There are always things to consider when prototyping a design. Here are a few essays on the subject to aid you in your efforts.
Low-power, high-efficiency electronic memory could be the long-term result of collaborative research led by Cornell materials scientist Darrell Schlom. The research, to be published April 17 in the journal Science (Vol. 324 No. 5925), involves taking a well-known oxide, strontium titanate, and depositing it on silicon in such a way that the silicon squeezes it into a special state called ferroelectric -- a result that could prove key to next-generation memory devices.
With hardened-steel helical and spur gearing in ratios from 108:1 to 266:1, the VWDIR104 AC gearmotor family offers fixed output speeds from 15 to 6 RPM with continuous torque ratings from 340 to 500 in-lbs (38.4 to 56.5 N-m). Features include built-in face mounting compatible with Genesis mounts and an overhung load capability up to 400 lbs. (181.8 kg.).
Provided in a 19" rackmount server chassis, the RTS 2701 Recording and Playback System from Pentek includes a Dual-channel multiband transceiver. The system is well suited for digitizing analog signals from a communications system or a radar system and delivering that data to high-speed disk arrays at sustained data rates as high as 500 MB/second.
President Barack Obama on Monday will propose changing provisions in the tax code that he says encourage U.S. companies to move jobs overseas, as part of a broader package aimed at saving $210 billion over 10 years. U.S. officials said that in an announcement planned for 11:05 a.m. EDT, Obama will seek to follow through on a campaign promise to change the tax treatment of American firms with overseas operations.
Facebook has brought in some soldiers to fight the war against malware and phishing scams on the social-networking site. After two different malware attacks this week, Facebook announced it would begin using San Francisco-based MarkMonitor's antifraud services as an additional layer of protection against attacks.
Designed to provide mission-critical wireless communications, the Proxicast’s new Cell-PAK 3G + Wi-Fi HotSpot in a box is a wireless "grab & go" solution that provides mobile wide-area cellular Internet connectivity (WWAN) and local 802.11 a/b/g Wi-Fi access (WLAN) in an easy-to-deploy portable form-factor. The Cell-Pak features Proxicast’s commercial-grade LAN-Cell 2 mobile 3G cellular router.
President Barack Obama's commitment to take on climate change and put science over politics is about to be tested as his administration faces a politically sensitive question about the widespread use of ethanol: Does it help or hurt the fight against global warming?
Designated the 5802 Series, a 0.4-mm-pitch board-to-board connectors from AVX is presented as the smallest available, with a 0.8-mm stacking height and 3.2-mm width, including tails.
Available in a variety of packaging including TO-220, D2PAK, TO-262, and 7-lead D2PAK, logic-level gate-drive trench HEXFET power MOSFETs from International Rectifier have a package current rating of up to 195 A.
Researchers at MIT have developed a new system that may provide a cheaper and more efficient way to track motion. The system, called Second Skin, could be a cheaper alternative for creating special effects for movies.
Conventional wisdom says that “early adopters” eventually bring new technologies into the mainstream. Thus, the effort to promote solid state lighting (SSL) has ample historical precedence. Back in the late 70’s, 80’s, and 90’s an epic battle was waged between Video Home System (VHS) and Betamax (Beta). One can draw lessons from the eponymous “videotape format war”—specifically, why technologies catch on (while others fade away)
Designed for applications with high-power inductive loads, Allegro’s A4940 full-bridge MOSFET pre-driver IC incorporates fault diagnostics and reporting functionality. With an operating voltage from 5.5 V to 50.0 V, the 24-pin TSSOP-packaged device has a bootstrap charge management system that ensures the bootstrap capacitor is always sufficiently charged to supply the high-side gate drive circuit.
Motorola Inc. defeated low expectations Thursday, posting a smaller first-quarter loss than Wall Street had expected and regaining its position as the world's fourth-largest maker of cell phones. Investors were largely unimpressed, and analysts pointed to deterioration in the Motorola units that have been propping up the dismally performing cell phone operations.
Electronic health records need a nudge from the government if the technology is to become widespread, the nation's new health information technology czar said on Thursday. "It is clear that this field has not advanced (enough) when left exclusively to the private sector so there is a public role," said Dr. David Blumenthal, head of the Department of Health and Human Services' Office of the National Coordinator for Health Information Technology.
