Patent CA-2275599-A1 (CA)
Title: Multi-speed winch
Inventor: AHO RICHARD E
IPC: C03B19/10
Filed: 1997-12-16
Abstract: A multi-speed winch (70, 80) is attached to a motor vehicle (200) and is hydraulically powered by the vehicle's power steering system (12) or other hydraulic source innate to the host vehicle (200). The winch operates in either a low-speed, high-torque mode for moving heavy loads, a high-speed, low-torque mode for quickly releasing or retrieving cable (82), a free-spooling mode for manually releasing cable (82), and a brake mode for holding the cable and load at a fixed position. The high-speed mode is enabled by coupling the drive shaft (75) directly to the winch drum (80). The low-speed mode is enabled by coupling the drive shaft (75) to the winch drum (80) through a planetary gear assembly (83a-c, 84). In an alternate embodiment, high-speed mode is enabled by coupling the drive shaft (248) to the winch drum (250) through one of two planetary gear assemblies. Free-spooling mode is achieved by disengaging the drive shaft (248) from the winch drum (250), and brake mode is achieved by engaging both the direct drive coupling (120) and the sun and planet gear arrangement (83a-c, 84). The four operational modes are selected by four different combinations of positions of a direct drive selector handle (134) (which determines the position of the coupling plate) and a gear reduction handle (8) (which determines the position of the locking pin). In an alternative embodiment, the four operational modes are selected by four different combinations of positions of a direct drive solenoid (140) and a gear reduction solenoid (148). A four-way, dual solenoid-operated valve (20) controls the flow of pressurized hydraulic fluid to the winch motor (70).

Title: Administration and utilization of private keys in a networked environment
Inventor: EPSTEIN MICHAEL
IPC: H04L9/32
Filed: 1998-12-14
Abstract: In a public key cryptosystem, the private keys of users, as encrypted with a symmetric algorithm by using individual user identifying keys, are stored at the server end along with the users' respective public keys. The server uses an ID of a user transmitted to it from user equipment to read the stored encrypted private key and the public key of the user. The encrypted private key is then transmitted via the network to the user equipment and, locally, at the user equipment the received encrypted private key is decrypted using the user identifying key. The user identifying key may be determined at the user equipment by hashing either the user's passphrase, which is entered by the user, or the user's biometric information (fingerprint, voice print, retina scan, or face scan). The private key is sent to the user equipment only when needed and, after use, the private key and user identifying key are not retained at the user equipment.
Patent CA-2281746-A1 (CA)
Inventor: SERIES ROBERT WILLIAM
IPC: G10L15/065
Filed: 1998-02-26
Abstract: A speech analysis system (10) incorporates a filterbank analyser (18) producing successive frequency data vectors for a speech signal from two speakers. From each data vector, units (22A and 22B) produce a set of modified data vectors compensated for differing forms of distortion associated with respective speakers. A computer (24) matches modified data vectors to hidden Markov model states. It identifies the modified data vector in each set exhibiting greatest matching probability, the model state matched therewith, the form of distortion with which it is associated and the model class, i.e. speech or noise. The matched model state has a mean value providing an estimate of its associated data vector. The estimate is compared with its associated data vector, and their difference is averaged with others associated with a like form of distortion in an infinite response filter bank (48A or 48B) to provide compensation for that form of distortion. Averaged difference vectors provide compensation for multiple forms of distortion associated with respective speakers.

Abstract: The game of Dunjo Ball is played within a rink (see diagrams) which can be fabricated of any material that is most cost efficient and that will produce the proper bounce. The game is played with replacement blades for aluminum hockey sticks and a small plastic ball, similar to a ping pong ball. At each end of the rink, their are two nets. The players sit on chairs behind the nets, with their legs placed over the crossbar and their feet inside the rink. The nets are cut down lower then the boards, so the player can slide in comfortably (see diagrams). The object of the game is for both players to defend their nets using their hands and legs without leaving their seated position, while trying to score on the opposition by hitting the ball with the blade into the opposing net (see specifications). Dunjo ball can also be played with four people, team play. The two extra players in this variation of the game, sit behind the side boards across from each other and are only allowed to have their blades inside the rink. Their feet must stay on the outside of the rink. The wingers, as they are called , must also stay seated like the goaltenders. Extensions to the sideboards are added, making the rink longer for team play. A slot is also cut into the top of the extension to allow the wingers greater comfort and mobility (see diagrams). Both the goaltenders and the wingers can score and pass to each other (see specifications). There is also various other ways of playing the game listed in our specifiactions or the players can invent their own. The rules and regulations of Dunjo Ball are listed in the specifications section. Dunjo Ball is intended to be a combination of ping pong and hockey. It is fast paced and exciting to play. The plastic ball can be passed and bounced of the boards which create the speed and intensity of the game. Dunjo Ball gets faster and faster as the players get better. The game is excellent for improving reflexes, hand eye coordination and concentration. Dunjo ball can be played and enjoyed by children and adults alike.

Title: Methods and apparatus for controlling communications networks supporting layer 3 services
Inventor: YOUNG GEORGE R
IPC: H04L29/06
Filed: 1999-09-27
Abstract: In methods and apparatus for controlling a communications network supporting a Layer 3 service, data characterizing activity of the network both in Layer 3 and in at least one Layer below Layer 3 is collected. The collected data are processed to determine that a reconfiguration of the at least one Layer below Layer 3 is favourable, and to determine a favoured reconfiguration of the at least one Layer below Layer 3. Implementation of the favoured reconfiguration is initiated. The Layer 3 service may be a packet data service, such as Internet Protocol service, and the layers below Layer 3 may include an optical transport layer which is reconfigured based on processing of data collected from both the optical transport layer and the packet data layer. Rapid reconfiguration of the optical transport layer according to data collected from both the packet data layer and the optical transport layer reduces over-provisioning of the network needed to meet difficult-to-predict traffic patterns and loss of revenue due to inability to serve traffic with the current network configuration. A Fuzzy Logic control algorithm is described.

Title: Method and device for impregnating fiber bundles with resin
Inventor: ANDERSON ROGER A
IPC: B29B15/12
Filed: 1998-06-22
Abstract: Resin impregnation of fiber bundles for use in making a composite material is described. The improvements of the disclosed method and impregnation head enable high fiber take-off speeds without excessive damage or fraying of the fiber bundles. Encapsulated air or voids in the impregnated product are consistently less than 1 % by volume of the impregnated product and decrease with increased take-off speed. These improvements are achieved by passing the fiber bunbles (40) through a multi-chambered impregnation head (10) in which the resin is injected into a downstream chamber (28). The cross-sectional area of the fiber bundles, the velocity of the fiber bundles, the size of the openings to the chamber, the viscosity of the resin and the pressure at which the resin is pumped into the downstream chamber all control the pressure within the downstream chamber. The pressure is adjusted so that the resin flows upstream against the movement of the fiber bundles and sets up a wall of resin in the upstream chamber (26).  The wall of resin minimizes the air that is encapsulated with the resin and prevents air from entering the downstream chamber. The pressures and counter flow of resin within the impregnation head drives encapsulated air out of the resin.

Patent CA-2301825-A1 (CA)
Title: Optical amplifier having substantially uniform spectral gain
Inventor: SRIDHAR BALAKRISHNAN
IPC: H04B10/17
Filed: 1999-05-18
Abstract: An optical amplifier is disclosed having substantially uniform spectral gain.  The amplifier comprises a variable optical attenuator coupled between first and second segments of active optical fiber. The attenuation of the optical attenuator is adjusted in accordance with the optical power input to the amplifier to thereby obtain substantially flattened gain. Alternatively, the attenuator can be controlled based on the respective gains associated with the first and second segments of optical fiber. For example, the attenuator can be adjusted so that the sum of the two gains remains substantially constant, a condition that also yields flat spectral gain. Further, optical powers associated with first and second wavelengths of amplified stimulated emission (ASE) light output from the amplifier can be used to adjust the attenuation of the optical attenuator. In an additional example, received optical powers associated with each of the channels in a WDM system are monitored and the attenuators within each amplifier in the system are controlled so that the received powers are substantially equal.
