Path Gain And SAR Analysis Of On-Body Antenna Optimized For Hearing Instrument Applications
2014-02-11 16:54:49| rfglobalnet Downloads
This presentation describes the simulation of one proposed antenna, designed to permit communication between devices in each ear. The design was simulated in the presence of a homogeneous SAM phantom and an anatomically correct, heterogeneous head model. Since the antenna exhibits different performance characteristics depending upon the head model used, a parameter sweep was conducted to determine the optimal configuration for each model. The simulation results illustrate the differences between the head models, suggesting a heterogeneous head model will yield more acceptable results and will improve the safety of the device when used by real human subjects.

FAA Clears Path for Installation of Angle of Attack Indicators in Small Aircraft
2014-02-05 06:00:00| Industrial Newsroom - All News for Today
By simplifying design approval requirements for angle of attack (AOA) indicators, FAA hopes to improve safety in small aircraft. AOA devices are cockpit instruments that supplement airspeed indicators and stall warning systems to alert pilots of low airspeed condition before dangerous aerodynamic stall occurs. Calling this "a win-win situation," U.S. DoT Secretary Anthony Foxx said, "we are improving safety by streamlining regulations and cutting red tape."<br /> This story is related to the following:Trade Associations

Will Verizon Follow AT&T's Price Cut Path?
2014-02-03 18:32:48| Telecom - Topix.net
AT&T Inc's plan to cut prices on its large shared data plans could prompt other U.S. carriers, particularly larger rival Verizon Wireless, to offer new discounts, analysts said.
Corridors to Survival: Charting a Path to Combat Climate Change in the Tropics
2014-02-03 11:40:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: The concept of habitat corridors in conservation has been around for a while. Its a topic at global climate talks and an issue for NGOs eager to create pathways for survival between protected areas. For all the talk, there hasnt been much research to help execute a plan. A team of scientists at Woods Hole Research Center in Falmouth, Mass., has stepped into this scientific vacuum in the tropics. Using newly available, high-resolution data sets of vegetation carbon stocks gleaned from satellite...
