Filed: 2000-01-20
Abstract: A molecular computer is formed by establishing arrays of spaced-apart input (12) and output pins (14) on opposing sides of a (10), injecting moleware (16) in solution into the containment and then allowing the moleware to bridge the input and output pins. Moleware includes molecular alligator clip-bearing 2-, 3-, and molecular 4-, or multi-terminal wires (30, 36, 40, respectively), carbon nanotube wires (80), molecular resonant tunneling diodes (32, 38), molecular switches (90), molecular controllers (42) that can be modulated via external electrical or magnetic fields, massive interconnect stations (44) based on single nanometer-sized particles, and dynamic and static random access memory (DRAM  and SRAM) components composed of molecular controller/nanoparticle or fullerene hybrids (46). The current-voltage characteristics that result from the bridging between input and output arrays can be ascertained using another computer to identify the bundles of inputs and corresponding outputs that provide a truth table for the specific functions of the computer.

Title: A film for medical use, consisting of linear block polymers of polyurethane and a method for the production of such a film
Inventor: GISSELFALT KATRIN
IPC: C08J9/28
Filed: 2000-01-18
Abstract: The present invention concerns a film for medical use consisting of linear block polymers of polyurethane urea containing hydrolysable ester groups.  These ester groups must be so spaced from each other on the carbon chain that on their hydrolysis such small fragments are formed that they can be secreted from a human body or that of a mammal. The film is characterised in that it is porous with an average pore size of up to 600 µm. The invention also includes a procedure for the production of the film in which a solution of the film-forming polymers with a concentration of 5-30 % is applied as a thin layer on a surface after which the solvent is evaporated and/or the layer is treated with a polymer-precipitating agent.
Patent CA-2367009-A1 (CA)
Inventor: DEWEY CHARLES HENRY
IPC: E21B7/06
Filed: 2000-03-24
Abstract: This invention relates to a whipstock casing milling system and, more particularly, to such a system in which a window mill is secured to a whipstock so that the system may be run into a well, set and operated to open a window in a casing during a single trip. The milling system of the present invention comprises a protrusion (B) provided on the whipface of the whipstock wherein the protrusion (B) forms an extension of a relatively steep ramp surface (45) of the whipface so as to reduce damage to said surface (45) at a juncture (A) of said surface (45) with a relatively shallow ramp surface or parallel surface (46) during use of the system. The protrusion (B) thereby avoids an undercutting of a casing and a thinning of the whipstock.

Title: System and method of creating subscriber services in an ip-based telecommunications network
Inventor: PAGUREK BERNARD
IPC: G06F17/30
Filed: 2000-08-15
Abstract: A system and method of creating subscriber services in an Internet Protocol (IP)-based telecommunications network. A service creation architecture includes a Service Component Creator (SCC (19)) that creates service proxy objects, and posts them on a Lookup Service (LUS (18)). The LUS is accessible through the Internet (24) by Enterprise Service Creators (ESCs (21)). The ESCs download the posted service proxy objects from the LUS, and customize the downloaded objects to create customized services for enterprise users. The ESCs upload the customized service proxy objects to an Enterprise LUS (23), and the Enterprise LUS downloads the customized service proxy objects to a Service Management Unit (SMU (25, 26)) serving the end user. A gatekeeper (12, 13) serving the end users utilizes the service proxy code downloaded to the SMU to determine the location of a Service Implementation Repository (SIR  (27)) that stores actual service code for implementing the customized service.  The gatekeeper then downloads the actual service code from the SIR, constructs a customized User Service Agent (USA) that includes the actual service code, and sends the customized USA to an agency (mobile agent platform) at the user's terminal.

Inventor: JONES HERBERT R JR
IPC: G06F3/01
Filed: 2000-10-31
Abstract: L'invention concerne des procédés et un appareil de poursuite de position/orientation dans un volume limité. Ces procédés et cet appareil font appel à au moins un détecteur fixe, appelé "détecteur témoin", ayant une position et une orientation fixes près ou à l'intérieur du volume afin de représenter la distorsion électromagnétique. Un ou plusieurs détecteurs-sonde sont placés sur un objet devant être poursuivi à l'intérieur du volume et la sortie de chaque détecteur témoin sert à calculer les paramètres d'une source électromagnétique efficace non réelle. Les paramètres de la source efficace servent d'entrées pour le calcul de la position et de l'orientation mesurées par chaque détecteur-sonde, comme si l'objet se trouvait dans le champ électromagnétique non distorsionné produit par la source ou les sources efficaces. Outre les suiveurs pour les visualisations de casque dans des avions, des chars d'assaut et des véhicules blindés, l'invention est utile pour tout système de poursuite électromagnétique susceptible d'être soumis à une distorsion ou à une interférence électromagnétique. Ces domaines d'application comprennent des systèmes électromagnétiques de détection de mouvement ainsi que des système et des instruments médicaux, entre autres systèmes.
