Abstract: Damping of oscillations of the first bending mode of a wind turbine is performed means of one or more containers partly filled with a liquid for damping oscillations of the first natural bending frequency of the wind turbine. The damping means comprises a plurality of box shaped containers having a square cross section and being partly filled with liquid so as to provide a unidirectional damping with a logarithmic decrement of oscillation s of the first natural bending frequency of the wind turbine of at least 4-8%.  For off-shore wind turbines, the combined excitation of the wind and sea wav es requires more damping, the damping is preferably equivalent to a logarithmic  decrement of 10-15%. Furthermore, the invention relates to damping of oscillation of the second bending mode of a wind turbine and to the combined  damping of oscillations of the first as well as the second bending mode of t he wind turbine.

Patent CA-2384314-A1 (CA)
Inventor: KESHAVARAJ RAMESH
IPC: D06N3/14
Filed: 2000-09-12
Abstract: The present invention relates to an airbag fabric which is woven in such a manner as to possess a cover factor of less than about 1900 but which simultaneously, through the presence of a film (laminate) or coating, possesses an extremely low air permeability. The utilization of such a loosely constructed fabric within airbag cushions has heretofore not been possible, even with the application of standard airbag coatings (such as silicones) over the fabric surface since such coatings will not easily remain in contact over the loosely constructed fabric surface (i.e., the coating would leak through the fabric). The coupling of a low cover factor fabric with a laminate film (or with a coating wherein the cover factor is at least 1600), however, solves such a problem and permits the utilization of inexpensively produced woven fabrics within airbag applications.

Patent CA-2405017-A1 (CA)
Inventor: GOZDZ ANTONI S
IPC: H01M50/414
Filed: 2001-03-23
Abstract: A Li-ion battery cell comprising a polymeric matrix positive electrode layer member, a polymeric matrix negative electrode layer member, and an interposed microporous polyolefin separator layer member is laminated into a unitary, flexible cell structure by means of heat and pressure without necessity for applied interlayer adhesive. A primary plasticizer for the electrode member matrix polymer is included in the electrode layer compositions. During the lamination operation, which may be carried out at a moderate-temperature that does not compromise the thermal shutdown capability of the microporous separator, the plasticizer softens the polymer into a thermoplastic adhesive which forms an effective bond to the untreated polyolefin surface in the region of the electrode/separator interface. The plasticizer dissipates from the composition along with residual lamination heat or may be extracted with solvent or supercritical fluid, thereby enabling the electrode polymer alone to form a strong, permanent bond to the polyolefin separator member.

Title: Particulate material handling systems
Inventor: STENSON ARTHUR
IPC: B65G15/60
Filed: 2003-03-10
Abstract: The particulate material handling system comprises a tube, an endless belt that passes through the tube and returns outside of the tube, and a flighting that is suspended a predetermined distance from the belt through the entire length of the tube. The distance may be varied for the various materials being handled. An intake hopper is mounted at one end of the tube for receiving the material to be moved and a discharge spout is mounted at the other end of the tube for discharging the material from the tube. The endless belt and flighting are driven such that their speed may be varied and such that their relative speeds are synchronized to drive the material at substantially the same speed whether it is being carried by the belt or the flighting.   The combination of the belt and the flighting drives the material through the tube, minimizing damage to the material, which may be granular fertilizer, pulse crops, grains or other particulate material.

Patent CA-2424809-A1 (CA)
Inventor: PETERSON EUGENE HAROLD III
IPC: H04B17/00
Filed: 2003-04-09
Abstract: In accordance with the present invention, the quality of a received digital signal is determined by the receiver, such as by observing the received signal strength indication (RSSI) and/or the bit error rate (BER). When the quality drops below a first threshold, the receiver injects white noise into the reproduced audio signal to simulate the noise that typically accompanies an analog wireless signal of low quality. The amount of injected white noise may be increased as the signal quality continues to decrease beyond the first threshold. Preferably, at a second threshold at which the receiver can no longer reassemble the received signal, the white noise is muted to audibly indicate to the user that the signal has been lost.

Patent CA-2428628-A1 (CA)
Inventor: GARCIA JUAN MANUEL BUENO
IPC: A61B3/13
Filed: 2003-05-13
Abstract: The present invention provides a method and apparatus for improving the signal to noise ratio, the contrast and the resolution in images recorded using an optical imaging system which produces a spatially resolved image. The method is based on the incorporation of a polarimeter into the setup and polarization calculations to produce better images. After calculating the spatially resolved Mueller matrix of a sample, images for incident light with different states of polarization were reconstructed. In a shorter method, only a polarization generator is used and the first row of the Mueller matrix is calculated. In each method, both the best and the worst images were computed. In both reflection and transmission microscope and Macroscope and ophthalmoscope modes, the best images are better than any of the original images recorded. In contrast, the worst images are poorer. This technique is useful in different fields such as confocal microscopy, Macroscopy and retinal imaging.
