Patent CA-2336564-A1 (CA)
Inventor: LIHME ALLAN OTTO FOG
IPC: G01N33/531
Filed: 1999-07-29
Abstract: L'invention se rapporte à la préparation de nouveaux conjugués réticulés, solubles dans l'eau et de complexes de conjugués réticulés, qui permettent d'accroître la capacité de détection de dispositifs d'analyse immunochimique, et notamment de dispositifs à flux latéraux. La préparation de ces conjugués repose sur un processus de "relargage" dans lequel un précipité réversible est formé à des concentrations salines lyotropiques supérieures à 1 M, ledit précipité coïncidant avec une réticulation de la charpente du conjugué intermédiaire soluble dans l'eau. Cette charpente, qui est composée de polysaccharides, en particulier de dextranes, est liée à un autre composant indicateur, tel qu'une teinture, qui produit une couleur, par l'intermédiaire d'un composant de liaison bifonctionnel, tel qu'une sulfone d'épichlorhydrine ou de vinyle, et éventuellement par l'intermédiaire d'un composant écarteur protéique tel que l'ovalbumine (OA) ou l'albumine sérique bovine (BSA). La réticulation des dextranes qui se produit par l'intermédiaire du composant de liaison, au cours du processus de "relargage", sert à produire, en présence de cibles adaptées telles que des anticorps ou des antigènes, des conjugués réticulés solubles dans l'eau et des complexes de conjugués réticulés.

Title: Ip mobility support using proxy mobile node registration
Inventor: WILLKIE JAMES J
IPC: H04L29/12
Filed: 1999-08-06
Abstract: A system and method for performing mobile node registration. The system comprises a terminal device (102) for transmitting packetized data, and a wireless communication device (104) coupled to said terminal device for monitoring said packetized data for an Internet Protocol (IP) address contained in an IP address request. The wireless communication device (104) initiates mobile node registration (512) using said IP address if said IP address request is for a static IP  address. The wireless communication device prevents (417) the terminal device from sending or receiving packetized data when initiating mobile node registration, and allows said terminal device to send and received packetized data upon completion of mobile node registration. As a result, the mobile node registration occurs transparently to the terminal device, obviating the need for the terminal device to have its own Mobile IP support.
Patent CA-2341942-A1 (CA)
Title: Continuous explosive charge assembly and method for loading same in an elongated cavity
Inventor: LOADER BRIAN F
IPC: F42D1/08
Filed: 2001-03-22
Abstract: A method and apparatus for placement of continuous pre-split, gel explosive in an elongated borehole or cavity. An anchor is attached to one end of a selected length of continuous -gel explosive. A suitable anchor is a flexible, plastic "pilgrim's hat" with a hole in the narrow, closed end. The size of the anchor depends on the width of the borehole; the flared skirt should be narrow enough to permit insertion of the anchor into the hole but wide enough to resist removal. One end of the explosive charge is pressed through the hole in the anchor. The remainder of the length of explosive is placed inside a tubular member, such as PVC pipe. The loaded pipe then is inserted into the borehole or cavity with the anchor leading. The pipe is used to push the anchor back into the hole to the desired depth. Then, the pipe is withdrawn.  The flexible skirt on the anchor engages the sidewall of the borehole and thus resists removal with the pipe. As the pipe is pulled out of the borehole, the explosive charge is left behind in a substantially linear arrangement. The explosive is detonated in a conventional manner.

Title: System and method for on-line payment
Inventor: LIN XIAODONG
IPC: G06Q20/02
Filed: 2001-05-15
Abstract: The present invention is a computer based system and method for on-line payment. A completion of a transaction between a shopper and a merchant is conducted through one or two trusted third parties. Both the shopper and merchant may use the same trusted third party or they may use their own trust third party. A trusted third party receives and sends messages to and from the shopper and merchant as well as a payment center. Each message provides encrypted information on the nature of the transaction. The trusted third party does not have the capability to decrypt detailed transaction information and thus is not privy to the nature of the transaction. Should a dispute arise, all parties involved have sufficient encrypted information in the messages to determine the nature of the transaction and the steps concluded.

Title: Medical system calibration with static metal compensation
Inventor: GOVARI ASSAF
IPC: A61B19/00
Filed: 2001-07-18
Abstract: A method for calibrating a medical system capable of generating a magnetic field for tracking a position of a medical device comprises various steps such as defining a mapping volume within the generated magnetic field and placing a metallic object within the mapping volume. A sensor is aligned at a first point within the mapping volume and the magnetic field at the first point is measured with the sensor to establish a first coordinate position (Xi, Yi, Zi). The sensor is moved to a next point (Xi + dx, Yi + dy, Zi + dz) along one coordinate axis by an added distance component (dx, dy, dz) and the magnetic field at the next point is measured to establish a next coordinate position. The magnetic field at an intermediate point between the first position and the next coordinate position is interpolated to establish an interpolated intermediate coordinate position. The position difference between the interpolated intermediate coordinate position and an actual intermediate coordinate position is determined and the position difference is compared to an error limit. (Xi, Yi, Zi) of the next point is set as (Xi = Xi + dx, Yi = Yi + dy, Zi = Zi + dz) if the position difference is within the error limit and the steps above are repeated along another coordinate axis. The added distance component (dx, dy, dz) is set by decreasing the value of the added distance component if the position difference is not within the error limit and the steps above are repeated along the same coordinate axis. A second embodiment utilizes an extrapolation of the magnetic field at the next point from the first position and calculation of the extrapolated next position. The difference between the calculated next position and the actual next position is then compared to an error limit. If the error limit is exceeded, the magnetic field of an intermediate point is measured and an intermediate position is determined along the same coordinate axis and the magnetic field of the next point is extrapolated from the intermediate position and the procedure is iterated until the error limit is met whereby the sensor is moved to a new point along another coordinate axis.

Title: Phase detector circuit
Inventor: TAKEO YASUHITO
IPC: H03L7/085
Filed: 2001-10-11
Abstract: To provide a phase detector circuit that prevents a significant loss of lock during input of CIDs (Consecutive Identical Digits) and have a high linearity of a phase to voltage conversion characteristic around phase-locked point in an operation of comparing phases of random NRZ signals in a phase. By using the phase detector circuit having a circuit configuration represented by a formula (1) or (2), for example, a circuit configuration shown in FIG. 11, a capability as the PLL circuit of preventing the significant loss of lock can be realized. In addition, since a duty cycle of a pulse appearing at an output terminal 3 of a multiplier circuit 62 approaches 50% as a phase-locked state is approached, a distortion in the phase to voltage conversion characteristic does not appear, and the high linearity of the phase to voltage conversion characteristic around phase-locked point can be realized.
