Patent CA-2334999-A1 (CA)
Title: Procede et appareil de correction d'erreurs de decalage affectant le courant continu dans des denumeriseurs
Inventor: WALKER BRETT CHRISTOPHER
IPC: H03C3/40
Filed: 1999-06-29
Abstract: La présente invention concerne un procédé et un appareil permettant de corriger adaptativement des erreurs de décalage qui affectent le courant continu et qui sont imposées à des signaux dans un dispositif de communication. L'invention porte sur un circuit et un procédé de correction à boucle de rétroaction (122) qui permettent de mesurer et réduire des erreurs de décalage en question qui sont imposées à des signaux de transmission analogique par des dénumériseurs de transmission (102) et des filtres analogiques de reconstruction. On fait intervenir une boucle de rétroaction numérique pour débarrasser les signaux desdites erreurs de décalage, avant transmission. Selon un mode de réalisation, la boucle de rétroaction numérique comprend une paire de numériseurs, un circuit de correction numérique (222) du décalage considéré et une paire d'additionneurs (228, 230). Les signaux de transmission sont numérisés, filtrés et traités numériquement par le circuit de correction (222) en vue de la production de signaux de correction de décalage égaux aux erreurs de décalage qui affectent le courant continu et qui sont présentes dans les signaux de transmission. Les signaux de correction viennent s'ajouter aux signaux dans la bande de base, ce qui permet de débarrasser les signaux de transmission des erreurs indésirables de décalage en question.

Title: Coupling for excavator teeth and the like
Inventor: FERNANDEZ MUNOZ ROBERTO
IPC: E02F9/28
Filed: 1999-07-01
Abstract: The coupling between the excavator tooth and the tooth-holder is achieved by combining three successive areas from the medial part of the coupling piece to its free end, comprising a fist area of straight stepped guides which open at the side external surfaces of the coupling piece followed by an area of guiding by means of revolution surfaces opposite to each other, and a third terminal area formed like a prismatic rod of which the axis coincides with the piece axis.
Patent CA-2337656-A1 (CA)
Inventor: CRANE KENNETH
IPC: G06Q50/30
Filed: 2001-02-20
Abstract: An automated system provides a user with the ability to automatically configure intermodal freight transportation in a convenient and efficient manner. In a first preferred embodiment, information relating to freight transportation resources may be accessed via the Internet and a web interface. Although it is preferred that the Internet be used for access, it is contemplated that any known type of access to a program or database would be suitable. Regardless of how a user gains access to the system, the system will provide the user with the ability to identify origination and destination information for a freight shipment that is to travel via intermodal freight carriers. Additionally, the user may enter data relating pick-up and/or delivery scheduling for the shipment. Once this information has been identified, the system automatically identifies all available trucking and rail resources which are compatible in terms of scheduling for delivery of the desired load. This information is assembled into one or more combined intermodal freight transportation alternatives that provide transportation for the freight shipment between the origination and destination locations. The information on available resources is then presented to the user for selection from among the various shipping alternatives.
Patent CA-2338085-A1 (CA)
Title: Intelligent traffic routing
Inventor: MALIK DALE W
IPC: H04Q3/00
Filed: 1999-03-16
Abstract: When a subscriber calls into its Internet Service Provider (ISP), a central office receiving the call is triggered to perform a Local Number Portability (LNP) query. This LNP query is sent to an Intelligent Traffic Routing and Control (INTRAC) unit resident on a Service Control Point (SCP) which determines whether the call is to an ISP. If the call is to an ISP, the INTRAC unit polls a Remote Authentication Dial-In User Service (RADIUS) server to determine whether resources are available.      The RADIUS server tracks the resources of the ISP and of other ISPs and informs the SCP of the available resources.      The SCP then inserts the Local Routing Number (LRN) of the preferred resource into a reply that is sent to the central office. If resources are not available, the call is terminated before signaling occurs with any switch associated with the ISP. On the other hand, when resources are available, the subscriber can be directed to the preferred resource for the subscriber. The subscriber, for instance, can be directed to an access server within the ISP that has excess capacity or can be directed to an access server that provides the best service for the subscriber, whereby subscribers can be directed to X2 type service if they have an X2 modem or to K56Flex type service if they have a K56Flex modem. As another example, if one ISP is at maximum capacity, the subscriber can be directed to a second back-up ISP.

Inventor: DEEDS W EDWARD
IPC: H01J37/32
Filed: 1999-10-01
Abstract: A waveguide structure (1) has at least one shaped slot (3) machined in the wall of the waveguide (2). The slot (3) is configured such that a high voltage is generated across the slot (3) when the waveguide (2) is excited with high-power microwaves. The strong electric fields generated in the region of the slot can be used to produce a non-equilibrium plasma discharge (7) in a working gas (9) in the vicinity of the slot (3). Various substrates can be translated past the slot (3) and exposed to the plasma species generated by the microwave discharge. The slotted waveguide structure (1) is designed to operate as a traveling wave structure with microwave energy uniformly dissipated along the length of the slot (3). The structure can be designed to operate over the pressure range of about 10 Torr to atmospheric pressure, i.e., about 760 Torr, using a wide variety of gases and gas mixtures.

Patent CA-2353437-A1 (CA)
Inventor: LOWE HARRY E
IPC: E01F9/06
Filed: 2001-07-24
Abstract: A very low-profile snowplowable pavement marker mounted in an elongated groove formed in a highway pavement, the groove extending longitudinally of the highway and exposing the reflective highway marker to the headlights of oncoming motor vehicles when their approach distance from the reflective highway marker is adequate for highway guidance purposes. The reflective highway marker is a metal casting with a reflector mounted in a pocket formed in the casting. The casting is adhesively installed in a deepened section of the groove. The protective rails of the casting are situated slightly above the pavement surface, but are significantly lower than rails of prior art snowplowable castings. The leading edge of the reflector support is below pavement level and allows light from oncoming headlights to enter the reflector without the shadowing effect prevalent in conventional low-profile marker castings. The elongated groove is much shallower and longer than grooves of prior art, and allows for car tires to enter and clean the reflector in the casting.

Title: Digital key telephone set and digital key telephone system
Inventor: TAKAHASHI TOSHIAKI
IPC: H04M1/00
Filed: 2001-08-29
Abstract: A clock generating circuit generates a clock of a rate corresponding to a Dch rate in response to a specification from the exterior. A counting circuit detects completion of reception of one frame by counting the clock number up to "11" at timing at which a start bit detecting circuit detects a start bit in a serial signal. An S/P converting circuit fetches a serial Dch signal bit by bit in synchronism with the clock, outputs the latest fetched 10 bits in a parallel form and latches eight bits of a real data portion among the output data into a latch circuit at the time when reception of one frame is completed. In parallel with the above operation, a parity calculating circuit and flag/interruption generating circuit set various flags and generate a reception completion interruption.
