The 600 V H-Series power factor correction (PFC) rectifiers from Qspeed Semiconductor purportedly has the highest switching efficiency of any silicon diode on the market. The H-Series products have a lower QRR temperature coefficient that purportedly minimizes switching losses at higher operating temperatures.
Geotest offers a user-configurable FPGA 3U PXI card that features 160 digital I/O signals for specific application needs. The GX3500 employs the Altera Cyclone III FPGA that supports clock rates up to 150 MHz and features over 55,000 logic elements. According to the company, the GX3500
Amazon's Kindle can read books aloud, but if you're blind it can be difficult to turn that function on without help. Now two universities say they will shun the device until Amazon changes the setup.
A newly discovered dinosaur species that roamed the Earth about 200 million years ago may help explain how the creatures evolved into the largest animals on land, scientists in South Africa said Wednesday. The Aardonyx celestae was a 23-foot- (7-meter-) long small-headed herbivore with a huge barrel of a chest, and the scientists told reporters it could prove to be a missing evolutionary link.
Capable of delivering up to 200 mA continuous load current at each output, the dual LDO AS1374 (from austriamicrosystems) is intended for portable battery powered devices. These include RF, cell-phone cameras, wireless base stations, and PA bias supplies. The LDO operates from a 2 V to 5.5 V supply
A group of engineers from National Instruments, called Waterloo Labs, created an iPhone app that can drive a car. In part 2, they give a detailed explanation of how they designed and implemented our control system. This video provides more details about the motor assembly, the wireless communication...
A group of engineers from National Instruments, called Waterloo Labs, created an iPhone app that can drive a car. See below. Part 1 includes an overview of how NI turned an Oldsmobile Delta 88' into a remote control car in just a few weeks. They built their control systems using a few motors, potentiometers, a CompactRIO embedded controller, and LabVIEW.
Providing a simple way to connect I²C to USB, the IOW24-DG USB to I²C dongle from Saelig operates at 100 kHz and allows a throughput of up to 750 bytes/s. 5-V and 3.3-V outputs are also available to power small external circuits...
Washington DC, USA and Cheltenham, UK – Artisan Software Tools, a leading supplier of industrial-grade, collaborative modeling tools for complex, mission and safety-critical embedded systems and software, has acquired Extessy, a supplier of development tools and services...
Four years after its first solar sail ended up in the ocean instead of orbit, The Planetary Society announced Monday that by the end of 2010 it will try again to launch a spacecraft that will be propelled by the subtle pressure of sunlight.
British scientists begin a new study on Tuesday to consider how human DNA is used in animal experiments and to determine what the boundaries of such controversial science might be. Though experts have been swapping human and animal DNA for years...
Big things often come in small packages. That's certainly the case with the potential created by recent successes in hydrogen research at Idaho National Laboratory. Steve Herring, technical director of the High Temperature Electrolysis Nuclear Hydrogen Initiative, has a solid-oxide electrolysis cell no larger than a standard CD. However, the two electrodes and electrolyte that make up the cell are almost eight times thinner than a CD at a mere 150 microns.
Lightning strike tests of a helicopter at Eurocopter's Donauwörth facility have verified the accuracy of finite element analysis techniques for characterizing the electromagnetic behavior of complete and custom-cabled modern aircraft structures constructed using advanced composite materials.
With the technology industry looking on, the Supreme Court on Monday will explore what types of inventions should be eligible for a patent in a pivotal case that could undermine such legal protections for software.
DisplaySearch indicated in its latest Monthly Large Format Commercial Displays Sell Through Report that large (26”+), non-consumer LCDs had their highest sell-through quarter ever in US commercial distribution in Q3’09, with shipments up 41% Q/Q and 19% Y/Y. In addition, September sell-through was up 49% from shipments in August, and was the largest sell-through month on record for LCD commercial-use displays.
