Abstract:
Circuit for the generation of two symmetrical buses of tension with respect to the negative of the feeding tension, comprising supply means able to supply a power step-up circuit comprising an inductor, a switch, a diode and a condenser, an LC filter being arranged in cascade to said power step-up circuit, a pair of switches with relevant re-circulation diodes being connected in cascade to said LC filter, whose peculiar aspect is that said supply means comprise a single supply source, and a circuit branch consisting of a condenser and a diode connected in series the one to the other and in parallel to said switch and said condenser of said power step-up circuit, a further inductor with diode in series being connected between the anode end of said circuit branch diode and a condenser connected symmetrically with respect to the condenser of said power step-up circuit.
Abstract:
An obstacle detection system, particularly for assisting car parking that comprises a control unit and a plurality of sensors, which comprise emitters-receivers for emitting an ultrasonic signal and for receiving an echo signal reflected by at least one obstacle and an evaluator for the parametric evaluation of the received echo signals, the evaluator comprising a polling module suitable to determine, for each sensing, the number of times for which the received signals are repeated and to reject the signals that are repeated for a number of times that is lower than a preset number.
Abstract:
A method for the automatic addressing of elements connected to a control unit by means of a single bus and comprising a switch suitable to manage the connection to the power supply of a subsequent adjacent element, the method comprising the steps of sending over the bus a command so that the elements send in response an identification signal toward the control unit; receiving from an element a signal that corresponds to the “unassigned address” state; sending over the bus a command to assume an identification address; and assuming, on the part of the element that sent the “unassigned address” state signal, the identification address and closing the switch for connection to the subsequent element.
Abstract:
