  • Signal inspection system for rotation control device and method thereof
    Patent number: 8102272
    Abstract: A signal inspection system for a rotation control device and a method thereof are disclosed. The signal inspection system comprises a signal capturing device, a determining module, a signal transforming device, and a processing module. A first signal and a second signal outputted by the rotation control device are captured by the signal capturing device, and the state of the first signal is determined by the determining module. Based on the state of the first signal, the machine language transformed from the first signal and the second signal are assembled by the processing module by use of a preset mode, and the assembled result is deciphered by the processing module for outputting a rotational direction of the rotation control device. Therefore, the accuracy of inspection result may be effectively improved up to one hundred percent.
