Low-Cost, High-Resolution Time-Measurement Application

July 16, 2009 10:11 am | by Jim Bartling, Microchip Technology | Articles | Comments

Time Domain Reflectometry (TDR) is a measurement of the impedance of a transmission line using the reflected energy of a pulse sent down that transmission line.  As a pulse is sent down a transmission line, it travels at the speed of light for the media it is in (typically, 60% to 80% of the speed of light in free space). As the pulse arrives at an impedance, mismatch energy is reflected back to the pulse source and arrives at a time

Scientists Discover Light Force with 'Push' Power

July 16, 2009 10:03 am | News | Comments

A team of Yale University researchers has discovered a "repulsive" light force that can be used to manipulate components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity.

Front End IC Simplifies Board Design

July 16, 2009 8:57 am | Product Releases | Comments

Eliminating the need for RF component matching, the NEC UPG2253T6S Front End IC combines a power amplifier, low pass filter, and two SPDT switches into a single chip. Well-suited for Bluetooth and ZigBee applications, the device’s 3 mm x 3 mm x 0.7 mm package size enables product designs with tiny footprints

Leveraging COTS Technology to Advance Stand-Alone Rugged Boxes

July 16, 2009 7:49 am | by Mike Southworth, Parvus | Articles | Comments

Technology developments that reduce complexity and enhance usability are always a welcome addition to rugged applications, since fewer parts means improved reliability. This truth is especially evidenced by the increasing availability of stand-alone rugged boxes. The development of stand-alone rugged boxes has provided a singular computing solution for rugged applications where reliable high performance computing is a must. Previously, rugged computing devices were dispersed among several different computing units

Latest iTunes Release Ejects Palm Pre Users

July 16, 2009 6:56 am | by by Jason Lomberg, Technical Editor | News | Comments

Palm Pre users who enjoy syncing music and video with iTunes are in trouble—version 8.2.1 of the software locks out the Pre. Previously, Pre users were able to use rival software on their Palm smartphone, a most unusual arrangement. It’s not that archrivals don’t ever do business together. After all, this is much cross-pollination between Microsoft and Apple products. But arguably, the iPod’s greatest asset is its intuitive iTunes software. The hardware itself is somewhat ubiquitous.

VGA Offers Adjustable Gain Control

July 16, 2009 5:56 am | Product Releases | Comments

Optimized for operation from 1 MHz to 500 MHz, the LTC6412 800-MHz analog-controlled VGA from Linear Technology consumes 110mA on a 3.3V supply and provides continuous gain adjustment from -14 dB to 17 dB.

Damage eyed as shuttle heads toward space station

July 16, 2009 5:30 am | by MARCIA DUNN, AP Aerospace Writer | News | Comments

Space shuttle Endeavour rocketed toward the international space station Thursday as engineers on Earth pored over launch pictures that showed debris breaking off the fuel tank and striking the craft. Mission Control told the astronauts late Wednesday that the damage looked less extensive at first glance than what occurred on the last shuttle flight, but it will take days to sort through available data to reach a conclusion. The astronauts planned a Thursday afternoon inspection of their ship's thermal shielding, using a 100-foot laser-tipped boom.
