Auto Crash and Rollover Sensing requires higher bandwidth due to the higher da/dt jerk content of crash signals. ESC requires < 1.0 g because lower amplitude and slower da/dt and less rapidly chaning forces are involved.
The inherent reliability of these thermal accelerometer due to the absence of moving parts makes them ideal for some designs. Not sure how much these devices will be limited as specialty components or if additional research will enable them to penetrate additional applications. Seems to be part of the challenge going forward.
Yes, I remember that the Japanese flying machine was a great story. The size of the accelerometer makes for a wide range of applications. Years ago, Deisgn News flew me out to Research Triangle to do a video interview with Motorola when they included an accelerometer in a phone. It was used for games and to shake the song list to the next song.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
With strong marketplace demand for qualified engineers across the board that currently outstrips the available supply, there may never be a better time for engineers and project managers to advance their careers and salaries. Whether those moves are successful in the short-term and long-term is likely to depend on how the transition from one job to the next is handled.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
