Patent CA-2287137-C (CA)
Title: Polarization insensitive grating in a planar channel optical waveguide and method to achieve the same
Inventor: ALBERT JACQUES
IPC: G02B6/136
Filed: 1999-10-21
Granted: 2007-07-10
Abstract: A method is disclosed wherein optical structures such as Bragg gratings can be written into planar waveguides disposed on a substrate. By employing the method of this invention, a polarization insensitive device can be made. Such relatively thin planar waveguides disposed on a substrate are inherently polarization sensitive and the structure itself is birefringent. By writing structures in the waveguides or by simply writing a refractive index change in the waveguide by limiting the beam width at the waveguide layer to less than or equal to the thickness of the waveguiding layers on the substrate, in combination with conventional wider beam writing techniques, polarization sensitivity can be lessened or obviated.

Title: Method and system for tiered digital television terrestrial broadcasting services using multi-bit-stream frequency interleaved ofdm
Inventor: WU YIYAN
IPC: H04L27/26
Filed: 2001-04-12
Granted: 2009-06-30
Abstract: The present invention relates to a method and system for tiered digital broadcasting. A plurality of different bit streams representing digital data targeted for different services is received from a data source. Each bit-stream of the plurality of different bit-streams is modulated on a plurality of OFDM sub-carriers. Sub- carriers of different bit streams have different spectral efficiency. The parallel OFDM sub-carriers of each bit-stream are frequency interleaved with the parallel OFDM sub-carriers of the other bit streams of the plurality of different bit streams such that the parallel OFDM sub-carriers of each bit-stream are spread over an entire available frequency spectrum. The interleaved sub-carriers are transformed into time domain for providing a frequency interleaved OFDM signal. The OFDM signal is then upconverted to the frequency of a broadcasting channel and transmitted. The method and system according to the invention enables a broadcasting station to transmit multiple bit streams with different spectral efficiency using one RF channel allowing, for example, simultaneous transmission of digital TV for fixed and mobile recipients. Frequency interleaving of the OFDM sub-carriers of each of the multiple bit streams over the entire spectrum of a RF channel substantially reduces the risk that a signal is notched out by multipath distortion or fading.

Abstract: The present invention is a rack for stackable articles such as compact discs (CD's) video tapes, audio cassettes, trays, boxes and the like (here and after referred to as, the media), which also provides a convenient method to maintain accurate filing of same. The rack structure comprises opposing stanchions each containing a compressible element on their facing surfaces. Stanchions are spaced in accordance with the size of the particular media being racked and filed therein. What is new and novel about the present rack is that it is slotless in operation: each article is individually held or suspended by the side compressive force that the article generates on insertion between the stanchions This eliminates the need for slots, ledges, shelves or other space consuming supports. In the event of inserting new media, single, as well as groups of media can be freely slid longitudinally between the stanchions to a new position(s) in the rack to maintain a desired filing order. The present media rack will hold the media with the rack in any orientation: vertical; horizontal; upside down; while bouncing and moving, for example, in a car; and in a rotating filing wheel.

Abstract: A catalytic hydrocracking process wherein a first hydrocarbonaceous feedstock is contacted with a hydrogen and a metal promoted hydrocracking catalyst in a hydrocracking reaction zone at elevated temperature and pressure to obtain conversion to lower boiling hydrocarbons. The resulting hot, uncooled effluent from the hydrocracking reaction zone is hot hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrocracking zone to produce a first gaseous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream. At least a portion of the first liquid hydrocarbonaceous stream is preferably recycled to the hydrocracking reaction zone. A second hydrocarbonaceous feedstock having a boiling temperature range lower than that of the first hydrocarbonaceous feedstock is introduced into an upper end of the stripper to serve as reflux. The first gaseous hydrocarbonaceous stream is removed from the stripper and passed to a post- treat hydrogenation reaction zone to saturate aromatic compounds.
