  • Patent number: 10865590
    Abstract: A method for detecting the approach and/or contact of a user's hand close to a motor vehicle door handle. The handle including: an electrode having a capacitance, and a device for measuring the variation in capacitance, a low-frequency antenna situated close to the electrode, the emissions of the low-frequency antenna bringing about disturbances in the operation of the device for measuring the variation in the capacitance. The method proposes that a new adaptive approach detection threshold be calculated, depending on an average of the previous measured variations in the capacitance, calculated over a predetermined time interval, the measured variations being weighted by a factor depending on a difference between each measured variation and the average of the variations calculated previously over a previous predetermined time interval, the approach detection being confirmed if the measured variation is higher than the new adaptive threshold.

  • Patent number: 10852632
    Abstract: A transparent screen sheet that displays images projected from a front side of the transparent screen sheet and/or a rear side of the transparent screen sheet to a user on the front side, and causes the user on the front side to view a rear background behind the rear side. The transparent screen sheet includes an image display layer configured to display the images; and a resin film that holds the image display layer. A difference between a maximum value and a minimum value of retardations of the resin film measured by irradiating a main surface of the resin film with a light with a wavelength of 460 nm in a direction orthogonal to the main surface, within a region on the main surface that overlaps with the image display layer, is one fourth of the wavelength of the light or less.

  • Patent number: 10794114
    Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.
