摘要： A method includes a processing module obtaining touch data at a touch data rate. The method further includes the processing module obtaining video data at a refresh rate, wherein the touch data rate is greater than the refresh rate. For a frame of the video data, the method further includes the processing module determining a touch movement trend based on the touch data. The method further includes the processing module determining a position offset for a graphical representation of the touch data based on the touch movement trend. When the position offset exceeds an offset threshold, the method further includes the processing module adjusting position of the graphical representation of the touch data within the frame of video data based on the position offset to produce an adjusted frame of video data.

摘要： A touch sensor device (TSD) includes a panel that includes electrodes and drive-sense circuits (DSCs). Different electrodes may be implemented in different directions. A first DSC is operably coupled via a first single line to a first electrode, and a second DSC is operably coupled via a second single line to the panel. The DSCs operate by providing respective signals via the respective single lines and simultaneously sensing the signals. For example, sensing of a first signal of a first DSC includes detection of a first electrical characteristic of the first electrode and/or a first change of the first signal. Sensing of a second signal of the second DSC includes detection of coupling of another signal into the panel in accordance with digital data communication from another device to the TSD. The DSCs also generate respective digital signals based upon what they sense.

摘要： A touch screen display includes a display, a video graphics processing module, electrodes integrated into at least a portion of the display, and drive-sense circuits coupled to the electrodes. The drive-sense circuits, when enabled and concurrent with the display rendering frames of data into the visible images, detect changes in electrical characteristics of electrodes. At least some drive-sense circuits monitor sensor signals on at least some electrodes. A sensor signal includes a drive signal component and a receive signal component. The at least some drive-sense circuits generate the drive signal components of the sensor signals. The receive signal component is a representation of a change in an electrical characteristic of an electrode of the at least some electrodes when a corresponding drive signal component is applied to the electrode. The change in the electrical characteristic of the electrode is indicative of a proximal touch to the touch screen display.

摘要： An automated system includes transducers, at least one computing device, and at least one automated apparatus. The transducer(s) is/are driven and sensed using drive-sense circuit(s). A drives and senses drive and sense a transducer via a single line, generates a digital signal representative of a sensed analog feature to which the transducer is exposed, and transmits the digital signal to the computing device. The computing device receives digital signals from at least some of drive-sense circuits and process them in accordance with the automation process to produce an automated process command. The automated apparatus executes a portion of an automated process based on the automated process command.

摘要： 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.
