Patent CA-2314030-A1 (CA)
Inventor: SPIELMAN TIMOTHY G
IPC: G06Q10/08
Filed: 2000-07-13
Abstract: A system and method of processing an order for delivery of an item into a locked enclosure that may be opened by an entry code. Under the control of a client system an entry code to unlock the locked enclosure is obtained or generated. The entry code is sent to a server system as a part of the process of requesting delivery of the item into the locked enclosure. A component of the server system receives the code and transmits the code to a deliverer to enable the deliverer to deliver the item into the locked enclosure.
Patent CA-2314381-A1 (CA)
Title: Article having photocatalytic activity
Inventor: INOMATA HIROYUKI
IPC: B32B17/00
Filed: 2000-07-20
Abstract: A surface of a glass plate is coated with a first n-type semiconductor film which is a 50 nm-thick niobium oxide film as a primer layer. The primer layer is coated with a 250 nm-thick photocatalyst film comprising titanium oxide. Thus, an article having a photocatalytically active surface is obtained. The two coating films can be formed by sputtering.  The first n-type semiconductor film as the primer layer is selected so as to have a larger energy band gap than the titanium oxide. Due to this constitution, more holes are generated near the film surface. This article can be free from the problem of conventional titanium oxide films having photocatalytic activity that it is difficult to generate many surface holes contributing to photocatalytic activity, because electrons and holes generated by charge separation recombine within the film, making it impossible to effectively heighten catalytic activity.

Title: Clamped receiver array using coiled tubing conveyed packer elements
Inventor: PAULSSON BJORN N P
IPC: E21B47/01
Filed: 1999-03-08
Abstract: A clamped receiver array using coiled tubing conveyed packer elements is disclosed and described. The receiver array is adapted to be received within a borehole and is therefore particularly useful for borehole seismology. The receiver array has a plurality of receivers connected together by a signal cable. The receivers include sensors which can be 3-component geophones. The apparatus is further provided with a fluid conduit running essentially parallel to the signal cable, the fluid conduit having expansible sections located adjacent to the receivers. The expansible sections expand in response to an increase of fluid pressure within the fluid conduit, contacting the associated receiver and thereby pushing the receiver into a coupled or clamped contact with the casing in the wellbore. The expansible sections have a resilient rubber outer sleeve which fits over a structural tensile strength element which is configured to conduct fluid with the fluid conduit while also providing mechanical strength for the apparatus to be deployed within a wellbore.

Title: Method for the coding of picture signals
Inventor: HERPEL CARSTEN
IPC: H04N19/186
Filed: 1992-04-14
Abstract: A hybrid Discrete Cosine Transform (DCT) coder processes blocks of (e.g., 8X8) pixels from interlaced or progressive scanned image signals. Processing of image lines by the coder is modified in the presence of image motion to avoid switching between 8X8 and 2X(4X8) transformations. For motion, the lines of two vertically superimposed image blocks are rearranged to produce first and second modified blocks.      The modified first block contains pixels from lines in a first field, and the modified second block contains pixels from lines in an associated adjacent second field.

Patent CA-2331422-A1 (CA)
Inventor: DECKER THOMAS A
IPC: C09J7/30
Filed: 1999-04-22
Abstract: A self-wound, self-adhesive, resealable tamper-evident tape is provided. The tape is used to seal any container requiring a self-adhesive closure, such as bags or pouches, and provides clear visual evidence if the self-adhesive seal is peeled apart. The tape comprises a backing sheet, the upper surface of which is coated with a release layer, and the bottom surface with an adhesive.  The release layer is relatively non-adherent to the adhesive so that the tape may be wound or rolled up without a separating liner. A non-visible patterned varnish layer is applied to the adhesive to create a hard surface onto which a colored ink layer is subsequently applied. The colored ink layer breaks or chips when the self-adhesive seal is peeled apart and retains this appearance if the tape is reapplied to seal the container, thereby providing visible evidence of tampering.

Title: 2-stage fluidized bed type fine iron ore reducing apparatus, and reducing method using the apparatus
Inventor: LEE IL OCK
IPC: C21B13/14
Filed: 1999-06-21
Abstract: A 2-Stage fluidized bed type reducing apparatus and a reducing method for fine iron ore of a wide particle size distribution with increasing the reducing gas utilization degree are disclosed. Fine iron particles dropping through the holes of a gas distributor (102, 202) can be recycled into the fluidized bed type furnace, thereby preventing an impediment of the reducing gas flow due to abnormal defluidizing or channeling. A first fluidized bed type furnace (100) dries, pre-heats and pre-reduces the fine iron ore, and a second fluidized bed type furnace (200) finally reduces the pre-reduced iron ore. Downstream of the respective fuidized beds, there are installed intermediate hoppers (500, 600) and gas/solid sealing valves (501, 503, 601, 603). Thus the fine iron ore particles which drop through the holes of gas distributors (102, 202) during the abnormal operation are recycled to the furnaces (100, 200) Accordingly the gas flow is not impeded.

Abstract: A user sends a request signal to a delivery management server 60 by utilizing a mobile station 10 in response to a broadcast service provided by a broadcast station 70. The request signal includes a music song ID of music song data segments which the user wants to be delivered and also an address of the destination to which the music song data segments be delivered. Upon the receipt of the request signal, the delivery management server 60 returns, in the case of unpopular songs, the music song data segments and a decrypting key for decrypting the data segments, and on the other hand, it returns, in the case of popular songs, only the decrypting key to the mobile station 10 or a STB 40. The mobile station 10 or the STB 40 decodes, in the case of unpopular songs, the music song data segments received from the delivery management server 60 by utilizing the decrypting key therefor and on the other hand, it receives, in the case of popular songs, the music song data segments in the broadcast waves provided from the broadcast station 70 and then decrypts data segments by utilizing the decrypting key received from the delivery management server 60.

Abstract: A backlight apparatus has a collimating waveguide with a light input end (54), a top surface (58), a bottom surface (56), opposing sides (60), a far end opposite the light input end (62), and a total internal reflection critical angle for the material of the waveguide. A plurality of first facets (80) are formed in the bottom surface (56) distributed along the waveguide between the light input end (54) and the far end (62). Each of the first facets (80) has a first facet bottom surface (82) which converges toward the top surface in a direction away from the far end (62) relative to the top surface (58). A light scattering and reflective surface (344) is disposed adjacent the far end of the collimating waveguide. The first facet bottom surfaces (82) cause light rays entering the light input end to be totally internally reflected to the far end of the collimating waveguide wherein the scattering and reflective surface at the far end reflects and scatters light rays incident thereon back toward the light input end. The first facet bottom surfaces (82) then cause the light rays reflected from the far end (62) to exit the top surface (58). The first facet bottom surfaces (82) may be formed either as straight facets or as curved surface facets and may also be alternatively formed having a reflective material layer thereon.
