Inventor: LINDMARK MAGNUS CARL WILHELM
IPC: H02P27/06
Filed: 1995-02-24
Abstract: A device for controlling a three-phase induction motor that is driven by an inverter connection. The inverter is furnished to be fed with full-wave rectified grid alternating voltage (U) and supply the motor's various phases (R, S, T) with the drive voltages phase-displaced in the normal way and which consist of mainly square, in relation to a virtual zero reference level, positive and negative half-periods which alternate at a fixed or adjustable drive frequency corresponding to the required speed. The full-wave rectified grid alternating voltage (U) supplied to the inverter is arranged to be supplied to respective motor phase (R, S, T) via an electronic switch connection (TR1H, TR1L; TR2H, TR2L; TR3H, TR3L) whose respective on and off periods are determined by the drive frequency which is generated by an oscillator device (15; 25). The last mentioned is arranged to be supplied with a voltage (Um) which directly or indirectly represents the rectified grid alternating voltage (U) for the purpose of modulating the drive frequency with a signal that represents the variations in amplitude of the rectified grid alternating voltage. The invention also comprises a method of controlling an induction motor of the type specified.

IPC: H04L47/22
Filed: 1995-11-10
Abstract: In a congestion control method for a system having a first network of one congestion control unit representing a subset of a switching network constituted by a set of switching nodes connected to each other and a second network which serves as a subset of the switching network and does not have a switching node common to the first network, thereby controlling congestion of the first and second networks, the traffic is classified into first traffic generated in the first network and reaching a target switching node of the first network through a switching node in the first network, second traffic having the switching node of the first network as a start point and directed toward the second network, third traffic having a switching node in the second network as a start point and transmitted through a switching node in the second network and a switching node in the first network, and fourth traffic which does not correspond to any one of the first traffic, the second traffic, and the third traffic.          Upon occurrence of congestion in the first network, the traffic flow amounts and traffic rates of the first traffic and the second traffic are limited in the first network.
Patent CA-2163006-A1 (CA)
Title: Fuzzy logic controller
Inventor: SULTAN LABIB
IPC: G06F9/44
Filed: 1993-05-20
Abstract: This invention relates to the design and implementation of real-time knowledge-based fuzzy controller system for general purpose industrial applications. The controller is implemented in three technological bases (software, VLSI and neural network). In another aspect the invention relates to the design of an Intelligent system which implements decisionmaking procedure based on approximation, association and reasoning with fuzzy patterns and their clearness assessments rather than the use of Max-Min computation over fuzzy relational matrices usually applied in approximate reasoning procedures in similar systems. According to this design the fuzzy controller is a device which operates at the level of fuzzy pattern processing where each control task is expressed through the attributes of fuzzy patterns (syntax and content, domain and clearness measure), and the elementary cognitive activities which the human performs with these patterns such as: recognition, generation, assessment, association, pattern matching, approximation, etc. The fuzzy controller utilizes a new scheme for approximate reasoning with fuzzy patterns called the Clearness Transformation Rule of Inference (CTRI). This mechanism offers a spectrum of advantages broadening the functional Intelligence of the controller to handle complex human tasks, improving the performance and accuracy of the controller and reducing the computational requirements. The fuzzy controller presented in the invention can be applied in general engineering practice, financial, medical, process control, pattern recognition and other areas requiring knowledge-based bahaviour in decision making.

Patent CA-2172535-A1 (CA)
Title: Virtual reality network
Inventor: DURWARD JAMES
IPC: G06T19/00
Filed: 1994-09-22
Abstract: A virtual reality system has a database for defining one or more three-dimensional virtual spaces. A communication unit establishes a communication between the database and a user, and a data communication unit communicates data from the database to the user so that the user's computer may display a portion of a selected virtual space on the user's head mounted display. The communications unit also receives data corresponding to the position, orientation, and/or movement of the user relative to a reference point and uses the data to define a virtual being within the virtual space, wherein the position, orientation, and/or movements of the virtual being are correlated to the received data. Preferably, the data communicated to the user typically corresponds to the portion of the virtual space viewed from the perspective of the virtual being. The system defines other virtual beings within the database in response to position, orientation, and/or movement data received from other users, and the portions of the virtual space communicated to the other users may correspond to the perspectives of their associated virtual beings. The system periodically updates the database and communicates the updated portions of the database to the users to reflect changes in perspective of the virtual beings and changes in the position of moving objects within the virtual space. The system also supports audio communication with the users. To reduce the amount of data communicated between the computer and each user, visual and sound priority spaces may be defined within the portion of the virtual space data communicated to the user, and elements within selected priority spaces may be updated in priority over other priority spaces.

Filed: 1993-10-27
Abstract: A granular pharmaceutical preparation prepared by granulating finely powdered Ebselen(2-phenyl-1,2-benzisoselenazol-3(2H)-one) using a hydrophilic polymer, and an aqueous suspension thereof. The Ebselen granular pharmaceutical preparation of the present invention is excellent in its performance as an oral preparation for use in stomach tube administration. That is, since it can be dispersed easily and uniformly when suspended in water or an aqueous solution before its use, and the suspension can be maintained in excellent dispersed state, preparation and tube administration of the drug solution can be made easily. Also, its dose is accurate because the administration can be effected with no drug or drug solution remained in the tube after the administration. In addition, the granular pharmaceutical preparation of the present invention is also suited for its large scale production, because it can be produced without employing special apparatuses and production steps.
Patent CA-2176168-A1 (CA)
Inventor: BAFFONI FRANK A
IPC: A61B7/02
Filed: 1996-05-09
Abstract: A multiple phase stethoscope has a chest piece with a plurality of diaphragms and an equal plurality of sound compartments.  Sound is carried from each of these compartments through a separate lumen, the plurality of lumens making up a tube assembly.  The lumens are at least partially separated from each other by a flexible membrane which serves as a transducer to convert acoustic energy into mechanical motion, thus allowing the sound in the lumens to be combined.  One of the lumens is open to the atmosphere through ear pieces, while the other lumen is sealed with a material and/or pressure different from the ambient environment.  The geometry of the diaphragms, the second compartments, and the lumens; the materials used for the flexible membrane in the lumens; and the pressure of the material in the lumens are all selected to enhance and/or attenuate at least a part of a frequency spectrum of the sounds.  If two outer lumens are provided and are different around branches leading to the separate ear pieces, a stereophonic effect is created.  This effect can be obtained by altering materials or geometry, e.g., by spiraling the outer lumen around the branches at different angles.
