  • Driven shield for shaping an electric field of a touch sensor
    Patent number: 10146361
    Abstract: In one embodiment, a method comprises generating, by a control unit, a first drive signal and a second drive signal. The method further includes emitting, by a touch sensor, a first electric field that extends in a plurality of directions in response to reception of the first drive signal. The method also includes attenuating, by a conductive shield, a portion of the first electric field that extends from the touch sensor towards the conductive shield by generating a second electric field in response to reception of the second drive signal.
    Type: Grant

  • Method for Rejecting a Touch-Swipe Gesture as an Invalid Touch
    Publication number: 20140347312
    Abstract: In one embodiment, a method for rejecting a touch-swipe gesture as an invalid touch includes receiving a signal indicating a touch-swipe gesture on a display coupled to a touch sensor operable to detect touch input, the touch sensor having a first capacitive node and a second capacitive node surrounding at least a portion of the first capacitive node. The method also includes detecting that the touch-swipe gesture activated the second capacitive node and, in response to the touch-swipe gesture activating the second capacitive node, rejecting the touch-swipe gesture as an invalid touch.

  • Conductive shield for shaping an electric field of a conductive wire
    Patent number: 8786356
    Abstract: In one embodiment, a method comprises generating, by a control unit, a first drive signal and a second drive signal. The method further comprises emitting, by a conductive wire coupled to a capacitive touch sensor, a first electric field that extends in a plurality of directions in response to reception of the first drive signal. The method further comprises shaping, by a conductive shield that surrounds the conductive wire, at least a portion of the first electric field that extends from the capacitive touch sensor towards the conductive shield by generating a second electric field in response to reception of the second drive signal.
