Apart from MPG, what’s a fair way to measure the efficiency of advanced technology vehicles?
X-Files fans, conspiracy theorists, and the tinfoil hat crowd were right all along! Sorta… In the 1950s, the US government really was building a flying saucer. But it didn’t involve little green men, human-alien hybrids, or David Duchovny; this isn’t what you’d call a "smoking gun."
The future of ultrasound technology, as interpreted by General Electric Co., looks a bit like a flip phone crossed with an iPod. GE CEO Jeff Immelt unveiled a handheld ultrasound machine at the Web 2.0 Summit in San Francisco Tuesday called the Vscan, saying it could become the "stethoscope of the 21st century."
Remember that story about a Bluetooth BlackBerry Watch accessory being in the works? In case you were doubting it, today we can say with certainty that it's happening, it's getting announced soon, and what you're looking at is an actual rendering of the real deal.
Purportedly able to go 3 to 5 meters longer than other passive options, a 10 meter SFP+ copper cable assembly (from W. L. Gore) is fully compliant with the SFF-8431 Revision 4.1 specification. Typical values for VMA loss are 3.95 dBe and a dWDP of 5.60 dBe.
Spring Design announced the first e-reader based on Google's Android operating system. Dubbed Alex, the device features full browser capabilities and a patented dual-screen interaction technology called Duet Navigator.
Crystek's CRBV55CW-1000-2000 RedBox VCO (Voltage Controlled Oscillator) operates from 1000 MHz to 2000 MHz with a control voltage range of 1.0 V to 20.0 V. This VCO features a typical phase noise of -100 dBc/Hz @ 10KHz offset. Output power is typically 5.5 dBm.
A family of brushless servo motors (from AMETEK) purportedly extends the service life of applications ranging from medical and industrial equipment to instrumentation and automation machinery, among others. These motors (AB23000, AB34000, and AB48000) in NEMA sizes 23 (2.25 in.), 34 (3.54 in.), and 56 (4.75 in.)
Researchers have devised a way to write memories onto the brains of flies, revealing which brain cells are involved in making bad memories. The researchers said that in flies just 12 brain cells were responsible for what is known as "associative learning". Associative memories are made when an animal learns to link a cue to a particular outcome.
Google Inc said more than 2 million businesses now use its online office software, and the Web search leader is going global on Monday with an advertising campaign to lure customers away from Microsoft Corp and IBM products.
The smell of manure hangs over Greeley as it has for half a century. These days it's more than just a potent reminder of the region's agricultural roots and the hundreds of thousands of cattle raised on the city's outskirts. The stench smells like an opportunity.
Non-contact displacement sensors from Capacitec perform to 1,000°C in manufacturing and testing applications. The HPC-150C-H sensor includes the following features: OD 9.5 mm size, range of 2.5 mm, and 0.25 micron resolution. The operating temperature is 400°C.
A family of Quadrature Clock Converter ICs from LSI Computer Systems (LSI/CSI) is designed to interface between incremental encoders and counting devices by converting the encoder quadrature outputs into directional up/down clocks or clock and direction signals.
With current up to 20 A, a line of sensorless drives from Koford Engineering is purportedly up to 99% efficient. The drives are for operation in 12 V to 48 V applications, and include a PWM frequency of 56k for cool motor operation. Open loop and digital closed loop versions are available
Russia has jumped on the CFL bandwagon, and decided to ban the incandescent bulb. As of January 1, 2014, the manufacture and sale of all incandescent bulbs will be prohibited in Russia.
