Abstract: Method and apparatus for signal reflection removal, such as echo cancellation, is described. Signal samples are delayed.The delays allow burst processing of consecutive samples of transmitting and receiving signals in a communication network, such as in a telephone communication system. As a result, there is tremendous reduction of memory bandwidth when compared to conventional sample-by~sample processing of signals. Echo cancellers described herein can be implemented in an FPGA. Echo in over a thousand channels can be cancelled using an FPGA and an external memory device. In embodiments for reflected signal cancellation, multiple stages of echo estimation are used.

Title: Copy protection for transmission of information
Inventor: HEYLEN RICHARD A A
IPC: G11B20/00
Filed: 2004-02-19
Granted: 2012-07-31
Abstract: It is proposed to copy protect data files for transmission by incorporating DSV data patterns, that is, data patterns which are difficult to encode without causing DSV problems, in the data files. The data in five audio streams and two video streams is placed, by way of encoders (10) and a multiplexer (12) into a stream of blocks of encoded data in the MPEG file format (14). In this format, blocks of video data V are arranged alternately with blocks of audio data A and padding stream blocks P. DSV data patterns (16) are incorporated into the MPEG file (14) by way of an encoder (18) to produce the copy protected data file (15). The DSV data patterns (16) are incorporated into locations within the MPEG file which have no data content such as padding stream blocks P and/or into unused audio data blocks A. The DSV data patterns incorporated within the data blocks fed either to a monitor or to a reproduction system will not interfere with the reproduction such that unfettered access is provided to the transmitted information. However, a CD or DVD writer will generally be caused to write a disc which, when read, will result in a reader returning corrupted data or information signalling a read error. Thus, the data in the MPEG file (14) has been copy protected.

Abstract: A method for heat treating lignocellulosic material with a water-soluble preservative, such as preferably borate, involves the modification of the lignocellulosic material by heat to a moisture content of 0 to 5%, and preferably as close as possible to 0%. The thermo-treatment of the lignocellulosic material drives out not only free extracellular water but also the intercellular and intracellular water. The process of modification by heat effectively kills the cells, permanently altering their cellular structure, and locking or fixing the preservative in the lignocellulosic material so that the water-soluble preservative does not leach out of the treated lignocellulosic material in the presence of rain water.
