摘要： To recognize an authorized user from an unauthorized user of a portable electronic apparatus, the portable electronic apparatus has a plurality of sensors and a user-recognition circuit. The sensors are each configured to generate a signal representative of a respective physical quantity associated with the use, by a user, of the portable electronic apparatus in an operating state. The user-recognition circuit is configured to receive a plurality of electrical signals from the plurality of sensors; determine a plurality of recognition parameters, each associated with a specific mode of use of the portable electronic apparatus by the user; determine a plurality of indicators of use, one for each recognition parameter, wherein each parameter indicates the probability that, at a time instant, the respective recognition parameter is associable with an unauthorized user; determine a probability of intrusion from the plurality of indicators of use; and compare the probability of intrusion with an intrusion threshold.

摘要： In an embodiment a method for detecting an activity of a first eye of a user using glasses includes acquiring, by a controller and through first and second electrodes, a first electrostatic charge variation signal indicative of a difference between the electrostatic charge variations detected by the first and the second electrodes, verifying, by the controller, a presence of one or more blink patterns in the first electrostatic charge variation signal, each blink pattern being indicative of a respective click or of a respective blink, the click being a voluntary blink of the first eye and the blink being an involuntary blink of the first eye, when the first electrostatic charge variation signal has the one or more blink patterns, determining, by the controller for each blink pattern, whether a first condition is verified, when the first condition is not verified, detecting, by the controller, a respective blink and when the first condition is verified, detecting, by the controller, a respective click.

摘要： A sensor device for detecting a flame comprises a carbon dioxide sensor for detecting a CO2 concentration, a fuel sensor for detecting the combustion of a fuel, an electrostatic charge variation sensor for detecting electrostatic charge variations generated by the flame, and a control unit. The control unit is configured to acquire a carbon dioxide signal indicative of the concentration of carbon dioxide, a fuel signal indicative of the fuel combustion, and an electrostatic charge variation signal indicative of a difference between the electrostatic charge variations detected by a first and a second electrode of the electrostatic charge variation sensor, determine a quantized signal based on the electrostatic charge variation signal, determine an aggregate datum based on the carbon dioxide signal, the fuel signal and the electrostatic charge variation signal, and generate, based on the aggregate datum, a flame signal indicative of the presence or absence of the flame.
