Abstract: A detection device includes a pressure sensor, which provides a pressure signal indicative of an ambient pressure in an operating environment. An electrostatic-charge-variation sensor provides a charge-variation signal indicative of a variation of electrostatic charge associated with the operating environment, and processing circuitry is coupled to the pressure sensor and to the electrostatic-charge-variation sensor so as to receive the pressure signal and the charge-variation signal, and jointly processes the pressure signal and the charge-variation signal for detecting a variation between a first operating environment and a second operating environment for the detection device. The second operating environment is different from the first operating environment.

Abstract: A method for testing the hermetic seal of a packaged device, which includes: a package that delimits a device chamber; and a transducer device, which is arranged within the device chamber and generates an electrical signal indicating at least one physical quantity external to the package. The testing method includes the steps of: imposing a reference pressure in the device chamber; arranging the packaged device in a testing chamber in which a testing pressure is present, different from the reference pressure; and subsequently detecting possible pressure variations within the device chamber.

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 collecting, at a building opening, air pressure signals from a pressure sensor and sound signals from a sound sensor. The method also includes sensing pressure peaks occurring in the air pressure signals and sensing sound pulses occurring in the sound signals. A joint occurrence of a pressure peak in the air pressure signals and a sound pulse in the sound signals is indicative of an opening/closing event of the building opening.

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.
