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: In accordance with an embodiment, a detection device includes: an infrared temperature sensor configured to provide a temperature signal associated with an heat emission of at least one individual within a monitored area; an electrostatic-charge-variation sensor configured to provide a charge-variation signal indicative of a variation of electrostatic charge associated with the at least one individual; and a processing unit, coupled to the infrared temperature sensor and to the electrostatic-charge-variation sensor, the processing unit configured to detect a presence of the at least one individual within the monitored area by receiving the temperature signal and the charge-variation signal, and jointly processing the temperature signal and charge.

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.
