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).
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
