  • Apparatus and method for determining the validity of an infrared signal of a remote-control device cross-reference to related applications
    Patent number: 12272233
    Abstract: Apparatus and method for determining the validity of an infrared signal of a remote-control device. An infrared signal comprising pulses representing data corresponding to a function of a controllable target device is received from a remote-control device. The received infrared signal is passed through a capacitor of the apparatus such that, for each pulse of the infrared signal, the capacitor is charged and subsequently discharged. The capacitor discharge time associated with each pulse of the infrared signal is measured by a processor of the apparatus to establish a discharge sequence. The processor of the apparatus compares the established discharge sequence with a plurality of pre-determined valid discharge patterns and determine the validity of the received infrared signal based on the outcome of the comparison of the established discharge sequence with the plurality of pre-determined discharge patterns.
