Abstract: A system for diagnosing the operating state of a MEMS sensor includes a stimulation circuit, external to the MEMS sensor, configured to generate a stimulation signal designed to be detected by the MEMS sensor. The system has control circuitry, operatively coupled to the stimulation circuit and to the MEMS sensor, so as to control the stimulation circuit to generate the stimulation signal and receive a diagnostic signal generated by the MEMS sensor in response to the stimulation signal. The control circuitry determines an operating state of the MEMS sensor based on the diagnostic signal and an expected response to the stimulation signal by the MEMS sensor.

Abstract: An embodiment method for controlling at least one functionality of an electronic device on the basis of a gesture of a user comprises detecting, by a sensor, a variation of electrostatic charge of the user during the execution of the gesture and generating a charge variation signal. The gesture includes moving at least one foot upward and, subsequently, downward. The method further includes, by a processing unit, acquiring the charge variation signal, detecting, in the charge variation signal, a characteristic identifying the gesture of moving the foot upward, detecting, in the charge variation signal, a characteristic identifying the gesture of moving the foot downward, and controlling the functionality of the electronic device only in the event that both the first and the second characteristics have been detected.

Abstract: A method includes applying heat to a metal oxide sensing element of a gas sensor, varying the heat applied to the metal oxide sensing element for at least a time interval, and measuring an electrical resistance of the metal oxide sensing element versus variation of the heat for a time interval. The measurement of electrical resistance of the metal oxide sensing element versus variation of the heat applied to the metal oxide sensing element is compared to a set of corresponding reference measurements associated with a plurality of different target gases. A further sensor parameter versus the variation of electrical resistance and variation of the heat applied is measured to obtain a three-dimensional trajectory corresponding to variation of the sensor resistance, the variation of said heat and the variation of the further sensor parameter. This comparing includes comparing the trajectory in three dimensions to a set of reference three-dimensional objects.

Abstract: A method of reducing power consumption in portable devices includes providing a sensor producing a sensing signal indicative of sensed entity and powering the sensor. Powering the sensor includes providing a first power value for a first time interval, providing a second power value for a second time interval, the second power value being different from the first power value, and discontinuing powering for a third time interval.

Abstract: A system for detecting a presence in an environment to be monitored includes an electrostatic charge variation sensor, a vibration sensor, and an environmental pressure sensor. A processing unit is configured to acquire, from the electrostatic charge variation sensor, an electrostatic charge variation signal, and detect in the electrostatic charge variation signal, first signal characteristics indicative of the presence of a subject in the environment to be monitored. The processing unit further validates the detection of presence of the subject using the vibration and pressure signals provided by the other sensors.

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.

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.
