Abstract: A voltage regulator is embedded in a circuit intermediate a first node (coupled to a battery) and a second node (supplying power to an external memory). The voltage regulator is activatable in a first mode of operation for startup during which an voltage is applied to the second node that increases towards a supply threshold. In response to the voltage at the second node reaching the supply threshold, the voltage regulator transitions to a second mode of operation where a programmable regulated voltage (higher than the supply threshold) is applied to the second node. In response to receipt of a low-power operation request, a first high-drive regulator circuitry is deactivated and a second low-power regulator circuitry is activated to provide a third mode of operation at low power.

Abstract: A closed container includes a detection device for detecting opening of or an attempt to open the container. The detection device includes a contactless passive transponder that is configured to communicate with a reader via an antenna using a carrier signal. An integrated circuit of the transponder includes two input terminals connected to the antenna and two output terminals linked by a first electrically conductive wire having a severable part which is severed in the event of an opening of or an attempted opening of the container. A shorting circuit is configured to short-circuit a first output terminal with a first input terminal in the event of a conductive repair of the severed part which forms an electrical connection between the two output terminals.

Abstract: A method is presented for monitoring a tampering state of closed container wherein a first electrically conductive wire extends across a slot between two portions of the closed container. The method includes applying a voltage across the first electrically conductive wire, sensing a voltage at one end of the first electrically conductive wire, and generating a signal indicating the tampering state of the closed container in response to the sensed voltage. The sensed voltage has a first voltage value if the first electrically conductive wire has been severed by tampering, and this tampered state is then reported using near field communication. The near field communication is blocked if it is sensed that the severed first electrically conductive wire has been repaired.
