  • Patent number: 8400426
    Abstract: Capacitive touchpad assemblies, toys including capacitive touchpad assemblies and integral card readers, and methods for detecting contact with a capacitive touch surface are provided. A capacitive touch surface may have a capacity that varies depending on whether it is being contacted by an object such as a human finger. A voltage of the capacitive touch surface may be altered during each of a predetermined number of recurring time intervals. The capacitance of the capacitive touch surface will determine the amount of time required to alter its voltage to a threshold voltage within each time interval. The sum amount of time required for the voltage of the capacitive touch surface to reach the threshold voltage in a predetermined number of time intervals may be used to determine whether the capacitive touch surface is being touched.
    Type: Grant
