Designed for use in daytime running lights, 1-W OSLON MX ECE and0.5-W SX ECE LEDs from OSRAM Opto Semiconductors provide from 70 to 95 lm and 40 to 60 lm respectively.
China broke ground on its fourth space center Monday, highlighting the country's soaring space ambitions six years after it sent its first man into orbit. The space port on the southern island province of Hainan incorporates a launch site and mission control center for slinging the country's massive new rockets into space carrying satellites and components for a future space station and deep space exploration.
The national stimulus package passed by Congress in February may have been too enthusiastic about spending money on one particular project: figuring out where broadband Internet access is available and how fast it is. The $787 billion stimulus bill championed by the Obama administration set aside up to $350 million to create a national broadband map that could guide policies aimed at expanding high-speed Internet access.
Europeans (like Americans) choose to buy ordinary light bulbs around 9 times out of 10 (European Commission and light industry data 2007-8). Banning what people want gives the supposed savings that are "good for them"—no point in banning what people don’t want! If new LED lights—or improved CFLs etc—are good, people will buy them—no need to ban ordinary light bulbs (little point).
Aitech Defense Systems has released a rugged 3U single-slot CompactPCI single board computer (SBC) that offers up to 8 GB of onboard SATA flash disk storage, making the system's PMC site available to add user specific I/O. The C800 combines the latest

The D10 Small Object Counter from Banner Engineering addresses applications including: pharmaceutical pill, tablet, and gel cap counting; agricultural seed counting; and process verification. With three primary features—Dynamic Event Stretcher (DES), Automatic Compensation, and Health Mode Alarm
Emerson Network added the DCH2 to its switching wall-mount power supply portfolio. Configured for portable and mobile equipment with low power requirements, the DCH2 is capable of delivering 6.5 V at a maximum of 2 W total power and offers a
Intended for rugged and mission-critical applications, a line of dual channel CompactFlash (CF) cards from WinSystems feature a DMA burst transfer rate of 66 MB/s to and from the CF card. Operating temperature is -40° to 85°C, sustained sequential Writes are 16 MB/s, and reads are 37 MB/s.
First photons, atoms and molecules. Now physicists want to create a quantum superposition of a virus, which will allow them to perform Schrodinger's Cat experiment for real.
With the aims of reducing energy wastage and improving distribution-network stability, regulatory authorities within the EU and US have been steadily introducing a series of measures that power-supply and equipment designers must consider. In the first instance, these measures specifically target no-load consumption and conversion efficiency for external power supplies of up to 250 W
Why the days of the dedicated music player have come and gone.
With an 11-ns Reverse Recovery Time and a Forward Voltage Drop of 2.1 V, the 8S2TH06I-M FRED Pt 600-V Hyperfast tandem rectifier from Vishay reduces losses in high-efficiency continuous current mode (CCM) power factor correction (PFC) applications by as much as 22 %.
Wireless power interoperability marked an important milestone with the 31 July 2009 release of 0.95 specifications of Qi, the Wireless Power Consortium’s “WPC” international standard in wireless power. This interoperability means that all Qi power receivers can be powered and charged with all Qi transmitters.
