Martek Power introduced an active power factor correction and harmonic attenuation module with 100-W output power, extending the power range offered by the PFC family to 100 W to 1,000 W. The PF100 is a COTS unit for military and aerospace applications and is
Energy efficiency standards have typically concentrated on two ends of the spectrum – full load efficiency and standby power. As a result, popular PWM buck regulators available today demonstrate high efficiency at full load (>80%) levels and incorporate standby circuitry to comply with the <1W and lower initiatives. Improved efficiency at all operating points is an important concern in the design of next generation “green” products.
Featuring interchangeable AC input clips, the PSAA20R adapter series from Phihong purportedly enables widespread compatibility. Available in single 12 V, 24 V, and 48 V outputs, the series allows for the use of a single part number. The adapters feature a maximum no-load power draw of 0.3 W and an average operating efficiency of greater than 81 percent.
Texas Instruments introduced a family of 16-bit analog-to-digital converters (ADCs) packaged in a leadless QFN measuring 2.0 mm x 1.5 mm x 0.4 mm – 70 percent smaller than the nearest competition, according to the company. The ADS1115 family performs conversions at
China will appeal a World Trade Organization ruling that ordered it to ease restrictions on imports of movies, music and books in a case brought by Washington, a Commerce Ministry spokesman said Monday. "We are actively preparing the documents to appeal," spokesman Yao Jian said at a news conference. Yao gave no details of the grounds for appeal but the government last week denied that it obstructed imports.
Scientists at IBM Research and the California Institute of Technology announced a scientific advancement that could be a major breakthrough in enabling the semiconductor industry to pack more power and speed into tiny computer chips, while making them more energy efficient and less expensive to manufacture.
Scientists have discovered a gene that helps a mother and daughter stay alert on about six hours sleep a night, two hours less than the rest of their family needs. It's believed to be a very rare mutation, not an excuse for the rest of us who stay up too late. But the finding, published in Friday's edition of the journal Science, offers a new lead to study how sleep affects health.
Since swine flu first emerged in April, it has sparked panic, vaccine production and now, a video game. In an effort to further raise awareness, Dutch researchers have created a game that challenges players to control a new pandemic. "It is actually what is happening now, what is happening in the real world," said Albert Osterhaus, head of virology at the Erasmus Medical Center, who designed "The Great Flu" game with colleagues.
The recent 2Q09 earnings results of the world’s top five handset vendors by volume showed a quarter-on-quarter growth of 12.1% in shipment numbers, led by LG, Samsung and Nokia. With channel inventory reduced to more normal levels, prospects for continued quarterly growth in 2H09 have improved.
This is quite a nice device. Available in capacities from 0.5 TB to 1.5 TB, the drive lets you maintain a real-time backup that can handle a fire (1,550° for ½ hour) and what happens after once the Fire Department gets there (immersion in 10 feet of fresh water or salt water for up to 3 days).
Extreme Engineering Solutions is shipping XCalibur1331, a conduction- or air-cooled, 6U VME solution featuring Freescale Semiconductor’s dual-core MPC8640D processor. The module is suitable for ruggedized systems requiring high bandwidth processing and low power consumption. The 8640D performs with
The e-publishing market may be following the same steps as its relatives in the music industry as Sony announced Wednesday that it will adopt the open ePub format for its Reader e-book readers. The move could signal the beginning of a new phase of e-publishing for consumers and businesses.
Dilas announced its high-power vertical diode laser stacked arrays available at 9xxnm (915 nm, 940 nm and 980 nm) wavelength with 150 W output power, continuous-wave (CW) per bar. The vertical stacks suit diode pump solid-state laser, materials processing, defense and medical applications requiring
Intended for use with Anritsu’s MG3700A Vector Signal Generator and MS269xA Signal Analyzer Series, the MX370110A LTE TDD IQproducer creates 3GPP LTE TDD waveform patterns. Its GUI shows the waveform format, including location, physical channels, and the power profile for the frame.
STEC, a solid-state drive (SSD) supplier to several large storage OEMs, is expanding its product lineup with enterprise-ready multi-level cell (MLC) drives with capacities up to 750 GB for a lower price than the single-level cell (SLC) versions currently in use for most enterprise applications.
