  • Patent number: 6608033
    Abstract: Coccidiosis in a bovine animal is prevented by administration of an effective amount of a macrolide antibiotic.
    Type: Grant
    Filed: August 1, 2000

  • Patent number: 6601974
    Abstract: An illumination obscurement device for controlling the obscurement of illumination from a light source which is optimized for use with a rectangular, arrayed, selective reflection device. In a preferred embodiment, a rotatable shutter with three positions is placed between a light source and a DMD. The first position of the shutter is a mask, preferably an out of focus circle. This out of focus circle creates a circular mask and changes any unwanted dim reflection to a circular shape. The second position of the shutter is completely open, allowing substantially all the light to pass. The third position of the shutter is completely closed, blocking substantially all the light from passing. By controlling the penumbra illumination surrounding the desired illumination, DMDs can be used in illumination devices without creating undesirable rectangular penumbras.

  • Patent number: 6506785
    Abstract: Treating or preventing the early stages of degeneration of articular cartilage or subchondral bone in the affected joint of a mammal is accomplished by administering a chondroprotective compound of Formula (I): where A is hydroxy, (C1-C4)alkoxy, amino, hydroxy-amino, mono-(C1-C2)alkylamino, di-(C1-C2)alkylamino; X and Y are independently H or (C1-C2)alkyl; and n is 1 or 2; R6 is halogen, (C1-C3)alkyl, trifluoromethyl, or nitro; R9 is H; (C1-C2)alkyl; phenyl or phenyl-(C1-C2)alkyl, where phenyl is optionally mono-substituted by fluoro or chloro; —C(═O)—R, where R is (C1-C2)alkyl or phenyl, optionally mono-substituted by fluoro or chloro; or —C(═O)—O—R′, where R1 is (C1-C2)alkyl. This treatment ameliorates, diminishes, actively treats, reverses or prevents any injury, damage or loss of articular cartilage or subchondral bone subsequent to said early stage of said degeneration.

  • Publication number: 20020131502
    Abstract: A method of video motion estimation is described for determining the dominant motion in a video image. The dominant motion is defined by a parametric transform, for example a similarity transform. In the preferred embodiment, selected pairs of blocks in one frame are traced by a block matching algorithm into a subsequent frame, and their change in position determined. From that information, an individual parameter estimate is determined. The process is repeated for many pairs of blocks, to create a large number of parameter estimates. These estimates are then sorted into an ordered list, the list is preferably differentiated, and the best global value for the parameter is determined from the differentiated list. One approach is to take the minimum value of the differentiated list, selected from the longest run of values which fall below a threshold value. Alternatively, the ordered list may be examined for flat areas, without explicit differentiation.
