Patent CA-2285650-A1 (CA)
Inventor: PROUST STEPHANE
IPC: G10L19/005
Filed: 1999-02-03
Abstract: Un signal audio codé par trames successives est représenté par un flux binaire (F) reçu avec une information (BFI) indiquant d'éventuelles trames effacées. Pour chaque trame, on filtre un signal d'excitation (E k(n)), formé à partir de paramètres d'excitation (EX(n)) qui sont récupérés dans le flux binaire (trame valide) ou estimés d'une autre manière (trame effacée), au moyen d'un filtre de synthèse (22) pour obtenir un signal décodé (.SIGMA. n(t)). On effectue une prédiction linéaire du signal décodé jusqu'à la trame précédente pour estimer un filtre de synthèse relativement à la trame courante. Les filtres de synthése utilisés tant qu'aucune trame n'est effacée sont conformes aux filtres de synthèse estimés. Si une trame n 0 est effacée, on détermine le filtre de synthèse utilisé pour une trame subséquente n 0+i par une combinaison pondérée du filtre de synthèse estimé relativement à la trame n 0+i et d'au moins un filtre de synthése qui a été utilisé depuis la trame n 0.

Title: Cyclin dependent kinase (cdk)4 inhibitors and their use for treating cancer
Inventor: DENT BARRY ROY
IPC: A61K31/433
Filed: 1998-04-28
Abstract: Certain derivatives of acridones and benzothiadiazines have been found to have anti-cancer properties by virtue of their specific inhibition of the cyclin D dependant kinase CDK4. These molecules inhibit CDK4 activity more than they inhibit the activity of other such kinases (e.g. CDC2 and CDK2). This specificity results in an improved therapeutic index when used as drugs to treat susceptible cancers.

Filed: 1999-11-05
Abstract: A dual steering system for controlling the steering of a motor grader is disclosed. The dual steering system comprises a joystick moveable along a plurality of axes. Movement of the joystick a first direction along a first axis transmits a first electrical input signal to an electronic control computer which in turn transmits a first control signal to electro-hydraulic actuators associated with the right steering cylinder and left steering cylinder of the motor grader. The right steering cylinder and left steering cylinder cause rotation of the front tires in a first direction in response to the first control signal. Movement of the joystick a second direction along the first axis transmits a second electrical input signal to an electronic control computer which in turn transmits a second control signal to electro-hydraulic actuators associated with the right steering cylinder and left steering cylinder of the motor grader. The right steering cylinder and left steering cylinder cause rotation of the front tires in a second direction in response to the second control signal.      The motor grader can also be steered by rotation of a steering wheel also acting through the right steering cylinder and the left steering cylinder.

Title: Method and apparatus for handling and disposal of oil and gas well drill cuttings
Inventor: DIETZEN GARY H
IPC: E21B43/34
Filed: 2000-02-29
Abstract: A method and apparatus for removing drill cuttings from an oil and gas well drilling platform provides for the separation of drill cuttings from at least a volume of the well drilling fluid (i.e. drilling mud) on the drilling platform so that the drilling fluids can be recycled into the well bore. The cuttings are then transferred to a cuttings collection area on the platform. The separated drill cuttings are then suctioned with a first suction line having an intake portion. The suctioned drill cuttings are transmitted to a vacuum holding tank or multiple tanks on the platform, each having a tank interior. A vacuum is formed within the holding tank interior with a blower that is in fluid communication with the tank interior via a second vacuum line. The holding tank is then connected to a floating work boat with a discharge flow line. Cuttings are then transmitted from the tank on the platform to the work boat via the flow line. In an alternate embodiment, cuttings can be transferred to an underwater storage area. In this fashion, multiple holding tanks on the drilling platform can be used to store cuttings until a work boat arrives.    The work boat can be provided with its own high capacity work boat holding tank (for example 100-1000 barrels) for receiving cuttings from the multiple tanks on the drilling platform when disposal is desired. The underwater storage tank can be used in place of or as a supplement to the work boat holding tanks.

Abstract: The present process permits a method of determining the species of a raw log based on its bark type. The image of the bark is manipulated to fit into a known bark pattern for a certain species. The image of the raw log bark is taken by some type of camera/video/scanner. The image of the raw log bark is manipulated to fit into many known bark patterns allready stored in a Computer. The pattern that most closely resembles the raw log bark by taking the least amount of manipulation is the decided species of the raw log. The pattern resemblance is based on a varying degree of certain identifying features for all bark (for example cracks, pits, flakes, crevices, etc).

Title: Optical add/drop arrangement for ring networks employing wavelength division multiplexing
Inventor: VESELKA JOHN J
IPC: H04B10/275
Filed: 2000-06-20
Abstract: An add/drop arrangement using broadband optical couplers provides a low-loss, highly flexible add/drop capability for survivable wavelength division multiplexed (WDM) ring networks. At each node in the ring having the broadband optical coupler-based add/drop element, a portion of optical signal power of the entire WDM signal (i.e., all optical channels) is tapped off so that one or more optical channels of particular wavelengths can be dropped at the node.  Information (e.g., data) to be added at the node is supplied in an optical channel that is added to the WDM signal via the broadband coupler. Because the add/drop element uses a broadband coupler, another portion of optical signal power of the WDM signal, including any added optical channels, passes through the node onto the ring. Depending on the specific ring topology being used with the broadband coupler-based add/drop arrangement, additional wavelength assignment and handling measures may be required. For example, certain ring topologies may experience interference between optical channels of particular wavelengths due to possible re-circulation of these optical channels beyond the add and drop nodes (e.g., after an optical channel passes its destination node). According to one illustrative embodiment, a node is equipped to perform wavelength conversion and/or wavelength suppression to prevent undesirable re-circulation of optical channels.
Patent CA-2313312-A1 (CA)
Title: System, method, and computer program product for smart card to smart card transactions
Inventor: CRABTREE WALDEN
IPC: G06Q20/00
Filed: 2000-06-30
Abstract: A smart card terminal (910, 920, 930, 940) receives a first smart card and deducts value from the smart card. The value to be deducted is determined by a smart card holder and is relayed to a smart card terminal (910, 920, 930, 940) via a user interface on the smart card terminal. If a single slot smart card terminal is utilized for a transfer between smart cards, then the terminal deducts the value from the first smart card that is then removed from the slot. The transaction is completed when a second smart card is inserted into the slot and the value deducted from the first card is written onto the second card. If a multiple slot smart card terminal is utilized then the first smart card is inserted into a first slot and the second smart card is inserted into a second slot. A user interface guides the smart card holder(s) through the process of deducting value from the first smart card and writing it onto the second smart card. Long distance or remote transfers of value between smart cards can also be performed. A remote transfer implies two smart card terminals communicating with one another. Such communication can be telephone based or computer based and can utilize telephone networks 950 or computer data networks 960. Smart card transfers can also be effected in a non-real-time basis meaning a first smart card can have value deducted and stored in a data network smart card server 970 for later retrieval by a second smart card.
