Abstract: A water quality monitoring system for detecting sublethal degradations in environmental quality. The system continuously or periodically monitors the movements of a plurality of living organisms which are exposed to water from one or more selected sources. A computer controls and coordinates the tasks performed by the system. A video camera is used to visually monitor the movements of the organisms. Sensors measure other selected characteristics of the organisms' environment, including the temperature of the water. The computer includes software, responsive to the measurements by the sensors, for deriving a set of prediction parameters corresponding to the statistical distribution of expected movement patterns of the organisms. Other software is used for analyzing the organisms' movements and for comparing the observed movements with the set of prediction parameters, and for initiating the generation of a warning message when the organisms' observed movements do not correspond to the prediction parameters.

Abstract: An automatic on-line computer-aided inspection system for a running web utilizing a transverse web scanning means, detection means incorporating feature extraction and processing circuitry for generating unique output signals corresponding to said web scanning characteristic of web features of inspection interest, means converting the output signals to digital data words input sequentially to a digital computer, said computer applying one or more algorithms to said words, thereby calibrating the values of said features of said words, comparing said calibrated feature values to at least one set of product-qualifying values held in memory, and means responsive to the computer classifying the web as acceptable or non-acceptable as regards areas of preselected marketable size in the web.

Abstract: A non-marking type method and apparatus for optimizing the recovery, at on-line speeds, of salvageable sheet product from a large width web, utilized in conjunction with a radiation scanning type inspection system.

Abstract: An electro-optical system for the repetitive repositioning of a cyclically moving beam of radiation to a preselected point in space, particularly as applied to electro-optical web inspection.

Abstract: An electro-optical inspection system for a binary patterned web which automatically determines registration and the quality of subjects of inspection by comparison with a master pattern stored in the memory of a computer and then passes or rejects individual subjects of inspection depending on the outcome of the comparison effected.

Abstract: An automatically calibrated flying spot web inspection system adapted to detect transverse (or roll mark) defects and discriminate these defects from other defect types. Electronic circuit means responsive to a beam of radiation in either the reflection mode or the transmission mode detect and discriminate these defects from the other types.
