Patent number: 7061985Abstract: 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.Type: GrantFiled: October 26, 2001Date of Patent: June 13, 2006Assignee: STMicroelectronics SAInventor: Maurice Le Van Suu

Patent number: 6263324Abstract: 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.Type: GrantFiled: February 18, 1998Date of Patent: July 17, 2001Assignee: SGS-Thomson Microelectronics S.A.Inventor: Maurice Le Van Suu

Patent number: 5809234Abstract: 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.Type: GrantFiled: February 20, 1996Date of Patent: September 15, 1998Assignee: SGS-Thomson Microelectronics S.A.Inventor: Maurice Le Van Suu
