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.
