Title: Security link management in dynamic networks
Inventor: MOORE TIMOTHY M
IPC: G06F15/00
Filed: 2001-02-23
Abstract: A method for setting up and managing secure data/audio/video links with secu re key exchanges, authentication and authorization is described. An embodiment of the invention enables establishment of a secure link with limited privileges  using the machine identifier of a trusted machine. This is particularly usef ul if the user of the machine does not have a user identifying information suitable for authentication. Furthermore, the presentation of a default user  identifying information by a user advantageously initiates intervention by a  system administrator instead of a blanket denial. This decentralized procedu re allows new users access to the network without having to physically access a  centralized facility to present their credentials. Another embodiment of the  invention enables a remote user to connect to a secure network with limited privileges.

Title: System and method for selecting and reselecting antenna direction at a transceiver
Inventor: MANTHA RAMESH
IPC: H04B1/38
Filed: 2003-03-10
Abstract: A method and system for selecting and reselecting an antenna direction for an antenna capable of transmitting signals in one of at least two selectable directions.  The average received signal-to-interference ratio is used to initially select the antenna direction. Thereafter the average received signal-to-interference ratio is monitored and the antenna direction reselected when the average received signal-to-interference ratio rises too far below the average received signal-to-interference ratio used to initially select the antenna direction for too long too often and if the antenna is not then required for a transmission that cannot be interrupted. If the average received signal-to-interference ratio drops significantly below the level used to initially select the antenna direction, then that level is reset downward. Reselection, if commenced, is repeated periodically until the antenna is required for transmission of a signal.

Title: Method for viewing tumor tissue located within a body cavity
Inventor: LUIKEN GEORGE A
IPC: A61B10/00
Filed: 2002-04-04
Abstract: Methods are provided for in vivo detection of diseased tissue in a subject, such as tumor tissue located in a body opening, by administering to the subject a biologically compatible fluorescing targeting construct that binds to or is specifically taken up by the diseased tissue. The observer directly views fluorescence emanating from the fluorescing targeting construct bound to or taken up by the diseased tissue upon irradiation of the targeting construct with excitation light having at least one wavelength in the range from 401 nm to about 495 nm, but preferably lacking light having a wavelength above about 500 nm, so as to determine the location and/or surface area of the diseased tissue in the subject. Since excitation wavelength does not penetrate through tissue, as is the practice in near IR diagnostics, the diseased or abnormal tissue is exposed to the excitation light either surgically or by means of an endoscopic device. Preferably a filter is used to filter out any wavelengths in the excitation light greater than about 500 nm.

Patent CA-2445497-A1 (CA)
Inventor: CHEN QINGYUAN
IPC: G05B17/02
Filed: 2002-06-24
Abstract: La présente invention propose une amélioration de deux approches classiques et inappropriées concernant le rapport concentration-densité. La première stipule que le soluté est complètement insoluble dans le solvant, et la seconde se base sur un soluté soluble. La présente invention concerne un modèle concentration-densité. Ce modèle permet de déterminer de manière théorique le rapport concentration-densité pour un mélange solide/liquide (sable/eau) ou liquide/liquide (CMC/eau) à multiples composants. Le modèle concentration-densité présente un nouveau concept connu sous le nom de coefficient de volume d'addition (AVC) (Fig. 1). Ce concept compense le fait que le volume net d'un mélange n'est pas toujours égal à la somme des volumes de chaque composant. Ce modèle concentration-densité amélioré permet d'utiliser dans des installations de traitement de fluide un procédé permettant de déterminer avec précision la concentration d'un volume en ligne à l'aide d'instruments de mesure de densité de courant.
