Title: Polynomial expansion multicast message distribution
Inventor: GILBERT TIMOTHY G
IPC: H04L12/18
Filed: 1997-06-23
Abstract: A polynomial expansion network of a plurality of nodes, each node capable of communicating with the other nodes through a communications system. The network has an originating node that sends a message for ultimate receipt by a subset of nodes in a polynomial expansion manner. The network also has a first and a second receiving node, each of which receives the message from the originating node. The first and second receiving nodes also receive a unique list of other nodes to which the message has not yet been sent. The polynomial expansion manner can be optimized such that each node sends the message to no more than a predetermined number of other nodes to which the message has not yet been sent, or such that, before each node receives the message, the message passes through no more than a predetermined number of other nodes.

Patent CA-2272686-A1 (CA)
Inventor: CHOW ALAN Y
IPC: H01L31/08
Filed: 1997-11-25
Abstract: An image processing system for capturing and compressing images into a digital format is disclosed. The system has an array of imaging pixel elements which consist of two photodiode detectors (Opsistor). One photodiode detector is a capture detector while the other detector is a reference detector. The capture detector has an anode electrically coupled to the cathode of the reference detector. The cathode of the capture detector is electrically coupled to the anode of the reference detector. An image may be compared to a reference image detected by the reference detector. Different levels of light between the captured image and the reference image change the electrical output of the opsistor. Image compression is facilitated since only pixel elements which change from frame to frame need be stored. Additionally, a processing and compression circuit may use column and row scans to eliminate unchanged pixels and store only pixels with different light levels between images.

Abstract: An Internet marketing method and game is designed for promoting access to the web site which hosts the game, and to keep potential consumers occupied on the web site for exposure to several different advertisements, or to a few advertisements repeatedly. The inventive game is centered around a "point and click" system in which a screen display is provided which includes a game image made up of a large number of individual pixels. A player is encouraged to randomly select a pixel or image area location on the game image which selected pixel or image area location is then compared to one or more stored prize winning pixel or image area locations. Players are encouraged to play the game as many times as they like, and with each play, one or more advertisements are displayed on the screen outside of the picture, and on losing response pages with each additional "play" of the game.
