  • Patent number: 11453280
    Abstract: An insert for a run slide for a vehicle window. The insert may be overmoulded to form a connecting wedge between two strands of the run slide. The insert may be formed in one piece and is configured to cooperate with a portion of a vehicle door frame. The insert is further configured to cooperate with a portion of a hubcap to be attached to one of the strands. The insert includes a protruding pin configured to be engaged in a recess of a rabbet of the vehicle door frame to index the insert along an axis X substantially parallel to an axis of elongation of the rabbet. The insert is configured to cooperate with the portion of the hubcap to ensure indexing the hubcap along the axis X and along an axis Z perpendicular to X and substantially parallel to an axis of elongation of the hubcap.

  • Publication number: 20200189371
    Abstract: An insert for a run slide for a vehicle window, the insert being intended to be overmoulded to form a connecting wedge between two strands of the run slide, the insert being formed in one piece and comprising first indexing means configured to cooperate with a portion of a vehicle door frame and second indexing means configured to cooperate with a portion of a hubcap to be attached to one of the strands, wherein the first means comprise at least one protruding pin configured to be engaged in a recess of a rabbet of the vehicle door frame to index the insert along an axis X substantially parallel to an axis of elongation of the rabbet, and wherein the second means are configured to cooperate by complementarity of shapes with the portion of the hubcap to ensure indexing the hubcap along the axis X and along an axis Z perpendicular to X and substantially parallel to an axis of elongation of the hubcap.

  • Patent number: 10495512
    Abstract: A method for obtaining, for at least one pixel of an image sensor comprised in an optical device, parameters defining a pixel beam is described. The method is remarkable in that it includes determining a direction of a chief ray associated with at least one pixel of the image sensor from the features of an optical system associated with the optical device, determining a set of pixels formed in a screen of a display device, the set of pixels comprising at least one pixel close to a point corresponding to an intersection of the chief ray and the screen, and the set of pixels comprising only pixels which are detected by the at least one pixel of the image sensor, when they are illuminated.

  • Patent number: 4633603
    Abstract: A snow removal apparatus adapted to be mounted on a vehicle, for removing snow from a light fixture protruding from the ground. Structure is provided for creating a flowing stream of air and a nozzle connected to the air stream directs the air stream at the ground, the directed stream of air having a flow velocity of at least about 180 m.p.h. The nozzle is adapted to be operatively positioned adjacent the ground at an angle to deflect the directed air stream on the ground at a predetermined distance from the light fixture so as to cause the deflected air stream to impinge on the light fixture at a reduced velocity sufficient to remove snow therefrom without damaging same, and to spread over a surrounding area with sufficient pressure to clear the area of snow.

  • Patent number: 4575492
    Abstract: The present invention relates to a process and device for the detection and quantification of agglutinates, in recipients of which at least the bottom are transparent. According to the invention, it is decided that there is agglutination when, at the same time, the calculated mean value of the bottom of the reaction studied is higher than that of a reference sample and when there exist points of measurement whose transmission is less than said threshold, and, on the other hand, that there is no agglutination when, at the same time, this calculated mean value is not greater than that of said reference sample and when there exist no points of measurement whose transmission is less than said threshold. The invention is more particularly applicable to immunohaematology.
