  • 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.

  • Patent number: 9874972
    Abstract: The embodiments described herein provide devices and methods that facilitate improved input device resistance to the effects of errors that may be caused by the motion of detected objects on such input devices, and in particular, to the effect of blurring and/or fragmenting. The devices and methods provide improved resistance to the effects of such errors by decoupling the image generating interval from the reporting interval. Specifically, the devices and methods enable the determination of the reporting rate independently of the period over which images of sensor values are generated. The devices and methods enable independent determination of the reporting rate by facilitating the setting of a second period, where images of sensor values are generated over a first period and the reporting interval is determined to include at least the sum of the first period and the second period.
