Title: All optical switching routing system
Inventor: FERGUSON BRUCE A
IPC: H04B10/27
Filed: 2002-06-18
Abstract: PROBLEM TO BE SOLVED: To provide an optical switching device that routes an optical data packet by using an all optical architecture signal detection and switching system in an optical region. SOLUTION: The packet includes header bits 16, data bits 18, and a reset bit 24. The header bits identify the switch state for routing the data packet and the specific routing information for distinct portions of the data packet. The header bits are transmitted at an optical carrier frequency different from the carrier frequency of the data bits. The reset bit resets the switch element processor to enable it to process and route the next data packet. The frequency of a particular header bit affects the index of refraction of a Bragg grating of a detector 42 and the output of the detector is provided to a switch that determines the routing path of the packet. A return command resets the diffraction grating, so that it does not affect subsequent header bits.

Filed: 2002-06-19
Abstract: <P>PROBLEM TO BE SOLVED: To enable a user to easily discriminate the contents of a document when a page is scrolled and displayed independently of the sorts of images in an information display processor having a scroll display function.  <P>SOLUTION: When a page scroll instruction is received, steady liquid crystal (LC) driving voltage and a steady inverter brightness value are temporarily set to reduce image contrast and brightness until a new page image (state P302) is formed. After the new page image is formed, page feeding LC driving voltage and a page feeding inverter brightness value are set to increase the image contrast and the brightness (state P303). Then the image contrast and the brightness are almost continuously reduced to a user set value which is set before a scroll operation (state P304). When a page scroll instruction is received in scroll display, the steady LC driving voltage and steady inverter brightness value are set to reduce the image contrast and brightness (state P302) and similar processing as mentioned above is repeated.  <P>COPYRIGHT: (C)2004,JPO
