Title: Compensation de l'effet de kerr dans un gyroscope a fibre optique interferometrique
Inventor: BERGH RALPH A
IPC: G01C19/72
Filed: 1999-11-16
Abstract: Ce gyroscope à fibre optique interférométrique est pourvu d'un équipement électronique de compensation destiné à éliminer, quasiment, toute erreur de détection de vitesse de rotation due à l'effet de Kerr dans un gyroscope à fibre optique interférométrique, lequel effet de Kerr est provoqué par des différences d'intensité des faisceaux de sens inverse, l'un par rapport à l'autre. La compensation tient compte de la variation de l'intensité des faisceaux due à tous les écarts (ou à quelques uns) du rapport séparation de faisceau lumineux/température, à l'affaiblissement du bobinage à fibre optique causé par la température et par un long usage ainsi qu'à la diminution de l'intensité de la source lumineuse due au degré d'usure.

Title: Pipe connector and method for production thereof
Inventor: EHRKE DIETER
IPC: F16L19/028
Filed: 2000-11-29
Abstract: The invention relates to a pipe connector for a pressure-resistant, positive-fit, high pressure screwed joint, comprising a formed tube, a screw body or connector branch with a cone, which connects to a parallel axis drilling, with a radial end surface, a union nut, a sealing ring and a retaining ring, whereby the formed tube has a parallel axis end-piece with the same tube diameter and which corresponds to the depth of the tube seat base. The formed tube (3), with a pronounced bead (7), forms a mating face (9), with the cone surface (8) of the union nut (2), which leads to an abutment face (11), for a front face (12) of the retaining ring (6), essentially aligned with the tube axis (10). The retaining ring (6) has a radial ring surface (14), which, in the assembled state, contacts with the front face (16) of the cone of the connector branch (1) or screw body and thus permits a block assembly.

Abstract: A user of a remote computer accesses a target computer (e.g., the user's home PC) via the Internet. To initiate the protocol, the user launches an application which, via the Internet, sends a special request to the user's home e-mail address. If the home computer is not currently connected to the Internet, the user's Internet Service Provider (ISP) dials a telephone number for the home computer. The home computer automatically answers, and the ISP  sends authentication information to the computer to establish an Internet connection. With the connection established, an IP address is sent back to the user, which can then be used to invoke X-10 functions, telnet sessions, or other activities with the target computer.

Title: Method and apparatus for the correction of optical signal wave front distortion within a free-space optical communication system
Inventor: TYSON JOHN ANTHONY
IPC: H04B10/118
Filed: 2002-04-22
Abstract: A free space optical communication system is disclosed whereby the optics of a receive telescope are manipulated using adaptive optics to compensate for wave front distortion of a light beam transmitted by a transmit telescope. Wave front distortion is manifested at the receive telescope as a deviation from the normal, orthogonal orientation of the wave front of the transmitted light beam relative to its line of travel. This deviation may be detected, for example, by a wave front sensor, such as a Shack-Hartman sensor, which identifies the slope, or beam tilt, of discrete sections of the transmitted beam. The optics of the receive telescope can then be deformed in such a way as to cancel the wave front distortion and correspondingly reduce the resulting distortion of the received signal.

Abstract: An improved method of inducing whole-body hyperthermia and enhanced anti-tum or immune response through inoculation of a fever virus with nil mortality and subsequent injection of irradiated tumor cells derived from the patient. Thi s therapy will safely reduce the tumor burden by 90-99.9% by physical means (fever), before raising intererferon levels to over 250 times baseline. The Activated Lymphokine Killer cells produced by these high interferon levels a re capable of killing any cell expressing viral or tumor antigens, even those which had previously escaped immune surveillance. As a fin final step in the  process, a specific class of Cytotoxic T Lymphocytes programmed to destroy t he patient's own cancer cells will be produced by repeated inoculation of dendritic cells harvested from the patient. Through a combination of three methods never previously integrated into a single regimen, it is logical to state that this therapy has a high probability of completely eradicating cancer cells from the patient. In addition, this therapy provides for life- long immunity to the reoccurrence of the disease.
