Abstract: A capacitance transducer for use in measuring loads is provided herein. It comprises a first electrode and a second electrode having overlapping surface areas spaced apart by a first solid or rigid dielectric and a second fluid dielectric. The first and second electrodes are so oriented that increasing force which is applied to the transducer resiliently presses an increasing portion of overlapping surface areas of the first and second electrodes into close proximity separated by the first dielectric while substantially removing the second dielectric from the areas of close proximity. This causes a capacitance response that depends significantly on the size of areas which are pressed together relative to any capacitance response resulting from a change in the spacing of the electrodes.

Title: Smoke detector system with self-diagnostic capabilities and replaceable smoke intake canopy
Inventor: BERNAL BRIAN ANDREW
IPC: G08B17/107
Filed: 1994-08-17
Granted: 2000-04-04
Abstract: A self-contained smoke detector system has internal self-diagnostic ca-pabilities and accepts a replacement smoke intake canopy (14) without a need for recalibration. The system includes a microprocessor-based self-diagnostic circuit (200) that periodi-cally checks sensitivity of the optical sensor electronics (24, 28) to smoke obscuration level. By setting tolerance limits on the amount of change in volt-age measured in clean air, the system can provide an indication of when it has become either under-sensitive or over-sensitive to the ambient smoke obscuration level. An algorithm im-plemented in software stored in system memory (204) determines whether and provides an indication that for a time (such as 27 hours) the clean air volt-age has strayed outside established sen-sitivity tolerance limits. The replace-able canopy is specially designed with multiple pegs (80) having multi-faceted surfaces (110, 112, 114). The pegs are angularly spaced about the periphery in the interior of the canopy to function as an optical block for external light infil-trating through the porous side surface (64) of the canopy and to minimize spurious light reflections from the interior of the smoke detector system housing (10) toward a light sensor photodiode (28). The pegs are positioned and designed also to form a labyrinth of passageways (116) that permit smoke to flow freely through the interior of the housing.

Granted: 2000-11-14
Abstract: A 2D image supplied from an image input unit including a wide view lens is sampled into a discrete form by an array sensor, and then mapped to a multi-resolution space by a 2D filter.  The feature of the supplied image is detected, and then the mapped image is transformed to a local pattern about the detected feature, and then the coordinates of the position of the feature and the code word of the local pattern are formed into a set which is then encoded.  The code is supplied to each cell of a stochastic automaton.  The quantity of visual information is calculated in accordance with the quantity of mutual information between different cells of the stochastic automaton consisting of cells in blocks, the coordinates of the position of the feature and the distance from the feature to the optical axis so as to control the optical axis of the image input unit in such a manner that the quantity of visual information is maximized.

Abstract: A method and device for calculating refractive index for a wafer of vitreous material.  A light beam is transmitted to a wafer at different angles of incidence, to produce fluctuations in the transmittance of the beam by the wafer.  The transmittance of the wafer is measured as the angle of incidence varies and the angular positions of transmittance maxima and minima are determined with respect to  a  maximum  or  minimum  corresponding  to  a  normal incidence.   The refractive index is obtained from these positions and from the number of maxima and minima in various angles of incidence.

Granted: 2008-01-08
Abstract: There is now provided storage stable polyol compositions and polyisocyanate based rigid closed cell foam made by reacting an organic isocyanate with polyol compositions in the presence of a blowing agent, where the polyol composition contains at least: a) an aromatic amine initiated polyoxyalkylene polyether polyol having an hydroxyl number of 200 meq polyol/g KOH or more; b) an aliphatic amine initiated polyoxyalkylene polyether polyol having an hydroxyl number of 200 meq polyol/g KOH or more; and the blowing agent is at least cyclopentane in an amount of 7 weight percent or more based on the weight of the polyol composition; and further, the cyclopentane blowing agent is soluble in the polyol composition, and the amount of the aliphatic amine initiated polyoxyalkylene polyether polyol is 10 weight percent or less based on the weight of the polyol composition. The polyol composition is adapted to solubilize cyclopentane in the polyol composition without sacrificing, and advantageously improving, the thermal insulation and dimensional stability of the resulting polyurethane foam. It was surprising to discover that less than 10 weight percent of the aliphatic amine initiated polyol was need to accomplish these objectives, and it was further surprising to discover that the aromatic amine initiated polyether polyol improved the thermal insulation of the foam.
