  • Patent number: 12181276
    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.

  • Patent number: 12056315
    Abstract: A method for determining for determining response for a touch display panel begins by receiving an analog input signal from a data drive input circuit that is operable to generate an analog input signal based on a digital input. The method continues by generating a reference signal voltage from the analog input signal, generating a data signal voltage from the analog input signal and using a difference detection circuit, outputting an analog output voltage. The method then continues by generating an error correction current based on the analog output voltage, where the error correction current adjusts the data signal voltage in order to keep inputs to the difference detection circuit substantially equal. Finally, the method finishes by generating a current representative of a light intensity for light received by a sensor cell associated with the touch display panel, converting the analog output signal into a digital representation of the current and producing information representative of light intensity.
