Abstract: A system for controlling the playing of rented compact discs on an end-user's compact disc player. The end-user obtains a validation disc on which is stored a control program and an expiry date. When the validation disc is inserted into the user's player, the player downloads the control program into its memory and runs the program. This causes the expiry date to be read from the disc and stored in the player's memory. Discs to be played on the player have stored thereon a second control program which is downloaded into the player's memory when they are inserted into the player. This second control program causes the player to check whether or not the current date, as maintained by the player, is later than the stored expiry date. If the current date is later, playing of the disc is prevented, while if it is earlier, playing of the disc is allowed.

Abstract: A control circuit of a tray loading apparatus determines, according to a disc size and a tray moving direction, a time during which to control the motor at a constant speed. When the specified time has elapsed after the motor was started, the control circuit produces a pulse-width modulated output to slowly lower the motor speed, eliminating impact noise when the tray strikes a stopper. This motor deceleration time is measured. When the measured deceleration time disagrees with a preset or previously detected target deceleration time, the difference is either added to or subtracted from a constant-speed motor operation time and the resultant value is taken as the next target time for constant-speed motor operation. In this way, by changing the time during which the motor is driven at a constant speed, any variations in the tray moving speed as might occur from varying loads on the motor are absorbed to keep the motor deceleration time and decelerating speed unchanged, thus making the tray motion smooth.

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.
