Leak analysis |
January 2, 2001 |
| A container with a flexible membrane sealed to a container end may be tested for leaks as the container moves along a conveyor. The conveyor carries the container through a first region in which a negative pressure differential is established between the first region and the interior of |

Detection of unpressurized moving containers |
October 22, 1996 |
| To detect an unpressurized moving container, a fluid such as air is directed at the moving container. Thereafter, a level of deflection of the moving container resulting from the directed fluid is detected. An unpressurized container is indicated when the detected level of deflection |

Detection of foaming contaminants in containers using image processing |
July 16, 1996 |
| To detect a foaming contaminant in a moving container, an image of the moving container and any contents thereof is produced. Thereafter, image processing techniques are used to determine levels of low and high frequency spatial variations in intensity in the image. The levels of low |

Spectral detection of contaminants in containers |
June 18, 1996 |
| To spectrally detect a contaminant in a moving container, a set of reference spectral information related to one or more containers having known contents is stored. Thereafter, radiant energy is directed at liquid near the bottom of the container so that the radiant energy is modified by |

Detection of turbid or foaming contaminants in containers |
April 23, 1996 |
| To detect a contaminant in a moving container, radiant energy is directed into the moving container. Thereafter, a level of radiant energy scattered by contents of the moving container is detected. The presence of a contaminant is indicated when the detected level of scattered radiant |
