Abstract: Asymmetric scanning logic implements asymmetric panel scanning by scanning some rows on a touch panel more frequently than other rows. Note that although an entire row at a time may be driven, if only particular pixels in the row are of interest (e.g., included in any region of interest for focused asymmetric scanning), then circuitry may power down the receivers for the columns in which the pixels exist to save power. The asymmetric scanning logic facilitates focused attention to specific areas of interest on the touch panel, to compensate, for example, for high noise or low signal strength in those areas of interest.

Abstract: A touch sensitive pad with a plurality of touch sensitive elements and processing circuitry coupled to a communications interface and to the touch sensitive pad for scanning the plurality of touch sensitive elements to measure a plurality of touch sensitive element values. The plurality of touch sensitive element values is compared to a hovering finger threshold pattern. Upon a favorable comparison, a hovering finger condition is determined, and a position of the hovering finger in three-dimensions is detected with respect to the touch sensitive pad. The plurality of touch sensitive element values is compared to a touching finger threshold pattern. Upon a favorable comparison, a touching finger condition is determined, and a position of the touching finger is detected upon the touch sensitive pad.

Abstract: Control circuitry for a touch panel includes a touch panel interface, a memory comprising scanning logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the scanning logic is executed, to energize a first and a second row in the touch panel simultaneously, a first time; obtain a first signal measurement along a column intersecting the first and second rows; energize the first and the second row in the touch panel simultaneously, a second time; obtain a second signal measurement along the column; and determine a first pixel value and a second pixel value along the column from the first signal measurement and the second signal measurement.

Abstract: Provided a method of reducing impedance variations in an electrical circuit structured and arranged for placement on an integrated circuit (IC) substrate. The method includes forming sets of parallel connected resistors, each set corresponding to one of the impedance devices on the IC. Each set also includes two or more parallel resistor paths, each resistor path including two or more cascaded resistors and has a total impedance value substantially equal to the predetermined impedance value of its corresponding impedance device. Finally, the method includes configuring the sets of parallel resistor paths to form an interdigital structure across the substrate when the electrical circuit is placed on the IC.
