  • Patent number: 10936125
    Abstract: A method of operating a capacitive touch sensor, the capacitive touch sensor including an electrode, includes monitoring raw count data from the capacitive touch sensor and recording a first value of the raw count data when the raw count data exceeds a first threshold. The method also includes supplying a driven shield signal to the electrode after the raw count data exceeds the first threshold and recording a second value of the raw count data while supplying the driven shield signal to the electrode. The method further includes calculating a difference between the first value and the second value and registering a touch when the calculated difference between the first value and the second value is less than a second threshold.

  • Patent number: 10928881
    Abstract: An electronic device is disclosed. The electronic device can sense touch on its touch screen while in a sleep state in a manner that allows the electronic device to respond to certain touch inputs, while consuming less power due to touch sensing than while in an awake state. For example, sensing touch during the sleep state can allow the electronic device to wake (e.g., transition from the sleep state to the awake state) in response to detecting a certain touch input (e.g., a tap or other touch input) on its touch screen while in the sleep state. Various ways for the electronic device to sense touch during the sleep state are disclosed.
