  • Patent number: 11332218
    Abstract: An attachment of a stockless anchor on the sea floor encourages flukes to tilt as soon as the vessel pulls away, while maintaining stability on the floor. The weight of the flukes act as a pivot with the crown of the stockless anchor that, when placed on the floor, causes the anchor to become attached by being buried in the floor when the vessel pulls away. The attachment comprises two claws fastened to the flanks of the flukes at or in close proximity of the crown on the pivot axis of the flukes, thereby enabling them to tilt and become attached immediately in the floor as soon as the anchor is placed on the floor. When the vessel pulls away the anchor is open and becomes attached immediately. An attachment to the floor avoids or reduces dragging of the anchor on the floor.

  • Patent number: 8232836
    Abstract: The invention relates to an integrated circuit comprising a succession of N identical elementary circuits (CE1, CE2, . . . CEN), juxtaposed in the order of their rank j varying from 1 to N, N being at least equal to 50, and all having to receive two reference potentials Vref and V0 supplied by two conductors. An upstream input of the second conductor is situated geographically on the side of the rank 1 of the succession of juxtaposed circuits, and an upstream input of the first conductor is situated geographically on the side of the rank N of the succession of juxtaposed circuits. This reduces the error in the potential difference applied to the elementary circuits all along the succession, an error that originates from the non-zero resistance of the conductors. The integrated circuit is applicable to analog-digital converters or digital-analog converters with high resolution.

  • Patent number: 7999713
    Abstract: The invention relates to fast, high resolution, analog digital converters, and more particularly those which possess at least one conversion stage of “flash” type. The converter according to the invention uses N differential amplifiers with four inputs. The amplifier of rank j receives the input voltage to be converted Vep?Ven on two first inputs, and a reference potential difference on two other inputs. The reference potential difference is obtained between two taps of networks of resistors that are identical operating in parallel and supplied between a high voltage source and a low current source; the taps for an amplifier are respectively a tap Pj of rank j of a first network and a tap P?N?j+1 of rank N?j+1 of a second network. This reduces the first and second order non-linearity effects due to the fact that the differential amplifiers consume an input current tapped off from the networks of resistors.

  • Publication number: 20100242434
    Abstract: The method of the invention for monitoring a thrust reverser of a turbojet having an actuator controlled by an electric motor consists in determining a maintenance notice from a weighted combination of provisional notices, each provisional notice relating to a category of parameters associated with at least one phase of an operating cycle of the reverser, the category being selected from a category of parameters representative of a duration of said phase, of an energy seen by the motor during said phase, of a torque seen by the motor at a predefined instant of said phase, and of a duration during which the setpoint speed of rotation and the measured speed of rotation of the motor differ during said phase, each provisional notice being generated by analyzing values obtained during at least one cycle for at least one parameter of said category relative to a degradation threshold.

  • Publication number: 20060074487
    Abstract: A device for treating an eye affection related to a decrease of ocular accommodation amplitude resulting from loss of tension of the zonular fibers caused by increase in the lens diameter. The device is designed to be surgically implanted in the ciliary sulcus, behind the iris, and configured to compensate the loss of tension of the zonular fibers by exerting on the ciliary sulcus a pressure tending to increase its diameter. The device includes a closed tubular envelope made of an elastic and fluid-impermeable material, the envelope being shaped like a ring or a ring portion having a predetermined outer diameter at rest, the inner ring wall of the envelope delimiting a lumen adapted to be filled with an incompressible fluid tending to increase the outer diameter up to a value whereby the loss of tension of the zonular fibers is compensated.
