Strong-ARMing The Market

Embedded market applications have entered a new era thanks to extensive software support as well as the shrinking of borders between different processor technologies enabling the software ecosystem to expand to additional technology platforms. Consequently, the standard form factors at the board and module level must also be enhanced to fully realize the multiple interface options available with new processor platforms.

Factors to Consider When Selecting and Specifying LVDT Linear Position Sensors

Fitting the right type of linear position sensor to an application requires at least a working knowledge of the attributes of this electromechanical device. Starting with the basics, the LVDT (linear variable differential transformer) is a common type of linear position sensor widely used in electromechanical systems today. It consists of two basic elements: a stationary coil assembly and a movable core or armature. While most LVDTs are fundamentally AC-in/AC-out devices, some have electronics built-in to make them DC-in/DC-out devices. This gives rise to the terms “AC-LVDTs” and “DC-LVDTs”.

Transportation Category Winner (Winner of an HP Workstation)

Re-Thinking Automotive Tire Pressure Monitoring Systems Ivan Batinic ATPS, Inc., San Martin, CA The ATPS system is a new approach to implementing vehicular Tire Pressure Monitoring Systems (TPMS) that is more economical and ecological than existing systems. A passive, non-electronic sending unit (inside the tire) eliminates RF electronics, thermal compensation issues, raising of the RF noise-floor, and wasteful consumption of limited lithium resources for batteries. The TPMS is comprised of two fundamental components per wheel/tire assembly: an in-tire transducer, and an external, statically mounted chassis sensing component. Signal processing is performed by direct 2- or 3-wire sensor interfaces.
