  • Patent number: 10832793
    Abstract: In some examples, a defective memory cell detection circuitry is configured to provide a failure signal indicative of a failure of a sub-group of memory cells (e.g., a row of memory cells). The failure signal is generated responsive to the failure of a sense line to transition to one of a set of reference voltages within a threshold time from a memory command. In some examples, failure signals indicative of a failure of a sub-group of memory cells is used by vehicle computer control systems to operate a vehicle.

  • Publication number: 20200291932
    Abstract: An automatic self-driving pump system features a pump/motor/drive detector and an automatic self-driving and control design/setup module. In operation, the pump/motor/drive detector receives sensed signaling containing information about a pump/drive for operating in a hydronic pump system, e.g., stored in and sensed from a signature chip or barcode installed that can be scanned by a scanner, and provides corresponding database signaling containing information about parameters for providing automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the sensed signaling received. The automatic self-driving and control design/setup module receives the corresponding database signaling, and provides control signaling containing information for providing the automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the corresponding database signaling received.
