    Abstract: A system for automated inspection of article exteriors includes a plurality of video cameras (32). One or more of these video cameras (32) is black and white while at least one is color capable. A strobe light for illuminating a specimen (22) disposed in a specimen area (24) onto which all of the cameras (32) are focused. The strobe allows for each camera (32) to capture a still image of the specimen (22), The black and white cameras (32) capture images which allow determining whether the exterior layout is acceptable. The color camera or cameras (30) captures an image which allows determining whether the coloration of the specimen (22) is acceptable. Specimens (22) are selectively rejected on the basis of these acquired images. The system is particularly useful in inspection of beverage container (22) and their associated labelling.

    Abstract: An engineered video inspection system for high speed video inspection includes an array of light emitting diodes including light emitting diodes for use in time delay integration (TDI) inspection of web materials. The light emitting diodes of the array are selectively controllable to accomplish sequential illumination and carefully controllable imaging of a specified section of a continuously moving specimen or specimens. LEDs with different wavelength light output, or multi-wavelength light LEDs are utilized of rapid and reliable inspection of surfaces with varying color or contour or detect characteristics. The system also includes an array of optional backlighting elements to aid in illumination of semi-opaque specimens to accomplish inspection thereof.

    Abstract: A parcel detection system works in connection with a stream of parcels, such as might be encountered in connection with bulk mail sorting apparatii. A presence of multiple parcels traveling adjacent one to another is detected with a line scan charge coupled device. A transducer array is disposed perpendicularly to the stream flow. Specular illumination of edges of the parcels is completed to facilitate capturing an image in the CCD array. An analog signal, obtained from the array, includes information representative of a number of adjacent parcels. This information is processed to provide a signal representative of a number of parcels traveling adjacent to one another in the stream.

    Abstract: A parcel detection system (A) works in connection with a stream of parcels (B), such as might be encountered in connection with bulk mail sorting apparatus. A presence of multiple parcels traveling adjacent one another is detected with a line scan charge coupled device (34). A transducer array is disposed perpendicularly to the stream flow. Specular illumination of edges of the parcels is completed to facilitate capturing an image in the CCD array (34). An analog signal, obtained from the array, includes information representative of a number of adjacent parcels. This information is processed to provide a signal representative of a number of parcels traveling adjacent to one another in the stream.
