Silicon Temp Sensors Measure by Degrees
January 25, 2008 6:05 am | by Jon Titus, Senior Technical Editor | Articles | CommentsPeople measure temperature more than any other physical characteristic. As a result, semiconductor vendors offer a large variety of silicon-based temperature sensors that usually operate in a range from -40°C to 125°C, although vendors sometimes tailor sensor spans for specific applications. Sensors used in PCs and servers, for example, may measure in a narrower range — about 75°C to 110°C. Depending on your application and budget, you can purchase inexpensive sensors with an accuracy of ±1°C to ±2°C.
Charger-Circuit Designs Fulfill Consumer Needs
January 25, 2008 6:00 am | by Jon Titus, Senior Technical Editor | Articles | CommentsLithium-ion batteries have taken the portable-electronics world by storm. Tony Armstrong, the power-products marketing manager at Linear Technology Corp. recently told me he bought his son a radio-controlled all-terrain vehicle. About half of the RC models and transmitters he examined came with lithium-ion or lithium-polymer batteries. Just two years ago, Armstrong found almost all models relied on nickel-cadmium or nickel-metal-hydride batteries.
Networked Digital Video Surveillance — What’s the Impact?
January 25, 2008 5:53 am | by Michael L Long – Product Line Manager, Industrial Video Applications | Articles | CommentsThe field of video surveillance has seen explosive growth in the last 3 years. The convergence of heightened security demand and innovative technology, in the acquisition, transport, analysis and storage of quality video has resulted in a massive deployment of cameras and systems in a number of venues. Major cities, transportation centers, highways, military installations, retail and business centers are all covered by the un-blinking gaze of millions of cameras. According to some reports, the UK alone has over 15 million security cameras.
Building Automotive GUIs “In a Flash”
January 25, 2008 5:51 am | Articles | CommentsAccording to Adobe Systems, over 300 million mobile devices have graphical user interfaces (GUIs) based on Adobe Flash technology – a number that may exceed a billion by 2010. Developers of in-car navigation and infotainment systems are also beginning to embrace Flash, for a simple reason: it can reduce the time to build a GUI by up to 50%. In the past, software teams had to translate their GUI prototypes into C, C++, or Java code, a labor-intensive process that can take many months. Now, teams can prototype their GUIs with high-level Flash tools and run those GUIs directly on embedded Flash players, without having to write graphics code.
