Jacques Claude Thillays has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Display device for use with strong illumination
    Patent number: 4228490
    Abstract: An electroluminescent device includes at least one emissive diode emitting in the red. The emissive face of the diode is covered by a filter element which is substantially transparent in the red, and which has a light transmission coefficient in the blue which is significantly higher than its coefficient in the yellow and the green. The resulting device exhibits superior contrast in sunlight, and is thus particularly suitable for use in vehicle and aircraft dashboard displays.
    Type: Grant
    Filed: August 21, 1978
    Date of Patent: October 14, 1980
    Assignee: U.S. Philips Corporation
    Inventor: Jacques-Claude Thillays
  • Opto-electronic device having coupled emitter and receiver
    Patent number: 4118633
    Abstract: An opto-electronic coupler uses a light emitter and a photo-sensitive receiver, which are each associated with transparent bodies of revolution having convex and cylindrical portions.
    Type: Grant
    Filed: September 30, 1975
    Date of Patent: October 3, 1978
    Assignee: U.S. Philips Corporation
    Inventors: Lionel Guilleman, Jacques Claude Thillays
  • Light conductor in a signal isolator
    Patent number: 4100422
    Abstract: A conductor for the transport of light between a photo-emitter and a photosensitive receiver.Light conductor comprising a conductor element having total reflection the main face of which has substantially the shape of a hemispherical surface part and in which the emitter and the receiver are situated diametrically in the vicinity of the spherical surface part.Application especially to photocouplers having a semiconductor emitter and receiver.
    Type: Grant
    Filed: August 18, 1976
    Date of Patent: July 11, 1978
    Assignee: U.S. Philips Corporation
    Inventor: Jacques Claude Thillays
  • Opto-electronic photocoupling device and method of manufacturing same
    Patent number: 3976877
    Abstract: An opto-electronic photocoupling device in which the light emitter and receiver are coupled optically by a light conductor, and the conductor is constituted by a drop of a first transparent resin embedded in a second resin which is also transparent, the index of refraction of the first resin being higher than that of the second resin.
