  • Patent number: 10731699
    Abstract: The invention relates to a pivot connection type assembly comprising a shaft and first and second connection parts, each receiving the shaft so as to enable them to pivot relative to each other, the first connection part being arranged axially between a first end of the shaft and a radial plane, while the second connection part is arranged axially between said radial plane and the other end of the shaft. The shaft is hollow and includes an inside section that presents a radial dimension at least in a first axial plane and over a first segment of the shaft extending axially between the first end and the radial plane, which radial dimension varies, decreasing on axially approaching the radial plane. The assembly includes a ring interposed radially between the shaft and a bore of the first connection part, and presenting radial thickness that varies.

  • Publication number: 20190147408
    Abstract: A method for determining a meeting point location of a plurality of users willing to meet and each having associated thereto a respective user terminal is disclosed. Each said terminal has a capability of communications with the other user terminals and has a positioning system providing position information of the terminal. The method comprises the following steps: (a) obtaining from the plurality of user terminals the position information thereof and constraints, (b) calculating an appropriate meeting point location based on the user terminal positions and the constraints, and (c) communicating information about the meeting point location to each one of said terminals.

  • Patent number: 10017244
    Abstract: Provided is a method of fabricating a force transfer part including at least one lug made of composite material that is to receive a pin for making a pivot connection with another part. The method includes making a fiber preform for a main body of the part and making a preform for a reinforcing ring out of discontinuous long fibers, making the reinforcing ring preform to match the dimensions of at least one bore in the preform of the main body, inserting the reinforcing ring preform in the bore of the preform of the main body, and polymerizing the reinforcing ring and main body preforms in injection tooling. A force transfer part obtained by such a method is also provided.

  • Publication number: 20070262801
    Abstract: A pulse width modulation circuit comprising an oscillator, a ramp generator and a comparator where the offset level of the ramp generated by the ramp generator varies and where the value of the voltage supplied to the comparator is constant is described herein. By varying the offset level of the ramp, it is possible to modulate the width of the pulse of the output signal of the circuit.
