摘要： An e-pen includes e-pen sensor electrodes (including a first and a second e-pen sensor electrode) and drive-sense circuits (DSCs) (including a first DSC and a second DSC. The first DSC drives a first e-pen signal having a first frequency via a first single line coupling to the first e-pen sensor electrode and simultaneously senses, via the first single line, the first e-pen signal. Based on e-pen/touch sensor device interaction, the first e-pen signal is coupled into at least one touch sensor electrode of the touch sensor device. The first DSC process the first e-pen signal to generate a first digital signal representative of a first electrical characteristic of the first e-pen sensor electrode. Similarly, the second DSC drives a second e-pen signal having a second frequency via a second single line coupling to the second e-pen sensor electrode and simultaneously senses, via the second single line, the second e-pen signal.

摘要： A touch sensor device (TSD) includes a panel and drive-sense circuits (DSCs). The panel includes electrodes, and the DSCs are operably coupled to the electrodes. A DSC is operably coupled via a single line to an electrode and is configured to provide a signal via the single line to the electrode and simultaneously to sense the signal via the single line. The sensing of the signal includes detection of an electrical characteristic of the electrode and/or a change of the signal. The DSC is also configured to generate a digital signal representative of the electrical characteristic of the electrode and/or the change of the signal. The TSD also includes one or more processing modules operably coupled to the DSCs and configured to execute operational instructions to process first digital signals generated by a first subset of the DSCs that includes fewer than all of the DSCs in a prioritized manner.

摘要： A method includes transmitting, by a plurality of drive sense circuits of an interactive display device, a plurality of signals on a plurality of electrodes of the interactive display device. A writing passive device is identified based on a first plurality of changes detected in the electrical characteristics of the set of electrodes. Written user notion data is determined based on detecting movement of the writing passive device in relation to the interactive display device, and the written user notation data is displayed. An erasing passive device is identified based on a second plurality of changes detected in the electrical characteristics of the set of electrodes. Erased portions of the written user notation data is determined based on detecting movement of the erasing passive device in relation to the interactive display device, and the updated written user notation data is displayed based on no longer displaying the erased portions.

摘要： A method includes receiving a first signal from a first button circuit in a first location indicating possible interaction with a corresponding interactable element by a user, and receiving sensed signal data from a first sensor circuit indicating changes in electrical properties of an electrode of the first sensor circuit The method includes determining whether the sensed signal data indicates detection of a first frequency identifying the first location based on receiving the first signal indicating the possible interaction with the corresponding interactable element. When the sensed signal data indicates detection of the first frequency identifying the first location, performance of a functionality associated with the corresponding interactable element is facilitated.

摘要： A touchscreen display includes one or more display drivers coupled to an active matrix display and one or more touch controllers coupled to one or more touch sensor conductors. The one or more display drivers are coupled to the active matrix display via active matrix conductive components. When enabled, the one or more display drivers is configured to transmit a first signal to the active matrix display in accordance with display operation. A touch sensor conductor includes one or more segments of the active matrix conductive components. When enabled, a touch controller of the one or more touch controllers is configured to transmit a second signal via the touch sensor conductor in accordance with touchscreen operation that is performed concurrently with the display operation.

摘要： A capacitive touch screen display operates by: receiving a plurality of sensed signals indicating variations in mutual capacitance associated with a plurality of cross points formed by a plurality of electrodes; generating capacitance image data associated with the plurality of cross points that includes positive capacitance variation data corresponding to positive variations of the capacitance image data from a nominal value and negative capacitance variation data corresponding to negative variations of the capacitance image data from the nominal value; identifying a presence of water on the touch screen display based on the positive capacitance variation data, and the negative capacitance variation data; generating compensated capacitance image data to compensate for effects of the water on the touch screen display in the capacitance image data; and processing the compensated capacitance image data to determine a proximal condition of the touch screen display.
