A research group from the Cockrell School of Engineering at The University of Texas at Austin has developed a smaller, lighter and cheaper radio wave circulator for wireless devices. Researchers believe this device could transform telecommunications. Typically, radio wave devices are produced of magnetic materials, which are usually heavy, expensive and large. The circulator … [Read more...]
FAA Alters Regulations Regarding Use of Electronic Devices During Flights
The FAA announces airplane travelers will be able to use electronic devices throughout their entire flight very soon. A statement made by the FAA said it expects "many carriers will prove to the FAA that their planes allow passengers to safely use their devices in airplane mode, gate-to-gate, by the end of the year." Until now, airplane passengers in the U.S. were unable to … [Read more...]
New Field Generator Introduced to Industry
DARE!! Instruments presents its patented RadiField Triple A – a cost effective and efficient field generator. This RadiField Triple A is “no less than a revolution in EMC immunity testing,” according to researchers. Typically, immunity testing setups are complicated and involve an amplifier, coupler, RF power meters, interconnecting cables and a combiner; however, the … [Read more...]
'Tech Tidbit' – Hotels Introduce Convenient Smartphone Technology
Starting today, users will be able to use their smartphone to open doors at certain Starwood Hotels, such as Aloft, Element and W, by using a keyless entry application. The keyless entry app is convenient since it’s harder to lose a cell phone than a plastic room key and the smartphones cannot be demagnetized like the swipe cards. Hotel customers can also skip the check-in and … [Read more...]
'Tech Tidbit' – Cell Phone Charger Creates ‘Sure-Fire’ Problem in China
A showroom set in China caught on fire when a salesman tried to use a mobile charger to restart a dead car battery in a Cadillac Escalade before an exhibition. This occurred in an exhibition hall in Wuhan City, China. The Escalade quickly was engulfed in flames and the fire quickly escalated to a second car that had a leaking fuel pipe, causing the fire to spread even further. … [Read more...]
New Power MOSFET Introduced
A new power MOSFET, also known as the Si8457DB, has been released by Vishay Intertechnology, Inc. This 12 V Chipscale MICRO FOOT is intended to lengthen battery life and reduce power consumption in electronic devices. Features of the Si8457DB include a low on-resistance at 1.8 V, extra safety features, space savings, less power usage, an extremely low voltage drop, less wasted … [Read more...]
Life of Electronics Increased by 3 Times
Jaesang Lee, Electrical Engineering PhD Student, demonstrates use of blue PHOLEDs in the EECS Building on August 13, 2014. The blue PHOLEDs were developed in EECS Professor Stephen Forrest's lab groups and are for use in cell phones, tablets, and other electronics. The LEDs' lifetime has been enhanced by a factor of ten, allowing for more efficient use. Credit: Joseph Xu, … [Read more...]
New Smartphone Technology Offers Endless Possibilities
Researchers at MIT have partnered with the Tangible Media Group and the Fluid Interface Group to develop THAW – a smartphone system that allows “Smartphone users to seamlessly interact with other computer devices via their screen.” This new technology could grow into an even bigger accomplishment when you sit and consider its future possibilities. “THAW works by projecting a … [Read more...]
4G Study Highlights Need for More Thermal Loss Research
A new study from Danish researchers suggests the ongoing push towards global 4G roaming and high-quality, frequency-reconfigurable antennas will need to account for new loss capacities not considered by previous technology. The worldwide demand for 4G technology and higher data rates in cell phones has led to a new, urgent need for frequency-reconfigurable or tunable antennas. … [Read more...]
PIN Diode Switches Cover Up to 12 GHz with Isolation as High as 90 dB
Pasternack Enterprises, Inc., has introduced a new family of consisting of three low insertion loss, high isolation and high speed modules that cover a frequency range of 1 to 12 GHz. The new RF switches feature very high port-to-port isolation of greater than 90 dB at 1-2 GHz, 80 dB at 2-4 GHz and 75 dB at 6-12 GHz, while insertion loss varies between 1.0 dB and 2.5 dB … [Read more...]
