The BSS further includes a first drive sense circuit operably coupled proximate to the battery to sense a first voltage. The BSS further includes a second drive sense circuit operably coupled proximate to the first load to sense a second voltage, where the second voltage and first voltage are different based on an impedance of the wired connection between the first point and the second point. The BSS further includes memory and processing modules to process the first and second voltages to determine operational status of the battery, wired connection, and loads.

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.

Abstract: 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.

Abstract: A method for execution by a Dynamic Random Access (DRAM) cell processing circuit in a read mode, includes receiving a pre-charge input and charging a bit-line operably coupled to a plurality of DRAM cells of a DRAM memory device, including a current DRAM cell, to a pre-charge voltage. The method continues by sensing a voltage change on the bit-line, where the sensing is based on a difference between a voltage stored on a DRAM cell capacitor of the current DRAM cell and the pre-charge voltage and generating a logic input for one of four voltage states for the current DRAM cell. The method then continues by supplying, supplying, based on the logic input, a corresponding logic voltage on the bit-line to refresh the voltage stored in the DRAM cell capacitor of the current DRAM cell.

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: A method includes generating, by a transmit digital to analog circuit of a low voltage drive circuit (LVDC), analog outbound data. The analog outbound data includes a direct current (DC) component and an oscillating component at a first frequency. The method further includes generating, by an analog transmit encryption signal generator of a transmit encrypt module of the LVDC, an analog transmit encryption signal having at least one frequency component, multiplying, by a mixer of the transmit encrypt module, the analog outbound data with the analog transmit encryption signal to produce an encrypted transmit signal having frequency components that differ from the first frequency. The method further includes generating, by a power source circuit of a drive-sense circuit of the LVDC, the encrypted analog outbound data as an analog transmit signal of a bus signal based on analog inbound data.
