  • Patent number: 11954260
    Abstract: A system and method for determining handedness in a device. The system including a first electrode, a second electrode, a sensor, and a processing circuit coupled to each other. The first electrode is placed at a first location, and the second electrode is placed at a second location on the device—the first location is different from the second location. The electrodes are configured to sense a variation in an electrostatic field in response to a user interacting with the device. The sensor detects a differential potential between the first electrode and the second electrode, and the processing circuit determines whether the user is interacting with the device using a left hand or a right hand. The determining is based on data received from the sensor corresponding to the differential potential.

  • Patent number: 11956324
    Abstract: An integrated circuit includes sensing circuitry and processing circuitry. The processing circuitry processes received sensor-session requests and received sensor-service requests. Processing a received sensor-service request includes determining a type of the received sensor-service request. In response to determining the received sensor-service request is of a first type, results information is generated in response to the received sensor-service request of the first type based on sensor data generated by the sensing circuitry. In response to determining the received sensor-service request is of a second type, remote-server processing based on the received sensor-service request of the second type is initiated, and a response to the received sensor-service request of the second type is generated based on a received response to the initiated remote-server processing.

  • Patent number: 11847897
    Abstract: A method for presence detection in an environment to be monitored, includes generating an electric charge signal in a condition of absence of presence in the environment to be monitored. An electric charge signal is generated in an operating condition in which a person may be present in the environment. The two generated signals are processed and the results of the processing are compared. Processing the signals includes representing in a biaxial reference system the value of the charge signal considered and its derivative with respect to time, and identifying a plurality of points in the reference system. By comparing the position of the points acquired during the possible human presence with those of the base shape, a variation indicating the actual human presence may be detected. In this case an alarm signal is generated.

  • Patent number: 11788980
    Abstract: A sensor is driven at a first heating power value. The sensor generates a sensing signal that is indicative of a sensed entity. A possible onset of a sensor contamination condition is detected as a function of the sensing signal generated by the sensor. If such detecting fails to indicate onset of a sensor contamination condition, the sensor continues to be driven at the first heating power value. However, if such detecting indicates onset of a sensor contamination condition, a protection mode is activated. In the protection mode, the sensor is driven at a second heating power value for a protection interval, where the second heating power value is lower than the first heating power value. Furthermore, the operation may refrain from supplying power to the sensor for a further protection interval, wherein the further protection interval is longer than the protection interval.
