    Abstract: A method for mutual authentication that includes establishing a first inductive coupling between a wireless-power receiver and a wireless-power transmitter to transfer power from the wireless-power transmitter to the wireless-power receiver by a power signal and using the power signal to transmit a first response to a physically unclonable function to the wireless-power transmitter. The method further including generating a second response to the physically unclonable function and communicating information derived from the second response to initiate a mutual authentication process between the wireless-power receiver and the wireless-power transmitter during a subsequent inductive coupling.

    Abstract: In one embodiment, a light assembly includes a base substrate; a light-emitting device supported by the base substrate; a cover permeable to volatile compounds, completely surrounding the light-emitting device and being transparent to a light flux emitted, during use, by the light-emitting device; a gas sensor configured to sense the volatile compounds, the gas sensor being arranged within the cover. The light assembly includes a pump having an inlet operatively coupled to the cover, and operable to generate a pressure depression within the cover. The light assembly includes a light sensor operatively coupled to the light-emitting device, the light sensor being configured to sense a light intensity value of at least one light component of the light flux. The light assembly includes a processor operatively coupled to the gas sensor, the light sensor, and the pump; a non-volatile memory storing a program to be executed in the processor.

    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.

    Abstract: A method of operating a gas sensing device is described. The method includes receiving a signal indicative of a value of resistance of a gas sensing element, processing the signal received to compute a value of a gas concentration, performing a comparison of the value of gas concentration to a threshold, and, based on the outcome of a diagnosis procedure, setting the device to an alert signal issue state as a function of the outcome of the comparison. The diagnosis procedure includes computing a set of parameters indicative of the state of the gas sensor circuit, and classifying the gas sensor circuit in one of a first, a second and a third class based on the parameters.

    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.
