Abstract:
Methods and apparatus for measuring a thickness of a coating on an moving object are provided. Light is directed toward the object at a predetermined location on the object such that a portion of the light interacts with the object. A I D and/or 2D maximum intensities for at least one wavelength channel is captured that is produced by the portion of the light interacting with the object. A measured average intensity of the wavelength channel and/or intensities and their arithmetic derivatives of multi wavelength channel geometries is converted into I D (averaged) and/or 2D thickness values. Based on these values an acceptability of the coating is evaluated and thickness calculated.
Abstract:
The unpacked depth of a cargo container is automatically measured as the items are removed therefrom. Information regarding where the unpacked items are to be placed is automatically presented using an active display and determined as a function, at least in part, of the measured unpacked depth. By one approach the foregoing includes using received information that correlates particular items with corresponding packed locations within the cargo container.
Abstract:
A method and device for measuring dimensions of a feature on or near an object using a video inspection device. A reference surface is determined based on reference surface points on the surface of the object. One or more measurement cursors are placed on measurement pixels of an image of the object. Projected reference surface points associated with the measurement pixels on the reference surface are determined. The dimensions of the feature can be determined using the three-dimensional coordinates of at least one of the projected reference surface points.
Abstract:
A component, such as a cyclonic steam separator baseplate of a steam generator, includes a surface subject to degradation during operation of the system in which the component is disposed. A profile is acquired of the surface of the component using an optical surface profilometry system concurrent with an image of the surface. A condition, such as degradation of the component is classified based on the acquired profile and image of the surface of the component. Component conditions may be monitored over time, trended, and classified as requiring maintenance, repair, or replacement.
Abstract:
A method and device for analysing a leaf to provide data on leaf content and/or dimensions of said leaf. The device (100) comprises an optical scanner having a power source (1) power/scan button (2) and a scanning aperture (10). The device is adapted to pass over the leaf and capture an image of at least a part of the leaf. A suitable processor then processes the resultant image from the optical scanner (100) to produce data on leaf content and/or leaf dimensions. In one embodiment processor may apply a plurality of algorithms to provide data on leaf dimension, nutrient content and/or chlorophyll status of the leaf.
Abstract:
Aparato y método que Simula la orientación espacial de una estructura respecto del sol para estimar el área correspondiente de captación solar directa, en condiciones ideales, que comprende: una plataforma de rotación de forma circular, la cual es rotada automáticamente por un primer motor servo o paso a paso, en donde dicha plataforma de rotación tiene en su borde exterior un anillo graduado, y soporta una maqueta volumétrica; una estructura circular con forma de anillo, que tiene una viga horizontal, ubicada mas abajo de su diámetro, que sujeta a dicha plataforma de rotación con dos soportes de anillo; un arco graduado de longitud mayor que un semicirculo, unido perpendicularmente con la estructura circular con forma de anillo en su parte inferior, terminando en su parte superior; y un arco concéntrico, con el arco graduado, que en su extremo superior tiene una unidad captadora de imágenes dirigida hacia la maqueta volumétrica.
Abstract:
The invention relates to a method and a sensor device(100) that allow for the determination of geometrical properties like the position and/or area of at least one detection spot(153) on a contact surface(152), wherein said detection spot(153) has a height that is different from the height of the residual surface. The detection spot(153) may for example be a region coated with binding sites for target molecules. The localization of the detection spot(153) is achieved by illuminating the contact surface(152) with evanescent waves and by observing an output light beam(L2, L2') which is affected by an interaction between test particles(1), which cover the detection spot(153) and the contact surface(152), and said evanescent waves. The test particles may for example be magnetic particles(1) that are attracted to the contact surface(152) by magnetic forces, or they may be transported to the contact surface(152) by sedimentation. The location of the detection spot(153) may be determined at the end or at the beginning of an assay and be used during the evaluation of measurements.
