Abstract: An integrated device for driving a lighting load, such as a LED, has a first memory element, configured to store a nominal duty-cycle at a nominal supply voltage. An actual voltage acquisition element is configured to detect an actual supply voltage. A processing unit is coupled to the first memory element and to the actual voltage acquisition element and configured to calculate a voltage compensated duty-cycle. A driver unit is coupled to the processing unit and is configured to be supplied according to the voltage compensated duty-cycle.

Abstract: An antenna includes two planar coils that are mechanically disposed face to face and electrically connected in series. The antenna is mounted to a disposable consumer product (for example, a cartridge for use with an electronic cigarette). The antenna is configured to support near field communications with a reader circuit for purposes of authenticating use of the disposable consumer product.

Abstract: The power supply device comprises a supply transistor commanded by a command signal and providing electric power to a lighting module, and a driving means configured to selectively generate, depending on an instruction signal representative of the structure of said at least one lighting module, a first command signal able to command the supply transistor into an ohmic regime, a second command signal able to command the supply transistor into a pulse width modulation regime involving an alternation of ohmic regimes and blocked regimes, and a third command signal able to command the supply transistor into a saturated regime.

Abstract: A thermal control process for an electronic power device including a multi junction integrated circuit may include defining a first and at least one second groups of junctions, with each group including one first and at least one second junctions, and associating a thermal detector with each group. A first group control may be executed which detects group electric signals representative of the temperature detected by the thermal detectors, processes the group electric signals with reference to a group critical thermal event, identifies a critical group when the corresponding group electric signal detects the critical group thermal event, and generates group deactivating signals suitable for selectively deactivating the first and the at least one second junctions of the identified critical group with respect to the remaining junctions of the integrated circuit.

Abstract: A hardware secure module includes a processing unit and a cryptographic coprocessor. The cryptographic coprocessor includes a key storage memory; a hardware key management circuit configured to store a first cryptographic key in the key storage memory; a first interface configured to receive source data to be processed; a second interface configured to receive the first cryptographic key from the processing unit for storing in the key storage memory; a hardware cryptographic engine configured to process the source data as a function of the first cryptographic key stored in the key storage memory; and a third interface configured to receive a second cryptographic key. The hardware secure module further includes a non-volatile memory configured to store the second cryptographic key; and a hardware configuration module configured to read the second cryptographic key from the non-volatile memory and send the second cryptographic key to the third interface.

Abstract: A hardware secure element includes a processing unit and a receiver circuit configured to receive data comprising a command field and a parameter field adapted to contain a plurality of parameters. The hardware secure element also includes at least one hardware parameter check module configured to receive at an input a parameter to be processed selected from the plurality of parameters, and to process the parameter to be processed to verify whether the parameter has given characteristics. The hardware parameter check module has associated one or more look-up tables configured to receive at an input the command field and a parameter index identifying the parameter to be processed by the hardware parameter check module, and to determine for the command field and the parameter index a configuration data element.
