Abstract: A method of and apparatus for matching a rate of data bits, in a matrix of data bits interleaved by a predetermined interleaving process, to a desired rate by deletion of redundant data bits or repetition of data bits derived from the matrix, includes steps of determining in a non-interleaved matrix of the data bits a pattern of bits to be deleted or repeated to provide the desired data rate, decoding an address of each bit in said pattern in a manner inverse to the interleaving process to produce a respective address of the bit in the matrix of interleaved data bits, and deleting or repeating the respective bit in the interleaved data bits in dependence upon the respective address. The address decoding is performed in the same manner as a coding of addresses for producing the interleaved data bits from the non-interleaved matrix of the data bits. The specification also discloses an advantageous interleaving process for channel interleaving in a 3rd generation CDMA wireless communications system, a shuffling method for a second stage of interleaving in such a system, and how the rate matching can be conveniently applied to turbo-coded data coded.

Abstract: An adaptive gain control system and related operating method for digital audio samples is provided. The method is suitable for use with a digital media encoding system that transmits encoded media streams to a remotely-located presentation device such as a media player. The method begins by initializing the processing of a media stream. Then, the method adjusts the gain of a first set of digital audio samples in the media stream using a fast gain adaptation scheme, resulting in a first group of gain-adjusted digital audio samples having normalized volume during presentation. The method continues by adjusting the gain of a second set of digital audio samples in the media stream using a steady state gain adaptation scheme that is different than the fast gain adaptation scheme, resulting in a second group of gain-adjusted digital audio samples having normalized volume during presentation.

Filed: 2010-09-23
Abstract: A method and apparatus for determining a range within a wireless communication system is provided herein. The range information can then be used to locate a node (e.g., an asset tag). During operation, the minimum transmission power of a source transceiver (e.g., an RFID reader) that enables a tag to be detected will be used to indicate distance. Changes in transmit power will be used to indicate relative changes in distance to a particular node. The reader will be configured to always operate at a transmission power that will result in a certain percentage (e.g., 50%) detection rate for a target transceiver (e.g., an RFID asset tag). As the reader moves closer to the tag, the minimum detection power will decrease; as it moves farther from the tag, the minimum detection power will increase. This information is displayed to give a general change in range information between the RFID reader and the asset tag (e.g., increasing range or decreasing range). An individual will be able to easily locate the asset tag by using the displayed information.

Filed: 2010-11-22
Abstract: Any of various comparisons of computer folders from different points in time is performed. Such comparisons provide the ability to discover missing documents or documents with modification dates that have changed when there would otherwise have been no need to change them and thus allows discovery of missing documents to discover fraud or to search for evidence after a fraud is suspected. In another embodiment, deltas in accounting system vendor invoice accounts are compared at different points in time, potentially exposing the practice of moving fraudulent vendor transactions into a large group of legitimate transactions for a legitimate vendor. Per period transaction totals for specific periods for legitimate vendors are compared over historical time for suspicious activity. A comparison of reports from the two different periods, using exact data and software from those separate periods (instead of reporting from "current" data), may raise a red flag otherwise missed.

Patent CA-2785054-A1 (CA)
Title: Easing pressure oxygen-dissolving device
Inventor: CHEN JIAN AN
IPC: B01F3/04
Filed: 2009-12-25
Abstract: A easing pressure oxygen-dissolving device includes a container (10) in which at least one of wavy layers (20) for gas exchanging is arranged. Each of wavy layers (20) is provided with at least one oxygen storage exchange trough (E,F,G,I,J,K,L) for gas exchanging and a water inlet (A) for injecting water into the container (10) is arranged on the upper part of the container (10). On the lower part of the container (10), there are arranged a water outlet (B) for draining water out of the container (10) and a gas inlet (C) for injecting pure oxygen into the container (10). Oxygen enters the container (10) through the gas inlet (C) on the lower part of the container (10), and fills each oxygen storage exchange trough (E,F,G,I,J,K,L). When the entering oxygen arrives at a determinate pressure, water enters the container (10) from the water inlet (A) on the upper part of the container (10), and flows through, layer by layer, the air chambers of the oxygen storage exchange trough (E,F,G,I,J,K,L) filled with oxygen, so that, at this time oxygen can be naturally dissolved into water. As the pressure makes the quantity of dissolved oxygen increase largely, aqueous solution with high dissolved oxygen can be obtained when the water inlet (B) on the lower part of the container (10) is opened afterwards.
