Bluetooth Baby

May 23, 2012 5:23 am | Comments

Checking the heart of the unborn baby usually involves a stethoscope. However, an inexpensive and accurate Bluetooth fetal heart rate monitoring system has now been developed by researchers in India for long-term home care. Details are reported in a forthcoming issue of the International Journal of Computers in Healthcare .


Protocol Enables Wireless and Secure Biometric Acquisition with Web Services

May 23, 2012 5:21 am | Comments

Researchers at the National Institute of Standards and Technology (NIST) have developed and published a new protocol for communicating with biometric sensors over wired and wireless networks—using some of the same technologies that underpin the web. The new protocol, called WS-Biometric Devices (WS-BD), allows desktops, laptops, tablets and smartphones to access sensors that capture biometric data such as fingerprints, iris images and face images using web services.


Getting in Tune: Researchers Solve Tuning Problem For Wireless Power Transfer Systems

May 23, 2012 5:19 am | by Researchers have shown that it is possible to transmit power wirelessly by using magnetic resonance. Even minor changes in how the transmitter or receiver is tuned, however, can result in faulty power transmission. | Comments

Researchers from North Carolina State University have developed a new way to fine-tune wireless power transfer (WPT) receivers, making the systems more efficient and functional. WPT systems hold promise for charging electric vehicles, electronic devices and other technologies. A new prototype developed at NC State addresses the problem by automatically – and precisely – re-tuning the receivers in WPT systems.


Quantum Computing: The Light At The End Of The Tunnel May Be A Single Photon

May 23, 2012 5:18 am | Comments

Quantum physics promises faster and more powerful computers, but quantum versions of basic logic functions are still needed to bring this technology to fruition. Researchers from the University of Cambridge and Toshiba Research Europe Ltd. have taken one step toward this goal by creating an all-semiconductor quantum logic gate, a controlled-NOT (CNOT) gate.


Navy Pilot Training Enhanced by AEMASE ‘Smart Machine’

May 23, 2012 5:15 am | Comments

Navy pilots and other flight specialists soon will have a new “smart machine” installed in training simulators that learns from expert instructors to more efficiently train their students. Sandia National Laboratories’ Automated Expert Modeling & Student Evaluation (AEMASE, pronounced “amaze”) is being provided to the Navy as a component of flight simulators.


Life-size 3-D Hologram-like Telepods May Revolutionize Videoconferencing in the Future

New device, developed by team of engineers led by Professor Amr Helmy (ECE), could bring quantum computing to your home or office In the age of high-speed computing, the photon is king. However, producing the finely tuned particles of light is a complex and time-consuming process, until now. Thanks to the work by a team of engineers led by Professor Amr Helmy of The Edward S.


X-rays Reveal Molecular Arrangements for Better Printable Electronics

May 23, 2012 5:01 am | Comments

    By employing powerful X-rays that can see down to the molecular level of organic materials used in printable electronics, researchers are now able to determine why some materials perform better than others. Their findings, published in the journal Nature Materials , could lead to cheaper, more efficient printable electronic devices.


Computing Experts Unveil Superefficient ‘Inexact’ Chip

May 23, 2012 4:59 am | Comments

Researchers have unveiled an “inexact” computer chip that challenges the industry’s 50-year pursuit of accuracy. The design improves power and resource efficiency by allowing for occasional errors. Prototypes unveiled this week at the ACM International Conference on Computing Frontiers in Cagliari, Italy, are at least 15 times more efficient than today’s technology.


Researchers Improve Fast-Moving Mobile Networks

May 23, 2012 4:55 am | Comments

Mobile ad hoc networks (MANETs) allow people in multiple, rapidly-moving vehicles to communicate with each other – such as in military or emergency-response situations. Researchers from North Carolina State University have devised a method to improve the quality and efficiency of data transmission in these networks.


Engineers Use Plasmonics to Create An Invisible Photodetector

May 22, 2012 5:15 am | Comments

It may not be intuitive, but a coating of reflective metal can actually make something less visible, engineers at Stanford and UPenn have shown. They have created an invisible, light-detecting device that can “see without being seen.” At the heart of the device are silicon nanowires covered by a thin cap of gold.


New Silicon Memory Chip Developed

May 22, 2012 5:05 am | by The first purely silicon oxide-based 'Resistive RAM' memory chip that can operate in ambient conditions – opening up the possibility of new super-fast memory - has been developed by researchers at UCL. | Comments

Resistive RAM (or 'ReRAM') memory chips are based on materials, most often oxides of metals, whose electrical resistance changes when a voltage is applied – and they "remember" this change even when the power is turned off. ReRAM chips promise significantly greater memory storage than current technology, such as the Flash memory used on USB sticks, and require much less energy and space.


Performance Boost for Microchips

May 22, 2012 5:03 am | Comments

The semiconductor industry is faced with the challenge of supplying ever faster and more powerful chips. The Next-Generation Lithography with EUV radiation will help meeting that challenge. Fraunhofer researchers have developed key components. Flat computers, powerful cell phones and tablets – the integrated circuits, our computers‘ power centers, are becoming increasingly smaller and more complex.


Technology Convergence May Widen the Digital Divide

May 22, 2012 4:47 am | Comments

Technology is helping communication companies merge telephone, television and Internet services, but a push to deregulate may leave some customers on the wrong side of the digital divide during this convergence, according to a Penn State telecommunications researcher. "Moving away from copper lines is an example of abandoning obsolete technology and embracing technology that is faster, better, cheaper and more convenient," said Rob Frieden, Pioneers Chair in Cable Television and professor of telecommunications and law.


Online Privacy: How to Control Your Personal Data
