Abstract: Systems and methods are directed to a device comprising a product status synchronization device. Examples of the product status synchronization device comprise a plurality of input ports and an encoder input, each of the input ports coupled to one of a plurality of registers and configured to receive a signal indicative of a status assigned to a product by one of a plurality of process stations, and to register the status assigned to the product into the one of the plurality of registers coupled to the input port, wherein one or more of the plurality of process stations are located at different distances from a predetermined location along a processing line and are configured to asynchronously process one or more products moving through the processing line.

Abstract: System and technique for inspecting a moving film by measuring the levels of light transmission through a thickness dimension of the film are described. The system includes a light source configured to provide light including a particular wavelength, or a particular range of wavelengths. The light from the light source is directed toward a first surface of the film, and an image capturing device is located adjacent to the light source on a second side of the film opposite the first surface, the image capturing device configured to measure the levels of light intensity exiting a second surface of the film. Measurements of the level of the light intensity passing through the film may be spatially synchronized to physical positions along the film to generated at least one roll map indicative of light transmission characteristics of the film over the imaged portions of the film.
