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 drive-sense circuit module (DSC) includes at least one regulated source circuit coupled to a load, and to a loop correction circuit. The regulated source circuit generates a power signal, which has a regulated characteristic and a controlled characteristic. At least one reference circuit applies a reference signal to the loop correction circuit that establishes a reference value of the controlled characteristic. The loop correction circuit senses an effect of one or more load characteristics on a sensed value of the controlled characteristic of the power signal, and generates a comparison signal based on the sensed value and the reference value of the controlled characteristic. A regulation signal is generated based on the comparison signal, and used to regulate the regulated characteristic of the power signal. A control module, including a processor, controls the regulated source circuit and the loop correction circuit to iterate through a plurality of different regulated characteristics and different controlled characteristics.

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 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 data formatting module of a low voltage drive circuit (LVDC) includes a sample and hold circuit, an interpreter, a first buffer, a digital to digital converter circuit, and a data packeting circuit. The sample and hold circuit is operable to sample and hold an n-bit digital value of filtered digital data to produce an n-bit sampled digital data value. The interpreter is operable to convert the n-bit sampled digital data value into interpreted n-bit sampled digital data. The interpreter is operable to write the interpreted n-bit sampled digital data into the first buffer in accordance with a write clock until a digital word is formed. The digital to digital converter circuit is operable to format the digital word to produce a formatted digital word. The data packeting circuit is operable to generate a data packet from the formatted digital word and output the data packet as received digital data.
