A method of verifying audio notifications generated within a vehicle includes generating an audio notification using an audio generation path that includes at least a controller, an audio notification generator and a speaker, wherein the controller generates an audio notification request utilized by the audio notification generator to generate an audio signal, and wherein the speaker converts the audio signal into the audio notification. The method further includes monitoring sounds within the vehicle using a microphone separate from the audio generation path and analyzing the monitored sounds using an audio analyzer, wherein the audio analyzer verifies whether the audio notification was generated. Feedback is provided to the audio generation path regarding whether generation of the audio notification was verified.

A lightweight radio/CD player for vehicular application is virtually 'fastenerless' and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting 'slide lock' and &#x201c;snap lock&#x201d; self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.

A compact disc player includes an optical pickup supported by a carriage and a microprocessor for controlling the movement of a coarse actuator and a fine actuator. The coarse actuator controls the movement of the carriage and maintains its position when power is interrupted to the coarse actuator. The fine actuator is disposed between the carriage and the pickup and provides fine movement for the pickup when power is supplied to the actuator. The fine actuator moves the pickup to a neutral position when power is interrupted. A resume function is provided that restores the position of the pickup after a power interruption to its position before the interruption. A value indicative of the position of the pickup relative to the carriage is stored in memory. When power is restored to the disc player, the value is read from memory. The disc control microprocessor directs incremental movements of the fine actuator until the position of the pickup corresponds to the position represented by the stored value.

A method is provided for altering a play list of a Random Access Player without interrupting the generation of output by the Player. The method includes initiating a reproduction mode that activates the Random Access Player, commencing the generating of output by the Random Access Player and receiving play list requests while the Random Access Player is generating the output, and processing the received play list requests while the Random Access Player is generating the output such that the play list is altered without interrupting the generation of output by the player.

An electronic theft deterrent system for deterring theft of an electronic device, such as a radio associated with a vehicle, that takes advantage of already existing device parameters, controls and displays associated with the device. When used as a theft deterrent system for the vehicle radio, a radio operator will first activate a frequency control switch in order to set an arbitrary frequency in the display of the radio. Next, a predetermined set of theft key radio control buttons are activated for a predetermined time in order to cause the arbitrary frequency that is displayed to be stored in a non-volatile memory. When the frequency is stored, the radio volume is impaired, but the total operation of the radio is not disabled. When the operator wishes to restore the radio to its normal operating condition, the operator will reset the arbitrary frequency, and reactivate the theft key control buttons. If the currently displayed frequency setting matches the stored frequency setting in the memory, the radio will be removed from the theft guarded condition, and the audio portion of the radio will be restored. If successive attempts to restore the radio to its normal operating conditions fail, an attempts counter will cause the radio to remain in its impaired state until an authorized service agent is able to restore the operation of the radio.

Varying the selection and play of tracks on a CD in non-sequential order includes a CD mechanism (12) with which a processor (16) communicates, a keyboard (17) having a shuffle play key (18) for user actuation, and a disc and track display (19). The processor (16) generates a shuffled selection offset (T.sub.n) from a deterministic function based upon a sequence number (S.sub.n) and a random seed (Seed). The deterministic function includes performance of plurality of binary operations which may include bit inversions, exclusive OR with an N-bit constant, N-bit rotations, bit swapping, one to one substitutions, and modulus additions and subtractions. The generated sequence plays all selections before any selection is repeated, allows the user to replay any past selection or skip to any unplayed selection while maintaining the same order, requires minimal memory and execution time, and is suitable for use with single-disc CD players and multi-disc CD changers.
