Abstract: A microelectromechanical system (MEMS) sensor testing device, system and method are provided. The testing device includes a socket having a plurality of pads configured to receive a respective plurality of pins of the MEMS sensor, a body having a plurality of operable positions associated with a respective plurality of orientations of the MEMS sensor and circuitry which performs a method for testing the MEMS sensor in the plurality of operable positions. The method includes, for each position of the plurality of operable positions, outputting an indication of the position to the plurality of operable positions, receiving one or more measurements made by the MEMS sensor at the respective position and determining whether the one or more measurements satisfy a reliability criterion. The method includes generating a report based on the plurality of measurements and indicating whether the plurality of measurements satisfy a plurality of reliability criteria, respectively.

Abstract: An embodiment of an apparatus has a closed housing accommodating an element to be protected, and a pressure sensor coupled to a control unit configured to detect pressure variations within the housing upon opening the housing. The control unit is configured to activate countermeasures upon detecting opening of the housing. For example, the apparatus may be a set-top box, a cell phone, a television set, a printer ink cartridge of toner cartridge, or a meter, wherein the element to be protected is a semiconductor chip and relevant couplings, storing an enabling code or key.
