Title: Micromechanical electrostatic relay, and a method for its production
Inventor: KIESEWETTER LOTHAR
IPC: H01H59/00
Filed: 1998-07-24
Abstract: The micromechanical relay has a base substrate (81) on which a flexible induction tongue (41) with a moveable contact (8) is structured in such a way that it is elastically curved away from the substrate in non-operational mode. A fixed contact (7) interacting with the moveable contact is arranged on a fixed contact flexible tongue (42) that is also curved away from the base substrate, so that the open ends of both flexible tongues face each other and the moveable contact (8) overlaps the fixed contact. By arranging the contacts on two flexible tongues, a relatively high extra way of contacts is achieved throughout the entire stretched position despite a possible low inductive path using an electrostatic driving system, thereby enabling sufficient contact force to be generated.
Patent CA-2301621-A1 (CA)
Inventor: VACHRIS PAUL F
IPC: G06K9/00
Filed: 1998-08-31
Abstract: A device for imaging a relief object without illuminating a platen is disclosed. The device includes a single electrode electroluminescent device (12), which may be inorganic or organic, and a current source (14). The current source (14) is coupled to the single electrode (22) of the electroluminescent device (12) and to the relief object (20) to be imaged. The valleys and ridges of the relief object couple current to the electroluminescent device at different magnitudes which causes the electroluminescent device (12) to generate light at different intensities that correspond to the ridges and valleys of the relief object (20). The generated light forms an image of the relief object (20) which may be focused by optical elements onto a sensor array for capture and image processing. In another embodiment of the invention, a one-to-one sensor array is located proximate the electroluminescent device (12) to capture the image. In an embodiment of the invention which insulates the relief object (20) from current, the electroluminescent device (12) is covered with a variable resistance layer and the variable resistance layer (44) is covered with a flexible electrode (46).  One lead from the current source (14) is coupled to the flexible electrode (46) and another lead is coupled to the single electrode (22). When a relief object (20) is brought in contact with the flexible electrode (46), localized pressures generated by the ridges of the relief object (20) form conductive paths through the variable resistance layer (44) which are lower in electrical resistance than those formed by pressure in the areas adjacent the valleys of the relief object (20). The different magnitudes of current delivered through the conductive paths to the electroluminescent device cause the electroluminescent device to generate an image of the relief object without exposing the relief object (20) to electrical current.

Patent CA-2306305-A1 (CA)
Title: Optical attenuator and method of making same
Inventor: KAWASAKI BRIAN S
IPC: G02B26/02
Filed: 2000-04-20
Abstract: A compact, tunable, wavelength independent, all-fiber attenuator is produced by heating a single-mode fiber to create at least a section of optical fiber having an expanded mode field therein. The attenuator may be tuned to achieve the desired value of attenuation and wavelength independence by imparting a small bend to the section having an expanded mode filed. An expanded mode field section can be achieved in ways other than heating the fiber, however using an optical fibre having a thermally expanded core section is preferred. The attenuator may be a fixed value attenuator or a variable attenuator. When a fixed value attenuator is desired, the expanded core section is bent suitably and the structure is encapsulated in an adhesive and glued onto a substrate. The mode field of the expanded core optical fibre should have substantially no attenuation when the expanded mode field portion of the optical fibre is un-bent.

Title: Method of calibration and real-time analysis of particulates
Inventor: MOSHE DANNY S
IPC: G01N21/64
Filed: 1999-08-25
Abstract: A method of analyzing particles for chemical or biological species. Spectral images of the particles are acquired (24, 46). Targets are identified in the images and are classified (52, 80) according to morphology type (78) and spectrum type (76). A descriptor vector (58, 88) is formed and transformed to a vector of mass concentrations of chemical species of interest, or of number concentrations of biological species of interest, using a relationship determined in a calibration procedure. In the calibration procedure, spectral images of calibration samples of known composition are acquired, and empirical morphology types and spectrum types are inferred from the spectral images. Targets are identified in the spectral images and classified according to morphology type and spectrum type. A  calibration descriptor vector (58, 88) and a calibration concentration vector (60, 90) is formed. A collection relationship (94) between the calibration descriptor vectors and the calibration concentration vectors is found, either by multivariate analysis or by training a neural network.

Filed: 2000-06-05
Abstract: A data transmission method, a data transmission system, a transmitter and a receiver which can reduce the probability of detecting the rate mistakenly at the receiving side and can eliminate the need for providing buffer for temporarily storing the transmitted data at the transmitting side in variable rate data transmission are provided. At the transmitting side, an error-detecting code of the transmitted data is calculated, frame by frame, the error-detecting code is arranged after the corresponding transmitted data, and frame data is generated in such a way that bit arrangements of the transmitted data and of the error-detecting code are set in a reverse order to each other. At the receiving side, the transmitted data and the error-detecting code are assumed by assuming a final bit position of the frame data, frame by frame, for the received frame, data and the error-detecting code of the assumed transmitted data is calculated. Among the assumed final bit positions of the frame data, a position such where the assumed error--detecting code agrees with an error-detecting code calculated on the basis of the assumed transmitted data is determined to be the final bit position of the frame data.

Inventor: MAG TED
IPC: A61K31/122
Filed: 2000-01-28
Abstract: Triglyceride oil derived from marine sources, mammalian and fish, is treated with a silica at relatively low temperature under vacuum and is then further treated with a bleaching clay under vacuum and at higher temperature. The silica and the bleaching clay are then separated from the oil. The oil treated by this method is essentially free of proteinaceous materials, phosphatides and mucilage, pro-oxidant metals and very low in colored compounds, and is suitable for deodorizing. The deodorized oil is completely bland, unchanged in the concentration of the long-chain highly unsaturated fatty acids (EPA, DPA and DHA), very low in color, peroxides and secondary oxidation products, free of pesticides and has very good flavor stability.        The method avoids the use of any chemicals, such as in the acid and base treatments required in conventional degumming and alkali refining of oils of marine origin. This avoids the formation of artifacts in the oil and trace contamination with chemicals. It also reduces the number of process steps required to produce deodorized food oil from marine sources, which is advantageous in respect to oil quality, process losses and processing costs. The method is especially environmentally advantageous, since it avoids the need for soapstock and waste water processing entirely.     Refined oil produced by the method is useful as a nutritional supplement and in methods of therapy or medical treatment.
