  • Patent number: 7061985
    Abstract: A modulation/demodulation device capable of operating with several types of modulation using different carrier frequencies may include a modulator which modulates at least one signal by a signal of a predetermined duration and representative of a binary information supplied by a microprocessor. The device may also include a demodulator which demodulates the modulated signals arriving from a remote site. This may be done by determining the type of modulation of the received signals and their carrier frequency (or frequencies), supplying signals from an analysis of the signals received according to the determined type of modulation, and detecting the signals of determined duration representative of binary information to make them accessible to the microprocessor.

  • Patent number: 6263324
    Abstract: A fuzzy logic processor placed in a home automation communications network manages messages traveling through the network. To manage the messages, the fuzzy logic processor works in two stages. In a first stage, on a first part of the message, the fuzzy logic processor ascertains that the message is addressed to it, according to rules by which it recognizes that it is the addressee. Once it recognizes that it is the addressee, it is also capable of producing a routing command because the address of the sender of the signal is present in the message. This routing command is applied to a multiplexer located at the input, interfacing between the fuzzy logic processor and the network in order to route data elements, constituting another part of the message, to the appropriate input of the fuzzy logic processor.

  • Patent number: 6049071
    Abstract: A power supply device for a non-linear load, especially a magnetron for microwave ovens, includes a resonant transformer. Using a fuzzy logic management unit, a level of a low voltage signal on the primary side of the transformer, a level of high voltage signal on the secondary side of the transformer, and a signal corresponding to the ambient temperature of the transformer are taken into account for the generation of a parameter for a control signal for controlling a switch positioned at the primary winding of the transformer. The power supply device makes it possible to reduce the size of the resonant transformer.

  • Patent number: 5809234
    Abstract: Problems of matching an interface to a transmission protocol are resolved by implementing fuzzy logic. A set of fuzzy logic rules is used to select transmission parameters based upon degrees of membership of characteristics of a received signal. The characteristics may be time duration of bits, number of bits, parity value, and duration of stop bit, for example. As a result, the receiving circuits get simplified and even become universal.

  • Patent number: 5739673
    Abstract: A battery-charger uses a fuzzy logic microprocessor. The use of fuzzy logic makes it easier to take account of the diversity of the types of batteries to be charged and to control the state of the batteries charged while, at the same time, producing a battery at very low cost, whereas these functions are normally carried out by far bigger microprocessors. The invention can be applied especially to the charging of batteries assembled to constitute powerful energy sources, that are used especially for automobile haulage, large-scale consumer articles, professional and industrial equipment or computer equipment.
