Abstract
A personal security device includes a motion sensor, such as a MEMS chip. In response to a characteristic motion pattern, especially acceleration of a car, the security device will trigger a consequence. The consequence might be an audible or visible alarm. Optionally the device may communicate with the engine to direct it to take some action, such as stopping or exploding air bags.
