    Abstract: An analog to digital conversion includes a multiplexor circuit for receiving analog input signals and, responsive to a select input, an analog to digital converter circuit to convert a selected analog signal into a digital signal, a conversion starting device to send a conversion start signal on the basis of a trigger event, the conversion starting device being responsive to a select input, a sequencer to control the analog to digital converter circuitry to execute one sequence conversion on the basis of one conversion sequence instruction, and a FIFO register block to receive conversion sequence instructions and being able to queue each new received conversion sequence instruction if an actual conversion sequence is in progress and to control the sequencer to execute a new sequence conversion instruction after the conversion sequence is executed.

    Abstract: A security system includes an integrated circuit and a transceiver/transponder circuit. The integrated circuit includes an antenna for communicating with the transceiver/transponder circuit. An inhibiting element is associated with the integrated circuit for inhibiting communications with the transceiver/transponder circuit and for securing the data contained in the integrated circuit. The inhibiting element is an electromagnetic inhibiting element. The security system further includes a coupling element associated with the antenna of the integrated circuit for temporarily deactivating the electromagnetic inhibiting element to allow communications between the integrated circuit and the transceiver/transponder circuit.

    Abstract: A MEMS detection structure (10) comprising a substrate (2) having a top surface (2a) with at least a first fixed-electrode arrangement (5a); a sensing mass (3) extending in a plane (xy) and suspended above the substrate (2) and above the first fixed-electrode arrangement (5a) at a separation distance; and connection elastic elements (8a, 8b) supporting the sensing mass (3) for being freely rotatable out of the plane (xy), modifying the separation distance as a function of a detected quantity along an axis (z) orthogonal to the plane (xy). The MEMS detection structure further comprises a coupling mass (12), suspended above the substrate (2) and connected to the sensing mass (3) via the connection elastic elements (8a, 8b) and an anchoring arrangement (14, 15), which anchors the coupling mass (12) to the substrate (2) with at least a first point of constraint (13), set at a distance from the rotation axis (A) and in a position corresponding to the first fixed-electrode arrangement (5a).
