Abstract

See full text

Detection of components (22-24) missing from sealed packages (16) is accomplished by combining a multiplicity of electrical outputs representing the mass in volumes of the package (16) and comparing the combined value with a standard value for packages (16) including all components (22-24). In the preferred form, the mass is represented by the absorption of x-rays, with the packages (16) being conveyed on a conveyor (18) between an x-ray radiator (12) generating a fan-shaped x-ray beam (14) and a line array (20) of individual detectors (20a, 20b, etc.). The detectors (20a, 20b, etc.) detect radiation after passing through the package (16) and provide a numerical electrical signal equal to the amount of radiation detected. If the sum of the multiplicity of numerical electrical signals is less than the standard value, the package (16) is rejected from the conveyor (18) by a rejection device (30).
