Elmar Griese 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).

  • Position fixing in printed circuit boards
    Patent number: 7173192
    Abstract: The invention relates to a position-fixing arrangement for use in printed circuit boards, preferably for mechanically determining the position of optical couplers. According to the invention, hollow cylinders are contained in a printed circuit board, parallel to the surface of the same. Said hollow cylinders are opened with a slit that is cut in from the surface and the inner wall of the cylinders fixes positioning pins of the couplers in place. The invention also relates to a corresponding production process.

  • Simulation of electro-optical connections that takes spatial direction into consideration
    Patent number: 6865343
    Abstract: Simulation of the transmission behavior of opto-electronic connections, by which the transmitter or the receiver is represented by at least two optical outputs or inputs and the optical line is represented by corresponding multi-poles, considers the spatial distribution of the emitted or received optical radiation.

  • Coupling to waveguides that are embedded in printed circuit boards
    Publication number: 20040258345
    Abstract: According to the invention, waveguides are contained in an optical layer of a printed circuit board. Said waveguides are produced by an embossing process and emit light in a perpendicular manner by means of oblique, reflective ends. Mechanical guide marks are created using the embossing process for positioning couplers, said marks being preferably used as guide holes for MT pins.

  • Coupling for optical signals
    Publication number: 20030039431
    Abstract: A coupler for optical signals includes first and second coupling surfaces. Each of the first and second coupling surfaces has an optically-active region to map a light pattern according to a predetermined mapping function onto the other of the first and second coupling surfaces. Mechanical guide elements having positions on the coupler that are based on the predetermined mapping function.
