Total Claims: 7
Claim 1
Independent Claim
183 words
Apparatus for recording audio information on a recorder means located in a vehicle and for playing back said audio information on a playback means in said vehicle comprising, means for producing a pulse each time said vehicle has traveled a selected distance during the recording of said audio information, means responsive to said pulses for recording said audio information over a pre-determined duration of time, means responsive to the termination of said predetermined duration of time for recording at least a selected audio frequency marking signal for a second predetermined duration of time, means responsive to the termination of said second duration of time for stopping said recording, means responsive to said pulses for playing back said recorded audio information on said playback means, and means for producing a signal beginning at a time after each of said pulses which is equal to said predetermined duration plus one-half of said second predetermined duration and which ends at a time after said each of said pulses equal to said predetermined duration plus said second predetermined duration for stopping the operation of said playback means.
