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.

A device operative to transfer power and communicate wirelessly includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s). The DSC generates a drive signal based on a reference signal and provides the drive signal to a first coil via a single line and via a resonating capacitor, and simultaneously senses the drive signal via the single line, to facilitate electromagnetic coupling to a second coil to transfer power wirelessly to another device. The DSC also detects electrical characteristic(s) of the drive signal including whether a communication signal is transmitted from another device and generates a digital signal representative thereof. The processing module(s) generates the reference signal, processes the digital signal including to determine whether the communication signal is transmitted from the other device to the device and appropriately processes the digital signal to interpret control information of the communication signal to adapt the reference signal.

An electrical stimulation system includes a sheath that includes conductive points that are operative to facilitate electrical stimulation to a bodily portion of a user. Drive-sense circuits (DSCs) generate electrical stimulation signals based on reference signals and provide those electrical stimulation signals via electrodes to the conductive points of the sheath. The electrical stimulation signal is coupled into respective locations of the bodily portion of the user that are in proximity to or in contact with the conductive points of the sheath. In addition, the DSCs sense, via the conductive points of the sheath and via the electrodes, changes of the electrical stimulation signals based on coupling of them into the respective locations of the bodily portion of the user. The DSCs provide digital signals that are representative of the changes of the electrical stimulation signals to one or more processing modules that includes and/or is coupled to memory.

A method for execution by a touch screen computing device includes obtaining a touch signal associated with a row electrode of a touch screen display that is operable to render frames of data into visible images, where the touch screen display includes rows of electrodes oriented with columns of electrodes. The method further includes spatial filtering the touch signal in a first direction of the row electrode with respect to columns of the electrodes that form intersections with the row electrode to produce first direction touch signal data. The method further includes spatial filtering the touch signal in a second direction of the row electrode with respect to the intersections to produce second direction touch signal data. The method further includes combining the first and second direction touch signal data to produce a filtered touch signal. The method further includes processing the filtered touch signal to determine touch data.

A noise canceling audio in/out device includes an audible in/out transducer operable to convert an audible noise signal to a noise signal and convert an audio transmit (TX) signal to an audible output signal. A transducer signal of the audible in/out transducer generated by the audio TX signal is affected by the noise signal. The noise canceling audio in/out device further includes a noise canceling circuit operable to convert a digital TX signal to a TX reference signal, compare the transducer signal with the TX reference signal to produce an analog comparison signal, where the analog comparison signal includes a representation of the audio TX signal and the noise signal, and regulate the transducer signal to substantially match the TX reference signal to remove the effect of the noise signal on the transducer signal.

A device operative to transfer power wirelessly includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s). The DSC generates a drive signal based on a reference signal and provides the drive signal to a first coil via a single line and via a resonating capacitor, and simultaneously senses the drive signal via the single line, to facilitate electromagnetic coupling to a second coil to transfer power wirelessly to another device. The DSC also detects electrical characteristic(s) of the drive signal. The processing module(s) generates the reference signal and processes the digital signal to determine the electrical characteristic(s) of the drive signal. In some examples, the processing module(s) adapts the reference signal based on detection of the other device (e.g., based on interpreting the electrical characteristic(s) of the drive signal).
