Greg Cardell - La Canada CA, US
International Classification:
G06F 13/36
US Classification:
710306000
Abstract:
A translation device between client-server computer networks and the General Purpose Instrumentation Bus (GPIB). Methods for Write, Read, and Command transactions to conduct data transfer between client-server computer networks and GPIB. Separate data channels and a single control channel are utilized. No specialized driver software is required.

International Classification:
G02B 626
US Classification:
385 14, 385132, 385 8, 385145, 385126
Abstract:
A structure for effecting a transition from a passive waveguide to an active waveguide or from an active waveguide to a passive waveguide of the present invention. The inventive device comprises a first cladding; a first core disposed within the first cladding; and a ground plane disposed over the first cladding and the core. A second cladding is disposed on the ground plane. A second core is disposed on the second cladding. A third cladding is disposed on the second cladding and the second core and an electrode is disposed on top of the third cladding. The inventive structure enables the construction of a novel an advantageous switch comprising an input port; an output port; and plural waveguides disposed between the input port and the output port. Each waveguide includes a first cladding; a first core disposed within the first cladding; and a ground plane disposed over the first cladding and the core. A second cladding is disposed on the ground plane.
