Patent CA-2296330-A1 (CA)
Inventor: MURRIN PAUL
IPC: G10L13/04
Filed: 1998-07-31
Abstract: A method of generating a message having an invariable por-tion (U1) and a variable portion (V) is provided. Most of the in-variable portion (U1) is provided in the form of recorded speech (A) whereas the variable portion (V) is provided in the form of syn-thesised speech (B). The synthe-sised speech (8) also extends by half a phoneme into the invari-able portion (U1) of the message.  The synthesised speech (B) and the recorded speech (A) are then con-catenated, with a transition signal being formed on the basis of a boundary portion of each of the recorded (A) and synthesised sig-nals (B) about any join (8). In forming the transition signal, a set of transition signal pitchmarks is created and an overlap-add tech-nique is used to copy the wave-form within the boundary portions of the speech signals (A, B) around the transition signal pitchmarks.  The signal around the penultimate pitchmark in the leading boundary portion is copied to the trailing half of the transition signal and the signal around the second pitchmark in the trailing boundary portion is copied to the leading half of the transition signal. In this way, the characteristics of the generated message around the join (8) change gradually between the characteristics of the recorded speech (A) and the characteristics of the synthesised speech (B).

Title: System and method for establishing a communication connection
Inventor: SHIELDS JAMES
IPC: H04L29/08
Filed: 1998-08-05
Abstract: Narrowband subscriber terminals (40, 52, 58) of different narrowband networks are interconnected via a broadband network (48) that supports dissimilar signalling protocols to those maintained on the respective narrowband networks (40, 52, 58). A call server in a first narrowband network (40), in response to a call (100) from a first subscriber terminal (12) to a second subscriber terminal (68) in a second but different narrowband network (52), selects a phantom trunk (202) between the two networks. The phantom trunk has a unique circuit identity, which circuit identity is used in a first instance to relay to the second network an address of the second subscriber terminal (68). Then, in a second instance, the unique circuit identity is used to relay to the second network an address of the first subscriber terminal (68). By recognising that two connection requests have been received at opposite ends of the same phantom trunk, a processor in the second network is able to determine that a direct connection between the first and second subscriber terminals is required through the broadband network (48).

Patent CA-2303754-A1 (CA)
Inventor: PRAVDA LIVIA
IPC: F03B13/18
Filed: 2000-04-03
Abstract: The essence of the invention is how to "catch" the energy of the waves, how to rationally transmit it to the shore and transform it into a useful energy (current). The first problem is solved with a specially designed floating vessel that with its resistance takes over the energy of the waves as much as possible. The transmission is solved by insertion of particular truss beams, that multiples the energy which has been taken over in a ratio L1 :L2, and transfers it to the converter. The transformation of the energy into the rotation is performed by the hydraulics; this mechanism provides the hydraulic engine to rotate into the same direction. The electric generator is directly connected to the axis of the hydraulic engine. The whole system is solved simply, without complex constructional structures, so the expenses of the exploitation, maintenance, and the investment in particular, are meaningless, in regard to the classical solutions (thermal plants, hydraulic plants, and nuclear plants). There is no need to mention the ecological advantages; this energy is at disposal in abundance.

Patent CA-2310220-A1 (CA)
Inventor: ARPAIA DOMENICO
IPC: H04W88/06
Filed: 1998-11-05
Abstract: L'invention porte sur une signal étroit à large bande tel qu'un signal MF modulé par un modulateur qui module un signal large à large bande tel qu'un signal AMDC (accès multiple par différence de code) par suréchantillonnage du signal étroit et par application du signal étroit suréchantillonné sur le modulateur. En suréchantillonnant le signal étroit à large bande, on peut utiliser le même filtre passe-bas fixe pour le signal large et pour le signal étroit suréchantillonné. Il n'est donc pas nécessaire d'utiliser différents filtres passe-bas ou des filtres passe-bas commutés. Le décalage du niveau continu qui est introduit par le numériseur et/ou par le filtre passe-bas du modulateur est compensé, de préférence dans le domaine numérique, de façon à réduire ce décalage dans les limites acceptables de la modulation utilisée. De préférence, on effectue une compensation en soustrayant du signal échantillonné une valeur numérique représentant le décalage du niveau continu dans le signal analogique filtré introduit par le numériseur et/ou le filtre passe-bas. Un capteur détecte le décalage du niveau continu dans le signal analogique filtré. Un dénumériseur réagit au capteur de façon à convertir le décalage du niveau continu détecté en un signal de décalage numérisé. Un soustracteur réagit au dénumériseur de façon à soustraire le signal de décalage du courant continu du signal échantillonné et à appliquer le signal échantillonné moins le signal de décalage du niveau continu sur le numériseur.
