Patent CA-2437705-C (CA)
Title: Agile multi-beam free-space optical communication apparatus
Inventor: PRESLEY HARRY
IPC: H04B10/10
Filed: 2002-02-05
Granted: 2007-12-04
Abstract: An electronically agile multi-beam optical transceiver has a fist crossbar switch, that switches input signals to selected ones of a spatial array of light emitters. The light emitters supply modulated light beams to spatial locations of a telecentric lens, which geometrically transforms the beams along different divergence paths, in accordance with displacements from the lens axis of the light emitter elements within the spatial array. Light beams from remote sites incident on a divergence face of the telecentric lens are deflected to a photodetector array, outputs of which are coupled to a second crossbar switch. An auxiliary photodetector array monitors optical beams from one or more sites whose spatial locations are known, and supplies spatial error correction signals for real-time pointing and tracking and atmospheric correction.

Filed: 2002-08-02
Granted: 2014-09-16
Abstract: A screening method for identifying an individual having a pre-disposition towards having a cancer is disclosed, which screening method comprises the steps of : (a) obtaining a test sample comprising a nucleotide sequence comprised in a gene in a gene in a base excision repair (BER) pathway of the individual or an amino acid sequence of a polypeptide expressed thereby; and (b) comparing a region of the test sample sequence with the corresponding region of the wild type sequence, whereby a difference between the test sample sequence and the wild type sequence signifies that the individual is pre-disposed to having the cancer; and wherein the difference comprises a specified variation. The specified variation can be the known mutation in the human MYH protein, G382D-hMYH or a nucleotide sequence encoding it, or it can be one or more novel variations, namely, Y165C, E466X, and Y90X, or the respective corresponding nucleotide sequences. The method is particularly suitable for determining a pre-disposition towards bowel cancer.

Abstract: A bundling assembly for use with a strapping machine that is configured to position a strap material around a load and tension the strap material around the load includes first and second moving belts positioned at the strapping machine entrance in opposing relation to one another. The belts each have a paddle mounted thereto and define a pathway through the bundling assembly. A movable stop is positioned at the exit of the strapping machine and is movable between a stop position and a convey-position. The moving belts rotate to contact the paddles with the load, urging the load into the entrance of the strapping machine and into an area under the chute.  The belts stop rotation, thus stopping movement of the load upon contact of the load with the stop. The movable stop then moves to the convey position and the moving belts rotate such that the paddles move the load out of the exit of the strapping machine. A  stabilizing assembly applies a slight pressure on the load during the strapping cycle.

IPC: H04W24/00
Filed: 2002-08-19
Granted: 2015-02-24
Abstract: On embodiment of the system and method provides asymmetric adaptive modulation which allows uplink and downlink subframes (304, 302, respectively) of data to be transmitted between a base station (102) and a CPE (104) with different modulation schemes, thus increasing the efficiency of downlink transmissions while maintaining the stability of uplink transmissions. In systems with multiple CPEs, each CPE (104) and base station (102) pair can independently select their uplink and downlink modulation techniques. The system and method are also adaptive in that they adjust the modulation schemes based on, for example, signal to noise ratio measurements or bit error rate measurements.

Title: Expansive cell composition for electric rock destruction
Inventor: CHO YONG-SO
IPC: C06B33/12
Filed: 2005-01-14
Granted: 2010-03-09
Abstract: The present invention relates to an expansive cell composition for an electric rock destruction. The expansive cell composition is fabricated using metallic salt that is oxidation agent, metallic powder, and hydrocarbon compound. The composition is uniformly mixed at a certain composition ratio so that the composition is stably expanded by a high temperature heat and impact wave energy generated when a high current is fast discharged with respect to a metallic wire. A hybrid-oxidation and combustion reaction is obtained, in which a hybrid-oxidation and combustion reaction is performed, in which a flame oxidation reaction of metallic salt and metallic powder and a combustion oxidation reaction of a hydrocarbon compound by the flame oxidation reaction are mixed. The rocks are destructed by generating a vapor expansion force matching with a fracture ability class of rocks. Low noise and vibration are obtained when destructing rocks, and broken pieces of rocks do not fly away. Any change in quality does not occur in the composition according to the present invention.

Abstract: The invention relates to biomimetic artificial prostheses which are made from polyester, such as polyethylene terephthalate, and to a method for the biomimetic functionalization of said prostheses. The inventive method is characterized in that it comprises a step involving the grafting of biologically-active polymers or copolymers to the polyester surface of the aforementioned prostheses, said grafting step consisting of the peroxidation of the surface by means of ozonation followed by a step comprising the radical polymerization of a solution of at least one monomer. Said method also comprises an optional step consisting in impregnating the prostheses with type I and/or II collagen and/or fibronectins. The prostheses thus obtained enable a normal and uniform regrowth of the fibroblasts, thereby significantly improving the biological integration of such polyester prostheses.
