METHOD AND APPARATUS FOR EMERGENCY NOTIFICATION

摘要

A portable apparatus (120) includes telecommunications circuitry (375) operable to communicate on a wireless carrier system, and a slave device (470) coupled to the telecommunications circuitry. The slave device (470) is operable to: receive a close-range, standard-protocol signal notification (440) from a master device (430) affixed to a vehicle, and trigger the telecommunications circuitry (375) to transmit to the wireless carrier system notification of an emergency event. The emergency event includes a change above a certain threshold magnitude of speed of the vehicle, a change above a certain threshold magnitude of acceleration of the vehicle, a change above a certain threshold magnitude of rate of acceleration of the vehicle, or deployment of an air bag.
