Abstract: A multi-disc player testing apparatus for testing whether the multi-disc player satisfies the specific requirements is provided. The multi-disc player includes a carousel having multiple disc-accommodating areas and a disc-positioning sensor. The carousel defines a plurality of indicating slots for identifying each disc-accommodating area. The disc-positioning sensor scans the indicating slots to produce wave pulses in a form corresponding to the indicating slots. The multi-disc player includes a measuring module for receiving the wave pulses from the disc-positioning sensor, and measuring and comparing the number of the wave pulses and durations of each pulse with predetermined values to determine whether the multi-disc player satisfies the specific requirements.

Abstract: A rigid PCB assembly for an optical pickup includes a first rigid PCB, a second rigid PCB electrically connected to the laser diode, and a plurality of enameled wires electrically interconnecting the first PCB and the second rigid PCB.

Abstract: A data bus monitoring and controlling system is provided for monitoring and controlling a data bus. The data bus interconnects a controlling unit and a video/audio unit. The data bus monitoring and controlling system includes a reading module for reading information transmitted over the data bus, and a translating module for translating the information read from the data bus into readable information. Related data bus monitoring and controlling systems and methods are also provided.
