  • Patent number: 11372028
    Abstract: Stand-alone remote sensor arrangement for monitoring parameter activity in a cable including a sensor unit, a power source unit, a connecting cable, and a control unit. The sensor unit includes a shielded housing enclosing a toroid-shaped core fixed around the cable to be monitored. The arrangement operates in a low current consumption mode and a measurement mode, in which measurement mode a Hall sensor element senses a predetermined parameter activity of the cable. The sensor unit includes a sensor activation unit arranged and structured to sense parameters related to magnetic field variations in the core caused by parameter activity of the cable, and to generate a sensor activation signal including parameter values dependent on sensed parameters. The control unit receives the signal and evaluates the parameter values in relation to predetermined mode changing criteria, and changes mode of operation of the arrangement dependent on the result of the evaluation.

  • Patent number: 11181402
    Abstract: Sensors in one or more remote devices provide sensor output to a device having a controller. The controller analyzes the sensor data to determine the accuracy of the sensors outputting the sensor data. Based on the analysis, the controller calculates a calibration value to utilize in calibrating one or more of the sensors in the remote devices, or in one or more other devices.

  • Patent number: 10948289
    Abstract: A base unit includes a sensor calibration function. When a user communicatively couples a consumer electronic device having a sensor to the base unit, a controller at the base unit retrieves a calibration reference value for the sensor and/or a sensor algorithm that utilizes data output by the sensor. The base unit then sends the calibration reference value to the consumer electronic device to set a sensor calibration parameter associated with the sensor and/or the sensor algorithm.
