Abstract:
The present invention provides a method and an apparatus for measuring relief imaged printing plates. The method comprises providing a source of illumination and directing the light therefrom into an optical element whereat the light is subjected to total internal reflection by at least one face of the optical element which face is exposed to enable it to be brought substantially into contact with a relief imaged printing plate, whereby when a relief imaged printing plate is brought into contact with the face or faces of the optical element, the raised parts of the relief imaged printing plate that are closest into contact with the face(s) of the optical element locally disrupt or "frustrate" the total internal reflection of the light, a detector being provided to detect the reflected or back scattered light to obtain an electronic image of the relief image on the relief imaged plate, the electronic image then being fed to an electronic circuit for analysis to determine the ratio of imaged to non-imaged surface area.
Abstract:
A method and apparatus for measuring and controlling the size of drops of viscous material dispensed from a dispensing system. A dispensing apparatus in accordance with embodiments of the present invention includes a housing, a dispenser that dispenses a quantity of the viscous material, a measuring apparatus having a bottom plate to receive the viscous material, a top plate that is positioned over the bottom plate after the viscous material has been dispensed, and a compressing apparatus that compresses the material between the top and bottom plates. The dispensing apparatus further includes a viewing system that views the compressed material to determine the quantity of material dispensed by the dispenser. In one embodiment, the dispensing apparatus includes a controller that controls the quantity of viscous material dispensed based on the quantity of material determined by the viewing system.
Abstract:
A process and devices are disclosed for automatically determining in relation to a surface the cell density of a cellular structure (4) of a honeycombed body (1) with a plurality of channels (3) that open at one front side (2) of the honeycombed body (1), so that the cell structure (4) is visible at said front side (2). An image with a known or determinable scale of at least part of the cell structure (4) is recorded by an optical instrument (9), the image is processed and while it is processed the number of cells is determined by counting the cells (5) and the cell density is calculated by correlating the number of cells and a reference surface determined by means of the image scale. The cell density can thus be quickly and accurately determined, in particular by computer-assisted image processing, production errors can be quickly recognised and costs spared.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on a storage device, for electric grid asset detection are enclosed. An electric grid asset detection method includes: obtaining overhead imagery of a geographic region that includes electric grid wires; identifying the electric grid wires within the overhead imagery; and generating a polyline graph of the identified electric grid wires. The method includes replacing curves in polylines within the polyline graph with a series of fixed lines and endpoints; identifying, based on characteristics of the fixed lines and endpoints, a location of a utility pole that supports the electric grid wires; detecting an electric grid asset from street level imagery at the location of the utility pole; and generating a representation of the electric grid asset for use in a model of the electric grid.
