Patent CA-2241124-A1 (CA)
Inventor: BRANKOVIC VESELIN
IPC: H04B7/26
Filed: 1998-06-18
Abstract: According to the present invention a method and a receiver for high-frequency signals is provided. The receiver comprises a power divider (4) to divide a modulated RF  input signal in at least two branches. At least one delay line (5, 6) provides for a delay of the branches relatively to each other by a predetermined delay constant. A  calculation circuit (7, 8) calculates at least three power levels based on combinations (12, 13, 14) of the two branches of the input signal relatively delayed (5, 6) to each other. A  processing means (10) calculates the phase and the amplitude of a complex signal representing the relation between the two branches of the input signal relatively delayed to each other, on the basis of the said at least three power levels (8).   The invention therefore provides for a direct 6-port receiver based on non-coherent detection. The concept of the invention is inherently cheap and features high integration ability and low-cost processes. Ideally the whole RF front end can be placed on one chip.

Patent CA-2243859-A1 (CA)
Title: Multi-format audio/video production system
Inventor: SCHWAB BARRY H
IPC: H04N5/77
Filed: 1996-01-23
Abstract: A program input may be translated into any of various graphics or television formats, and stored as compressed images, using any of several commercially available methods. While being processed, the images (e.g. 180) may be re-sized (182, 184) to produce a desired aspect ratio or dimensions using conventional techniques, such as interpolation, and signals within the video data stream optionally may be used to control "pan-scan" operations at a receiving end, in case this end does not have the same aspect ratio as the source signal. Frame rate conversion to and from conventional formats is performed by using the techniques employed for welt known film-to-NTSC and film-to-PAL transfers, or by inter-frame interpolation. By judicious selection of the optimal digitizing parameters, the system allows a user to establish an inter-related family of aspect ratios, resolutions, and frame rates, and yet remain compatible with currently available and planned formats.

Title: Atm service scheduler using reverse-binary scattering and time-space mapping
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1998-12-02
Abstract: A method for scheduling low delay-jitter cell transmissions for multiple streams of Asynchronous Transfer Mode (ATM) traffic from a node is disclosed. Cells belonging to multiple streams of virtual circuits (VCs) and virtual paths (VPs) are stored in the node's memory. A link controller scans a time-space map to determine when a given stream will be sampled and its cells transmitted from the memory out over a link. The time-space map is comprised of time-slots whose spatial positions within the map correspond to times at which cells can be transmitted. A scattering technique, based on reverse-binary or other mapping schemes, ensures that each given stream occupies time-slots that are well-spaced within the time-space map. This ensures that cells belonging to a given stream are transmitted at well-spaced intervals of time.      The scheduler can provide each stream with a guaranteed real number of time-slots per time-space map, which allows for high resolution service rates to be supported without having to resort to using very large maps.

Patent CA-2261425-A1 (CA)
Inventor: WELLS DAVID L
IPC: C23C14/56
Filed: 1999-02-09
Abstract: A fixture apparatus for material deposition or processing on a long, flexible, nonplanar, filamentary substrate has a tubular member for holding the filamentary substrate rotatably disposed on a base. An opening is formed in the tubular member through which material is deposited on the surface of the filamentary substrate. Moveable tubes are each slidingly disposed in the tubular member on either side of the opening. The tubes and/or the tubular member hold the filamentary substrate on both sides of a deposition area on the substrate to maintain the straight configuration of the long, flexible, filamentary substrate. The tubes and/or tubular member also physically masks the filamentary substrate to prevent material deposition outside the deposition area on the substrate. The base has a circular path and a rotating member. A wheel is coupled to one side of the tubular member and is rotatably disposed on the circular path of the base. The other side of the tubular member is rotatable coupled to the rotating member of the base by a bearing. The rotating member causes the wheel to turn about a vertical axis in a circular path. The wheel is fixed to the tubular member causing the tubular member to rotate about a horizontal axis or longitudinal axis of the tubular member. As the rotating member turns and the wheel rolls, the tubular member the filamentary substrate is rotated about the two different axes to uniformly deposit material on the filament.

Title: Process and apparatus for the deposition of a viscous product on a substrate via a stencil
Inventor: BOURRIERES FRANCIS
IPC: B41M1/12
Filed: 1997-10-13
Abstract: A method and device for carrying out the deposition of a viscous and/or pasty product on a substrate (1) through the apertures (3) of a stencil are provided. A hollow receptacle (7) for the product is provided with a lower aperture (19) which is orientated towards the stencil. The lower aperture (19) of the receptacle is delimited such that its length is adjusted to the dimensions of the substrate and that its width is a function of the speed of execution of the screen printing. This delimitation is implemented by sealing members (15, 16) preferably comprising two wipers (15) on respective sides of the aperture, transverse with respect to the direction of displacement of the receptacle, orientated one towards the other and inclined with respect to the horizontal between the wipers at an angle of between 120° and 180°, said wipers being transversal and intersecting with the section of the receptacle. A pressure is exerted upon the viscous product in the receptacle, which pushes it towards the stencil between the wipers to distribute it, and upon the wipers, applying pressure to these in order to push the wipers onto the stencil. The receptacle is displaced across the stencil at the same time as the pressure is being exerted on the product. The invention can be applied in the electronics industry for carrying out depositions of adhesive or soldering paste.

Title: Configurable monitoring of program viewership and usage of interactive applications
Inventor: DEL SESTO ERIC E
IPC: H04N7/173
Filed: 1999-04-29
Abstract: A system and method provide sophisticated analysis of program viewership by executing interactive applications that generate responses describing the viewers' behavior. A broadcast server maintains a database of interactive applications each preferably associated with a program that will be broadcast. The interactive applications preferably include monitoring interactive applications that are configured to selectively monitor viewership, interactive application usage, and reception terminal usage. When the program is broadcast, the monitoring interactive application is inserted into the broadcast feed and delivered to a broadcast receiver such as a television set-top box. The broadcast receiver includes a processor, memory, and other hardware necessary to execute the interactive application. When executed, the interactive application monitors usage of the broadcast receiver, including, for example, the program watched by the subscriber, the entry and exit paths to the program, whether the volume was changed during the program, and the usage of interactive applications. The monitored data is sent in a response packet to a local data center at, for example, the cable headend. The local data center supplements the response with subscriber information from one or more subscriber databases, including marketing information such as the subscriber's age, race, and income. Information about all of the subscribers is aggregated by the local data center and transmitted to a master data center. The master data center aggregates all of the received information, supplements it if possible with additional subscriber information, and provides reports to the broadcaster indicating the geographic, demographic, and psychographic profiles of the program viewers.
