With a 5 mm x 7 mm footprint, the single-channel VoIP telephony IC integrates everything needed for a foreign exchange station and foreign exchange office interfaces, providing the SLIC and high-voltage line-feed together with a DSP, DC/DC controller and test load.
Suitable for use in distributed-power architectures, the A_S-1W Series of DC/DC Converters from Mornsun are rated to provide 1 W with an I/O isolation of 1,000 VDC. Standard models operate from 5 VDC, 12 VDC, 15 VDC, or 24 VDC and provide dual outputs of +/-5V, +/-9V, +/-12V, or +/-15VDC. Features include efficiency as high as 80% and a MTBF calculated to 3,500,000 hours.
Able to connect male and female connectors, a 7/8-in thread-locking, feed-through panel connector from Binder is available with 5 gold-plated contacts, rated at up to 8 A each.
New Mexico Governor Bill Richardson broke ground on Friday on construction of Spaceport America, the world's first facility built specifically for space-bound commercial customers and fee-paying passengers. The $198 million project, which is being funded by the New Mexico state government, is located on a remote high-desert range near the town of Truth or Consequences.
Across the country, it is hard to find an elected official who hasn't jumped on the green economy bandwagon. So many stump speeches marry the policy objectives of saving the environment and creating jobs. It starts at the top: President Barack Obama has promised to spend $150 billion over 10 years to create 5 million green-collar jobs. Like a human wave at a sporting event, Americans are cheering for the green economy to bring us out of our economic funk and solve global warming and foreign energy dependence, all at the same time.
Junfeng Geng at the University of Cambridge, in the U.K., and buddies have found a way to polymerize these microballs so that they line up into buckywires. The trick that Geng and co have found is a way to connect two buckyballs together using a molecule of 1,2,4-trimethylbenzene--a colorless aromatic hydrocarbon. Repeat that and you've got a way to connect any number of buckyballs.
Researchers from Korea claim to have produced the world's first purely white LED (light-emitting diode).Soo-Young Park, a professor of organic materials for photonics at the Department of Materials Science and Engineering at Seoul National University in Korea, led the group, which includes researchers from the University of Valencia in Spain.
Designed to operate with products such as the ADP5520 lighting management system and ADP5588 mobile I/O expander, the ADP8860 LED backlight driver from ANalog Devices has ambient light sensing, a programmable register set, and fading and dimming, which combine to reduce power dissipation by up to 50 percent. Accepting an input from 1.7 V to 3.3 V, the device has a parallel configuration enabling the control of up to seven LEDs – six at 30 mA max and one at 60 mA.
One city in Montana wants more than a job applicant's telephone number and address. Along with their job experience, city officials in Bozeman, Montana, are asking job seekers to provide passwords to social-network Web sites and other online groups to which they belong. Job applicants are being asked to sign a waiver that allows the city to not only check prior work experience, education and credit history, but also to check their social networks, blogs, and Internet chat rooms or forums.
Savvy consumers often go online for independent consumer reviews of products and services, scouring through comments from everyday Joes and Janes to help them find a gem or shun a lemon. What some fail to realize, though, is that such reviews can be tainted: Many bloggers have accepted perks such as free laptops, trips to Europe, $500 gift cards or even thousands of dollars for a 200-word post. Bloggers vary in how they disclose such freebies, if they do so at all. The practice has grown to the degree that the Federal Trade Commission is paying attention.
Light emitting diodes (LEDs) have been a hot topic in the TFT LCD market due to their rapid adoption in notebook PC displays and the high potential in LCD TV panels. In 2012, 34 billion LEDs will be used in TFT LCD backlights, in sizes ranging from 1” to more than 70”, up more than 300% from 8 billion in 2008
Accepting an input from 9 V to 75 V via a series resistor clamped with the device internal shunt regulator, the H-grade version of the LTC3803-3 current-mode flyback DC/DC controller from Linear Technology has an operating junction temperature from -40° C to 150° C.
Incorporating a white LED backlight and digital interface, the QVGA-resolution 3.5” diagonal OSD322427-6UFLWB LCD from OSD Displays has a maximum initial brightness of 800 cd/m2. Able to display 262k colors, the device interface is 24-bit digital RGB with VSYNC and HSYNC timing.
Rated at 2 A per contact, Harting's 3B and 3C DIN 4 16 12 product range of connectors for small PCBs contain 20 or 30 pins and have a 0.1-in. contact spacing.
Featuring a pre-assembled development board with an on-board OLED display for standalone testing, the Linx MDEV-GPS Master Development System contains everything needed to rapidly evaluate the company’s SG or SR Series GPS modules. The system can also be attached to a PC via USB using software that shows satellite positions, SNR, satellites in use, NMEA data, coordinates, and the module’s position on Google Maps.
