ABSTRACT:
A point-of-purchase advertising device generates a prerecorded audio message automatically whenever a person is nearby, and then resets itself automatically to prepare for the presence of another person. A motion detector generates a logic level signal whenever movement is sensed. This logic level signal causes a tape recorder to begin generating a prerecorded audio message. The audio output produced by the tape recorder is processed and converted to another logic level signal. This other logic level signal keeps the tape recorder on, and also disables the motion detector. The tape recorder turns off when the prerecorded message is over--since its processed audio output signal is all that keeps it on. The operation of the motion detector remains inhibited, however, until a preset period of time elapses after the prerecorded audio message is over. Inhibiting of the motion detector and the processing of the audio signal permit the advertising device to be used with a variety of different types of available conventional tape recorders/players.
