Patent CA-2446842-A1 (CA)
Title: Synthetic doppler system and method for locating cooperative transceivers
Inventor: WIGHT JAMES S
IPC: H04Q7/36
Filed: 2003-10-27
Abstract: A system and a method of locating a co-operative transceiver in an indoor location by setting up multiple transmitting beacons outside of a building in which the transceiver is located. Information at the transceiver, such as time-of arrival (TOA) or time-difference-of arrival (TDOA) of the first-to-arrive signals originating from the external beacons, is relayed back to a processing centre. The angle-of-transmission (AOT) is then determined for the first-to-arrive signals, the only ones with a potential for line-of-sight signals, as well as any arriving reflected signals.  Synthetic Doppler, by revolving the transmitting antenna, is used to distinguish between a line-of-sight received signal in order to accurately determine the location of the transceiver.

Title: A cell therapy method for the treatment of tumors
Inventor: LETURCQ DIDIER J
IPC: A61K35/14
Filed: 2003-11-07
Abstract: T cell responses are often diminished in humans with a compromised immune system. We have developed a method to isolate, stimulate and expand naive cytotoxic T  lymphocyte precursors (CTLp) to antigen-specific effectors, capable of lysing tumor cells in vivo. This ex vivo protocol produces fully functional effectors. Artificial antigen presenting cells (AAPCs; Drosophila metanogaster) transfected with human HLA lass I and defined accessory molecules, are used to stimulate CD8+ T cells from both normal donors and cancer patients. The class I molecules expressed to a high density on the surface of the Drosophila cells are empty, allowing for,efficient loading of multiple peptides that results in ,the generation of polyclonal responses recognizing tumor cells endogenously expressing the specific peptides. The responses generated are robust, antigen-specific and reproducible if the peptide epitope is a defined immunogen. This artificial antigen expression system can be adapted to treat most cancers in a significant majority of the population.

Title: Joint de verrouillage de labyrinthe pour garniture definie hydrostatiquement
Inventor: WELCH EDWARD W JR
IPC: E21B33/1295
Filed: 2002-07-19
Abstract: L'invention concerne une garniture définie hydrostatiquement. Le piston de commande (18) est bloqué par un manchon de blocage (32) et un agencement taquet de blocage (48). Lorsque la profondeur souhaitée est atteinte, la pression du puits rompt un disque de rupture (42) afin de permettre à la pression hydrostatique d'agir sur un côté du manchon de blocage. L'autre côté du manchon de blocage est exposé à une chambre (36) sous pression atmosphérique ou sous faible pression. Le mouvement du manchon de blocage libère le taquet de blocage permettant au piston de se déplacer pour fixer la garniture. Le manchon de blocage présente un joint labyrinthe L de manière qu'une fuite inférieure à un niveau prédéterminé ne va pas actionner de manière prématurée le blocage du piston ni fixer prématurément la garniture. Une grande variété de motifs font également l'objet de cette invention.

Title: Eliminateur de signaux communs d'une source stereo
Inventor: COTE RICHARD
IPC: H04S3/00
Filed: 2004-02-10
Abstract: Afin d'accroître le potentiel de stéréophonie d'une source stéréo ordinaire, un dispositif (20) élimine les signaux communs d'une source stéréo. Le dispositif s'installe en relation avec quatre haut-parleurs dont deux primaires (38,40) et deux secondaires (42,44) et il comprend une entrée stéréo (34,36) et un circuit électrique reliant les deux haut-parleurs secondaires. Les haut-parleurs primaires reproduisent les signaux stéréo non altérés et les haut-parleurs secondaires reproduisent les signaux altérés où le circuit a éliminé les signaux communs aux deux canaux de la source stéréo primaire. Étant donné que toutes les composantes 'mono' du son ont été éliminées aux sorties secondaires, nous obtenons ainsi une source 'purement stéréo'. Un canal supplémentaire (45) peut être rajouté afin de reproduire la composante commune de la source stéréo.

The device includes a flexible substantially rectangular body member having a plurality of protrusions extending outwardly and inwardly therefrom. A flexible bungee type cord is attached to each end of the body member. The device is operated by placing the body member on the tire tread surface, pulling the bungee type cord around the inner side of the tire such that the bungee type cord rests on the axle on the inner tire surface, and hooking the bungee type cord together to itself at the outer tire surface. The inward protrusions of the body member project into the spaces in the tire tread and are sized so as to be passively held there further securing the device on the tire. The outward protrusions of the body member provide additional traction to the tire tread when the tire rotates in either direction, and may be arranged in a standard tractor tread pattern to maximize traction.

Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based upon the identification of genes that are amplified in the genome of tumor cells. Such gene amplification is expected to be associated with the overexpression of the gene product as compared to normal cells of the same tissue type and contribute to tumorigenesis.  Accordingly, the proteins encoded by the amplified genes are believed to be useful targets for the diagnosis and/or treatment (including prevention) of certain cancers, and may act as predictors of the prognosis of tumor treatment. The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
