Abstract: A force detection system includes first and second sets of pressure sensors, memory, and a processing module. The first set of pressure sensors are in an insole of a shoe and the second set of pressure sensors are in an outsole of a shoe. The processing module receives first data regarding the first set of pressure sensors and generates a first digital representation of the first data. The processing module also receives second data regarding the second set of pressure sensors and generates a second digital representation of the second data. The processing module also writes the first and second digital representations to the memory.

Abstract: A touch-sensitive panel includes row electrodes, column electrodes, and drive-sense circuits coupled to the row electrodes and the column electrodes. The drive-sense circuits detect changes in impedances of the row and column electrodes. The touch-sensitive panel also includes analog-to-digital converters coupled to outputs of the drive-sense circuits, and a processing module coupled to the drive-sense circuits via the analog-to-digital converters. The processing module, the analog-to-digital converters, and the plurality of drive-sense circuits cooperate to sense an information signal capacitively coupled to the row and column electrodes, and to extract data from the information signal to identify a device that produced the information signal.

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.

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 are 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 is configured to control the first and second switch networks to control touch resolution of at least a portion of the display area between the highest touch resolution and lesser touch resolutions.

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 at least a portion 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 to determine characteristic(s) of the overlay that is associated with the at least a portion of the surface of the TSD.

Abstract: An electrical stimulation system includes a sheath that includes conductive points that are operative to facilitate electrical stimulation to a bodily portion of a user. Drive-sense circuits (DSCs) generate electrical stimulation signals based on reference signals and provide those electrical stimulation signals via electrodes to the conductive points of the sheath. The electrical stimulation signal is coupled into respective locations of the bodily portion of the user that are in proximity to or in contact with the conductive points of the sheath. In addition, the DSCs sense, via the conductive points of the sheath and via the electrodes, changes of the electrical stimulation signals based on coupling of them into the respective locations of the bodily portion of the user. The DSCs provide digital signals that are representative of the changes of the electrical stimulation signals to one or more processing modules that includes and/or is coupled to memory.

Abstract: A computing device includes signal generation circuitry and also includes a location on the computing device that is operative to couple a signal generated by the signal generation circuitry into a user. For example, the computing device includes signal generation circuitry that generates a signal that includes information corresponding to a user and/or an application that is operative within the computing device. The signal generation circuitry couples the signal into the user from a location on the computing device based on a bodily portion of the user being in contact with or within sufficient proximity to the location on the computing device that facilitates coupling of the signal into the user. Also, the signal may be coupled via the user to another computing device that includes a touchscreen display that is operative to detect and receive the signal.
