Patent CA-2347198-C (CA)
Title: Scanned beam display with adjustable accommodation
Inventor: MELVILLE CHARLES D
IPC: G02F1/01
Filed: 1999-11-02
Granted: 2004-04-06
Abstract: A scanning beam display 10/50/150 controls the curvature of scanning light wave impinging on the eye to simulate image points of differing depth. To simulate an object at a far distance the generated light waves are flatter. To simulate closer objects, the light wave curvature increases. When changing the curvature of the light waves, the eye responds by altering its focus. The curvature of the light waves thus determines the apparent focal distance from the eye to the virtual object. To vary the curvature, either a variable focus lens 22/320 or a variable index of refraction device 22/330/350 is used.  Alternatively, a moving point source is used. The generated apparent distance of a virtual object is correlated to a detected distance in a background field of view. Intensity of the virtual object is correlated to detected intensity of background light.

Abstract: The present invention provides end-blocked nucleic acids, e.g., 2'-O-R, 2'-O-R-O-R, 3'-O-R, and 3'-O-R-O-R oligonucleotides, that exhibit significant low pH stability, nuclease resistance and optionally antibacterial properties. These low toxicity, highly specific, acid stable, end-blocked nucleic acids represent a novel and improved oligonucleotide structure for therapeutic treatments of diseases. The 3' and 5' acid stable, exonuclease resistant polymers of the invention are shown here to provide antibacterial effects when applied in vivo, e.g., applied topically to skin with actual sites of infection on dogs and humans.

Abstract: A system and method for enabling information providers to influence position for a search listing within a search result list generated by an Internet search engine. The network information provider may add, delete, or modify a search listing after logging via an authentication process (110). The information provider influences a position for a search listing in the provider's account by first selecting a search term relevant to the content of the web site. The network information provider enters the search term and the description into a search listing. The information provider influences the position for a search listing through a continuous online competitive bidding process (170). The bidding process occurs when the information provider enters a new bid amount for a search listing.  This system and method then compares this bid amount with all other bid amounts for the same search term, and generates a rank value for all search listings having that search term. The rank value generated by the bidding process determines where the information providers listing will appear on the search results list page that is generated in response to a query of the search term by a searcher located at a client computer on the network (170).

Abstract: Various embodiments of the invention provide increased speed and decreased computer processing for playing and navigating multimedia content by using two types of data objects for displaying the multimedia content. The first data object type includes rendered multimedia content data for a rendered cache, or rendering instructions for a paint stream cache or a layout cache. The second data object type provides semantic content corresponding to the rendered multimedia content.  The storage medium in which these two types of data objects are contained is referred to as a rendered cache. The very fast play of content stored in the rendered cache is due to the elimination of the steps of laying out the content, rendering the content, and generating the semantic representation of the content.

Abstract: A drilling assembly comprises an upper drill string and a lower drill string with a fluid passage extending through the upper drill string and the lower drill string for distributing fluid to a bottom hole assembly at the lower end of the lower drill string. The upper drill string has an upper end connectable to a drilling apparatus and fluid source and having a lower end with an attached casing expander unit that communicates the fluid passage of the upper drill string with the lower drill string. The lower drill string has an upper end formed from a casing string telescoped over the casing expander unit. A constriction connects the casing string with the rest of the lower drill string.
