Patents by Inventor Johan Stiens

Johan Stiens 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).

  • Low power line switching circuit, device and method
    Patent number: 6211701
    Abstract: A drive circuit comprises an output terminal for connection to a signal line 1002. An inductor 1012 is coupled between the signal line 1002 and a reference voltage node 1010. A switch 1008 is coupled between the signal line 1002 and the reference voltage node 1010. When the switch 1008 is closed, the inductor 1012 is coupled between the reference voltage node 1010 and the signal line 1002. When the switch is open, the inductor 1012 is not coupled between the reference voltage node 1010 and the signal line 1002.

  • Transmission-mode optical coupling mechanism and method of manufacturing the same
    Patent number: 6031951
    Abstract: For use over a substrate having a substrate refractive index, a diffraction grating for, and method of, converting normally incident light into horizontally propagating light inside the substrate and an optical device employing the diffraction grating or method. In one embodiment, the diffraction grating includes: (1) a first volume of a first material having a first refractive index higher than said substrate refractive index, and (2) a second volume of a second material having a second refractive index lower than the substrate refractive index, the second volume being less than the first volume.
