  • Patent number: 11947761
    Abstract: An encoded data pattern touchscreen sensing computing device includes a touchscreen, a plurality of electrodes, a plurality of drive-sense circuits, and a processing module. When enabled and in close proximity to an encoded data pattern, the plurality of drive-sense circuits detect changes in electrical characteristics of the plurality of electrodes caused by one or more electrical materials of the encoded data pattern. The encoded data pattern includes one or more electrical materials arranged in a pattern. Electrical properties of the one or more electrical materials and the pattern are representative of data. The processing module is operable to receive a set of detected changes in electrical characteristics of the set of drive-sense circuits, interpret the detected changes in electrical characteristics as a set of impedance values representative of the one or more electrical materials of the encoded data pattern, and interpret the set of impedance values to determine the data.

  • Patent number: 11940504
    Abstract: A Hall effect sensor system includes a Hall effect sensor and a drive-sense circuit (DSC). The Hall effect sensor includes an input port to receive a DC (direct current) current signal and generates a Hall voltage based on exposure to a magnetic field. The DSC generates the DC current signal based on a reference signal and drives it via a single line that operably couples the DSC to the Hall effect sensor and simultaneously to sense the DC current signal via the single line. The DSC detects an effect on the DC current signal corresponding to the Hall voltage that is generated across the Hall effect sensor based on exposure of the Hall effect sensor to the magnetic field and generates a digital signal representative of the Hall voltage.

  • Publication number: 20240094854
    Abstract: A touch sensor device (TSD) includes TSD electrodes associated with a surface of the TSD. Also, an overlay that includes marker electrode(s) is also associated with a region of the surface of the TSD. The TSD also includes drive-sense circuits (DSCs) operably coupled to the plurality of TSD electrodes. A DSC is configured to provide a TSD electrode signal to a TSD electrode and simultaneously to sense a change of the TSD electrode signal based on a change of impedance of the TSD electrode caused by capacitive coupling between the TSD electrode and the marker electrode(s) of the overlay. Processing module(s) is configured to process a digital signal generated by the DSC and other digital signals generated by other DSCs determine the region of the surface of the TSD that is associated with the overlay and to adapt sensitivity of the TSD within that region.

  • Publication number: 20240096406
    Abstract: A method for execution by a Dynamic Random Access (DRAM) cell processing circuit in a read mode, includes receiving a pre-charge input and charging a bit-line operably coupled to a plurality of DRAM cells of a DRAM memory device, including a current DRAM cell, to a pre-charge voltage. The method continues by sensing a voltage change on the bit-line, where the sensing is based on a difference between a voltage stored on a DRAM cell capacitor of the current DRAM cell and the pre-charge voltage and generating a logic input for one of four voltage states for the current DRAM cell. The method then continues by supplying, supplying, based on the logic input, a corresponding logic voltage on the bit-line to refresh the voltage stored in the DRAM cell capacitor of the current DRAM cell.

  • Patent number: 11933607
    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: 5779057
    Abstract: Disclosed is a rigid removable carrier tray for transporting and storing pin sockets. The tray includes one or more arrays of holes of consistent or varying diameter disposed in an upper surface and formed to receive pin sockets. Pin sockets are recessed below the upper surface of the carrier tray when placed in the holes. A flexible adhesive film is disposed over the upper surface of the carrier tray to prevent the pin sockets from falling out of the carrier tray during transport. The pin sockets are installed by removing the adhesive film and press fitting the leads of an integrated circuit ("IC") chip into the pin sockets in the holes. The holes in the array may be arranged in a customized pattern in order to accommodate a particular IC chip, or may be arranged in a generic pattern to accept a variety of IC chips. The carrier tray also includes standoffs with alignment guides and troughs that facilitate stacking and storage.
