Title: A multiprocessor programmable interrupt controller system with processor-integrated interrupt controllers
Inventor: NIZAR P K
IPC: G06F15/17
Filed: 1994-12-21
Abstract: A multiprocessor programmable inter-rupt controller (MPIC) has a distinct three-wire interrupt bus (15) with one clock wire and two data wires for handling interrupt request (IRQ) related messages. Each pro-cessor chip (114) has an on-board interrupt acceptance unit (IAU) coupled to the inter-rupt bus (15) for the acceptance of IRQs. I/O device interrupt lines are connected to one or more interrupt delivery units (IDUs 113) that are each coupled to the interrupt bus (15). A modification to the lowest prior-ity mode arbitration procedure also provides means for uniform distribution of IRQs to eligible processors. The actual servicing of the IRQs is done by means of the system bus (110). An MPIC cluster system provides means for interconnecting individual MPIC systems into an expanded interrupt controller system whenever the interrupt handling ca-pacity of individual MPIC system (cluster) is exceeded by using a cluster manager.
Patent CA-2182962-A1 (CA)
Inventor: BRYAN-BROWN GUY PETER
IPC: G02F1/1339
Filed: 1995-01-30
Abstract: La présente invention concerne un dispositif à cristaux liquides nématiques caractérisé par deux états commutés bistables. Le dispositif comporte deux parois de cellule supportant des structures d'électrodes et renfermant une couche de matériau à cristaux liquides nématiques. Les parois des cellules sont traitées de sorte qu'un double réseau de diffraction soit formé sur l'une des parois ou les deux. Ce double réseau de diffraction est une surface d'une certaine forme permettant aux molécules de cristaux liquides en surface de s'orienter dans deux directions angulaires, par exemple à 45~ ou à 90~, à la différence des alignements de surface classiques selon lesquels les molécules de cristaux liquides en surface sont orientées dans une seule direction. Dans le cas d'une cellule à double réseau de diffraction sur chaque paroi, les sens d'alignement sur chaque paroi coïncident les uns avec les autres. Des polariseurs sont prévus devant et derrière les cellules, leurs axes optiques étant perpendiculaires à l'un des alignements commutés, et l'axe optique de l'un des polariseurs étant parallèle à ce dernier. Dans cet exemple, le polariseur émet ou bloque la lumière lorsque le matériau est commuté d'un état d'alignement à l'autre. Le double réseau de diffraction peut être symétrique ou asymétrique, et on obtient, dans le dernier cas, un certain angle d'inclinaison de la surface. Avec une inclinaison de surface appropriée pour chaque paroi de cellule, on peut donner une configuration moléculaire en évasement dans les deux états de commutation. Dans le cas des configurations évasées, la commutation électrique du dispositif peut être réalisée par couplage flexoélectrique. Dans le cas d'autres configurations, la commutation du dispositif peut se faire au moyen d'impulsions en courant continu combinées avec des ions chiraux dans le matériau à cristaux liquides. Pour réaliser le double réseau de diffraction, on utilise un procédé d'interférographie, de photolithographie, de nervurage, de traçage de lignes ou de transfert à partir d'une couche support. Un double réseau de diffraction sur une cellule peut être associé à un réseau de diffraction classique simple, ou, par exemple, à un traitement d'alignement par frottement sur l'autre paroi de cellule. Dans ce cas, le matériau conserve sa structure en hélice dans ses deux états de commutation.
Patent CA-2183317-A1 (CA)
Title: Pallet based refrigerated transportation system
Inventor: BOSHER PAUL RAYMOND
IPC: B65D19/38
Filed: 1995-02-20
Abstract: To transport and or store produce, individual refrigeration units are provided for palletised packages. A load of produce (201) is enclosed by packaging which acts as a gas barrier, e.g. a plastics bag (2), corrugated cardboard, etc. The packaging may optionally also include insulation (200). In one option the refrigeration unit is in or on the pallet (3). The gas flow across the evaporator (15) (i.e. the flow internal to the gas barrier) is kept separate from the gas flow across the condenser (10) (which flow results in heating of the ambient air) by such measures as physical separation of condenser and evaporator and ducting or channels in the pallet. In another option the refrigeration unit sits on the produce. In this case separation of the gas flows may be achieved by sealing of the barrier (e.g. clamping of the mouth of a plastic bag by an O-ring) to a flange encircling the condenser.

Title: Apparatus for managing a telecommunications network
Inventor: SHENTON PETER GORDON
IPC: H04M3/00
Filed: 1995-07-25
Abstract: A network manager for a telecommunications network has a communications stack (50) for receiving messages from the telecommunications network relating to the network elements. These messages are supplied to a message processor (52). In the message processor (52), each message is identified and parsed according to a set of rules which are established before the network manager is in operation receiving messages from the network. After each message has been identified and parsed, it is processed according to a second set of rules which can be established and modified while the network manager is in use receiving messages. The second set of rules are established from a set of prototype rules. These rules permit the user to specify a wide range of operations that can be preformed on the messages. For example, messages of specified types can be correlated, other messages can be forwarded to specified destinations, and certain messages can cause further messages to be generated. Messages can be forwarded, for example, to a configuration manager (54) or a fault manager (56) and further messages can be sent to equipment which is external of the network manager.

IPC: G01J3/02
Filed: 1997-02-07
Abstract: A high-resolution, high-throughput imaging echelle spectrograph having a long slit yields high spectral resolution and large spectral coverage simultaneously. The user is able to make quick adjustments of the desired field of view. The overlapping of different spectral orders are separated using a mosaic of interference filters which transmit approximately 50 .ANG. around the selected spectral lines. The spectra recorded by the invention, therefore, are not like any other, where wavelength increases or decreases monotonically along a given direction on an imaging detector. Instead, only selected windows about user selectable spectral regions are recorded simultaneously on the detector.
