Patent CA-2273660-A1 (CA)
Inventor: RHODES STEVEN JAMES
IPC: H04M3/533
Filed: 1999-06-07
Abstract: The invention provides an adapter card for use with a computing apparatus executing in a multitasking environment program elements that implement call-related functional units requiring DSP (Digital Signal Processor) resources. In a specific example, the call-related functional units provide voice recognition services, IP (Internet Protocol) telephony and voice message, among others. The adapter card includes a switch that receives voice signals from one or more telephone lines physically connected to the adapter card. A digital signal processor is provided on the adapter card and can receive an audio signal from the switch for processing. When anyone of the call-related functional units needs access to the resources of the DSP, it issues a control signal to the switch that responds by directing the audio signal that is to be processed by the call-related functional unit to the digital signal processor. The results of the manipulations performed by the digital signal processor on the audio signal are then transferred to the call-related functional unit for further processing. The invention also provides a method and apparatus for processing calls implementing the above-functionality, and a digital signal processor featuring a switch capability coupled to a time-shared DSP resource.

Title: Track transport system with support bracket and track-traveling apparatus
Inventor: NOLES LARRY J
IPC: A62B35/04
Filed: 1997-11-24
Abstract: A cable (31) or other track (31) is supported at points along its length by track support brackets (20) that define and shape the course of the track (31), providing corners, curves, and other direction changes. A tracktraveling element (40) is provided that can travel along the track (31) unimpeded by the track supports (20). The track support (20) and the tracktraveling elements (40) can pass by the track support brackets (20) without manipulation. The track support has an arcuate arm (23) having a center of curvature and an arm radius defining a circular segment. The track-traveling element (40) has a passageway surrounding the track, a pivoting axis, and a slot (43) communicating with the passageway. The slot (43) is spaced from the pivoting axis by a distance substantially equal to the arm radius of the track support (20). The pivoting axis and the arcuate arms (23) center of curvature are arranged to be coincident within a predetermined tolerance, so that the slot (43) passes the arcuate arm (23) despite pivoting of the track-traveling element (40) throughout a substantial range of angles about the pivoting axis. The system can be used for various purposes including carrying loads in a conveyor system, protection of a worker in a fall-arrest system, controlling an animal in an animal-tethering system, and supporting and guiding draperies.

Title: Distributed agreement on processor membership in a multi-processor system
Inventor: BASAVAIAH MURALI
IPC: G06F11/14
Filed: 1998-01-23
Abstract: A system to determine the group of processors that will survive communications faults and/or timed-event failures in a multi-processor system (100). The processors (112), each having a memory (118) and connected to an inter-processor communication network (114), detect that the set of processors with which they can communicate has changed. They then choose to halt or continue operations based on minimizing the likelihood that disconnected groups of processors will continue to operate as independent systems on the initiation of a regroup operation (622b). A processor is suspected of having failed when other processors detect the absence of a periodic message from the processor (682). When this happens, all of the processors are subjected to a series of stages in which they repeatedly broadcast their status and connectivity to each other (830). The suspected processor does not advance through the stages to regroup if it has ceased operations or if its timer mechanism has failed.

Patent CA-2278183-A1 (CA)
Title: Communications network
Inventor: HUNT ROWLAND GEOFFREY
IPC: H04M3/42
Filed: 1998-01-14
Abstract: In a communications network, a count (82) is maintained of the number of calls made to a selected number. The number may be that of an answering centre (6) or of any other destination which has the capacity to handle a multiplity of calls simultaneously. The count is automatically updated when calls are admitted to the number and when they are terminated. If a new call would take the number of calls in progress above a stored value for the maximum capacity of the number, then the call is rejected. In one implementation, resources are allocated dynamically on an Overload Control Server (66) to a particular destination number only when congestion occurs.  The stored value for the capacity may be amended automatically depending on the response of the network to admitted calls. The value for the capacity may initially be estimated as a function of the holding times for calls to the destination number.

IPC: A61K31/05
Filed: 1997-09-05
Abstract: On a découvert que la stimulation des récepteurs .beta.-adrénergiques, lesquels activent la formation de cAMP, induit une synthèse accrue de APP et de GFAP dans des astrocytes. En conséquence, l'exposition in vitro ou in vivo de cellules neuronales à certaines compositions comprenant des ligands ou agonistes du récepteur .beta.-adrénergique, notamment par exemple la norépinéphrine, l'isoprotérénol et analogue, augmente la transcription par l'ARNm de APP et, par conséquence, une surproduction de APP. Ces augmentations sont bloquées par des antagonistes du récepteur .beta.-adrénergique, tels que le propanolol. Le traitement in vitro ou in vivo de ces cellules à l'aide de 8Br-cAMP, de prostaglandine E¿2? (PG E¿2?), de forskoline et de ditartrate de nicotine, augmente également la synthèse de APP, avec notamment une augmentation des taux d'ARNm et d'holoprotéines, de même qu'une augmentation de l'expression de la protéine acide fibrillaire gliale (GFAP). On décrit des compositions et procédés destinés à réguler une surexpression de APP et à induire une astrogliose réactive via une signalisation de cAMP ou l'activation des récepteurs .beta.-adrénergiques. On a encore trouvé que l'augmentation de la synthèse de APP, provoquée par 8Br-cAMP, PG E¿2?, la forskoline ou le ditartrate de nicotine, était inhibée par des immunosuppresseurs ou des agents anti-inflammatoires, tels que la cyclosporine A et FK-506 (tacrolimus), de même que par des modulateurs des canaux ioniques, notamment des agents de chélation d'ions tels que EGTA, ou des inhibiteurs de calcium/calmoduline kinase, tels que KN93. La présente invention a des incidences importantes sur le soulagement, le traitement ou la prévention des troubles neurologiques et des maladies neurodégénératives, notamment la maladie d'Alzheimer.
