Abstract: A double talk and echo path change detector is provided for use in an echo canceller that makes a determination about whether a residual signal is dominated by echo or by a "near end" signal. In order to make this determination, a first measure of linear dependency is computed between the residual signal and an echo estimate, and a second measure of linear dependency is computed between the residual signal and a desired signal. The two results are compared with each other, and if they are of about the same order, no further action is needed. However, if the comparison determines that the dependence between the residual signal and the desired signal is much stronger than the dependence between the residual signal and the echo estimate, the present detector assumes that double talk has been detected and a signal denoting that result is output. On the other hand, if the dependence between the residual signal and the desired signal is much weaker than the dependence between the residual signal and the echo estimate, the detector assumes that an echo path change has been detected and a signal denoting that result is output. As such, a reliable and computationally effective method and apparatus are provided to give the echo canceller useful information about double talk and echo path changes that have occurred.

Abstract: A method and an apparatus for the animation, driven by an audio signal, of a synthesised human face model are described, that allow the animation of any model complying with the ISO/IEC standard 14496 ("MPEG-4 standard"). The concerned phonemes are derived from the audio signal, and the,corresponding visemes are identified within a set comprising both visemes defined by the standard and visemes typical of the language. Visemes are split into macroparameters that define shape and positions of the mouth and jaw of the model and that are associated to values indicating a difference from a neutral position. Such macroparameters are then transformed into face animation parameters complying with the standard, the values of which define the deformation to be applied to the model in order to achieve animation.

Title: Method for emplacing a coil tubing string in a well
Inventor: MOFFATT TERRY GEORGE
IPC: E21B19/22
Filed: 2000-04-05
Granted: 2004-06-29
Abstract: The bottom end of a coil tubing string is secured to the bottom end of a primary tubing string at ground surface. Usually the primary tubing string will be of larger diameter and is therefore stronger and stiffer than the coil tubing string. The strings are secured together with a locking assembly. This assembly comprises two interlocking members, one connected with each string. One of the interlocking members is meltable when exposed to elevated temperature. The primary tubing string and the coil tubing string are run together into the desired position in the wellbore. The primary tubing string acts to drag the coil tubing string along with it. Heat is then used to melt the interlocking member so that the strings can be separated. The heat can be provided by circulating steam or hot water or oil down to the assembly. Alternatively the downhole formation temperature may be sufficient to induce melting. Once separated, each string can be pulled or moved independently. 10

Granted: 2007-09-04
Abstract: The present invention is directed to a fuel reformer device that produces a hydrogen rich gas from a hydrocarbon and steam. A reformer unit receives a supply of a crude fuel gas containing air through a second supply conduit. The crude fuel gas is subjected to a steam reforming reaction and an oxidation reaction proceeding inside the reformer unit. A resulting hydrogen rich gaseous fuel is discharged. The reformer unit includes an upper stream reaction unit and a lower stream reaction unit. The reformer unit is designed to enable the heat generated on the upstream side to be effectively transmitted to the lower stream side. This arrangement thus effectively prevents an excessive temperature rise on the upstream side.

Abstract: A transmitting device in a mobile communication system is disclosed. In the transmitting device, an encoder receives an information bit stream in a frame, which is as long as an integer multipl e of a predetermined value, and generates an information symbol, a first parity symbol, and a second parity symbol by encoding each information bit. An interleaver sequentially arranges the information symbols and the first and second parity symbols by rows in a n array with an integer number of rows and an integer number of columns. The interleaver reorders the columns in the array accordi ng to a predetermined rule. The interleaver further outputs a plurality of radio frames in a stream, by reading the symbols by going down each column, starting at the leftmost column and proceeding right. Each radio frame has a predetermined size. A demultiplexer demultiplexes each of the radio frames received from the interleaver into a stream of information symbols, a stream of first parity symbols, and a stream of second parity symbols. A rate matcher bypasses the stream of information symbols and punctures the streams of the first and second parity symbols for rate matching.
