Patent CA-2270043-C (CA)
Title: Network resource server
Inventor: LIEN ROBERT LEROY
IPC: H04Q3/00
Filed: 1999-04-27
Granted: 2003-12-09
Abstract: A network resource server is deployed in a convergent telecommunications network for providing traditionally service circuit type applications to both circuit switches and packet switches of the convergent network. The network resource server includes a variety of processors for accommodating specific application requests from nodes within the convergent network. Advantageously, the network resource server has a greater capacity than traditional service circuit nodes and is able to serve both the circuit-based network elements and packet-based network elements in a convergent network. For this reason, the network resource server eliminates the need for traditional service circuit nodes and various types of data servers.

Title: Multiplexing system and method for integrated voice and data transmission on network
Inventor: BURG FREDERICK MURRAY
IPC: H04L12/64
Filed: 1998-10-23
Granted: 2003-08-12
Abstract: An integrated sub-rate multiplexing system and method optimizes use of transmission bandwidth in integrated networks. For example, transmission capacity of the Public Switched Telephone Network (PSTN) is assigned to various traffic types according to the instantaneous needs, illustratively in an enhanced (T1, T2) -environment. When speech and data packets compete for bandwidth under certain conditions portions of data are concatenated to the voice segment, increasing bandwidth efficiency.
Patent CA-2278523-C (CA)
Inventor: MAYFIELD STEPHEN
IPC: G01N33/68
Filed: 1998-01-16
Granted: 2013-06-18
Abstract: The present invention relates to a gene expression system in eukaryotic and prokaryotic cells, preferably plant cells and intact plants. In particular, the invention relates to an expression system having a RB47 binding site upstream of a translation initiation site for regulation of translation mediated by binding of RB47 protein, a member of the poly(A) binding protein family. Regulation is further effected by RB60, a protein disulfide isomerase. The expression system is capable of functioning in the nucleus/cytoplasm of cells and in the chloroplast of plants. Translational regulation of a desired molecule is enhanced approximately 100 fold over that obtained without RB47 binding site activation.

Filed: 2000-03-27
Granted: 2008-12-30
Abstract: This invention provides a device for removably securing a wide variety of objects to different surfaces utilizing a partial vacuum. The device includes flexible material comprising one or more opening(s), wherein each opening is capable of forming a continuous seal with a portion of an object and the remaining material is capable of forming a continuous seal with a surface. The size of the opening and the size of the material can vary within the constraints that adequate material remains surrounding the opening to enable a continuous seal to be formed with a surface when an object is inserted into the opening. The device is used by inserting an object into an opening, thereby forming a continuous seal between the object and the opening and pressing the device against a surface, displacing air to create a partial vacuum in a manner that causes a continuous seal to form between the flexible material and the attachment surface, thereby removably securing the object to the surface.

Abstract: An engine automatic start stop control apparatus controls an engine (10) of a vehicle to be automatically stopped or started in response to driving conditions of a vehicle. Particularly, the apparatus is applied to the vehicle that performs idle stop control for reduction of discharge gas. Herein, the apparatus controls the engine to restart based upon determination for restarting the engine under an engine stop mode. Namely, the apparatus controls the engine to restart if a driver depresses a clutch pedal or if a driver does not depress a brake pedal during an engine stall in which engine speed becomes zero. Thus, it is possible to restart th e engine by prescribed operations even if the driver mistakenly recognizes that the engine is. stopped by automatic stop control although the engine actually stalls due to an error operation of the driver so that the engine speed becomes zero. This improves drivability for the driver who handles the vehicle, particularly a hybrid vehicle which is capable of independently running by using an electric motor only.

Abstract: A biopsy instrument comprises a canula slidingly disposed in a finger tube having a finger at its distal end. By forward displacement of the finger tube relative to the canula the finger is inserted into an opening in the canula wall near its cutting front edge. Thereby a piece of tissue located inside the canula is severed from living tisue. The instrument has a steel spring compressed against a force of at least 35 N for displacing the canula and the finger tube in the tissue cutting step.  The stopper on which the moving canula impacts includes an element of an impact damping design. The impact damping element is made of high impact grade ABS-polymer or a polymer with similar physical properties. It can be used also with known biopsy instruments having a moving canula and/or stylet driven by powerful spring means. Also is described a loading assembly for a biopsy apparatus incorporating the biopsy instrument.

Abstract: A vehicle electric drive system includes an internal combustion engine, an electric motor/generator driven by the engine, a first inverter/rectifier coupled to motor/generator, a buss coupled to the first inverter/rectifier, a second inverter/rectifier coupled to the buss, and a traction motor/generator coupled to an output of the second inverter/rectifier, an operator speed control member, and a controller coupled to the second inverter/rectifier for controlling a current output of the second inverter/rectifier as a function of a positio n of the speed control member. Also included is an operator controlled foot pedal and a transducer coupled to the foot pedal and generating a signal representing foot pedal position which is supplied to the controller. The controller limits current supplied by the second inverter/rectifier to the traction motor/generator to a limit current as a function of the transducer signal. The controller, foot pedal and transducer cooperate to vary the limit current in response to movement of the foot pedal. A spring biases the foot pedal to an upper limit position. The controller causes the second inverter/rectifier to supply to the traction motor/generator a maximum amount of current, (such maximum current being a function of the foo t pedal position), but not more thanthat required to achieve the speed commanded by the speed control.

Title: Method and apparatus for performing packet loss or frame erasure concealment
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Granted: 2007-08-07
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

Title: Torque converter
Inventor: INOUE KOJI
IPC: F16H41/24
Filed: 2001-02-23
Granted: 2005-01-04
Abstract: A torque converter includes a turbine impeller integrally connected to a pump impeller, a side-cover having a boss and covering the turbine impeller, and a turbine shaft extending through the boss and connected to the turbine impeller. A radial bearing and a one-way clutch are disposed axially adjacent to each other between the boss of the side-cover and the turbine shaft. The radial bearing serves to retain the boss and the turbine shaft concentrically, and the one-way clutch connects the turbine shaft and the side-cover to each other, when a back load is applied to the turbine shaft. Therefore, a load received by a clutch element of the one-way clutch such as a sprag between the turbine shaft and the side-cover is equalized. Thus, when a back load is applied to the turbine shaft, a slipping between the turbine impeller and the pump impeller is prevented, thereby providing a good engine brake effect.
