Filed: 2000-01-07
Granted: 2004-11-02
Abstract: A delta sigma modulator which uses at least one quantizer having a dead zone, The dead zone quantizer outputs a zero when its input is within the dead zone range, It outputs a predetermined value if the input is above the dead none range. If the input is below the dead zone range, the quantizer outputs another predetermined value. Ideally, the quantizer dead zone thresholds are complimentary in that the upper threshold for an input is the positive value of the lower threshold. Also, to save on accumulator bits, the delta sigma modulator selects a predetermined number of most significant bits at different stages.

Title: Method and apparatus for a conference call mediation service
Inventor: MEIER-HELLSTERN KATHLEEN S
IPC: H04L29/06
Filed: 2000-03-14
Granted: 2005-08-02
Abstract: A method and apparatus for a conference call mediation service which allows for the scheduling of multi-participant conferences over the Internet is presented. A subscriber who desires to host a conference sends a conference request to a Web Service Control Point (WSCP) with attributes regarding the conference (i.e., date, time, conference agenda, etc.). The WSCP generates a unique conference ID, identifying the attributes of the proposed conference, and broadcasts a conference invitation to potential conference participants.  Potential participants respond to the conference invitation and may make changes to, or modify, the attributes of the proposed conference. The WSCP acts as a negotiator between potential conference participants by continuing to resend the modified and unmodified conference attributes until an agreement regarding the conference is reached. At that point the WSCP schedules the conference with a communication service provider ant sends a confirmation to each participant.

Abstract: In the present invention, there is provided an ice skateboard comprising a bottom surface and trucks and axles mounted to the bottom surface. A set of runners is pivotally mounted to the axles. Each of the runners has a solid body, a bearing assembly, a metal blade mounted to the solid body and a center of gravity between the bearing assembly and the metal blade. The maximum radial dimension of the runner about the bearing assembly is smaller than the distance of the axle from the bottom surface of the skateboard such that each runner is free to rotate about one of the axles to recede against the board. In another aspect, the metal blade of each runner is mounted in a channel and a cushion strip is mounted between the metal blade and the bottom wall of the channel for absorbing a vertical movement of the blade.

Title: Method and access means for determining the storage address of a data value in a memory device
Inventor: JOHNSSON STEN EDVARD
IPC: G06F17/30
Filed: 1999-03-11
Granted: 2005-12-27
Abstract: The invention relates to a method and an access means for determining the storage address of a predetermined data value in a memory device. The data values are stored in an increasing order sequentially in a column direction according to a binary tree data structure. A new subtree root node is calculated from the previous leaf node address when the data value to be searched is not located in the previous subtree. Since a new subtree root node is always calculated from a previous leaf node address and the comparison result between the searched and read out value, the number of row address changes can be kept t o a minimum whilst a high speed for the subtree searching is maintained. The search method and the access means is memory efficient since no pointers are used and fast, since the address of a next memory location to be investigated can always be calculated from the previou s address and the last comparison result.

Abstract: The apparatus and the process are used for recovering an oil-enriched product from oil-bearing material or materials, such as tar sands. The oil-bearing material is mined using a mining equipment and is sent into the apparatus where an optimum amount of oil-enriched product is removed therefrom. Unlike conventional technologies, only a relatively small amount of solvent is used and most of it is recycled back into an earlier stage of the process. The process does not need a tailings pond since the tailings are substantially dewatered at the end of the process. Further, the tailings are deposited in an adjacent area once they come out of the apparatus. This significantly reduces the material handling and transport undertaking, thereby allowing the process and the apparatus to be operated at substantially lower costs compared to conventional technologies.
