to Mauna Kea.
The company now aims to enroll 200 patients in a follow-up study, said founder and CEO Sacha Loiseau.
The research was published in Surgical Endoscopy (doi: 10.1007/s00464-015-4510-5).

【cnc machine supplier,cnc cutting machine supplier,CNC router suppliers,CNC controller suppliers】"Robots+ CNC machine" is not exactly intelligent manufacturing|en.ofweek.com
gongkong.ofweek.com reports: Under the guidance of intelligent
manufacturing, what will be the future of digital factory? During the
supporting forum of AMB China, Professor Zhang Shu, Tongji University
Ph.D., honorary director of the Institute of modern manufacturing
technology showed us a case: A factory with an area of only 1000 square
meters, produces one product per second, services for 60000 customers.
There are about 5000 data acquisition points to process about 50000000
data with 99.9998% product qualification rate. This is the digital model
factory in Chengdu established by Siemens. He suggested that domestic
enterprises adopting this sample.
Zhang Shu clarified the
concept of intelligent manufacturing. Not all “robot+ cnc machine” are
intelligent manufacturing. CNC must have sensor to have the ability of
sensing vibration, displacement and temperature.
“Internet
+ WiFi” is not intelligent manufacturing; it’s just the basic setting
of intelligent manufacturing. It’s just a means but not all. Apart from
the physical production process and physical equipment, the Internet can
produce nothing.
He said that Siemens digital
factory was a factory that “producing itself”. The product development
is based on software---digital design and virtual assembly. Product data
is connected through the internet to each responsible party such as
quality control, purchase and logistics with real time update. There are
thousands of sensors to collect operating mode data and monitor production status.
He
pointed out that China’s advancement of intelligent and industry 4.0
was based on the Internet of things and the wireless communication of
the information system. Intelligent manufacturing is a big opportunity
for Chinese enterprises. We should carry it out in a gradual way. The
primary task for China manufacturing is to accelerate the progress of
industry 2.0 and 3.0; improve the quality and reliability of products,
step out of the cycle of imitate and copy; to commit to innovation and
become a world player.

European researchers have developed a sensor made from graphene to
detect molecules such as proteins and drugs. The sensor is
reconfigurable and highly sensitive, “exploiting the unique electronic
and optical properties of graphene for a practical application,” a
release stated.
Teams from the Swiss University
EPFL (école Polytechnique Fédérale de Lausanne) and the Institute of
Photonic Sciences in Barcelona used graphene to improve upon infrared
absorption spectroscopy for molecule detection. Traditionally, this
method uses light to excite molecules, which vibrate differently
depending on their nature, and the vibration creates a unique signature
that can be read in reflective light.
(Graphene's
higher level of field confinement enables highly sensitive vibrational
spectroscopy and refractive-index based sensing. Source: EPFL)
This
method isn’t effective for nanometrically-sized molecules, which are
often significantly smaller than the 6 micron wavelength of the infrared
photon used to detect the molecule. Researchers found that graphene is
able to focus the light on a specific spot to accurately “hear” the
vibration of a nanometric molecule.
An EPFL publication stated:
When
the light arrives, the electrons in graphene nanostructures begin to
oscillate. This phenomenon, known as “localized surface plasmon
resonance,” serves to concentrate light into tiny spots, which are
comparable with the dimensions of the target molecules. It is then
possible to detect nanometric structures.
Potential
applications for the sensor range from detecting gas leakage, sensing
toxic and explosive gas, measuring and detecting DNA and proteins as
well as contaminants in water, according to the reports.
Graphene can be tuned to different frequencies by applying voltage — which is not possible with current sensors,
the release stated. As a result, the process can also show the nature
of the bonds that connect atoms in a molecule by assessing the nuances
between different vibrations.
When graphene's
electrons oscillate in different ways, it’s possible to "read" all the
vibrations of the molecule on its surface. "We tested this method on
proteins that we attached to the graphene. It gave us a full picture of
the molecule," said Hatice Altug, an associate professor in the
Bionanophotonic Systems Laboratory at EPFL.
Altug
said the graphene-based process could also work for polymers and many
other substances. The results of this study appeared in the journal
Science.

The Annual Meeting of the New Champions 2015 (also known as the
summer Davos Forum) kicked off on 9, Sep. in Dalian, China. Dr. Chunyuan
Gu, Chairman and President of ABB (China) Limited, was invited to
attend the meeting and shared his views on the development trend of the
industrial robot technology and its impact on the future development of
the manufacturing industry.
Dr. Chunyuan Gu shares his views at Dalian summer Davos Forum on developing trend of the robotics technology and its impact on the manufacturing industry
Established in 2007 as the foremost global gathering on science, technology and innovation, the Annual Meeting of the New Champions convenes the next generation of fast-growing enterprises shaping the future of business and society together with leaders from major multinationals as well as government, media, academia and civil society. This year is the 9th annual meeting, with the theme “Charting a New Course for Growth”. More than 1,500 business, politicians, academic and media leaders from more than 90 countries will participate in the three-day meeting.
At the session focusing on the future of manufacturing, Dr. Gu said: “Nowadays both industrial and consumer products are experiencing even faster upgrading and updating, while end users are putting higher requirements on the quality and personalization of products. Under the megatrend of Internet of Things, Services and People, smart technologies like industrial robots increasingly help the manufacturing industry shorten production cycles, improve productivity and product consistency, and cope with market challenges in an efficient and flexible way."
ABB has been advocating Internet of Things, Services and People to help customers integrate equipments, services and people via the Internet, control and communication systems. Industrial robots equipped with sensors and industrial software are undoubtedly playing an important role in the process.
When talking about the relationship between humans and robots in the manufacturing industry, Dr. Gu said: "Industrial robots are not simply used to replace human workers but to free people from backbreaking, boring and even dangerous tasks. In the process, both enterprises and employees will benefit together. At present, the new era of the “human-robot collaboration” has arrived, and ABB is leading this significant change."
In April 2015, ABB introduced a two-arm 14-axis industrial robot called YuMi, the world's first truly collaborative robot. With its human-friendly design, YuMi work collaboratively with humans. Industrial robots which were once imprisoned in "cages" because of safety reasons will co-work with human companions side by side in the open environment to complete the small parts assembly and many other operations together.
ABB robotics business established its R&D center and production base in Shanghai in 2005. To date, ABB Robotics Shanghai has produced more than 40,000 units. In August 2015, ABB set up ABB Robotics (Zhuhai) Ltd. in Zhuhai National Hi-Tech Industrial Development District, to support southern China, the region with the most developed manufacturing and light industries, to accelerate manufacturing transformation and upgrading.

【gas transmitter,gas sensor,gas sensor suppliers, humidity sensors suppliers, infrared sensors suppliers】Industrial Internet Drives Rapid Development of Sensor|en.ofweek.com
As reported by gongkong.ofweek.com, Miao Wei, the minister of MIIT
recently said that MIIT is considering intelligent manufacturing
development strategy and preparing intelligent manufacturing specialized
plan to promote the intelligentization transformation of traditional
equipment and launch intelligent workshop and intelligent plant pilot
projects on the important industries. In the same time, MIIT will
promote the development of industrial internet.
Some media believed that industrial internet is the combination fruit of global industrial system, advanced computing, analyzing, sensing technology and internet. It connects man and machine and stimulates productivity through software and big data analytics. Different from traditional internet companies like Google and Amazon who collect data by PC and mobile terminal backstage, industrial internet is on the base of IoT and industrial data analysis and collects data from sensors installed on running machines; the data can be transmitted in cloud storage in real time.
Compared to ordinary sensor, industrial sensor need better stability and sensibility since most of them are applied in severe environment, such as noisy production workshop and electric power monitoring. MEMS sensor features small size, light weight, low cost, low power dissipation, high reliability, easy access to mass production, which is a perfect choice for industrial internet development.

【gas transmitter,gas sensor,gas sensor suppliers, humidity sensors suppliers, infrared sensors suppliers】Dialog, Bosch collaborate on wireless sensor platform for IoT|en.ofweek.com
Helping meet strategic ambitions for the two companies, Dialog
Semiconductor plc and Bosch Sensortec GmbH have teamed up to produce a
wireless sensor platform for Internet of Things applications.
The two companies have produced a low-power printed circuit board measuring 14mm by 14mm that contains multiple inertial sensors from Bosch Sensortec and Dialog's DA14580 Bluetooth wireless transceiver.
The unit is suitable for gesture recognition in wearable computing devices and immersive gaming, including augmented reality, and for 3D indoor mapping and navigation, the companies said in a joint press release.
The Bosch Sensortec sensors are the BMM150 for 3-axis geo-magnetic field measurement, the BME280 pressure, humidity and temperature sensor, and the 6-axis BMI160 – a combination of a 3-axis accelerometer and 3-axis gyroscope in one chip. The resulting unit consumes less than 500-microamps from a 3V coin cell when updating and transferring all 12 channels of 16bit data wirelessly to a smartphone. The DA14580 SmartBond SoC integrates a Bluetooth Smart radio with an ARM Cortex-M0 application processor and intelligent power management.
Dialog has been contemplating involvement in the MEMS and IoT market for many years and now, through its intended acquisition of Atmel, it will become a supplier of microcontrollers to Bosch Sensortec, the leading MEMS supplier in the world.
The agreement also provides a complementary pairing of Bosch's position in MEMS with Dialog's position as a supplier of Bluetooth and power management ICs providing most of the skills necessary for wireless sensor nodes that can be customized in software running on a microcontroller.
"From our companies’ joint experience, we see many opportunities to deliver competitive advantages for our customers by creating smaller, highly integrated and more energy efficient smart connected solutions," said Udo-Martin Gomez, CTO of Bosch Sensortec, in a statement.

【lens for laser machine,laser Machine Lens,lens supplier,lens manufacturer,optical lens】Broadband Laser Aimed at Cancer Detection|en.ofweek.com
Mid-infrared (MIR) light is rich with molecular "fingerprint"
information that can be used to detect anything from atmospheric
pollutants to cancer cells.
While some lasers already operate in this region, enabling a variety of spectroscopy applications, their linewidth is relatively narrow. That means the types of substances they can detect at any given moment is limited.
Now a team of researchers from Germany and Spain has developed a laser system with phase-coherent emission from 6.8 to 16.4 μm and output power of 0.1 W. That is broad and powerful enough, they said, to detect subtle signs of cancer early in its development.
Molecules absorb portions of the MIR spectrum in ways that are unique to their atomic structures. This provides a means of identifying them with great specificity, even in low concentrations.

Cancer causes subtle modification in protein structure and content within a cell," said professor Dr. Jens Biegert, a group leader at the Institute of Photonic Sciences (ICFO) in Barcelona. "Looking at only a few nanometer range, the probability of detection is extremely low. But comparing many of such intervals, one can have an extremely high confidence level."
The new laser system generates MIR pulses via difference-frequency generation driven by the nonlinearly compressed pulses of a Kerr-lens mode-locked Yb:YAG thin-disc oscillator. It features a repetition rate of 100 MHz and pulse durations of 66 fs — so short that the electric field oscillates only twice per pulse.
A new laser system emits ultrashort pulses of mid-infrared light. These pulses can be used to detect trace molecules in gaseous and liquid media. Courtesy of Thorsten Naeser/Ludwig Maximilian University.
"Since we now possess a compact source of high-intensity and coherent infrared light, we have a tool that can serve as an extremely sensitive sensor for the detection of molecules, and is suitable for serial production," said project leader Dr. Ioachim Pupeza, a staff scientist at Ludwig Maximilian University of Munich (LMU).
The LMU and ICFO researchers aim to use their MIR laser to identify and quantify disease markers in exhaled air. Many diseases, including some types of cancer, are thought to produce specific molecules that end up in the air we expel from our lungs.
"We assume that exhaled breath contains well over 1000 different molecular species," said Dr. Alexander Apolonskiy, an LMU group leader.
However, the amount of molecular biomarkers present in exhaled breath is extraordinarily low, meaning a diagnostic tool would need to be capable of detecting concentrations of at least one part per billion. The next step will be to couple the new laser system with a novel amplifier that would increase its brightness and boost sensitivity one part per trillion.
Detecting MIR signatures
The new laser's output spans more than one octave. Until now, the researchers said, such broadband emission has only been available from large-scale synchrotron sources.
Other more compact MIR sources, such as quantum cascade lasers (QCLs), have narrower linewidths. Tuning them to different sensing bands is time-consuming, and combining multiple QCLs emitting in different parts of the MIR would be cost-prohibitive, Biegert said.
Meanwhile, the new laser system's 100-MHz pulse train is hundreds to thousands of times more powerful than state-of-the-art frequency combs that emit in the same range, the researchers said.
Detecting broadband MIR signals presents its own problems, however. Detectors for this region have poor signal-to-noise ratios unless cooled with liquid nitrogen, the researchers said.
In this case, electro-optical sampling proved to be a better option. Well-established for the terahertz range, the technique is less common in the fingerprint region.
"In the MIR range, there are not many groups who have implemented this already, because you need a broadband, phase-stable MIR pulse and an ultrashort sample pulse at the same time, which is quite challenging," Pupeza said.
Having solved that problem with their broadband laser, the team now could use electro-optical sampling to extract the data they wanted.
In a nutshell, the process works like this: The electric field of an MIR pulse alters the birefringence of a crystal. This change can be measured by observing how the polarization of slightly shorter near-infrared (NIR) pulse is changed while propagating through the same crystal at the same time. In the end, only the NIR pulse is measured directly.
"Therefore, one big advantage is low-noise detection in the NIR, even though one obtains information on spectral components in the MIR," said Ioachim Pupeza. "You only need to perform a Fourier transform numerically to get the spectrum of the pulse once you have its electric field."
The research was published in Nature Photonics (doi: 10.1038/nphoton.2015.179).

【cnc machine manufacturer,cnc cutting machine manufacturer,CNC router manufacturer】The Practical Application of Industry 4.0|en.ofweek.com
With industry terms being bandied about like Internet of Things (IoT)
and Industry 4.0, it might not always be easy to get a handle on what
they really mean for manufacturing. In an effort to show its customers
the practical application of Industry 4.0, Bosch Rexroth and distributor
Morrell Group put together a show this week at Morrell’s facilities in
Auburn Hills, Mich., to not only explain the products and capabilities
that have an impact on these advances, but also give them a chance to
see everything up close.
With a theme of “Smart Factory Is Now,” Rexroth and Morrell wanted to be able to demonstrate the realities of what IoT capabilities really mean in a manufacturing environment—how the merging of information technology (IT) and operation technology (OT) can benefit production.
"I think we know now that both of those groups benefit when they work together well, and that’s what the Smart Factory is,” said Scott Hibbard, vice president of technology—factory automation for Bosch Rexroth Americas, during a press preview the day before the Automation Open House. The Smart Factory is not a new concept, he added, “but the definition of Smart Factory is changing, and changing quickly.”
The Smart Factory should be smart in many ways, Hibbard noted. It should make optimal use of all resources; it should be environmentally smart, and not just to meet codes or regulations; quality should be ensured upfront rather than enforced later through corrective action; it should be predictive, providing continuous improvement; and it needs to communicate information in real time.
Bosch Rexroth was recognized earlier this year with an award for its Industry 4.0 assembly line that integrates human, machine and product to economically manufacture customized products. Demonstrating the concept at Morrell’s facilities, Bosch showed the ease of making customized products—memory sticks or flashlights in a variety of colors, in this case—on a single machine. The separate stations on the machine operate autonomously, communicating with each other to carry out the manufacturing operation.
Bosch pairs its motion logic system IndraMotion MLC with the business rules management components of Bosch Software Innovations’ IoT Suite to combine machine events and IT processes using rules and services. The user can create models for the required rules using intuitive graphic tools and then port the models to the controller. The rules run alongside the PLC program directly on the controller. Then machine data can be analyzed during production to generate decisions such as automatic material supply or machine optimization.
The system is highly flexible, letting the user change existing rules at any time, create a model for new rules and transfer these onto the controller even during operation. This enables individual adjustments to be made dynamically, without making machine program changes.
A key to making this all work is the Open Core Engineering (OCE) capability that the MLCs have. OCE supports a broad range of protocols and programming languages to make it easier for controls and drives to bridge the gap between PLC-based automation and the IT world.
As part of a much larger initiative within the company, “Rexroth has developed libraries to support many different data environments,” Hibbard said, making reference to the poor computer science grad who starts his new job in manufacturing only to be told he has to program in a language he hasn’t learned. “Why not let the guy who’s gone to school to learn how to manipulate data program it in the language he’s learned it in?” he asked.
A recently announced partnership with National Instruments (NI) uses the Open Core Interface in a LabView programming environment without having to write PLC code. "Even motion can be conducted directly from there,” Hibbard added.
"What Open Core Engineering offers, it opens up the manufacturing world to a whole new series of programmers,” Hibbard said during a panel discussion. With OCE tools, he added, “kids are spinning motor shafts in minutes. Now small companies can do it too. What does this mean for the future?”
Looking to the future for customers big and small, Bosch Rexroth and Morrell Group are trying to cut past the hype surrounding IoT, Industry 4.0, Smart Factory, what have you. “Everybody’s heard about something different. A lot of those terms all get mixed into one little blending pot,” said Mark Majewski, vice president of automation and defense sales for Morrell. “Our job is to educate the people about what’s available today and what might be available in the future, and more where it’s useful.”
Just collecting data isn’t useful. “Ten years ago, everybody wanted more and more diagnostics,” Majewski said. “The reality is, what did they ever do with it? We were giving them all this information, and they didn’t know what to do with it. How do you take this information and be able to do something useful with it?”
Bosch is trying to drive customers away from scheduled maintenance checks, Hibbard said. “Certainly, you don’t want to wait until something breaks. Our part of that is to develop that data,” he said. “Twenty to 30 years ago in this town, people were saying we need to collect all the information we can off the machine. After that, we’ll figure out how to analyze it. Somewhere along the line, people lost interest and changed channels. We took that same idea and moved it down into the devices.”

With a theme of “Smart Factory Is Now,” Rexroth and Morrell wanted to be able to demonstrate the realities of what IoT capabilities really mean in a manufacturing environment—how the merging of information technology (IT) and operation technology (OT) can benefit production.
"I think we know now that both of those groups benefit when they work together well, and that’s what the Smart Factory is,” said Scott Hibbard, vice president of technology—factory automation for Bosch Rexroth Americas, during a press preview the day before the Automation Open House. The Smart Factory is not a new concept, he added, “but the definition of Smart Factory is changing, and changing quickly.”
The Smart Factory should be smart in many ways, Hibbard noted. It should make optimal use of all resources; it should be environmentally smart, and not just to meet codes or regulations; quality should be ensured upfront rather than enforced later through corrective action; it should be predictive, providing continuous improvement; and it needs to communicate information in real time.
Bosch Rexroth was recognized earlier this year with an award for its Industry 4.0 assembly line that integrates human, machine and product to economically manufacture customized products. Demonstrating the concept at Morrell’s facilities, Bosch showed the ease of making customized products—memory sticks or flashlights in a variety of colors, in this case—on a single machine. The separate stations on the machine operate autonomously, communicating with each other to carry out the manufacturing operation.
Bosch pairs its motion logic system IndraMotion MLC with the business rules management components of Bosch Software Innovations’ IoT Suite to combine machine events and IT processes using rules and services. The user can create models for the required rules using intuitive graphic tools and then port the models to the controller. The rules run alongside the PLC program directly on the controller. Then machine data can be analyzed during production to generate decisions such as automatic material supply or machine optimization.
The system is highly flexible, letting the user change existing rules at any time, create a model for new rules and transfer these onto the controller even during operation. This enables individual adjustments to be made dynamically, without making machine program changes.
A key to making this all work is the Open Core Engineering (OCE) capability that the MLCs have. OCE supports a broad range of protocols and programming languages to make it easier for controls and drives to bridge the gap between PLC-based automation and the IT world.
As part of a much larger initiative within the company, “Rexroth has developed libraries to support many different data environments,” Hibbard said, making reference to the poor computer science grad who starts his new job in manufacturing only to be told he has to program in a language he hasn’t learned. “Why not let the guy who’s gone to school to learn how to manipulate data program it in the language he’s learned it in?” he asked.
A recently announced partnership with National Instruments (NI) uses the Open Core Interface in a LabView programming environment without having to write PLC code. "Even motion can be conducted directly from there,” Hibbard added.
"What Open Core Engineering offers, it opens up the manufacturing world to a whole new series of programmers,” Hibbard said during a panel discussion. With OCE tools, he added, “kids are spinning motor shafts in minutes. Now small companies can do it too. What does this mean for the future?”
Looking to the future for customers big and small, Bosch Rexroth and Morrell Group are trying to cut past the hype surrounding IoT, Industry 4.0, Smart Factory, what have you. “Everybody’s heard about something different. A lot of those terms all get mixed into one little blending pot,” said Mark Majewski, vice president of automation and defense sales for Morrell. “Our job is to educate the people about what’s available today and what might be available in the future, and more where it’s useful.”
Just collecting data isn’t useful. “Ten years ago, everybody wanted more and more diagnostics,” Majewski said. “The reality is, what did they ever do with it?

IMAGE: Fiber optics and a new stretchable optical sensor can improve touch sensation in robotic hands. (Image credit: CMU)
Carnegie Mellon University (CMU; Pittsburgh, PA) researchers have developed a three-fingered soft robotic hand with multiple embedded fiber-optic sensors as well as a new type of stretchable optical sensor uniquely suited for use in robotic hands.
By using fiber optics, the researchers were able to embed 14 strain sensors into each of the fingers in the robotic hand, giving it the ability to determine where its fingertips are in contact and to detect forces of less than a tenth of a newton. In addition, a new stretchable optical sensing material not yet incorporated in the current version of the hand could potentially be used in a soft robotic skin to provide even more feedback.
"If you want robots to work autonomously and to react safely to unexpected forces in everyday environments, you need robotic hands that have more sensors than is typical today," said Yong-Lae Park, assistant professor of robotics. "Human skin contains thousands of tactile sensory units only in the fingertip and a spider has hundreds of mechanoreceptors on each leg, but even a state-of-the-art humanoid such as NASA's Robonaut has only 42 sensors in its hand and wrist."
Adding conventional pressure or force sensors is problematic because wiring can be complicated, prone to breaking, and susceptible to interference from electric motors and other electromagnetic devices. But a single optical fiber can contain several sensors; all of the sensors in each of the fingers of the CMU hand are connected with four fibers, although, theoretically, a single fiber could do the job, Park said.
The Carnegie Mellon researchers discussed the robotic hand, developed together with researchers at Intelligent Fiber Optic Systems Corp., with support from NASA, Sept. 29 at the IEEE International Conference on Intelligent Robots and Systems, IROS 2015, in Hamburg, Germany. A report on the highly stretchable optical sensors was presented Oct. 1 at the same conference.
Each of the fingers on the robotic hand mimics the skeletal structure of a human finger, with a fingertip, middle node, and base node connected by joints. The skeletal "bones" are 3D-printed hard plastic and incorporate eight sensors for detecting force. Each of the three sections is covered with a soft silicone rubber skin embedded with a total of six sensors that detect where contact has been made. A single active tendon works to bend the finger, while a passive elastic tendon provides opposing force to straighten the finger.
The hand, developed with mechanical engineering students Leo Jiang and Kevin Low, incorporates commercially available fiber Bragg grating (FBG) sensors, which detect strain by measuring shifts in the wavelength of light reflected by the optical fiber.
Despite their advantages, conventional optical sensors don’t stretch much--glass fibers stretch hardly at all and even polymer fibers stretch typically only 20-25%, Park noted. That is a limiting factor in a device such as a hand, where a wide range of motion is essential. Park has previously developed highly stretchable microfluidic soft sensors--membranes that measure strain via liquid-conductor-filled channels--but they are difficult to make and can cause a mess if the liquid leaks out.
So Park, working with mechanical engineering students Celeste To from CMU and Tess Lee Hellebrekers from the University of Texas, invented a highly stretchable and flexible optical sensor, using a combination of commercially available silicone rubbers. These soft waveguides are lined with reflective gold; as the silicone is stretched, cracks develop in the reflective layer, allowing light to escape. By measuring the loss of light, the researchers are able to calculate strain or other deformations.
Park said this type of flexible optical sensor could be incorporated into soft skins. Such a skin would not only be able to detect contact, as is the case with the soft components in the CMU hand, but also measure force.

【gas sensor,gas transmitter, gas sensor suppliers,humidity sensors suppliers, humidity sensors manufacturers】Chinese OEM to dominate mobile sensors purchase, displace Apple and Sumsung|en.ofweek.com
As ee.ofweek.com reports: Chinese mobile OEM will displace Apple and
Samsung to become the main driving force of mobile sensor purchasing,
said IHS.
In 2014, Apple's purchase amount of mobile sensor reached to almost 50% of the total while Samsung occupied 20% above. But IHS predicts that Chinese mobile OEM will replace Apple and Samsung by 2019. According to IHS, market share of Apple has been declined since the 47% in 2014, which will be reduced to 34% in 2019; in the same time market share of Samsung will be reduced from 23% to 15%.
In the mean time, market share of Chinese OEM dominated by Xiaomi has grown from 20% in 2014 to 40% in 2019.
Samsung will encounter great challenge because its shipment continues to fall in a growing market. Samsung will meet competitive pressure from Apple in high-end market and challenge from Chinese competitors in low and mid-range mobile sensor market.
IHS said that in order to differentiate their own mobile sensor products, Chinese OEM are willing to try different new products, which makes China an ideal market for sensor suppliers who are trying to march into mobile sensor field. The Chinese government's support further drives the growth of local electronic component manufacturing and purchasing. However, at the moment only a few suppliers can provide limited product portfolio of sufficient demand and quality. It includes AACTechnologies, GoerTek, MEMSIC, QST and some startups in China.

【gas sensor supplier,sensor suppliers ,gas transmitter supplier,Infrared Sensors manufacturer】Chinese handset OEMs start to drive sensor demand|en.ofweek.com
Chinese handset OEMs are starting to take over from Apple and Samsung
as the drivers of sensor volumes for smartphones, according to IHS Inc.
In 2014 Apple bought nearly 50 percent of the sensors going into smartphones and Samsung more than 20 percent, but by 2019 Chinese handset OEMs will be displacing Apple and Samsung, IHS forecasts.
Apple's share of the market spending is set to go from 47 percent in 2014 to 34 percent in 2019, the market researcher said. Over the same time Samsung's share will decline from 23 percent to 15 percent.

Meanwhile Chinese original equipment manufacturers (OEMs) led by Xiaomi is set to go from 20 percent in 2014 to 40 percent in 2019.
Samsung is suffering because its unit shipments are falling in a rising market. It suffers from Apple's competition at the high-end and from competition from Chinese competitors in the low-end and mid-range smartphones.
China is proving a suitable market for sensor suppliers trying to enter the smartphone market as the Chinese OEMs are willing to try many novel sensors as they try to differentiate their phones, IHS said. The Chinese government’s decision to support local companies has led to an increase in local manufacturing and sourcing of electronic components.
However today there are only a handful of suppliers that can supply in sufficient volume and quality with a relatively narrow portfolio of products. These companies include AAC Technologies and GoerTek, for microphones; MEMSIC, for accelerometers and magnetometers; and QST and some other emerging Chinese startups for motion sensors.
"With the Chinese government’s strategic goal to increase the share of domestic suppliers, there is an opportunity for Chinese suppliers to expand their portfolios and become the preferred suppliers for Chinese OEMs," said Marwan Boustany, senior analyst with IHS Technology. At the moment, though, it seems that Chinese OEMs are happy to use any supplier that fulfils their volume, performance and price requirements."

【gas transmitter supplier,sensor suppliers ,Gas Sensor ,gas transmitter supplier】Highly flexible and wearable tactile sensor|en.ofweek.com
Source and top image: National University of Singapore
A team of scientists from the National University of Singapore (NUS) Faculty of Engineering has developed a wearable liquid-based microfluidic tactile sensor that is small, thin, highly flexible and durable. Simple and cost-effective to produce, this novel device is very suitable for applications such as soft robotics, wearable consumer electronics, smart medical prosthetic devices, as well as real-time healthcare monitoring.
Tactile sensors are data acquisition devices that detect and measure a diversity of properties arising from physical interaction and translate the information acquired to be analysed by an interconnected intelligent system. Conventional tactile sensors that are available today are typically rigid and in solid-state form, restricting various natural body movements when used and may also be subjected to plastic deformation and failure when pressure is exerted, resulting in compromises in conformability, durability and overall robustness.
Addressing the limitations of existing tactile sensors, a team of researchers led by Professor Lim Chwee Teck from NUS' Department of Biomedical Engineering achieves a significant technological breakthrough by adopting a liquid-based pressure sensing method in the design of such sensors.
Novel liquid-based pressure sensing element
The newly developed microfluidic tactile sensor is fabricated on a flexible substrate like silicone rubber, and uses non-corrosive, non-toxic 2D nanomaterial suspension in liquid form, such as graphene oxide, as the pressure sensing element to recognise force-induced changes.
The NUS team has put the device through rigorous tests and also subjected it to various strenuous deformations, such as pressing, bending or stretching, to validate the robustness and versatility of its invention. In fact, despite having placed the device under extreme abusive mechanical force, such as running a car tyre over it, the electrical output was highly uniformed and there was no damage to the functionality of the device.
From idea to market
The team's invention will further advance the applications of tactile sensors, which are already increasingly utilised for monitoring critical parameters in biomedical applications, especially for those that may come in contact with human skin or where human movement is highly versatile.
"This liquid-based microfluidic tactile sensor, which is the first of its kind, addresses an existing gap in the market. Being thin and flexible, the sensor gives a better fit when monitoring natural body movements. Its small size, durability and ease of production further differentiate this novel device from conventional tactile sensors. With the rapid advancement of healthcare and biomedical technologies as well as consumer electronics, we are optimistic about new possibilities to commercialise our invention," said Prof Lim.
The NUS team has already filed a patent for its creation and is also keen to explore licensing partnerships in commercial development. Earlier this year, it participated in InnovFest unBound, Asia's premier technology transfer event organised by NUS Enterprise aimed at showcasing Asian innovation to a global audience and taking technology out to the market.
