    Abstract: A tag adapted to be applied to an object is disclosed. The tag includes a wireless communication interface, a processor and a memory. A univocal code, a cipher key and a count value are store in the memory. The tag generates a dynamic code as a function of the cipher key and the count value. Next, the tag varies the count value according to a determined operation, and stores the varied count value in the memory. The tag transmits the univocal code and the dynamic code to a reader device. The tag may transmit the univocal code and the dynamic code in a URL.

    Abstract: An exemplary package comprises a smart card having a first side and a second side, the first side comprising a first area having reproduced thereon first readable information and a second area having reproduced thereon second readable information. The first side having a laminar member applied so as to cover the first side, the laminar member comprising a light-impermeable material and a first light-permeable portion at the first side. The first readable information is visible through the first light-permeable portion and the second readable information is covered and made invisible by the light-impermeable material. A light-permeable film material is wrapped onto the smart card having the laminar member applied thereon.

    Abstract: A high voltage driving circuit for driving a load receives a low voltage input signal and generates a high voltage output signal. A short circuit protection circuit including a first electronic switch operated by the low voltage input signal and a second electronic switch operated by a low voltage signal obtained by a voltage division of the output high voltage signal. The first electronic switch causing a first pull-up current to be sent to a capacitive element whose voltage controls an input of a threshold comparator. A second electronic switch causes a second pull-down current to be drawn from the capacitive element whose voltage controls the input of the threshold comparator. A short circuit detection signal is generated at an output of said threshold comparator, indicating a short circuit and capable of inhibiting operation of the driving circuit.

    Abstract: A MOSFET device comprising: a structural region, made of a semiconductor material having a first type of conductivity, which extends between a first side and a second side opposite to the first side along an axis; a body region, having a second type of conductivity opposite to the first type, which extends in the structural region starting from the first side; a source region, having the first type of conductivity, which extends in the body region starting from the first side; a gate region, which extends in the structural region starting from the first side, traversing entirely the body region; and a shielding region, having the second type of conductivity, which extends in the structural region between the gate region and the second side. The shielding region is an implanted region self-aligned, in top view, to the gate region.

    Abstract: An integrated circuit includes a die that includes a circuit configured to generate a PWM signal in response to a first clock signal, and a first set of pads configured to provide amplified PWM signals to external filters. An amplifier stage is configured to provide the amplified PWM signals. The die includes two pads configured to be coupled to an external inductor, and a second set of pads configured to provide regulated voltages. An electronic converter circuit is configured to generate the regulated voltages to supply the amplifier stage. The electronic converter circuit includes a control circuit configured to drive electronic switches in response to a second clock signal to regulate the regulated voltages to a respective target value. The die includes a control block to synchronize the switching activity of the electronic switches with the switching activity of the amplifier stage.
