  • Device for measuring the mechanical load exerted by a fluid using an electromechanical transducer
    Patent number: 7698953
    Abstract: A measuring device comprising: a sensor (1) with at least one electromechanical transducer (10); at least one electrical generator connected to said transducer; and means for measuring the electrical input impedance of the transducer. Said sensor (1) has an empty space (12) passing therethrough within which a substance (14) can flow, and said transducer (10) is situated at the periphery of said empty space (12) in such a manner as to be subjected to a mechanical load characteristic of the substance (14) flowing in said space (12), the measured electrical impedance being a function of said load. The device is suitable for use in a measuring apparatus seeking to determine the density of the substance (14) flowing inside said tubular space (12).

  • Electronic telephone switching system of the stored program type comprising two active stages and one passive stage
    Patent number: 4095054
    Abstract: Improved electronic program-controlled switching system intended to be used in connection with automatic telephone switching. The system comprises a common control equipment responsible solely for information processing and comprising at least one program memory and one data memory, and individual peripheral circuits each connected to said control equipment and which are logic circuits with special-purpose wired programs connected to the requisite systems comprising line equipment, connection network, auxiliary circuits and circuits for connection to the main network. The system allows decentralizing the main functions in the peripheral equipments.
