Abstract: A fire fighting installation is taught having a high operating pressure provided with a valve which is reliable without access to electric current and is of a simple structure. The valve has a spindle which is movable between a stand-by position and an activated position. A secondary liquid source with a low pressure acts on the spindle in the direction towards the stand-by position and a spring acts on the spindle in the opposite direction. When the pressure in the secondary liquid source, due to liquid delivery to a released spray head in the installation, has fallen to a predeterminable value the spring drives the spindle to the activated position and opens a direct connection from the inlet of the valve to its outlet.

Abstract: A method and apparatus are disclosed for interpolating pixels to obtain subpels for use by a video decompression processor. A prediction area is defined from which subpels are necessary to decompress a portion of a video image. Instead of reading all of the pixels from the prediction area and then processing them together to perform the necessary interpolation, portions of the pixel data are read and simultaneously averaged using in-place computation in order to reduce hardware requirements. Rounding of subpixel results is achieved using the carry input of conventional adders to add a binary "1" to the averaged pixels, which are subsequently truncated to provide the interpolated subpels.

Abstract: This invention relates to the generation of synthetic speech and specifically to the production of a digital waveform from a text in phonemes. The invention uses a linked database which comprises an extended text in phonemes and its equivalent in the form of a digital waveform. The two portions of the database are linked by a parameter which establishes equivalent points in both the phoneme text and the digital waveform. The input text (in phonemes) is analyzed to locate matching portion in the phoneme portion of the database. This matching utilises exact equivalence of phonemes where this is possible; otherwise relation between phonemes is utilised. The selection process identifies input phonemes in context whereby improved conversions are obtained. Having analyzed the input text into matching strings in the input form of the database beginning and ending parameters for the sections are established. The output text is produced by abutting sections of the digital waveform and defined by the beginning and ending parameters.

Granted: 2004-12-21
Abstract: Cette invention se rapporte à un système d'acquisition et d'audit multimédia pour réseau de surveillance vidéo, qui fournit un enregistrement inviolable et facilement visualisable de chaque transaction faisant l'objet d'une surveillance. Ce système stocke un enregistrement numérique de chaque transaction physique, enregistrée par un dispositif électronique dans un format de base de données prédéfini standard, et stocke un signal vidéo composite mixte séparé contenant à la fois un enregistrement visuel et un enregistrement numérique de chaque transaction. L'enregistrement numérique et le signal vidéo composite mixte, stockés séparément, sont mis en corrélation à l'aide d'un pointeur de système unique. Dans le mode de réalisation préféré de cette invention, ledit pointeur de système unique identifie, au minimum, le dispositif électronique qui a enregistré la transaction physique, ainsi que la date et l'heure de la transaction. Le stockage à la fois d'un signal vidéo composite mixte et d'un enregistrement numérique rend difficile toute modification non autorisée de l'enregistrement de la transaction, alors que la conservation d'un enregistrement de chaque transaction dans un format numérique donne aux utilisateurs la possibilité de compiler et d'analyser des données à des fins d'audit. Grâce à l'utilisation dudit pointeur de système unique, il est facile d'identifier et de visualiser la partie du signal vidéo composite mixte qui correspond à n'importe quel enregistrement numérique pouvant être marqué comme étant intéressant à des fins d'audit.

Granted: 2002-08-27
Abstract: A system and method which delivers data at very high data transmission speeds to many locations simultaneously. A SCANS system is supplied with a satellite uplink communication module which transmits data to an earth orbiting satellite. The satellite then retransmits the data over a wide geographical area. Each receiving location is equipped with a small satellite dish to receive data from the satellite. Advantageously, the satellite dish is connected to a work station in the switching office which then processes the received data and delivers all information in a form that is ready for use by the modules' switching office. Errors during data transmission are noted for further processing. After the data is broadcast from the beginning to the end, the SCANS system pauses for a brief interval during which time each receiving station performs error detection, error correction, and other recovery procedures on the data it just received. The SCANS system, using satellite transmission, then broadcasts data once again from the beginning to the end. Receiving stations then selectively acquire data that was missing or in error after the first transmission.
Patent CA-2198949-C (CA)

IPC: G01R31/58
Filed: 1997-03-03
Granted: 2000-07-18
Abstract: A fault indicator is described having a winding disposed on a magnetic pole assembly.  The winding delivers energy from a monitored conductor to circuitry of the fault indicator.  A series-connected threshold device, such as a four layer bilateral diode or a zener diode, precludes a capacitor from charging during normal current flow in the monitored conductor.  The series-connected threshold device, however, breaks down when a fault current flows in the monitored conductor.  After break down, the fault current charges the capacitor.  A shunt-connected threshold device, such as a zener diode, limits the voltage developed across the capacitor.  After its charging phase, the capacitor drives a multivibrator which actuates an LCD, displaying the occurrence of the fault current to an operator.  A series-connected threshold device shuts the LCD off when the voltage across the capacitor drops to a sufficiently low level.  The arrangement of these electrical components allows the operator to accurately define the duration of time in which the LCD displays the occurrence of the fault current in the monitored conductor.

Abstract: A shock strut assembly (10) for an aircraft landing gear includes a trunnion fitting (12), a compressible oleo strut subassembly (14), a wheel subassembly (16), an energy dissipating subassembly (50), and a mechanical fuze subassembly (60). The oleo strut subassembly (14) includes a cylinder member (24) having an upper end mounted in combination with the trunnion fitting (12) by means of the mechanical fuze subassembly (60). The energy dissipating subassembly (50) includes a cylindrical cutter member (52) secured in combination with the cylinder member (24) and the trunnion fitting (12) and a frangible tube member (58) mounted in concentric combination with the cylinder member (24). The mechanical fuze subassembly (60) includes a shear ring (62). During normal landings, the shear ring (62) prevents movement of the cylinder member (24) with respect to the trunion fitting (12) in a crash landing, the shear flanges (66) shear at a predetermined axial load failure limit, which allows the cylinder member (24) to be displaced relative to the trunnion fitting (12). Displacement of the cylinder member (24) causes the frangible tube member (58) to interact with the cutter member (58) to interact with the cutter member (52), causing fracturing of the frangible tube member (58) for crash landing energy dissipation.

Title: Ultra-high temperature treatment of low-fat formed meat products
Inventor: MENDENHALL VON T
IPC: A23L13/00
Filed: 1995-12-18
Granted: 2001-08-21
Abstract: A method is disclosed for preparing a surface-pasteurized, low-fat, formed meat product. The method comprises removing surface fat, bones, and gristle, and cutting the meat into pieces. The pieces are mechanically tenderized and then mixed with water, salt, and phosphate. The mixture is massaged at 0~ to 15 ~C so that fat is conducted out of the meat and deposited on the wall of the apparatus, and protein is exuded to form a sticky surface on the pieces of meat. The massaged meat is then formed into a selected shape and frozen. The shaped meat is subjected to portion control either before or after freezing.  The portions are then partially thawed, and the partially thawed portions are surface-pasteurized at ultra-high temperature (UHT), e.g. 900-1200 ~C, for a time sufficient to denature proteins, without burning, to a depth of up to about 2 mm. Grill markings are then placed on the meat. After UHT treatment the meat is refrozen, packaged in a modified atmosphere containing carbon dioxide and nitrogen gas, and stored frozen.

Title: Combining frequency warping and spectral shaping in hmm based speech recognition
Inventor: ROSE RICHARD CAMERON
IPC: G10L15/06
Filed: 1998-01-26
Granted: 2002-09-17
Abstract: Frequency warping approaches to speaker normalization have been proposed and evaluated on various speech recognition tasks.  In all cases, frequency warping was found to significantly improve recognition performance by reducing the mismatch between test utterances presented to the recognizer and the speaker independent HMM model.  This invention relates to a procedure which compensates utterances by simultaneously scaling the frequency axis and reshaping the spectral energy contour.  This procedure is shown to reduce the error rate in a telephone based connected digit recognition task by 30%.

Abstract: In order to increase the operational safety and to reduce the rope wear, hoisting/lowering apparatus comprise one or a combination of novel features: an adaptor (3) is provided in order to allow the attachment of accessories (50), preferably by insertion. Possible accessories are e.g. holders having a loop for the attachment of hooks, and single or multiple blocks for the formation of lifting blocks. Substantially, the adaptor is formed of a number of slot-shaped recesses which are transversely traversed by rod-shaped retaining elements (11,9). One of said retaining elements (9) is displaceably mounted in order to allow the attachment resp. detachment of an accessory (50). Another measure is to provide a rope stop (102) on the traction side. The rope (103) runs through the rope stop (102) and drives a knurled wheel (110). At a given rope speed, said wheel is coupled to a pivotable brake appendix (118) by means of a centrifugal coupling (113, 115). The rope (103) is then squeezed and blocked between said appendix (118) and a counterpart (108). A third measure consists in providing guiding rolls (36, 37) in order to ensure a spiral-shaped travel of the rope (103) which is free of crossings.
