摘要： An H-bridge circuit includes a supply voltage node, a first pair of transistors and a second pair of transistors. First transistors in each pair have the current paths therethrough included in current flow lines between the supply node and, respectively, a first output node and a second output node. Second transistors in each pair have the current paths therethrough coupled to a third output node and a fourth output node, respectively. The first and third output nodes are mutually isolated from each other and the second and fourth output nodes are mutually isolated from each other. The H-bridge circuit is operable in a selected one of a first, second and third mode.

摘要： A device includes a printed circuit board substrate, an antenna connected to the printed circuit board substrate, an amplifier connected to the printed circuit board substrate, and a matching track having a first end electrically connected to an input of the amplifier and a second end electrically connected to an output of the antenna. The matching track has an outgrowth that is symmetrical along a median axis of the outgrowth. The matching track is rectilinear and has a constant width over an initial part extending between the widening area and the first end. A median axis of the initial part and the median axis of the outgrowth form an angle comprised between 60 and 120°.

摘要： The system comprising a slave module and a master module. The master module comprises a master control module (CONTRM). The slave module comprises a determination module (DETER). The determination module (DETER) is configured to determine a value of a physical quantity of the slave module. The determination module (DETER) is configured to receive, from the master control module (CONTRM), a command to start counting and a command to end counting. The determination module (DETER) is configured to determine a number of oscillations, between reception of the command to start counting and reception of the command to end counting, of an oscillating signal of which a frequency depends on the value of the physical quantity.

摘要： A system on a chip comprising a set of one-time programmable memory elements that comprises a first valid configuration; a second valid configuration; and a plurality of invalid configurations. The system on a chip also comprises a programming indicator initially comprising a first value and configured to be permanently set to a second value. The system on a chip further comprises a decoder circuit in communication with the set of one-time programmable memory elements to determine whether the set of one-time programmable memory elements is in the first valid configuration, the second valid configuration, or any one of the plurality of invalid configurations. The decoder circuit generates a threat-detection signal when the set of one-time programmable memory elements is in any of the plurality of invalid configurations when the programming indicator is permanently set to the second value.
