Quantum Navigation Technologies Could Outmode GPS
With the rise of smartphones and other handheld wireless devices, GPS technology has experienced an explosion in popularity, becoming near-omnipresent in the daily lives of many consumers. However, its limitations, including its inability to work underwater and its susceptibility to both accidental and deliberate signal interference, could pave the way for a new, more accurate … [Read more...]
Webinar on PCB Suppression of ICs with BGA or Multiple Power Rails
On June 25, 2014, Keith Armstrong will present a live webinar on “PCB Suppression of ICs with BGA or Multiple Power Rails." Overview: Most EMC design textbooks that cover printed circuit board (PCB) design and layout – including mine – do not cover the special EMC issues associated with Ball Grid Array devices (BGAs), so this webinar covers PCB design techniques that will … [Read more...]
British Researchers to Study Effects of Cell Phones on Teen Brain Development
Scientists in the UK are conducting the largest study to date on the effects of cell phone usage on adolescent and teenage brain development. The study, called SCAMP (Study of Cognition, Adolescents and Mobile Phones), will follow a group of 2,500-3,000 students in the greater London area, charting changes in brain development from Grade 7 to Grade 9. SCAMP’s mission, stated … [Read more...]
High-Surge Transient Protection Array Safeguards Communications Transceivers
Semtech Corporation, a supplier of analog and mixed-signal semiconductors, has announced the release of the TClamp1202P, the smallest low-cap, high-surge, 12V (Vrwm) transient voltage protection array in its class. Offering 100A (8x20µs waveform) of surge immunity in an ultra-small 2mm x 2mm package, the TClamp1202P can be used in a wide range of industrial and … [Read more...]

Dead Spacecraft Gives Insight into ‘Bermuda Triangle of Space’
A decade-old European satellite has given Italian scientists a detailed look into a dangerous radiation zone located a few hundred kilometers above the coast of Brazil. Known as the South Atlantic Anomaly (SAA), or “Bermuda Triangle of Space,” the region has reportedly caused satellites and telescopes to malfunction and temporarily affected astronauts’ eyesight. According to … [Read more...]
Combining Near- and Far-Field Waves to Power Medical Devices
Video: Stanford University in California Researchers have demonstrated a method of transferring wireless energy to a medical device implanted inside a living animal. The new system, which uses the same amount of power as a cell phone to transmit energy to implanted chips roughly the size of a grain of rice, is the culmination of years of work by Ada Poon, assistant professor … [Read more...]
Dual-Channel Active EMI and ESD Suppressor for Ethernet Applications
Product supplier Digi-Key now carries Akros Silicon’s new AS1602, a single-chip, highly-integrated CMOS solution for EMI and ESD suppression in Ethernet applications. The AS1602 can be used in any type of 10Base- T/100Base-TX/1000Base-T systems, in both Power-over-Ethernet (PoE) and non-PoE ports.
