Audio-visual recording apparatus for vehicles
First Claim
1. Apparatus for obtaining and recording visual data relating to a vehicle having an engine, the engine having a status of either operating or not operating;
- a battery for supplying electrical energy to the engine;
a selectively controllable ignition switch, the ignition switch having a closed position permitting the flow of electrical energy from the battery to the engine, and an open position preventing the flow of electrical energy from the battery to the engine;
said apparatus comprising;
shutoff means for changing the status of the engine from operating to not operating, independently of the ignition switch position, independently of any signal generated externally to the vehicle and without the necessity of any operator intervention;
activation means responsive to said status of the engine for activating the apparatus when the engine is in its operating status, and for deactivating the apparatus when the ignition switch is closed and the shutoff means changes the status of the engine from operating to not operating;
visual data gathering means, responsive to the activation means, for gathering the visual data; and
recording means, at the vehicle and responsive to the visual data gathering means, for continuously recording and sequentially over-writing the visual data.

Abstract
A system for acquiring and recording audio, visual and other information, relating to the condition or environment of a motor vehicle, and for storing the information at the vehicle for playback and analysis. The system is activated by the “on” status of the engine, or by the “alert” status of an alarm system if present. A camera may be used to acquire visual data, and a microphone may be used to acquire audio data. Other types of data—e.g., speed; date and time; or confirmation of braking—can likewise be acquired by conventional sensing devices. Acquired visual, audio and other data may be recorded in a solid-state device, such as a flash card or F-RAM. Data is continuously and sequentially over-written until the system is deactivated. Playback may be accomplished through a computer or television set.

14. Apparatus for obtaining and recording visual data relating to a vehicle having an engine with a vacuum line and a battery transmitting electrical energy to the engine when the electrical circuit between the battery and the engine is closed, the engine having a status of either operating or not operating, said apparatus comprising:
-
shutoff means for changing the status of the engine from operating to not operating, independently of any signal generated externally to the vehicle and without the necessity of any operator intervention;
activation means, responsive to said status of the engine, for activating and deactivating the apparatus;
visual data gathering means, responsive to the activation means, for gathering the visual data;
recording means, at the vehicle and responsive to the visual data gathering means, for continuously recording and sequentially over-writing the visual data; and
a switch electrically intervening between the battery and the activation means, the switch permitting transmission of electrical power from the battery to the activation means only when the switch is closed, the switch being closed only when a vacuum is present in the car engine vacuum line, the activation means being responsive to said status of the engine by electrical power passing through the switch, closure of said switch occurring in response to the not operating status of the engine and without the necessity of operator intervention or any externally-generated signal.
