摘要:
Apparatus for inspecting sheet material having known characteristics is disclosed. The apparatus comprises means for providing a plurality of pixel signals each having a magnitude representing the intensity of electromagnetic radiation received from a corresponding point on the sheet material. The apparatus also comprises signal processing means for comparing the magnitude of each one of the pixel signals to a corresponding reference range defined by the known characteristics of the sheet material and generating a characteristic signal. The characteristic signal includes an event signal for each of the magnitudes falling outside of the corresponding reference range and a data signal for each of the magnitudes falling within the range, wherein the data signal represents the magnitude of the pixel signal. The signal processing means also generates an address signal representing the point on the sheet material at which the characteristic signal is generated. The apparatus also comprises system processing means for storing the event signals and the corresponding address signals to provide an indication of deviation from the known characteristics of the sheet material.

A light source module for use with a multi-camera array in a video surface inspection system includes a first light emitter which extends lengthwise across the entire width of a sheet to be inspected. Light from the first light emitter, which preferably comprises one or more fluorescent lamps, is received by a light guide and carried by the guide to uniformly illuminate a band extending entirely across the width of the moving sheet. The light guide comprises a transparent thermoplastic such that the light receiving end of the guide can be bent to define a plurality of sections which can be axially aligned with a corresponding plurality of fluorescent lamps. The fluorescent lamps may be powered by individual inverter ballasts which may be driven inturn by one or more variable dc power supplied to control the intensity of light emitted by the lamps. The light source module can also assist the inspection system in overcoming redundant data processing problems by providing second light emitters which illuminate the sheet in overlapping portions of the field of view of adjacent cameras of the multi-camera array to define data dividing points. Accordingly, duplicated data generated by the video cameras can be divided among the cameras at the defined data dividing points such that duplicated data is only processed once by the video surface inspection system.
摘要:
Disclosed are sheet inspection apparatus and methods for rapid, repetitive measurement of a quality attribute in each of a plurality of measurement zones of a continuously-manufactured sheet of material, wherein measurement is based on the interaction of one or more radiation wavelength bands with one or more constituents of the sheet. Simultaneous resolution of measurement zones is provided in both scanning and non-scanning applications.
摘要:
For measuring a property such as caliper of a traveling sheet, a sensor body and a target body are located on opposite sides of the sheet and constrained (e.g., by gas bearings) along a sensor path intersecting the path of the sheet. Gas bearings maintain these bodies at, substantially constant distances from the opposite surfaces of the sheet while permitting them to move in response to the position and thickness of the sheet. An active sensor element aboard the sensor body and a passive sensor element aboard the target body interact through the sheet to produce aboard the sensor body a response dependent on the sheet property. Manifestations of this response, such as light beam modulations, are produced, without solid bodily connections, at a location spaced from the sensor body where the manifestations are detected to produce a sheet property-indicative signal.

A method of non-invasively measuring the presence, absence, or concentration of one or more analytes in a tissue of a subject includes exposing at least a portion of a tissue of the subject to electromagnetic radiation; obtaining electromagnetic radiation measurement data of electromagnetic radiation from the tissue; using a mathematical transformation to filter or smooth the electromagnetic radiation measurement data; and determining the presence, absence, or concentration of one or more analytes by determining a radiation signature of the filtered or smoothed electromagnetic radiation measurement data; correlating the radiation signature of the filtered or smoothed electromagnetic radiation measurement data with the presence, absence, or concentration of one or more analytes to determine the presence, absence, or concentration of one or more analytes in the subject.
摘要:
In one aspect, a grate segment for a burner, comprises a substantially rigid body (30) having a dispersed array of cavities (38) filled with a refractory material. In another aspect, a solid fuel gasifier includes a housing (12) defining a gasifier chamber (14), and a solid fuel inlet (21), grate structure (22, 24) in the gasifier chamber. The grate structure includes base means, a plurality of agitator segments (32) positioned relative to the base means for reciprocating movement to agitate a fuel load in the gasifier, and means to support the base means and the agitator segments so that the latter reciprocate in a direction at a substantial inclination to both horizontal and vertical. In use of the gasifier a deep burden of fuel accumulates on the grate structure and the outward stroke of the reciprocation of the agitator elements is in the overall direction of flow of the fuel burden or generally oppositely thereto.
