Publication number: 20240133961Abstract: 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.Type: ApplicationFiled: December 7, 2023Publication date: April 25, 2024Applicant: SIGMASENSE, LLC.Inventors: Patrick Troy Gray, Michael Shawn Gray, Timothy W.

Publication number: 20230367416Abstract: 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.Type: ApplicationFiled: July 19, 2023Publication date: November 16, 2023Applicant: SIGMASENSE, LLC.Inventors: Daniel Keith Van Ostrand, Richard Stuart Seger, Jr., Shayne X.

Publication number: 20230305663Abstract: 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.Type: ApplicationFiled: May 8, 2023Publication date: September 28, 2023Applicant: SIGMASENSE, LLC.Inventors: Patrick Troy Gray, Gerald Dale Morrison, Daniel Keith Van Ostrand, Richard Stuart Seger, JR., Kevin Joseph Derichs, Shayne X.

Publication number: 20230233862Abstract: A pacemaker system includes a drive-sense circuit (DSC) operably coupled to a pacemaker lead. The DSC generates a pace signal including electrical impulses based on a reference signal. The DSC provides the pace signal via the pacemaker lead to an electrically responsive portion of a cardiac conductive system of a subject to facilitate cardiac operation of a cardiovascular system of the subject. The DSC senses, via the pacemaker lead, cardiac electrical activity of the cardiovascular system of the subject that is generated in response to the pace signal and electrically coupled into the pacemaker lead and generates a digital signal that is representative of the cardiac electrical activity of the cardiovascular system of the subject that is sensed via the pacemaker lead. The DSC provides digital information to one or more processing modules that includes and/or is coupled to memory and that provide the reference signal to the DSC.Type: ApplicationFiled: March 31, 2023Publication date: July 27, 2023Applicant: SIGMASENSE, LLC.Inventors: John Christopher Price, Shayne X.

Publication number: 20230124061Abstract: 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.Type: ApplicationFiled: December 5, 2022Publication date: April 20, 2023Applicant: SIGMASENSE, LLC.Inventors: Patrick Troy Gray, Gerald Dale Morrison, Daniel Keith Van Ostrand, Richard Stuart Seger, JR., Shayne X.
