Abstract: A touch sensor device (TSD) includes TSD electrodes associated with a surface of the TSD. Also, an overlay that includes marker electrode(s) is also associated with a region of the surface of the TSD. The TSD also includes drive-sense circuits (DSCs) operably coupled to the plurality of TSD electrodes. A DSC is configured to provide a TSD electrode signal to a TSD electrode and simultaneously to sense a change of the TSD electrode signal based on a change of impedance of the TSD electrode caused by capacitive coupling between the TSD electrode and the marker electrode(s) of the overlay. Processing module(s) is configured to process a digital signal generated by the DSC and other digital signals generated by other DSCs determine the region of the surface of the TSD that is associated with the overlay and to adapt sensitivity of the TSD within that region.

Abstract: A touch screen display includes a display configured to display images in a display area. Touch sensitive row electrodes and touch sensitive column electrodes are integrated into the display and spaced apart to support a highest touch resolution. Also included are drive-sense circuits, a first switch network coupling a first group of drive-sense circuits to the touch sensitive row electrodes, and a second switch network coupling a second group of drive-sense circuits to the touch sensitive column electrodes. A switch controller is coupled to the first switch network and to the second switch network, and controls the first and second switch networks to control touch resolution of at least a portion of the display area. A processing is coupled to the switch controller and drive-sense circuits, and is configured to detect a proximate finger or stylus and, in response, transmit touch resolution change information to the switch controller.

Abstract: A method for execution by a touch screen computing device includes obtaining a touch signal associated with a row electrode of a touch screen display that is operable to render frames of data into visible images, where the touch screen display includes rows of electrodes oriented with columns of electrodes. The method further includes spatial filtering the touch signal in a first direction of the row electrode with respect to columns of the electrodes that form intersections with the row electrode to produce first direction touch signal data. The method further includes spatial filtering the touch signal in a second direction of the row electrode with respect to the intersections to produce second direction touch signal data. The method further includes combining the first and second direction touch signal data to produce a filtered touch signal. The method further includes processing the filtered touch signal to determine touch data.

Abstract: A low voltage drive circuit includes a transmit digital to analog circuit that converts transmit digital data into analog outbound data by: generating a DC component; generating a first oscillation at a first frequency; generating a second oscillation at the first frequency; and outputting the first oscillation or the second oscillation on a bit-by-bit basis in accordance with the transmit digital data to produce an oscillating component, wherein the DC component is combined with the oscillating component to produce the analog outbound data, and wherein the oscillating component and the DC component are combined to produce the analog outbound data. A drive sense circuit drives an analog transmit signal onto a bus, wherein the analog outbound data is represented within the analog transmit signal as variances in loading of the bus at the first frequency and wherein analog inbound data is represented within an analog receive signal as variances in loading of the bus at a second frequency.

Abstract: A voltage sensor includes a drive-sense circuit (DSC) and a reference load. The DSC is operably coupled to a point along a wire that is proximate to a battery terminal. The wire connects the battery terminal to a load. The DSC is configured to generate a signal based on a reference signal that is reference signal is based on an estimate of a voltage at the point along the wire. The DSC is also configured to generate an output signal that corresponds to a difference between the signal and the reference signal and to tune the reference signal until the signal compares favorably to the voltage at the point along the wire. The DSC also is configured to determine the voltage at the point along the wire based on the tuned reference signal. The reference load is operably coupled to the DSC and the point along a wire.

Abstract: A capacitive imaging glove includes electrodes implemented throughout the capacitive imaging glove and drive-sense circuits (DSCs) such that a DSC receives a reference signal generates a signal based thereon. The DSC provides the signal to a first electrode via a single line and simultaneously senses it. Note the signal is coupled from the first electrode to the second electrode via a gap therebetween. The DSC generates a digital signal representative of the electrical characteristic of the first electrode. Processing module(s), when enabled, is/are configured to execute operational instructions (e.g., stored in and/or retrieved from memory) to generate the reference signal, process the digital signal to determine the electrical characteristic of the first electrode, and process the electrical characteristic of the first electrode to determine a distance between the first electrode and the second electrode, and generate capacitive image data representative of a shape of the capacitive imaging glove.
