Abstract: A cigarette filter rod system comprises a plug combiner machine having a knife located downstream from a sensor. The knife generates a trigger signal which prompts an Inspection Unit to locate a previously stored frame of sensor data corresponding the rod which was cut by the knife. The Inspection Unit applies thresholds to the frame of sensor data to determine the location of filter segment boundaries, and then determines whether air rings are present in the data. The Inspection Unit then compares measurements made on the frame of sensor data with a pre-stored recipe indicating expected values for the frame. Statistical data is sent to a Human-Machine Interface Unit for analysis and display. The system performs filter rod rejection and cut registration based on the analysis performed by the Inspection Unit and the Human-Machine Interface.

Abstract: An improved x-ray laser aiming system providing coaxial laser aiming in a configuration opposed to the x-ray emitter is disclosed. The present invention comprises two basic components: 1) a laser sight coupled to an x-ray emitter, and 2) a laser device assembly coupled to an x-ray collector. The laser sight provides a means for aligning the x-ray emitter with a laser beam during surgical or diagnostic procedures. The laser device assembly is removably coupled to the image intensifier or x-ray collector. The laser device assembly contains a point laser source and a fixed reflective surface or mirror for directing a laser beam coaxially with the center ray of the x-rays emitted by the x-ray emitter, but in the opposite direction. The laser source is, therefore, in a configuration opposed or opposite to the x-ray emitter.
