Abstract: Systems and methods for detecting that the animal has the allergy condition, determining a first quantity of a topical application medium and a first quantity of an allergen based at least in part on one or more attributes of the animal, providing a first topical application compound, the first topical application compound comprising the first quantity of the allergen and the first quantity of the topical application medium, and applying the first topical application compound to one or more ears of the animal one or more times to treat the allergy condition.

Abstract: A log-transporting conveyor chain is described. The conveyor chain incorporates log-transporting links with attached guide blocks which, in combination with an enclosing chain raceway, prevent undesirable play in the chain.

Abstract: A system that rotatively orients and skew positions a log for lumber processing. A log is placed in centering V's and rough centered. Rotatable scan spindles rotate the log while scanners obtain measurements at spaced locations along the log length and at selected rotative positions. Each angular position is analyzed for an optimum cutting pattern and the spindles are rotated to rotate the log into the most desirable angular position. The log is skew adjusted by the scan spindles and/or knee clamps in a carriage and conveyed to a saw array. A computer controls the cutting action to achieve the selected cutting pattern.
