  • Patent number: 11681402
    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.

  • Publication number: 20230120125
    Abstract: A biometric sensor includes a body surface sensor and an e-field signal transmitter. The body surface sensor create a drive-sense signal at a first frequency based on one or more sensing parameters. When operably coupled to a body via one or more electrodes, the body surface sensor provides the drive-sense signal to the body and detects an effect on the drive-sense signal based on electrical characteristics of the body. The body surface sensor generate a data signal based on the detected effect, wherein the data signal represents the body’s electrical characteristics. The e-field signal transmitter generates an outbound signal reference at a second frequency based on the data signal and one or more transmit parameters. The e-field transmitter drives the outbound reference signal to the body, wherein the outbound reference signal is transmitted within at least a portion of the body as an outbound e-field signal at the second frequency.

  • Patent number: 11615047
    Abstract: A method for a low voltage drive circuit (LVDC) begins by receiving data from one or more other low voltage drive circuits (LVDCs) using a bus with varying loading at one or more frequencies and continues by sampling one or more data values of the data to produce a sampled digital data value, converting the sampled digital data value to a binary string and writing the binary string to a buffer. The method continues by writing one or more additional binary strings to the buffer to form a digital word, outputting the digital word to a digital converter circuit and formatting the digital word to create a formatted digital word. The method continues by writing the formatted digital word to a second buffer, writing additional formatted digital words to the second buffer to form a data packet and finally, outputting the data packet to a host device.
