Apparatus for magnetic recording of casual events relating to movable means
First Claim
1. An apparatus for video surveillance of the environment about a vehicle, said apparatus comprising:
- (a) scanning means, mountable on said vehicle, for scanning said environment and converting images of said environment to electric signals;
(b) storage means for receiving and storing said signals, said storage means having a specific storage capacity and being adapted to update stored signals when said storage capacity is full, whereby said updating is effected by superposition of newly received signals upon the oldest stored signals to thereby erase said oldest stored signals; and
(c) Sensor means, mountable on said vehicle, for sensing specified changes in travel of said vehicle and, in response to said sensed changes, automatically preventing said updating of said storage means to provide fixed storage signals.

Abstract
The invention consists of an apparatus for recording accidental events relating to movable devices such as automotive vehicles, which events can be sensed by optical observation, and comprises: detecting means for receiving the images of the event and transforming them into electric signals; a signal storing circuit comprising one or more analog memories, wherein the recording of successive events is carried out by automatically erasing the oldest image; and sensor means for assuring automatic interruption of the incoming signal flow from the image detecting means to the memories to achieve the automatic nonerasable storage of images corresponding to a predetermined period immediately preceding and contemporary to the accidental event.
