    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 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 confined data communication system includes a reference generation circuit operable to produce one or more analog reference signals, an analog to digital converter circuit operable to process an analog signal to produce a digital representative signal, a digital filtering circuit operable to filter the digital representative signal to produce an affect value, a data processing module operable to interpret the affect value to produce processed output data, and a processing module operable to set frequency and waveform for each of the one or more analog reference signals, set digital filtering parameters for the digital filtering circuit, set a sampling rate for the analog to digital converter circuit, and set data interpretation parameters for the data processing module.

    Abstract: A method for execution by a low voltage drive circuit (LVDC) operably coupled to a bus includes, when activated, setting data reception for a control channel of a plurality of channels on the bus, where the control channel is a sinusoidal signal having a known frequency. The method further includes receiving the control channel and capturing a cycle of the control channel when the control channel is void of a data communication. The method further includes comparing the cycle of the control channel with a cycle of a first receive clock signal of the LVDC and when the cycle of a first receive clock signal compares unfavorably to the cycle of the control channel, adjusting phase and/or frequency of the cycle of the first receive clock signal to substantially match phase and/or frequency of the cycle of the control channel to produce an adjusted first receive clock signal.
