Abstract:
In combination:a vehicle; and an event recorder mounted to said vehicle comprising: a wave pattern detector for detection and recognition of the presence of a predetermined wave produced external said vehicle, and for producing a trigger signal denoting predetermined wave presence; a plurality of sensors, including: first image sensing means for sensing optical images and for producing a first image sensor signal representing the sensed images; and sound sensing means for sensing sound and for producing a sound sensor signal representing the received sound; a persistent memory device; and a capture circuit connected to said sensors for receiving and capturing the sensor signals therefrom, connected to said wave pattern detector for receiving a trigger signal therefrom and for terminating capture of the sensor signals within a predetermined time period upon receipt of a trigger signal therefrom, and connected to said persistent memory device for loading the captured sensor signals therein.
