Abstract: In a video telephony system, a coaxial cable network, which is preferably a part of an existing cable television system, provides a local link for the transmission of the video telephone signals between each originating and destination location and a respective "head end" located on the cable company premises. Each of the head ends is connected to a "point of presence" of a telephone interexchange carrier so that a connection between pairs of head ends,and thus between a pair of video telephone locations, can be made via a switcheddigital network maintained by the carrier. Certain of originating and destination locations comprise a standard television set, serving as the audio/video display, and a consumer-type camera or camcorder, serving as the audio/video source. Others of the originating and destination locations comprise ISDN video telephones which are connected to the various points of presence of the interexchange carrier via local exchange carrier telephone networks. The video telephone numbers for cable subscriber locations are administered to be the sameas the standard ten- (i.e., area code plus seven-) digit telephone numbers used for regular telephone calls directed to those locations.

Patent CA-2102393-C (CA)
Inventor: HERMANN KERSTAN G
IPC: B01D53/22
Filed: 1993-11-03
Granted: 2000-06-06
Abstract: The present invention utilizes a membrane cartridge that removes water vapor or fluid from air that passes through the cartridge. The longer the air remains within the cartridge, the more fluid is removed from the air.      Consequently, as the air becomes "drier", the dew point temperature of the air also falls. The present invention permits decreases in the flow rate and system pressure while providing dehumidified air with the desired dew point temperature. These decreases in pressure and flow rate result from increased elevation or system wear. The decrease in system pressure and flow rate increases the residence time of the air in the membrane cartridge. As a result, the dew point temperature of the dehumidified air remains stable because increased residence time increases the amount of fluid removed from the air, which tends to reduce the dew point temperature of the dehumidified air.

Abstract: A method for speaker independent isolated word recognition is based on a hybrid recognition system, using neural networks and parallel processing to give improved recognition at optimized speed and memory use, while also keeping some of the consolidated aspects of recognition techniques.  Complete words are modeled with left-to-right Markov model automata with recursion on states, each of which corresponds to an acoustic portion of the word. Recognition is obtained by performing dynamic programming according to the Viterbi algorithm on all automata in order to detect the one having the minimum cost path correspon- ding to the recognized word.  Emission probabilities are computed through a neural network with feedback, trained in an original way, with the transition probabilities being suitably estimated.

Granted: 1999-05-11
Abstract: Le Système de Propulsion Spatiale par Champ Magnétique (SPSCM) est une invention qui se distingue de part son fonctionnement et ses applications. Son fonctionnement est unique en ce qu'il fait appel principalement à deux éléments: premièrement, le SPSCM utilise des bobines de fil conducteur partiellement recouvertes de blindage magnétique à l'intérieur desquelles circul ent un courant électrique, et deuxièmement le SPSCM fait appel au champ magnétique d'un corps céleste. La c ombinaison de ces deux éléments lui permet d'obtenir une force de propulsion (translation). Le rôle du blindage magnétique est d'annuler l'action du champ magnétique à l'in térieur des régions recouvertes par le blindage. Lorsqu'une bobine est partiellement recouve rte de blindage magnétique, alors la force magnétique agit seulement sur les segments de la bobi ne non recouverts de blindage. Donc, en présence d'un champ magnétique d'un corps céleste tel le cham p magnétique terrestre une bobine partiellement blindée ressent une force de propulsion Le SPSCM tel que présenté dans ce mémoire descriptif, est composé de 24 bobines partiellement blindées. Les segments non-blindés, c'est à dire les segments permettant à la fo rce magnétique d'agir sur chaque bobine, sont géométriquement orientés de façon à obtenir instantanément e t sur commande, une force de translation dans le plan normal au champ magnétique et une force de rot ation selon les trois axes. Le SPSCM n'utilise aucun carburant conventionnel, il utilise plutôt un courant é lectrique et le champ magnétique d'un coprs céleste à titre de carburant. Cette caractérisitque combinée à l'utilisation d'un blindage magnétique distingue le SPSCM de tout autre système de propulsion spatial.
