  • Patent number: 9778789
    Abstract: The rejection of undesired touch events on a touch surface is disclosed. A weighted meta-centroid of all touch events can be computed. In some examples, touches can be weighted inversely to their size and distance to the nearest neighboring touch. In some examples, touches can be weighted based on the size of their minor radii. A meta-ellipse can be fit to the weighted touch events. In some examples, the major axis of the meta-ellipse can be used to determine the orientation of a user's hand to reject undesired touches. In other examples, touches within the meta-ellipse can be rejected.

  • Patent number: 9690417
    Abstract: The dynamic adjusting of the conditions for identifying inputs as touching a touch-sensitive device is discloses. In some examples, in addition to using a signal density make threshold to identify an input patch as touching the surface, a signal density stability threshold can be used to identify the input patch as touching the surface. In some examples, a weighted average of peak signal density contributions from recent identified touches can be computed to dynamically adjust the make threshold for new input patches. In other examples, a new input patch identified as associated with the same path as an earlier touch can have its “make” threshold dynamically adjusted based on the earlier touch without computing a weighted average.

  • Patent number: 9659538
    Abstract: A system and method are disclosed to control the power consumption of column drivers in a display system. A video input signal is received which has an active video period and a vertical blanking period between frames. A timing controller transmits a first video frame to a column driver. The timing controller transmits a column driver disable command during a vertical blanking period. Prior to the subsequent active video period, the timing controller transmits a column driver enable command. The timing controller proceeds to transmit a second video frame to the column driver. In one embodiment, the timing controller determines whether to disable and enable the column driver based on a refresh rate, the refresh rate calculated by the timing controller from the video input signal.
