Available in versions rated from 1.5 MHz to 200 MHz, a family of programmable 3.3 Vin temperature-compensated crystal oscillators (TCXO) from Cardinal Components offer three outputs, CMOS, LVPECL, and LVDS.
Bureaucratic inefficiency and secrecy around government data have been hallmarks of our federal government since politicians wore powdered wigs. The country’s new chief information officer hopes to mutate governmental DNA in the direction of openness by releasing a massive amount of data about everything from swine flu to train schedules to the public, in a machine-readable, mashable way.
Offered in 61,800 rpm and 201,600 rpm windings of 1.9-in., high-speed motors from Koford Engineering include a vacuum compatible version, a 500-line optical encoder,
Some have predicted that crowdsourcing is the future of the marketing, advertising, and industrial design industries. The phenomenon, they argue, will accelerate creativity across a larger network.
Available in both in air- or conduction-cooled versions, the XMC-FPGA05F user-programmable FPGA XMC/PMC module incorporates the Xilinx Virtex-5 FPGA with four front-panel fiber-optic transceivers. (Alternative FPGAs, such as the LX155T, can be provided on request.) The transceivers are single- or multi-mode devices that support speeds including 2.0, 2.125, 2.5 and 3.125 Gbit/s.
Move over, silicon—it may be time to give the Valley a new name. Physicists at the Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have confirmed the existence of a type of material that could one day provide dramatically faster, more efficient computer chips.
Amazon has begun taking orders for its new Kindle DX e-reader, which is slated to begin shipping on Wednesday. The device has enough storage capacity to accommodate 3,500 books, the company said. The wireless device -- which sports a big 9.7-inch diagonal screen but is just one-third of an inch thick -- delivers instant access to magazines, newspapers and more than 285,000 books without users having to pay a monthly cellular bill. Amazon says e-books purchased for the device are delivered in less than 60 seconds over a built-in 3G wireless link that is widely available in all 50 states.
Available in 12-, 24-, and 48V output models, the PSA065 and PSA065M Series of 1U-high open-frame power supplies provide up to 65 W for applications such as telecom, data com, and industrial. Operating at more than 80% efficiency at maximum load, the 2 x 4-in. footprint supplies can tolerate temperatures from 0°C to +50°C and humidity from 5% to 95%.
Every time you swipe your credit card and wait for the transaction to be approved, sensitive data including your name and account number are ferried from store to bank through computer networks, each step a potential opening for hackers.
There’s no such thing as the perfect computer, and never has been. But in the personal computer’s long and varied history, some computers have been decidedly less perfect than others. Many early PCs shipped with major design flaws that either sunk platforms outright or considerably slowed down their adoption by the public.
Facebook's new personalised URLs feature has already come under fire from experts who believe it could be abused by cyber-squatters. The new service, which went live on Saturday, allows account holders to register more distinctive URLs for their profiles by choosing a specific username, which will then be displayed in the URL link to their profile.
Republicans on Saturday slammed a Democratic bill before the House that seeks to address climate change, arguing that it amounts to an energy tax on consumers. In the GOP's weekly radio and Internet address, Indiana Rep. Mike Pence said Congress should instead open the way for more domestic oil and natural gas production and ease regulatory barriers for building new nuclear power plants.
Provided in a thermally-enhanced 3.5 mm² QFN package, the SWIFT TPS54620 monolithic 1.6-MHz DC/DC converter is presented as the industry’s smallest single-chip, 6-A, 17-V step-down synchronous switcher with integrated FETs. Supporting input voltages from 4.5 V to 17 V, the device has power-good, enable, and tracking pins for sequencing.
Based on Continuous-Grain Silicon technology, LCDs with built-in memory capability in each pixel cut down on power consumption by a factor of 130 when compared to standard LCDs of equal size. Providing functionality similar to that provided by software video compression, each pixel in the display saves the image information so the image only has to be rewritten in the pixels where the content has changed.
Autocratic nations rarely feel the need to justify their actions. So China’s recent defense of its new internet filtering software was extraordinary. It also rings hollow. Starting July 1, the “Green Dam Youth Escort” software must be pre-installed on all computers sold within mainland China. The net-filtering software is aimed at protecting users from “harmful content.”
