Patent CA-2411883-A1 (CA)
Title: Geared drive ring coupler
Inventor: YUAN JING
IPC: F16H9/10
Filed: 2001-05-11
Abstract: The invention comprises a geared drive ring coupler. The geared drive ring coupler comprises two pairs of adjacent drive rings (1, 2, 3, 4) rotatably connected to each end of a frame (5). Each pair of drive rings (1, 2, 3, 4) is meshed together with the cooperating pair of drive rings (1, 2, 3, 4) on the opposing end of the frame (5). The relative spatial arrangement of the axis of rotation of each set of drive rings (1, 2, 3, 4) is maintained by the frame (5), which in turn holds the drive rings (1, 2, 3, 4) in a predetermined relationship between the pulley sheaves. The drive rings (1, 2, 3, 4) on the driver pulley turn in the same direction as the driver pulley through frictional contact with the sides of the CVT driver pulley sheaves. The drive rings on the driven pulley side rotate in the opposite direction to the drive rings on the driver pulley, since they are meshed together. The driven drive rings (1, 2, 3, 4) are then in frictional contact with the sides of the driven pulley sheaves, thereby driving the driven pulley. The effective diameter or radius of each pulley is adjusted by movement of the pulley sheaves. Movement of the pulley sheaves causes the axis of rotation of each set of drive rings (1, 2, 3, 4) to move eccentrically with respect to the axis of rotation of their respective pulley. Since the drive rings (1, 2, 3, 4) are mechanically connected, the drive rings (1, 2, 3, 4) move with the frame (5) as a unit in response to the movement of the pulley sheaves, thereby changing the effective gear ratio of the transmission.

Patent CA-2420776-A1 (CA)
Inventor: GREEN JOHN H
IPC: G06F9/44
Filed: 2003-03-04
Abstract: In one aspect of the present invention a framework is presented for the generation and execution of code performing conversion to and from an arbitrary native or "wire" data format. The code facilitates a business application using a service provided by a service implementation in accordance with a native language of the implementation which may be different from the language of the business application. The main components of the framework include a model of the information necessary for the formatting of data which may be represented through the extensions to WSDL; a tool time support environment providing structured support for the generation of format handlers; and runtime support for the generated format handlers. In an alternative to this static invocation model, a dynamic usage scenario provides for invocation of format handlers dynamically obtained from a format handler factory. In both cases, the runtime uses a lazy approach to the conversion to and from the native format for improved performance. The framework is particularly suited to resource adapters for adapting an EIS service implementation for use with a business application desiring a service from the EIS.

Title: System and method for ordering and delivering media content
Inventor: CHRISTENSEN KELLY M
IPC: H04N7/173
Filed: 2001-09-13
Abstract: An Automatic Purchase System (APS) provides a radio broadcast listener with the ability to conveniently purchase media content such as music or speech while listening to the radio. The user can respond to items in the radio broadcast such as advertisements, fund raising drives such as those conducted by public radio, or interactive listener polls during the broadcast. Data such as song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored, can be transmitted using the RBDS/RDS data stream. A reference number representing song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored can also be employed for ease of implementation. This reference number can reside in a lookup table to be accessed by the APS server software on a Data Server located at the broadcast site, a remote site or both for purposes of redundancy. Transmission of purchase requests from a Technology Enabled Radio (TER) is provided via wireless transmission, or by accessing the Internet using a personal computer or through a cellular or wireless phone.

Filed: 2001-09-20
Abstract: La présente invention concerne un dispositif de réseau de diffraction de guide d'onde optique dans lequel un réseau de diffraction par modulation d'indice de diffraction est placé sur une longueur prédéterminée dans la direction de propagation de la lumière le long d'un guide d'onde optique. La lumière dans une bande de réflexion située hors de la lumière propagée à travers ce guide d'onde optique est sélectivement reflétée par le réseau de diffraction. Cette bande de réflexion est divisée en K (K bandes de longueur d'onde). La modulation d'indice de réfraction .DELTA.nall dans la longueur prédéterminée est la somme des modulations d'indice .DELTA.nk (k = 1 à k) de réfraction des périodes .DELTA.k correspondant aux k bandes de longueur d'onde. Au moins une paire de phases en dehors des phases .phi.k (k = 1) de la modulation d'indice de diffraction .DELTA.nk en position centrale de la longueur prédéterminée sont différentes l'une de l'autre. On obtient ainsi un dispositif de réseau de diffraction de guide d'onde optique qui est court dans son ensemble, fabriqué à faible coût, et ce dispositif possède d'excellentes caractéristiques de réflexion/transmission.

Title: Methods for authenticating potential members invited to join a group
Inventor: WHEELER GRAHAM A
IPC: H04L29/06
Filed: 2003-03-28
Abstract: Disclosed are methods for an invitee to gain admittance to a group. An inviter already in the group and the invitee share a secret password. The inviter uses the password to create an invitation and then issues the invitation to the invitee and to an authenticator. The authenticator creates a challenge key and challenge value and sends the challenge value to the invitee. Using the password and information from the invitation, the invitee recreates the challenge key, uses the challenge key to derive a response value from the challenge value, and sends the response value to the authenticator. The authenticator compares the response value with an expected value and, if they match, knows that the invitee must have been able to recreate the challenge key. The authenticator trusts that this invitee must be the one for which the inviter issued the invitation and admits the invitee to the group.

Abstract: A frequency domain based method using matrix rank reduction for removing noise from seismic data sets is provided using a variety of 3D eigen filtering techniques. A rank reduced grid of traces or proxy cube that is representative of an original grid of Traces, but that has a better signal to noise ratio results since the surviving data elements represent the bulk of the composite signal related to genuine reflectors - whereas the trivial elements replace a large portion of the composite signal related to random noise. There is no compression of the elements of the representative matrices. The use of a series of proxy cubes in place of the co- ordinate pair related original CUBEs of seismic data results in several advantages including reduced processing time and better accuracy at the boundaries of the subject section.
