Electric motorbike teardown Teardown 9/26/2007 6 comments Vectrix designed its battery-powered VX1 motor scooter to go up against motorbikes from the likes of Honda and Yamaha. A teardown of the system shows how successful the company was at balancing performance with economy and low emissions.
POL converters deliver 30 A Product News 9/25/2007 Post a comment SynQor has expanded its NiQor family of non-isolated point of load (POL) converters with the introduction of the NQ15W50SGA30 device that delivers up to 30 A in the DOSA standard footprint and pinout.
Dual N-channel MOSFETs cut board space by 50% Product News 9/25/2007 Post a comment Fairchild Semiconductor's two latest dual N-channel PowerTrench MOSFETs are two highly integrated modules that are designed to reduce board space while providing the ability to achieve higher conversion efficiency in synchronous buck designs.
Bosch breaks ground for wafer fab News & Analysis 9/25/2007 1 comment Bosch has started construction works for its new wafer fab in Reutlingen, Germany. The production will be used predominantly in automotive electronics.
Micron, Dialog in new iPod nano Product News 9/19/2007 Post a comment For its latest version of the iPod nano, Apple apparently has exchanged most semiconductor suppliers, U.S. based market researcher group iSuppli has found. For instance, NXP chips are no longer used. However, with Dialog Semiconductor another European chip maker made it on Apple's shopping list.
Green issues challenge basestation power News & Analysis 9/19/2007 Post a comment Almost all mobile network operators now include in annual reports and on their websites worthy statements, usually in sections touting their corporate social responsibility, about what they are doing or plan to do to reduce the energy costs of running their basestations. The operators are beginning to take the issues almost as seriously as how to solve the more consumer-oriented problem associated with battery-life and power drain on handsets.
White LED driver integrates two LDOs Product News 9/13/2007 Post a comment Linear Technology has introduced an integrated white LED driver with dual LDO regulators for driving main and sub LED displays and supplying low-voltage system rails in portable electronic devices.
Your walls will be changing Design How-To 9/12/2007 1 comment It may not be obvious yet but digital entertainment may end up on your walls replacing the conventional picture hanging in your home. Driven by systems that enable taking digital pictures with downloading and displaying content easily and following the growth of digital and wireless phone cameras, the digital photo frame market is starting to expand rapidly. With continuing lower prices of LCD displays and the growing expectation of a visual media experience and you can see the potential.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
