Abstract
An event recorder (10) mounted in a vehicle (20) includes one or more wave pattern detectors (200) for detection and recognition of the presence of a predetermined wave produced external the vehicle (20) and for producing a trigger signal denoting predetermined wave presence. Event recorder (10) includes sensors, including image sensor (60), sound sensor (90), location sensor (95), and vehicle performance sensors, and a capture circuit for storing sensed data signals for the time period before, during and after the wave was detected. A playback circuit (13) presents the captured data. The detected wave is produced such as by the police or fire department, or by an emergency vehicle, and is typically produced for a purpose other than being detected by wave detector (200). Wave detector (200) may be illumination wave, e.g. infrared beam or flash, detector (230), a radar detector (214), a laser kB detector (224), a flashing light detector (240), or a siren detector (250).
