Method And Apparatus For Routing Data Through A Computer Network
view source -
US Patent:20020161929, Oct 31, 2002
-
Filed:Aug 31, 2001
-
Appl. No.:09/945577
-
Inventors:Donald Longerbeam - Roseville CA, US
Keith Hoek - Wheatland CA, US
Kelly Hall - Davis CA, US -
International Classification:G06F015/16
-
US Classification:709/250000, 710/314000
-
Abstract:The present invention relates to an improved method and apparatus for routing data and, more particularly, to a novel backplane for use in a data routing device, the backplane being an active backplane employing a PCI-PCI bridge interface chip and a bus operating at up to 64-bit and 66 MHz frequency. The present invention is also directed to a data routing device employing such a novel passive backplane.

Apparatus For Projecting An Image Having A Convoluted Focal Plane

US Patent:42170400, Aug 12, 1980
-
Filed:Apr 3, 1978
-
Appl. No.:5/892698
-
Inventors:Donald A. Longerbeam - San Mateo CA
-
International Classification:G03B 2100
-
US Classification:353 46
-
Abstract:A light source focuses light on a revolving, apertured color disc. The portion of the light passing through the moving colored apertures is refracted by a projection lens into a small beam. The beam passes through the peripheral area of two large convex lenses sequentially positioned in the projection path. The optical properties of the two lenses combine to define distant focal surface. Each of the convex lenses has smooth optical irregularities randomly formed on each surface thereof for generating convolutions in the distant focal surface. The two lenses rotate slowly in opposite directions causing a smooth animation of the convolutions on the focal surface. The lens rotation continuously introduces new combinations of optical irregularities into the projection path each of which establishes unique and slowly changing convolution arrangements on the focal surface. The image is viewed on a reflective surface positioned proximate the distant focal surface. A multicolored light source may be employed in place of the colored disc.
