Patent CA-2266520-A1 (CA)
Inventor: FRICKE J ROBERT
IPC: G01M1/32
Filed: 1997-09-17
Abstract: The low-density granular fill has a specific gravity less than 1.5, placed in hollow cavities built into turbomachinery blades, vanes, and shafts, and provides effective damping at lower frequencies than conventional passive damping treatment due to its low bulk compressional sound speed. Selected materials used for the granular fill treatment are chosen for specific turbomachinery needs, including temperature of operation. Rotation speed is also a factor because it induces on the granular material an apparent hydrostatic pressure associated with the centripetal acceleration, and sound speed in granular materials is a function of pressure raised to the power 1/n. Preferred designs for placement of low-density granular material in appendages and shafts are found using an iterative design tool based on the Direct Global Stiffness Matrix method.

Title: Methods for preventing graft rejection in transplantation and for producing a universal gene therapy host cell using lymphocyte activation (lag-3)
Inventor: BIFFONI MAURO
IPC: C12N15/11
Filed: 1996-11-29
Abstract: A method to prevent graft rejection of transplanted cells, tissues or organs without general immunosuppression is described. The method employs a newly discovered protein, LAG-3. When allogeneic or xenogeneic cells are engineered to express LAG-3 on their surface and transplanted, immune destruction of the implanted cell, tissue or organ is prevented, while the host's immune system remains functional. A particular application of this method allows the preparation of a universal gene therapy host cell expressing LAG-3 on its surface for protection from graft rejection by a host's immune system.

Patent CA-2281733-A1 (CA)
Title: Rake receiver for direct spreading cdma transmission
Inventor: SAWAHASHI MAMORU
IPC: H04B1/712
Filed: 1998-12-24
Abstract: A baseband spread modulation signal is input to a matched filter (131). The matched filter (131) despreads the spread modulation signal using the output of a spreading code replica generator (132).      The matched filter (131) outputs the despread signals at L timings. The output signals are multiplied by multipliers (201) by corresponding weighting factors output from a weighting factor controller. The multiplied outputs are demodulated by demodulators (202), and RAKE combined by an adder (118). A data decision section (203) generates from the RAKE combined signal a data decision signal. An error signal generating section (204), receiving the RAKE combined output and the data decision signal, obtains an error signal. The weighting factor controller (205), carrying out such control that minimizes the error signal using the error signal and the despread signals fed from the matched filter (131), determines the weighting factors, and the multipliers (201) multiply the outputs of the matched filter (131) by the weighting factors. This makes it possible to RAKE combine multipath signals with reducing the effect of signals consisting of only noise or interference components.

Patent CA-2286963-A1 (CA)
Inventor: WALKER MICHAEL
IPC: H04M1/58
Filed: 1999-10-20
Abstract: Undesired electric coupling between the transmitting path and the receiving path of a telecommunications system and acoustic coupling between the loudspeaker and the microphone in a telecommunications terminal give rise to echos which are to be eliminated by echo suppressors. To be able to adapt these echo suppressors to instantaneous transmission functions, it is necessary to determine a coupling factor and the echo delay time. An essential problem here consists in differentiating between echo and mixed signals produced by so-called double talk. In accordance with the invention, from the characteristic curve of the speech signal there are derived pulse sequences which are dependent upon the frequency but not the amplitude of the speech signal, so that in the case of a real echo, independently of the attenuation, identical pulse sequences occur in the case of the transmitted signal and, with a time shift, in the case of a received echo.      The correspondence between the pulse sequences of transmitted signal and received signal is an indication that the received signal is an echo of the transmitted signal.
