Device and method for detecting a change in operating environment for an electronic apparatus

An electronic apparatus, comprising:

• a detection device, including:
• a pressure sensor configured to provide a pressure signal indicative of an ambient pressure in an operating environment;
• an electrostatic-charge-variation sensor configured to provide a charge-variation signal indicative of a variation of electrostatic charge associated with said operating environment;
• and
• processing circuitry coupled to the pressure sensor and to the electrostatic-charge-variation sensor and configured to receive the pressure signal and the charge-variation signal and to jointly process the pressure signal and the charge-variation signal and detect a variation between a first operating environment and a second operating environment for the detection device, the second operating environment being different from the first operating environment;
• and
• a main controller coupled to the processing circuitry of the detection device and configured to receive a variation signal, indicative of the change in operating environment, for execution or activation of given actions in response to detection of the change in operating environment.

A method for detecting a variation between a first operating environment and a second operating environment, different from the first operating environment, comprising:

• receiving, from a pressure sensor, a pressure signal indicative of an ambient pressure in an operating environment;
• receiving, from an electrostatic-charge-variation sensor, a charge-variation signal indicative of a variation of electrostatic charge associated with the operating environment;
• and
• jointly processing the pressure signal and the charge-variation signal and detecting the change between the first operating environment and the second operating environment, different from the first operating environment.
