Title: Spectroscopic detection of cervical pre-cancer using radial basis function networks
Inventor: TUMER KAGAN
IPC: A61B1/00
Filed: 1997-11-20
Abstract: This invention is an apparatus and methods for spectroscopic detection of tissue abnormality, particularly pre-cancerous cervical tissue, using neural networks (1000) to analyze in vivo measurements of fluorescence spectra. The invention excites fluorescence intensity spectra in both normal and abnormal tissue. This fluorescence spectroscopy data is used to train a group of neural networks, preferably radial basis function neural networks. Once trained, fluorescence spectroscopy data from unknown tissues samples is classified by the neural networks. This process is used to differentiate pre-cancers from normal tissues, and can also be used to differentiate high grade pre-cancers from low grade pre-cancers. One embodiment of the invention is able to distinguish pre-cancerous tissue from both normal squamous tissue and normal columnar tissue in a single stage analysis. The invention demonstrates significantly smaller variability in classification accuracy, resulting in more reliable classification, with superior sensitivity. Moreover, the signal stage embodiment of the invention simplifies the decision making process as compared to a two-stage embodiment.

Patent CA-2280533-A1 (CA)
Inventor: OTA JIRI
IPC: F01C21/00
Filed: 1999-08-19
Abstract: A two-stage rotary vane motor is provided that is particularly efficient for use in cryogenic refrigeration systems where the mass flow rate of the drive fluid (which may be expanding cryogen gas) varies substantially. The two-stage rotary vane motor includes a housing enclosure having first and second fluid chambers, each with their own inlets for receiving pressurized cryogen, and first and second rotors rotatably mounted within the chambers by means of a shaft assembly having an output end. In operation, when the mass flow of the drive fluid is high (350 pounds per hour), fluid is admitted through the inlets of both the chambers of the housing enclosure to drive both of the rotors. However, when the mass flow of the drive fluid drops to a low level (i.e., 100 pounds per hour), expanding cryogen is admitted only through the second chamber of the housing enclosure to drive only the second rotor. An overrunning clutch may be used to engage and disengage the first rotor from the shaft assembly in coordination with the admission of drive fluid through both or only one of the housing inlets.

Patent CA-2287816-A1 (CA)
Inventor: PHAN CAO THANH
IPC: H04L12/725
Filed: 1999-10-29
Abstract: The system evaluates the costs of different options on basis of priority of calls using routes, and resources available. The procedure provides for routing a call through a network comprising a number of nodes connected together by paths. Each call has associated with it a level of priority by means of which is it able to pre-empt communications within the network. This is based on calculation of the cost of different routes by which the call could be directed, and the choice of the route as a function of the cost. The cost of a route is a function, on the one hand of the maximum value of the communication priority on the paths of the route, and on the other hand the number of pre-empted communications on these paths and finally on the resources available on the paths.

IPC: A61M16/12
Filed: 1999-05-14
Abstract: A medical dosing device/method for providing small discrete volumes of gas, for example sulfur hexa fluoride or nitric oxide, to the breathing gases of a patient. The device includes a charging valve (3) interposed between a gas supply (1) and a dosing chamber (5). A discharge valve (8) is connected between the dosing chamber (5) and an outlet of the device (9). The dosing chamber (5) has a pressure sensor (6,7) connected to a control means (11) for the valves (3, 8). In operation, the control means (11) closes the discharge valve (8) and opens the charging valve (3) until a predetermined pressure is sensed in the dosing chamber (5). The charging valve (3) is closed and thereafter the discharge valve (8) is opened to supply gas from the dosing chamber (5) until the pressure sensed by the pressure sensor (6, 7) falls to a second, lower level. The discharge valve (8) is then closed. The gas so discharged forms the volume of gas.

Title: Process and device for the wavelength-selective mixing and/or distribution of polychromatic light
Inventor: KOOPS HANS WILFRIED PETER
IPC: G02B6/122
Filed: 1998-09-25
Abstract: The problem of the wavelength-selective mixture or distribution of polychromatic light consists, when decomposing the spectrum into several spectrally delimited light beams of minor wavelength width, which are the determinant feature of a spectrometer, in making them as easy and reliable to select as possible. When mixing polychromatic light, lights having only one wavelength are successively fed to each member of a selective chain to form a partial spectrum, and when distributing chromatic light, one wavelength is filtered out of each member and the remaining spectrum is fed after reflection to the next member for being further decomposed. A chain of photonic crystals is used both for mixing and distributing and a wavelength-selective coupler/decoupler is associated to each crystal. The fields of application of the invention are, besides the wavelength-selective mixture or distribution of polychromatic light, also spectrometric measurements and thus environment monitoring.

IPC: F17D1/00
Filed: 1999-08-06
Abstract: A method and system for detecting leaks in a fuel dispenser (12) is operative to pneumatically pressurize a selectable one of a vapor recovery portion and a fuel dispensing portion using a compressed air flow (14). A flowmeter (18) measures the flow rate of the compressed air communicated to the fuel dispenser for pressurization thereof. A processor (32) provides an indication of the leakage condition of the fuel dispenser based upon the pneumatic flow rate measured by the flowmeter (18) which satisfies a pressurization condition for the fuel dispenser, such as maintaining the pressurization level above a threshold value. The flow rate of compressed air needed to maintain this pressurization level is indicative of the leak rate.
