Patent CA-2271779-A1 (CA)
Inventor: GINZBOORG PHILLIP
IPC: G06Q20/00
Filed: 1997-11-11
Abstract: The invention concerns a method for the implementation of charging in a telecommunications system including customer terminals used by customers for ordering services and servers for providing services to customers. In order to implement the charging of services easily especially in a multimedia environment, at least one separate billing server is used in the network so that each customer terminal has a dedicated billing server. A contract message is sent to the customer terminal stating that the customer must make a contact on the selected service, and the customer's acceptance of the contact is sent from the customer terminal to the billing server in the network.      The billing servers of the network are used for transferring charging records to the billing system so that the transfer of the charging record(s) concerning the selected service involves at least one billing server.

Title: Error diffusion for color images with semi-vector quantization
Inventor: FAN ZHIGANG
IPC: H04N1/52
Filed: 1999-05-20
Abstract: A method for color error diffusion using semi-vector quantization is proposed that simplifies error diffusion calculations. When three color separations are used, the two separations with the most visually perceptive color output are compared with one another to determine their output colors, while the third, least visually perceptive separation, is treated separately.  A correction term may be applied to the third separation based on the color output of the first two separations to insure uniformity of ink coverage. This method yields results close to vector quantization and also minimizes fluctuation in the two most visually perceptive output colors. Of course, this method may be used with more than three color separations. For example, when four color separations are used, the least visually perceptive color is processed differently than the three other color separations.

Patent CA-2282337-A1 (CA)
Inventor: GODAU ECKHARDT
IPC: D06B3/10
Filed: 1997-10-02
Abstract: The invention relates to a method for the continuous dyeing of warp ends, in particular cotton warp ends, with indigo or other dyestuff groups which, after impregnating and squeezing out, require oxidation or thermal treatment for fixing. The method eliminates the disadvantages of traditional methods for the continuous dyeing of warp ends. In particular, the required bath amount is considerably reduced by this method. By using a new dyeing reactor (1), the residence time of the warp ends in the dyeing installation can be varied without having to increase the bath volume. The option of heating or cooling the dyeing bath enables a fixing temperature between below room temperature and over 100 ~C to be chosen. Optimal conditions can thus be created for all dyeing methods which are habitual for warp ends. In this way, the number of immersion-oxidation processes in the indigo dyehouse can be reduced and the growing demand for indigo blue jeans material with different wash resistances and shades can thus be catered for with increased flexibility. And the same can be done for black and coloured denim.

Patent CA-2290986-A1 (CA)
Inventor: FIEDLER JURGEN HANS
IPC: A61K6/00
Filed: 1998-05-29
Abstract: Improved two component polymerizable polyorganosiloxane compositions are described, particularly for use in making dental impressions, having improved tear strength and wettability. Improved tear strength results from inclusion of a quadri-functional polysiloxane having a vinyl content of 0.16 to 0.24 m-mole/g. Working time is maintained by including sufficient amounts of a retarder composition that delays onset of the vinyl polymerization.  Wettability is improved by including a surfactant resulting in a surface contact angle with water at three minutes of less than 50~. The surfactant chosen has an HLB of 8-11, such that the wetting contact angle is achieved within less than two minutes and remains wetting throughout the working time of the impression taking, substantially improving impression quality. A low viscosity impression material is improved and includes a base component and a catalyst component. Both components are siloxane-based materials.
Patent CA-2292729-A1 (CA)
Title: Adjustable support mechanism
Inventor: RUSSELL EDWIN ROBIN
IPC: F16H25/00
Filed: 1999-12-20
Abstract: A mechanism is disclosed for effecting the relative angular adjustment of a pair of coupled members. A rotor is mounted on an axle that is mounted on one member, the rotor having a planar face on one side that has an arcuate groove formed therein such that the radial distance between the groove and the axle varies in a gradual manner with variation in angle about the axle. A pin or the like protuberance is mounted on the other member of the pair so as to enter and be slidingly engaged by the groove. The arrangement is such that rotation of the rotor causes relative angular movement of the members, but pressure between the members will not cause the rotor to turn. The application of this mechanism to the adjustment of keyboard platforms and monitor supports is disclosed.

Patent CA-2297857-A1 (CA)
Title: Headlight warning system
Inventor: ARCHE GLENN S
IPC: G01R31/44
Filed: 2000-01-31
Abstract: A headlight warning system incorporates an engine running sensor and a headlight sensor coupled to a control circuit for activating a warning device, such as a buzzer, when the headlights have been left on for a first period of time after the engine has stopped running, and for deactivating the warning device either after a second period of time, if the engine is started, or if the headlights are shut off. The engine running sensor inductively senses a vehicle ignition signal. The headlight sensor magnetically senses the current in one of the battery cables using a Hall effect sensor in series with a magnetic flux collector encircling the battery cable. If the battery current exceeds an adjustable threshold, the headlights are assumed to be on. Following the deactivation of the warning device after the second period of time, the headlight warning system is reset by either starting the engine or by shutting off the headlights. The headlight warning system is self-contained, requires no modification of the existing vehicle electrical system, and is easy to install for retrofit applications.

La fibre est transformée en un tapis sur le tambour et le tambour est mis en rotation de manière que les secteurs (26) passent par un premier lavage puis un second lavage avec un fluide de lavage progressivement plus propre. Chaque secteur comprend deux systèmes de drainage distincts. Un système de drainage évacue la première eau de lavage (52) après qu'elle soit passée à travers le tapis, puis il est bloqué tandis que le secteur passe par le second lavage (58). Le second fluide de lavage plus propre est ainsi gardé séparé du premier fluide de lavage plus contaminé, puis il est recyclé afin d'être utilisé dans des cycles ultérieurs comme premier fluide de lavage.

Title: Mitigation of false co-channel uplink reception in a processing satellite communication system using stagger
Inventor: WRIGHT DAVID A
IPC: H04L69/40
Filed: 2000-03-14
Abstract: The present invention provides a method and apparatus for preventing show-thru (and therefore misinsertion of unintended traffic) among uplink beams transmitted to a satellite. The method includes the steps of selecting (402) an uplink A stagger value, selecting an uplink B stagger value, coding (404) uplink A data to generate coded uplink A data, and coding (406) uplink B data to generate coded uplink B data. Subsequently, the method transmits (412) the coded uplink A data, staggered by the uplink A stagger value, in the uplink A and further transmits (414) the coded uplink B data, staggered by the uplink B stagger value, in the uplink B. During coding (404, 406), the method may use a full length error correcting code capable of correcting t errors. In such a case, the method generally selects an uplink B stagger value differing from the uplink A stagger value by more than t codeword symbols. Alternatively, the method, during coding (404, 406), may use a shortened error correcting code capable of correcting t errors. In such a case, the method generally selects an uplink B stagger value differing from the uplink A stagger value by at least one codeword symbol. The method is not limited to any particular number of uplink beams and may provide staggering for all same color uplink beams in a predetermined reuse pattern, for example.
