Wireless sensor nodes (WSN) have been used for decades to measure physical and environmental conditions. Small, low power, wearable sensors to monitor a patient's heart, muscle, or brain activity as they conducted their daily activities has been more challenging to develop. That is until now.
The 32-bit event-driven processor architecture from XMOS offers an alternative approach to embedded computing solutions. Instead of the operating system managing and servicing interrupts, the processor creates and looks for events.
The AMD Radeon E6760 GPU from Advanced Micro Devices Inc. targets performance-driven embedded graphics and GPU computing applications. The GPU, packaged as a multi-chip module (MCM) with a ball grid array (BGA) footprint, features 1 GB of GBBR5 memory and a power dissipation of 35 W.
As demands grow for portable sensing equipment in the medical equipment and other sectors, instrument designers will demand better power efficiency from the electronic components they specify for their instruments. ON Semiconductor believes its Q32M210 family of mixed-signal microcontrollers will fill a niche for precision measurement and monitoring.
Microphones equipped with microelectromechanical systems (MEMS) are used in most audio applications that require active noise canceling (ANC), and are found in headphones/headsets, mobile phones, laptop computers, and tablets. To distinguish its products in the MEMS microphone market, Geneva- based STMicroelectronics (ST), focused on differentiation and innovation.
Ferroelectric random access memory or FRAM, is a non-volatile memory that can retain data without power. The device operates when ferroelectric materials switch polarity in an electric field.
Omega’s new CL540ZA thermocouple simulator can be used to calibrate a thermocouple input instrument and can be used for measuring temperature in a manufacturing facility.
Heidenhain has increased the functionality of its Profibus rotary encoders. The encoders that feature the Profibus interface now support the DP-V2 encoder profile which makes them ready for robot control and production technology.
A Russian astronaut was about to release a boxy 57-pound satellite Wednesday when flight controllers called off the operation. Someone had noticed from TV images that the micro-satellite, a prototype for a series of educational satellites, was missing one of its two antennas.
With one of the fastest-aging populations in the world, Japan is using robotics to provide automated care solutions. The latest effort at RIKEN, a robot able to lift a human, relies on the first capacitance-type tactile sensors made entirely of rubber to provide the necessary soft touch.
The PyLoN series is a new line of controllerless, cryogenically cooled CCD cameras from Princeton Instruments designed for quantitative spectroscopy at high sensitivity levels.
SensorDynamics, a manufacturer of MEMS and wireless semiconductor products, announced that it was acquired by Maxim Integrated Products, a manufacturer of analog and mixed-signal semiconductor products. Maxim is paying approximately $130 million plus the assumption of about $34 million in debt to acquire SensorDynamics.
Magma Design Automation Inc., a provider of chip design solutions, announced TSMC has included the QCP extractor in TSMC’s quarterly EDA qualification report for 28-nm integrated circuits (ICs).
Researchers from North Carolina State University have developed a memory device that is soft and functions well in wet environments—opening the door to a new generation of biocompatible electronic devices.
A small company in Massachusetts has built what they believe is the most powerful direct-diode laser in the world. Their technology, developed at MIT, employs an optical system to couple multiple individual semiconductor laser beams into a single stronger one that rates at 1,000 W in a 200-?m fiber.
Arizona State University researchers have released a striking image of the Moon’s prominent impact crater Tycho, taken by the Lunar Reconnaissance Orbiter Camera last month. The photograph was planned for its dramatic effect. The boulder in this closeup detail is about 400 feet wide.
In Europe, where there are an estimated 300,000 contaminated sites that require testing and treating before further development, a new portable tester that uses live bioluminescent bacteria to assess toxicity has proven popular. With tests taking only 12 to 15 minutes per sample, the device could be used to find out, in less than a day, whether a field contains carcinogenic toxins, and map precisely where the hot spots of the pollution are.
Researchers at Georgia Tech have discovered a way to capture and harness energy transmitted by such sources as radio and television transmitters, cell phone networks, and satellite communications systems. By collecting this extra ambient energy from the air, the engineeres have found a way to provide power for their printed wireless sensors.
Lumex and element14 have announced a strategic partnership created to enhance LED and LCD product portfolios across Asia Pacific. The new partnership strengthens the global distribution agreement between the two companies.
The Federal Aviation Administration (FAA) has mandated that by 2020, all commercial aircraft must be equipped with a new tracking system that broadcasts GPS data, providing more accurate location information than ground-based radar. In anticipation of the deadline, the FAA has also charged Massachusetts Institute of Technology (MIT) researchers with leading an investigation of the system’s limits and capacities.
Cataracts are the leading cause of preventable blindness worldwide. But the standard test to detect the cloudy patches in the eye's lens requires a $5,000 piece of equipment called a slit lamp, and a trained physician to interpret its results. Now a team of MIT researchers has developed a simple device that can clip onto an ordinary smartphone (or smart device such as an iPod) and provide a diagnosis of cataracts within a few minutes.
Building on a revolutionary 3-D microscope technique that introduced the function of time, chemistry Nobel Laureate Ahmed H. Zewail and his colleagues have overcome limitations to supply high-resolution imaging information of nanoscale objects in four dimensions.
The pen may have bested the sword long ago, but now it's challenging wires and soldering irons. Univ. of Illinois engineers have developed a silver-inked rollerball pen capable of writing electrical circuits and interconnects on paper, wood, and other surfaces. The pen is writing whole new chapters in low-cost, flexible, and disposable electronics.
The eye of the peacock mantis shrimp has led an international team of researchers to develop a two-part waveplate that could improve CD, DVD, blu-ray, and holographic technology, creating even higher definition and larger storage density.
A team of researchers from NIST, George Mason Univ., and the Univ. of Maryland has made nano-sized sensors that detect volatile organic compounds that offer several advantages over today's commercial gas sensors, including low-power room-temperature operation and the ability to detect one or several compounds over a wide range of concentrations.
