Title: System for calibration of optical instrument on satellite with reference light source
Inventor: SHIMIZU YUKIHARU
IPC: G01M11/00
Filed: 1992-09-18
Abstract: ABSTRACT OF THE DISCLOSURE     A calibration system for periodically calibrating an optical instrument on board a satellite with reference light.  In the disclosed system, a calibration unit has two photodetectors one of which is positioned near the light source which radiates reference light and the other near the aperture from which the reference light emerges toward optics of the instrument. Therefore, it is possible to discriminate between contamination or degradation of the optical instrument and contamination of the calibration unit.  Two identical and independent calibration units are employed to provide redundancy and enhance the accuracy of calibration.
Patent CA-2079370-A1 (CA)
Inventor: LAI GENHONE
IPC: A63B49/08
Filed: 1992-09-29
Abstract: The invention herein relates to a handle for sports rackets which offers an improvement of the conventional eight-surface octagonal tapered grip of conventional tennis rackets which have the shortcoming of causing calluses (hardened and thickened skin and/or medullary sheath) where the grip corners impact the hypothenar eminence of the gripping palm.   The aforesaid improved tapered grip consists of the modification of the conventional octagonal grip shape comprised of opposed horizontal surfaces into a polyhedral diamond shape, thus converting the conventional octahedral grip into a shape with multiple facets and more planar surfaces which thus minimize the number of  corners  impacting  the gripping palm and, moreover, provides more comfort and a greater number of solid gripping positions.

Abstract: A cross groove variety of constant velocity universal joint includes an inner race having a plurality of grooves formed in an outer surface thereof and an outer race having a plurality of grooves formed in an inner surface thereof. For each pair of associated inner and outer race grooves, the inner race groove is inclined in one direction relative to the rotational axis of the joint, while the outer race groove is inclined in the opposite direction. A ball is disposed in each of the associated inner and outer race grooves for providing a driving connection between the inner and outer races. A cage is provided with openings for retaining the balls in the grooves. The cage openings are formed having angled side walls which open up toward the center of the joint. The angled side walls are effective to position the point of contact between the balls and the angled side walls away from a lower edge surface of the cage. Consequently, an inner bore radius of the cage can be increased to allow greater angular motion and axial movement of the joint. Also, the balls are pinched against the angled side walls during operation of the joint to prevent the cage from chattering.

Abstract: A method and apparatus for non-contact and rapid identification of wood species is provided. The method comprises irradiation of a substance with infra-red radiation which is intense enough to introduce microstructural modifications of the substance surface. Various wood species are identified by analyzing intensity of optical radiation which is scattered from the modified surface. The surface is irradiated with two (2) infra-red beams of different level of energy density. A wood sample is analyzed with optical beams the first optical scanning is done prior to the first infra-red irradiation; the second optical scanning is done after the first infra-red irradiation; the third optical scanning is done after the second infra-red irradiation. It has been determined experimentally, that various wood species can be identified by analyzing intensities of the optical beams scattered from the modified surface. The method allows for non-contact, rapid and in-line identification of various species of wood.

Patent CA-2095346-A1 (CA)
Title: Rechargeable lithiated thin film intercalation electrode battery
IPC: C23C14/08
Filed: 1991-11-08
Abstract: A thin film electrode (10) for a rechargeable (secondary) battery is prepared by electron beam deposition of LiMn2O4, Li-CoO2, or LiNiO2 on a smooth, amorphous substrate surface (14) and in situ annealing of the deposited lithium composition at a temperature below about 500 °C. The amorphous nature of the substrate surface prevents epitaxial growth or ordered orientation of the minute composition crystallites thus formed. The finely granular structure of the resulting electrode thin film (16) presents abundant surface area that enables a 4V battery to provide current densities in the range of 500 mic-roamps/cm2. The low annealing temperature enables formation of the electrode structure and subsequent battery assembly directly upon semiconductor devices and integrated circuitry.

Abstract: A novel spectral interpolation (500, 600) and efficient excitation codebook search method (700) developed for a Code-Ex-cited Linear Predictive (CELP) speech coder (100) is set forth.  The interpolation is performed on an impulse response of the spec-tral synthesis filter.  As the result of using this new set of interpolation parameters, the computations associated with an excitation codebook search in a CELP coder are considerably reduced.  Furthermore, a coder utilizing this new interpolation approach pro-vides noticeable improvement in speech quality coded at low bit-rates.
