Patent CA-2281321-A1 (CA)
Title: Programmable network
Inventor: MIMURA ITARU
IPC: H04L12/70
Filed: 1999-09-03
Abstract: At each network node, a packet classification unit makes a judgement to transfer only a packet necessary to be processed by software to a packet processing program processor and transfer other packets directly to a routing processor. Processing history information indicating the process history executed at each network node on a network route is transferred to the other network nodes so that other network nodes can store the processing history information in respective processing history repository table. Each node refers to this table and further transfers only the packet necessary to be processed by software to the packet processing processor.
Patent CA-2281960-A1 (CA)
Inventor: DEANGELIS DOUGLAS J
IPC: H04N21/242
Filed: 1995-06-28
Abstract: The invention provides a system for recording and displaying a time sequential scene on a computer. The digital camera transmits a sequence of digital image frames to the timer representative of the image of a body passing a plane in space. Each frame represents a line object of the body, thus forming a fractional part of the scene. Once the frame reaches the image timer, it is digitally marked with a time reference and buffered into a block of information. The main control computer stores blocks of information from the image timer for a variety of processing and features available to the user. The invention also provides a selected memory, preferably a virtual memory subsystem, or hard-disc drive. Preferred constructions for adjusting camera pixel processing of light values, time-marking the images, creating colour palettes for interactive viewing of colour images, and video data coding to accommodate the high volume of line image data are described.
