Let's start with a tough question: What is the difference between TPMS system and PKE system? Nothing! A TPMS system is placed inside the wheel and composed of a sensing device that measures temperature and pressure. When appropriate, for example before starting the engine, the car requests a measurement through a wireless link. If a pressure default occurs in one of the wheels, the car warns the driver through a signal on the dashboard. In PKE applications, the user carries a key fob device which contains an encoded identifier (ID). When the driver enters their car, the car requests the key fob ID through the wireless link. If the ID matches the ID stored by the car,
Here is a collection of articles on the subject of Solid-State lighting.
Just as they have played a key role in advancing industries such as PCs, cellular telecommunications and automotive, digital signal processors (DSPs) are playing an increasingly important role in advancing medical imaging to provide faster, more accurate diagnoses and treatment.
With over 8,000 attendees, this year’s Embedded Systems Conference (ESC) was a pleasant surprise to an industry expecting a low turnout. Held in San Jose from March 30 to April 2, the event had a nice assortment of new tech and devices. Here is our second portion of our two-part coverage of the event.
There's an old saying, "you can even get used to hanging, if you hang long enough". This industry has been on a rollercoaster for over a decade, between the Dot-Bomb, the Telecom collapse, the Internet, the housing bubble, the bank crisis, and disruptive technologies, we've been beaten about like a Pinata on Cinco de Mayo.
There are always things to consider when prototyping a design. Here are a few essays on the subject to aid you in your efforts.
Virtualized systems development is a development methodology where the actual hardware of a system is augmented by a virtual platform, a simulation model of the hardware running on a workstation or PC. The virtual platform can run the same binary software as the physical hardware, fast enough to be used as alternative to physical hardware for software development.
The SMB339 Series programmable battery charger from Summit Microelectronics has features such as integrates additional features, such as "instant-on", even with a dead battery, and real-time charge current monitoring.
Designed to work in conjunction with other devices on the board that require a reference clock, such as PHYs, switches, ASICs, and network processors, the 843N156-125 FemtoClock from IDT generates a 125-MHz single-ended output and a 156.25-MHz LVPECL output from a single 25-MHz crystal.
Clearwire says it remains on track to launch its Clear-branded WiMAX 4G service in Atlanta next month, with Las Vegas slated for a late summer launch and Chicago, Philadelphia and Dallas/Fort Worth scheduled for rollouts later in the year.
Samsung Electronics, the world's top TV brand, aims to outperform the overall flat-panel television market's growth this year, thanks in part to its newly launched LED models, a senior official said. "2009 won't be an easy year but we plan to maintain market leadership with new products such as LED TV," said Sue Shim, senior vice president in charge of sales and marketing at Samsung's Visual Display division.
Carnegie Science Center and Carnegie Mellon University announced the 2010 class of inductees into the Robot Hall of Fame at a press preview of roboworld, the Science Center’s new robotics exhibition opening June 13 and the permanent home for the Robot Hall of Fame.
Hynix Semiconductor, LG Electronics, Samsung Electronics , and Silicon Image today announced the formation of an industry consortium that promotes Serial Port Memory Technology (SPMT) for broad market adoption as an industry standard.
Able to generate clocks from 10 KHz to 230 MHz, the FD7 Series multiple frequency clock generator provides up to seven independent CMOS outputs in a single 5 x 7-mm LCC ceramic package.
