  • Touch scanning and wireless scanning in a portable computing device
    Patent number: 9891760
    Abstract: In an example implementation, a portable computing device may alternate between scanning for tactile input, such as a user's finger on a trackpad, and scanning for wireless input, such as a near field communication (NFC) signal. If tactile input is received, the portable computing device may stop scanning for wireless input while the portable computing device continues to receive the tactile input. When the portable computing device stops receiving the tactile input, the portable computing device may return to alternating between scanning for tactile input and scanning for wireless input. If wireless input is received, the portable computing device may stop scanning for tactile input while wirelessly communicating with the device from which the wireless input was received. When the portable computing device is finished wirelessly communicating with the device, the portable computing device may return to alternating between scanning for tactile input and scanning for wireless input.

  • Pressure-sensitive trackpad
    Patent number: 9250754
    Abstract: Trackpad apparatus and computing devices including trackpad apparatus are disclosed. In an example implementation, a trackpad apparatus includes a capacitive touch-sensing pattern disposed on a top surface of the trackpad apparatus and a capacitive pressure-sensing pattern disposed below the capacitive touch-sensing pattern. The trackpad apparatus also includes at least one controller. The at least one controller and the capacitive touch-sensing pattern are collectively configured to detect location-specific reductions in charge coupling in the capacitive touch-sensing pattern resulting from charge being shunted out of the capacitive touch-sensing pattern by one or more electrically conductive objects being placed in electrical contact with the top surface of the trackpad apparatus.

  • Touch sensor panel calibration
    Patent number: 8890854
    Abstract: A method for calibrating a touch sensor panel including a plurality of touch electrodes is provided. The method includes determining, for each of the plurality of touch electrodes, a contribution in terms of capacitance to a total capacitance of the touch sensor panel; and allocating a fraction of a fixed period of time for measuring a capacitance of each of the plurality of electrodes based on the electrode's contribution to the total capacitance.
