  • Method of adjusting a display of binocular type comprising a pair of spectacles and display for the implementation of this method
    Patent number: 8820919
    Abstract: The invention provides an adjustment method for adjusting a binocular display, the display comprising for each eye of the wearer, an optical imager for shaping light beams corresponding to an image emitted by a beam generator device and for directing them towards each of the wearer's eyes so as to enable information content contained in a virtual image to be viewed, the display being associated with a pair of eyeglasses having two lenses supported by a frame. According to the invention, the method consists in moving at least one said lens (10A, 10B) relative to said frame (11) with three degrees of freedom, in order to obtain superposition of the two virtual images, each said imager being contained in said lens (10A, 10B) of said pair of eyeglasses.

  • Method and a system for processing measurement signals for characterizing the state of occupancy of a motor vehicle seat
    Publication number: 20050154516
    Abstract: A method of processing measurement signals output from a detection array comprising at least one sensor, for characterizing the state of occupancy of a motor vehicle seat. The method includes a classification operation for classifying the state of occupancy of the seat. The method also includes a correction operation, during which the measurement signal output by the detection array is corrected at least in part for environmental drift relating to temperature and to humidity prior to being analyzed in the classification operation for classifying the state of occupancy.
