  • Patent number: 11448689
    Abstract: An electronic device, a signal validator, and a method for signal validation are provided. The electronic device includes a circuit board generating a plurality of signals and a signal validator. The signal validator records a current voltage level of each signal as a sequence code and records a time interval between the sequence code and a previous sequence code as a delay time corresponding to the sequence code when a voltage level of one of the plurality of signals changes. The signal validator sequentially determines whether the sequence code matches with a prearranged sequence code. When the sequence code matches with the prearranged sequence code, the signal validator determines whether each delay time corresponding to each sequence code exceeds a predetermined delay time. When the delay time is less than the predetermined delay time, the signal validator determines that the plurality of signals passes signal validation.

  • Patent number: 10866286
    Abstract: A connection detection system and a connection detection method are provided. The connection detection system includes a connector, an expansion dock and a signal transmitter. The connector has a first detecting pin and a second detecting pin. The second detecting pin receives a first signal or a second signal from the first detecting pin when the expansion dock is connected to the connector. The signal transmitter is coupled to the connector. The signal transmitter is configured to receive a detection signal through the second detecting pin and determine whether the connector is connected to the expansion dock according to the sensing signal. The signal transmitter provides the first signal to the first detecting pin when the connector is not connected to the expansion dock. The signal transmitter provides the second signal to the second detecting pin when the connector is connected to the expansion dock.
