Patent CA-2319450-C (CA)
Title: A method to automatically and accurately portion a sequential flow of objects by weight
Inventor: GUDMUNDSSON BJARNI
IPC: G01G19/387
Filed: 1998-11-18
Granted: 2004-07-13
Abstract: The invention solves the problem of sufficiently accurately portioning by weight a sequential stream of objects with known individual weights, without having to return a considerable part of rejected excess objects to be processed again. This is achieved by accumulating excessive objects into one or more holding areas where they will be used as the basis for subsequent portions, instead of being rejected and reprocessed. This method makes it possible to use relatively simple and inexpensive equipment for sufficiently accurate portioning by weight in the fish and food processing industries, which requires highly complex and expensive equipment using existing technologies.

Patent CA-2328437-C (CA)
Inventor: BAKER MATTHEW P J
IPC: H04L12/70
Filed: 2000-01-24
Granted: 2007-09-25
Abstract: In order to enable isochronous data to be transmitted over communications systems which may introduce timing jitter each packet of isochronous data is provided with a timestamp which indicates to a receiver the time at which a packet should be processed. The receiver notes the time the first packet of a data stream arrives and adds a given offset time which is greater than or equal to the maximum jitter to produce a time t1. Each succeeding packet is processed at a time t- t1 +(Tn-T1), where T1 is the timestamp in the first data packet and Tn is the timestamp in the current packet. Thus the processing at the receiver is dependent on the relative times of arrival of the packets rather than the absolute times defined by the timestamps.

IPC: H04J13/00
Filed: 1999-07-14
Granted: 2007-04-10
Abstract: A method for controlling transmission power in a radio system and in a WCDMA system network in particular for maximizing cell capacity. An acceptable transmission power margin and an optimum power level, which may change specifically for each connection and service class, are determined for the transmission power. Transmission power is adjusted using power control steps utilizing am incoming power control command and previous power control steps.      The power control step size is adjusted as a sum of a fixed and a variable dynamic step size where the dynamic value is obtained on the basis of the measured value and the target value of the signal-to-noise ratio. Information on the network state can be obtained by comparing AC and LC data and the cell capacity can be maximized by controlling the amount of transmission power calculated by the mobile station before the final power transmission.

Title: Method and system for transmission of decrypting information
Inventor: KUDELSKI ANDRE
IPC: H04N21/4623
Filed: 2001-01-24
Granted: 2010-07-06
Abstract: At the moment of the diffusion of Pay-TV with multi-channel signals, each channel is associated to authorization messages (ECM) which allow to decrypt this channel according to the rights of the subscriber. When changing channel, a very short time is accepted before one has determined these new rights in relation with the new channel. The heavy encrypting algorithms are thus excluded. To avoid this drawback, to decrypt a channel, a system is proposed using the combination of the authorization information for a channel (ECM), and thus encrypted by a fast algorithm, with authorization information (MECM) for a group of channels. These latter are encrypted by a high security algorithm and are thus slower to decrypt.
