L4620

ST Microelectronics # L4620. An integrated circuit designed for the liquid level control in automotive applications. The liquid level is determined by the attenuation between transmitted and received signals across a sensor tip in the liquid. If the attenuation exceeds an internal threshold - sensor tip outside the liquid or liquid temperature higher than a determined value � a square-wave alarm output indicates an insufficient liquid condition. Internal circuits prevent spurious indications, and a latch keeps the alarm activated until the supply voltage is switched off. 8-pin dip package.

Physics promises wireless power

The tangle of cables and plugs needed to recharge today's electronic gadgets could soon be a thing of the past.

US researchers have outlined a relatively simple system that could deliver power to devices such as laptop computers or MP3 players without wires.

The concept exploits century-old physics and could work over distances of many metres, the researchers said.

Although the team has not built and tested a system, computer models and mathematics suggest it will work.

960E-1 Provides High Reliability and the Right Match for Mining

Rolling Meadows, IL, May 27, 2008 - Komatsu America Corp. is pleased to announce the introduction of the 960E-1 (960E) AC electric drive haul truck. The largest of Komatsu’s full line of mining trucks, the new model carries a 360 ton (327 tonnes) payload and weighs 1,270,000 lbs when fully loaded. The 960E balances payload, productivity and power, and is designed to be the right match for today’s mining needs. Just over 24’ tall,
the 960E uses modern frame design and manufacturing technology to ensure the quality of this new truck. With over 3 years of experience from coal fields to deep-pit copper mining, Komatsu has tested and proven the 960E to be ready for today’s mining needs.
