IPC: G06F17/30
Filed: 2000-10-31
Abstract: A verbal classification system and method for the efficient sending and receiving of desired information is described. Web-site proprietors (314) an d Internet marketers provide a host server (320) with descriptive data about their web-sites and messages (336) according to a predefined verbal hierarch y of nouns, verbs and modifiers. An Internet user creates a role or roles (340 ) that describes desired information according to the same predefined verbal hierarchy of nouns, verbs, and modifiers and transmits that role (340) to th e host server (320), provides the Internet user with desired web-site addresse s (336) and message by matching the role (338) to web-site and message descriptive data (336). The Internet user may access a web-site using one or  more roles (340) and the web-site may provide the user with custom content b y matching content (338) to the Internet user's role and roles (340). The host  server (320) collects role information (340) from Internet users and web-sit es to generate marketing and demographics data (346) about Internet users and w eb- sites (328). Internet user privacy is protected because role data (340) is encrypted and contains no personal identification information (348).

Title: Inflatable fabric with peel seams
Inventor: KESHAVARAJ RAMESH
IPC: B60R21/232
Filed: 2000-11-15
Abstract: The invention relates to inflatable fabrics which comprise two separated and distinct fabric layers in discrete areas of such fabrics as well as connecting seam-producing materials to which such fabric layers are simultaneously attached. The resultant inflatable fabric composite thus includes inflatable areas separated, at least partially, by seamed barrier areas. This configuration will form "pillowed" structures within the target fabric upon inflation. Such connecting seam-producing materials are incorporated within the two-layer structure as peel seams in relation with the individual fabric layers. Upon inflation, the seams then act as shear seams which greatly increases the overall strength of the two-layer inflatable fabric. These shear seams thus provide a relatively effective manner of reducing air permeability within the entire fabric article. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary. In particular, the inventive fabric may be incorporated within an airbag cushion.

Abstract: A system to provide mechanical energy to well-head equipment by directing pressurized gas existing in nearby pipelines to an engine. The engine is a linearly reciprocating piston in a closed cylinder driven by pressure differentials between the gas on either side of its piston, the differential being controlled by a switching valve which directs higher and lower pressured gas to the appropriate side of the piston, and which recirculates spent gas from the lower pressure side of the piston back to the pipeline. The system is a closed system, and avoids venting or flaring gas used in the engine.

Title: Method and system for synchronizing audio and visual presentation in a multi-modal content renderer
Inventor: BROCIOUS LARRY A
IPC: G06F3/0485
Filed: 2001-09-19
Abstract: A system and method for a multi-modal browser/renderer that simultaneously renders content visually and verbally in a synchronized manner are provided without having the server applications change. The system and method receives a document via a computer network, parses the text in the document, provides an audible component associated with the text, simultaneously transmits to output the text and the audible component. The desired behavior for the renderer is that when some section of that content is being heard by the user, that section is visible on the screen and, furthermore, the specific visual content being audibly rendered is somehow highlighted visually. In addition, the invention also reacts to input from either the visual component or the aural component. The invention also allows any application or server to be accessible to someone via audio instead of visual means by having the browser handle the Embedded Browser Markup Language (EBML) disclosed herein so that it is audibly read to the user. Existing EBML statements can also be combined so that what is audibly read to the user is related to, but not identical to, the EBML text. The present invention also solves the problem of synchronizing audio and visual presentation of existing content via markup language changes rather than by application code changes.
