Title: Coding system and method for lossless and lossy compression of still and motion images
Inventor: BARTHEL KAI UWE
IPC: H04N7/26
Filed: 1998-10-28
Abstract: The invention relates to a coding system for lossless and lossy compression of still and motion images with means of statistical context modeling for adaptive entropy coding of wavelet coefficients in different conditioning templates. Furthermore it is directed to a method for lossless and lossy compression of still and motion image data by hierarchical decomposing of said image data into subbands by a revertible wavelet transform that generates wavelet coefficients and by using a conditioning template for statistical context modeling and adaptive entropy coding of said wavelet coefficients. The compression ratio is improved by one or more of the following steps: - adapting the shape and/or orientation of said conditioning template to different subbands; - converting a two-dimensional array of signed wavelet coefficients into an equivalent sequence of only two input symbols for adaptive binary entropy coding; - using previously scanned bit planes in forming conditioning templates; - reducing the number of possible conditioning states corresponding to all possible combinations of events in the conditioning templates by using least-squares estimates of magnitudes of wavelet coefficients; - reducing the number of possible conditioning states corresponding to all possible combinations of events in the conditioning templates by first using least-squares estimates of magnitudes of wavelet conditions, and then by minimum-entropy quantization of said estimates; - comparing the so-far-coded bits of the coefficient C being presently coded with the so-far-coded bits of the neighbouring coefficients and parent coefficient of C to characterise spacial texture patterns and using them to augment the conditioningstates created by the quantization of said estimates; - conditioning the sign of a wavelet coefficient C on the signs of neighbouring coefficients of C. - recording for each subband the location of the most significant bit of the coefficient of maximum magnitude in the subband and including it as side information in the code stream.

Title: Method and apparatus for dynamic and steady-state modeling over a desired path between two end points
Inventor: PICHE STEPHEN
IPC: G05B13/02
Filed: 1997-05-05
Abstract: A method for providing independent static and dynamic models in a prediction, control and optimization environment utilizes an independent static model (20) and an independent dynamic model (22). The static model (20) is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model (22) is trained over a narrow range of data. The gain K of the static model (20) is utilized to scale the gain k of the dynamic model (22).  The forced dynamic portion of the model (22) referred to as the bi variables are scaled by the ratio of the gains K and k. The bi have a direct effect on the gain of a dynamic model (22). This is facilitated by a coefficient modification block (40). Thereafter, the difference between the new value input to the static model (20) and the prior steady-state value is utilized as an input to the dynamic model (22). The predicted dynamic output is then summed with the previous steady-state value to provide a predicted value Y.  Additionally, the path that is traversed between steady-state value changes.

Title: Redundant call processing
Inventor: CHONG KOAN S
IPC: H04Q3/00
Filed: 1999-05-31
Abstract: A telecommunications network includes at least an active and a standby call server, the standby call server becoming active upon failure of the active call server. To facilitate rapid switch-over from the active to the standby call server and to prevent the loss of call processing data for calls in the call setup stage, the active call server sends call information to the standby call server during intervals in which the active call server is awaiting subsequent signaling messages from elements of the telecommunications network. In this way, the standby call server has the call information needed to commence call processing upon failure of the active call server, and the active call server makes efficient use of time while awaiting a reply signaling message.

Title: Dispositif de production d'une matiere filtrante composite et son procede de fabrication
Inventor: DUBSON ALEXANDER
IPC: B01D39/16
Filed: 1997-12-09
Abstract: On décrit un dispositif et un procédé de production d'une structure fibreuse poreuse. On produit un ou plusieurs points à forte courbure de surface dans un polymère liquéfié tel qu'une solution polymère ou qu'une fonte polymère. Pour produire les points à forte courbure de surface on peut faire passer en force le polymère liquéfié à travers des filières étroites (6) ou bien mouiller des parties nettement saillantes (40) avec le polymère liquéfié. Ce dernier est chargé jusqu'à un potentiel électrique négatif élevé par rapport à une courroie mobile (10) mise à la masse. De minces jets de polymère liquéfié sortent des points à forte courbure de surface pour heurter la courroie mobile (10) sous forme de fibres, ceci formant une structure fibreuse matissée d'une porosité relativement uniforme. Un aérosol pulvérulent est chargé jusqu'à un potentiel électrique positif élevé par rapport à la courroie mobile (10). Lorsque la courroie (10) dépasse l'aérosol, les particules de ce dernier sont attirées pour combler les interstices existant dans la structure fibreuse et on obtient de cette manière une matière filtrante composite.
