  • Patent number: 10051999
    Abstract: An apparatus and method for breaking eggs and separating egg liquids thus obtained. A first supply unit supplies a plurality of first rows of eggs to a second unit having a first endless conveyor and a plurality of corresponding second rows of egg breaker units. Eggs are transferred one by one from the first conveyor to a second conveyor which has a plurality of corresponding third rows of egg liquid containing cups with a part underneath the first conveyor for liquids transferred from the first conveyor to the second conveyor. A row of egg part receptacles are under the cups for collecting liquids. A cleaning section for the cups has a liquid washing head to clean and wash the cups and receptacles with a substantially downward cleaning flow.

  • Publication number: 20090251612
    Abstract: A programmable platform is provided that implements a video-processing algorithm that reduces halo artifacts. The algorithm corrects motion vectors of background motion in occlusion areas of a picture. The algorithm creates a re-timing vector from vector fields provided from a 3-frame motion estimator. The re-timing vector is produced by, first, selecting a number of candidate pairs of vectors from the different vector fields provided from the 3-frame motion estimator. Then, second, choosing one pair of candidate vectors based on an error metric. And, third, applying a linear or non-linear interpolation to obtain the required vector field. The re-timing vector provides a vector field for pixels between pictures n and n-\ such that halo about moving objects are minimized.

  • Publication number: 20050238761
    Abstract: In a method for coating at least the top of moving food products 100 with at least one layer of a free-flowing particulate coating material, coating material is poured from a storage container 60 over the moving food products. During the pouring, the coating material is partially segregated into coarse coating material 90 and relatively fine coating material, and substantially coarse coating material 90 is applied to the moving food products 100 first, followed by relatively fine coating material.
