New System Could Prolong Power in Mobile Devices
Posted in Electronics & Computers, Electronic Components, Power Management, PCs/Portable Computers, Semiconductors & ICs, News on Monday, 27 October 2014
Researchers from The University of Texas at Dallas have created technology that could be the first step toward wearable computers with self-contained power sources or, more immediately, a smartphone that doesn’t die after a few hours of heavy use. The technology taps into the power of a single electron to control energy consumption inside transistors, which are at the core of most modern electronic systems.

Wireless Sensing Lets Users “Train” Smartphones for Gesture Control
Posted in Electronics & Computers, PCs/Portable Computers, Sensors, Detectors, Communications, Wireless, RF & Microwave Electronics, Antennas, News on Monday, 06 October 2014
University of Washington researchers have developed a new form of low-power wireless sensing technology that could soon let users “train” their smartphones to recognize and respond to specific hand gestures near the phone. The “SideSwipe” technology uses the phone’s wireless transmissions to sense nearby gestures, so it works when a device is out of sight in a pocket or bag and could easily be built into future smartphones and tablets.

Astronauts to Test Free-Flying Robotic 'Smart SPHERES'

Three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion, computer, navigation equipment, and physical and electrical connections for hardware and sensors for various experiments.

Aboard Orbital Sciences Corp.'s second contracted commercial resupply mission to the space station, which arrived to the orbital laboratory on July 16, NASA's Ames Research Center in Moffett Field, California, sent two Google prototype Project Tango smartphones that astronauts will attach to the SPHERES for technology demonstrations inside the space station.

By connecting a smartphone to the SPHERES, the technology becomes "Smart SPHERES, " a more "intelligent" free-flying robot with built-in cameras to take pictures and video, sensors to help conduct inspections, powerful computing units to make calculations and Wi-Fi connections to transfer data in real time to the computers aboard the space station and at mission control in Houston.

In a two-phase experiment, astronauts will manually use the smartphones to collect visual data using the integrated custom 3-D sensor to generate a full 3-D model of their environment. After the map and its coordinate system are developed, a second activity will involve the smartphones attached to the SPHERES, becoming the free-flying Smart SPHERES. As the free-flying robots move around the space station from waypoint to waypoint, utilizing the 3-D map, they will provide situational awareness to crewmembers inside the station and flight controllers in mission control. These experiments allow NASA to test vision-based navigation in a very small mobile product.

Motion-Sensing Keyboard Lets Users Hover and Swipe
Posted in Electronics & Computers, PCs/Portable Computers, Mechanical Components, Sensors, Software, Mathematical/Scientific Software, News on Wednesday, 28 May 2014
Microsoft engineers have developed a new type of augmented mechanical keyboard, sensing rich and expressive motion gestures performed both on and directly above the device. A low-resolution matrix of infrared (IR) proximity sensors is interspersed with the keys of a regular mechanical keyboard. This results in coarse, but high frame-rate motion data.

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.

Engineers Design Software Tools to Secure Tactical Smartphones
Posted in Electronics & Computers, PCs/Portable Computers, Software, Defense, News on Tuesday, 01 April 2014
Suraj Kothari's talk of smartphone security quickly took a turn toward sabotage and worst-case scenarios. What happens, he asked, if a soldier's smartphone is hacked for its GPS data? What happens if an attacker drains the battery in a general's phone and essential communication is cut off? Or, what happens if a hacked phone provides false information during a military mission?

Smartphones Become "Eye-Phones" to Capture Images of the Eye
Posted in Electronics & Computers, PCs/Portable Computers, Imaging, Medical, Patient Monitoring, Diagnostics, News on Tuesday, 01 April 2014
Two inexpensive adapters enable a smartphone to capture high-quality images of the front and back of the eye, enabling users to share them securely with other health practitioners or store it in a patient's electronic record. The researchers see this technology as an opportunity to increase access to eye-care services as well as to improve the ability to advise on patient care remotely.
