Patent CA-2167427-A1 (CA)
Inventor: HIRSHFIELD EDWARD
IPC: H04B7/185
Filed: 1996-01-17
Abstract: An antenna structure (10) that includes a plurality of transmit linear elements (22a-22d) arranged parallel to one another and a plurality of receive linear elements (24a-24d) also arranged parallel to one another. Individual ones of the plurality of transmit linear elements are spaced apart from one another and have one of the plurality of receive linear elements disposed therebetween. A width of each of the plurality of transmit linear elements and the plurality of receive linear elements varies periodically along  a  length  of  the linear  element,  thereby  also periodically   impedance   modulating   each   element. Furthermore, a narrowest width portion of a transmit linear element is disposed adjacent to a widest width portion of an adjacently disposed receive linear element, and vice versa, thereby minimizing coupling between the elements. The  transmit  amplifiers  (16a,  16b)  and  the  receive amplifiers (30a, 30b) are located at opposite ends of an antenna stalk body (36) such that the transmit amplifiers and receive amplifiers are intimately associated with their respective antenna elements, thereby further minimizing losses. Also, because the transmit amplifiers may generate considerable heat,  the construction technique thermally isolates the lower power receive amplifiers from the higher power transmit amplifiers. Also, the transmit amplifiers are preferably located at the end of the antenna stalk that is nearest to the user transceiver,  thereby providing improved heat sinking.

Title: Aspartoacylase gene, protein, and methods of screening for mutations associated with canavan disease
Inventor: MATALON REUBEN
IPC: C12Q1/6883
Filed: 1994-07-05
Abstract: Canavan disease, an autosomal recessive leukodystrophy, is caused by deficiency of aspartoacylase and accumulation of N-acetylaspartic acid in brain. Human aspartoacylase (ASP) cDNA spanning 1,435 bp has been cloned and expressed in E. coli. A base change, a854>c, has been found in 85% of the 34 Canavan alleles tested so far, which results in a missense glu285>ala mutation that is predicted to be part of the catalytic domain of aspartoacylase. Several additional mutations have also been identified. The invention therefore provides nucleic acid sequences, genes, polypeptides, antibodies, vectors containing the gene, host cells transformed with vectors containing the gene, animal models for the disease, methods for expressing the polypeptide, genetic screening methods and kits, diagnostic methods and kits, methods of treating Canavan disease and methods of genetic therapy for the disease.

Inventor: POHTO GERALD R
IPC: C25D17/12
Filed: 1996-05-09
Abstract: An electrode assembly which will find use such as in electroplating, is made from a hollow and thin walled, elongate and deflectable outer metal electrode member.  This member is usually rounded, e.g., typically circular, in cross-section and has major inner and outer faces.  Representative of this outer member would be a titanium tube.  The electrode assembly also has a removable and elongate, inner metal electrical current distributor member. This inner current distributor member will typically be rectangular in cross-section. Representative of this inner member is a rectangular copper bar.  As assembled, this typical assembly can have the edges on the outer face of the copper bar engage the inner face of the titanium tube.  In putting together this particular assembly, the hollow tube is compressed, such as from circular to elliptical shape. The copper bar current distributor is inserted into this misshapen tube.  When the pressure on the electrode member tube is released, the resulting spring reaction of the tube flexes it back onto the corners of the copper bar.  These corners bite into the interior face of the titanium tube.  This procedure is reversible when the electrode assembly is in need of refurbishing.

Title: Videophone system
Inventor: SPRUCK MANFRED
IPC: H04N5/238
Filed: 1996-10-25
Abstract: In the case of a videophone system, it is known to vary the amount of light falling onto the target by a shutter, which is electronically controlled for a greater or lesser length during a short exposure time, rather than by means of a controlled mechanical aperture. It has been found that interference occurred when data reduction was used for the signal to be transmitted. In particular, macroblocks were also formed when no difference signal was present. The object is to develop such a videophone system such that interference of this type is avoided in the case of data reduction. The control circuit for the exposure time and the mains power supply which produces the ambient light are coupled by means of a PLL circuit in such a manner that the exposure time always occurs at the same phase of the mains voltage. In particular for a videophone system having an electronically controlled shutter and data reduction for the transmission.
