ASTM E1571 - 11 outlines a procedure to standardize an instrument and to use the instrument to examine ferromagnetic wire rope products in which the magnetic flux and magnetic flux leakage methods are used. If properly applied, the magnetic flux method is capable of detecting the presence, location, and magnitude of metal loss from wear, broken wires, and corrosion, and the … [Read more...]
Space Telescope Explores New Energy Extremes
NASA’s Fermi Gamma-ray Space Telescope team plans to expand the telescope’s range into the uncharted electromagnetic range, after the telescope’s more than three years in space. The Large Area Telescope (LAT) “scans the sky every three hours, continually deepening its portrait of the sky in gamma rays, the most energetic form of light.” Most visible light is between two and … [Read more...]
Terahertz Transmitter Generates Highest Frequency Attained by Microelectronic Device
Scientists from the TU Darmstadt’s Institute for Microwave Technology and Photonics in Germany have developed a resonance tunnel diode (RTD) allegedly capable of generating “the highest frequency ever attained by a microelectronic device.” The device measures less than a square millimeter and scientists theorize that it may be produced using conventional semiconductor-device … [Read more...]

Dual Channel, Current Mode Step-Down Switching Regulator
Linear Technology’s H-grade version of the LT3641 is a dual channel, current mode step-down switching regulator with power-on reset and a watchdog timer. Its 4V to 42V input voltage range, with 55V transient capability, makes it ideal for load dump and cold crank conditions commonly found in automotive applications, which require constant output regulation even with input … [Read more...]
LightSquared Owner Pitches Network Directly to FCC Staffers
CEO of Harbinger Capital Partners, a private investment firm that owns LightSquared, a wireless broadband carrier, made a pitch to the FCC to approve commercial services. If approved, the company could put out 40,000 cell towers over the country. The FCC gave LightSquared a conditional waiver in late January of last year, telling them they needed to fix the interference … [Read more...]
