Patent CA-2200933-A1 (CA)
Title: Multistage relay device
Inventor: SHIROKURA YOSHIHIKO
IPC: H04L12/70
Filed: 1997-03-25
Abstract: When a signal is transmitted from an STM line to an ATM relay channel, the signal is compressed to be cell assembled into a cell.  To the contrary, a signal from the ATM relay channel is cell disassembled into separate data and then expanded.  In cases where signals are exchanged between ATM relay channels, a multistage relay device does not repeatedly execute signal compression/expansion to the signal.  Switching for the above operations is achieved, utilizing a signal pattern inserted into audio data.  With this arrangement, an audio one-link operation is established in the environment where an STM and an ARM coexist.  Because compression/expansion processes are not repeatedly conducted, delay in relaying is avoided.

Title: Process and device for fighting fires from the air
Inventor: ROSENSTOCK WINFRIED
IPC: A62C3/02
Filed: 1996-08-13
Abstract: A container with a wall capable of bursting (in particular a drop-shaped or bubble-shaped bag made of a thin plastic film) and filled with extinguishing water is used to fight fires from the air, in particular forest fires. A  bursting charge with a fuse is arranged inside the extinguishing water. The bag is brought to the fire source by a helicopter. The bursting charge is then ignited closely above the fire source, spraying the extinguishing water into a misty cloud of microscopic droplets that abruptly extinguishes the fire source. The bag is preferably dropped by the helicopter at a higher level above the fire source and the bursting charge is ignited during its free fall shortly before the bag hits the fire source, either by remote radio control or by means of a time fuse that can be adjusted to a predetermined height. The time fuse may be activated at the same time as the bursting bag is dropped from the helicopter by an igniting source located in the helicopter and linked to the time fuse by an igniting cable that is detachable from the helicopter.

Filed: 1997-06-20
Abstract: In a DS-CDMA receiver, successively time shifted replicas of a despreading sequence are used to detect correlations with a received chip sequence and resulting correlation sequences are stored in a memory. A correlation sequence having a maximum peak and correlation sequences having side peaks inherently associated with the maximum peak are detected in the memory and all of the detected correlation sequences are removed from the memory. Following this removal, a correlation sequence having a maximum peak is detected from the remaining correlation sequences and the timing of the correlation sequence is determined. A despreading sequence which is delayed in accordance with the determined timing is produced and the chip sequence is despread with the delayed despreading sequence to produce a diversity branch signal.

Title: Stereophonic acoustic echo cancellation using nonlinear transformations
Inventor: BENESTY JACOB
IPC: H04R3/02
Filed: 1997-09-16
Abstract: A method and apparatus for estimating individual impulse responses for a stereophonic communication system, such as a teleconferencing system, which involves selectively reducing the correlation between the individual channel signals of the stereophonic system. Selective reduction of stereophonic source signal correlation advantageously results in the estimation of individual impulse responses of a receiving room of the stereophonic communication system. The selectively reduced-correlation source signals are provided to conventional adaptive filters and the receiving room loudspeakers. Automatic echo cancellation is performed in a conventional fashion, but on the selectively reduced-correlation source signals. Specifically, selective reduction of source signal correlation between two stereophonic channels of a teleconferencing system is achieved by introducing a small non-linearity into each channel in order to reduce the interchannel coherence. In accordance with certain illustrative embodiments of the present invention, each channel signal has added thereto a non-linear function of the channel signal itself, thereby reducing the interchannel coherence while preserving the quality of the signal. In one particular embodiment, the non-linear functioncomprises the half-wave rectifier.

Abstract: Méthodes de diagnostic et de soins résultant de la découverte inattendue du fait que certaines protéines antibactériennes, en particulier la lysozyme et la lactoferrine, se lient avec une forte affinité, aux produits finals de glycosylation évolués (A.G.E.) et que cette activité de liaison est essentiellement non concurrente de l'activité de liaison des hydrates de carbone bactériens aux protéines antibactériennes. L'invention porte donc sur des méthodes de traitement des pathologies liées à une augmentation des niveaux d'A.G.E. par administration d'une molécule comportant un domaine de boucle hydrophile qui est associée, dans la lysozyme et la lactoferrine, à l'activité de liaison aux A.G.E.; elle porte aussi sur des compositions comportant un tel domaine. Elle porte en outre sur des méthodes et des compositions destinées à la partition des A.G.E. d'un échantillon, et sur des méthodes d'élaboration d'un pronostic de complications liées aux A.G.E. chez un patient atteint d'une pathologie liée aux A.G.E. par mesure du taux d'activité des protéines antibactériennes, telles que les lysozymes et les lactoferrines, dans un échantillon biologique prélevé chez le patient. Une baisse du taux d'activité bactéricide des protéines antibactériennes peut être l'expression d'un accroissement du taux d'A.G.E. et un élément de pronostic de propension accrue à une infection bactérienne. Sous un autre aspect, l'invention porte sur le dépistage des A.G.E. dans un échantillon biologique. Dans certaines configurations, les A.G.E. inhibent l'activité bactéricide de la lyzozyme et de la lactoferrine, et une boucle de peptides hydrophile à 17 ou 18 acides aminés encadrés par une cystine (le premier et le dernier acides aminés sont de la cystéine formant un pont disulfure) se lie à l'albumine du sérum bovin d'A.G.E.
