Patent CA-2171586-A1 (CA)
Inventor: SHIGEMORI YOSHIHIRO
IPC: G01J3/46
Filed: 1996-03-12
Abstract: The colorimetric value at a specified temperature is determined by measuring thecolorimetric value of a colored material sample at an arbitrary temperature using a color meter such as a spectrophotometer, colorimeter, or densitometer, and by correcting the measured colorimetric value on the basis of the change in colorimetric value with temperature, which change in colorimetric value is computed from the difference in colorimetric values observed on a single colored material sample under at a minimum of two different temperatures. When a spectrophotometer is applied, the spectral reflectance or the spectral transmittance of the colored material sample is measured. On the other hand, spectral reflectance or spectral transmittance is measured in advance for a dye or pigment at a minimum of two different temperatures. The difference (.DELTA.K) of absorption coefficient (K), the difference (.DELTA.S) in the scattering coefficient (S), and the difference (.DELTA.D) in absorbance (D) at each wavelength are computed from the preliminarily observed spectral reflectance or spectral transmittance. The spectral transmittance or spectral reflectance observed at an arbitrary temperature is corrected to define the colorimetric value at a specified temperature using the obtained values of K, S, and D. The method allows the determination of the colorimetric value of a single or a mixed color at a high level of precision using a simple operation under arbitrary temperature conditions without generating observation differences caused by temperature change.

Patent CA-2196853-A1 (CA)
Inventor: CRIPPEN RANDALL M
IPC: H01H21/28
Filed: 1997-02-05
Abstract: A method and apparatus for actuating an electrical switch and providing a variable electrical resistance usable to sense displacement of a movable member. The apparatus includes a housing for receiving the electrical switch, a variable resistance element and an actuator with a body member and a transverse cylindrical sleeve. An electrically conductive wiper is coupled to the actuator and contacts the variable resistance element, which varies with pivotal movement of the actuator. The body member is pivotably supported by an aperture of the housing about an axis of the cylindrical sleeve and a spring member biases the actuator toward an initial position, wherein the actuator is pivotable against the bias of the spring to actuate the electrical switch and to provide the variable resistance by positioning the electrically conductive wiper along the variable resistance element. A guide surface within the housing guides the actuator and the electrically conductive wiper in fixed relation relative to the variable resistance element when the body member is pivoted within the housing. The cylindrical sleeve protrudes through an aperture of the housing and is coupled to the movable member by a collar with a set screw without having to calibrate the variable resistor or the switch actuation timing.

Title: Method and apparatus for controlling the spectral reflectance of a material
Inventor: NUYAN SEYHAN
IPC: G01J3/46
Filed: 1997-02-26
Abstract: A method and apparatus for controlling the color of an article such as a paper web includes performing a comparison between target and measured reflectance values in numerous wavelength bands spanning the visible spectrum. The comparison quantifies correspondingly numerous errors that are modified by a non-linear operation, such as squaring, and then added together. The resulting sum is minimized by individually adjusting the application of a number of colorants to the article. The number of wavelength bands is greater than the number of colorants. This avoids metameric effects which are common in conventional systems that rely on three color space coordinates such as Hunter Laboratories L, a, b: C.I.E. L*, a*, b*; chromaticity x, y, z; and tristimulus X, Y, Z. Colorant response simulators enable the effects of changes in application of colorants to be tested while the actual application of colorants to the article is unchanged.
