Abstract: A current reference operative drive-sense circuit (DSC) includes a current source operably coupled to a load and a voltage-mode analog to digital converter (ADC). When enabled, the current source is configured to drive a sinusoidal current reference signal to the load thereby generating a load voltage that is based on the sinusoidal current reference signal and an impedance of the load. The voltage-mode ADC is operably coupled the load and to the current source. When enabled, the voltage-mode ADC configured to perform digital sampling of the load voltage and to generate a digital signal that is representative of the load voltage. In some implementations, one or more processing modules is configured to execute operational instructions to process the digital signal that is representative of the load voltage in accordance with determining impedance of the load and/or change of impedance of the load.

Abstract: A battery characterization system includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s) operably coupled to the DSC and the memory. Based on a reference signal, the DSC generates a charge signal, which includes an AC (alternating current) component, and provides the charge signal to a terminal of a battery via a single line and simultaneously to senses the charge signal via the single line to detect an electrical characteristic of the battery based on a response of the battery. The DSC generates a digital signal representative of the electrical characteristic of the battery. The processing module(s), based on the operational instructions, generate the reference signal to include a frequency sweep of the AC component of the charge signal (e.g., different frequencies at different times or multiple frequencies simultaneously) and processes the digital signal to characterize the battery across the different respective frequencies and generate spectrum analysis (SA) information of the battery.

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.

Abstract: A power supply signal conditioning system includes a power supply, one or more loads, and a drive-sense circuit (DSC). The power supply is operably coupled to one or more loads. When enabled, the power supply configured to output a power supply signal having a DC (direct current) voltage component and a ripple voltage component that is based on conversion of an AC (alternating current) signal in accordance with generating the power supply signal. The DSC is operably coupled to the power supply. When enabled, the DSC is configured simultaneously to sense the power supply signal and, based on sensing of the power supply signal, adaptively to process the power supply signal in accordance with reducing or eliminating the ripple voltage component of the power supply signal to generate a conditioned power supply signal to service the one or more loads.

Abstract: A rotating equipment system with in-line drive-sense circuit (DSC) electric power signal processing includes rotating equipment, in-line drive-sense circuits (DSCs), and one or more processing modules. The in-line DSCs receive input electrical power signals and generate motor drive signals for the rotating equipment. An in-line DSC receives an input electrical power signal, processes it to generate and output a motor drive signal to the rotating equipment via a single line and simultaneously senses the motor drive signal via the single line. Based on the sensing of the motor drive signal via the single line, the in-line DSC provides a digital signal to the one or more processing modules that receive and process the digital signal to determine information regarding one or more operational conditions of the rotating equipment, and based thereon, selectively facilitate one or more adaptation operations on the motor drive signal via the in-line DSC.

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.
