  • Lenticular device for an autostereoscopic display apparratus and method of producing the same
    Patent number: 10416467
    Abstract: A method of producing a lenticular device for an autostereoscopic display apparatus includes providing a substrate having a surface which corresponds in shape to a desired surface profile for the array of lenticular elements, and providing an optical layer mixture of an optically birefringent material and a polymer precursor over the substrate surface. The optical layer is exposed to a stimulus for polymerizing the polymer precursor to have at least a polymer surface layer, thereby enclosing the material between the polymerized material and the surface to define lenticular elements. This method allows a simple polymerization process, forming a single layer, to complete the LC cell formation in the desired lenticular array shape.

  • System for obtaining assistance in operating an apparatus
    Patent number: 6397187
    Abstract: The invention relates to a system for obtaining assistance in operating an apparatus. A television receiver is provided with a microphone and a dedicated operator call button and connected to a communication network. When a user presses the button, a connection is established to a help desk operator, enabling the user and the operator to speak to each other. The operator can make the television receiver show a picture of the control panel of the apparatus for which assistance is requested, and generate control signals for visualizing operations on the control panel. An animated image of the operator is shown on the television receiver, controlled by the sound level of the operator's voice, in order to elucidate the source of the voice speaking to the user.
