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 low voltage drive circuit includes a transmit digital to analog circuit that converts transmit digital data into analog outbound data by: generating a DC component; generating a first oscillation at a first frequency; generating a second oscillation at the first frequency; and outputting the first oscillation or the second oscillation on a bit-by-bit basis in accordance with the transmit digital data to produce an oscillating component, wherein the DC component is combined with the oscillating component to produce the analog outbound data, and wherein the oscillating component and the DC component are combined to produce the analog outbound data. A drive sense circuit drives an analog transmit signal onto a bus, wherein the analog outbound data is represented within the analog transmit signal as variances in loading of the bus at the first frequency and wherein analog inbound data is represented within an analog receive signal as variances in loading of the bus at a second frequency.

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 display control unit includes a data drive unit, a gate drive unit, a drive settle detection circuit, and a row enable module. The data drive unit generates data drive signals for driving data lines of a display. The gate drive unit drives gate lines of the display in an order based on a row enable signal. The drive settle detection circuit monitors a set of data drive signals for an activated gate line. The drive settle detection circuit also sets a settled signal for the activated gate line when each drive signal of the set of drive signals has reached a corresponding settling threshold. The row enable module ends, as part of the row enable signal, activation of the activated gate line based on the settled signal and activates, as part of the row enable signal, another gate line based on the settled signal.

Abstract: A digital decimation filtering circuit of an analog to digital conversion circuit includes an n-tap anti-aliasing filter operable to receive a 1-bit analog to digital converter (ADC) output signal at an oversampling rate and filter the 1-bit ADC output signal to remove frequencies higher than a selected cut-off frequency to produce an n-bit filtered signal at a first data output rate. The digital decimation filtering circuit further includes a decimator operable to receive the n-bit filtered signal at the first data output rate, decimate the n-bit filtered signal by a decimation factor to produce a set of output signals, and sum the set of outputs to produce a decimated signal at a second data output rate. The first data output rate is greater than the second data output rate.
