Abstract: A child resistant blister pack container and stacked blister packs includes a container with a bottom member, a top member, and a child resistant push and lift mechanism. The bottom and top members, once filled and assembled, cannot be separated. They work together with a locking mechanism to assure that a stack of blister packs are secured, and that, upon use of a peel away feature of a blister pack from the stack, the sealed medication of that pack is automatically opened (exposed) for use. A breakaway mechanism involving non-coincidental notches permits removal of the top and bottom members seperately and not as a closed pack. These important features prevent or discourage a user from removing multiple packages that might otherwise be unprotected (no longer child resistant) until used.

Abstract: A load control circuit having an overload circuit capable of protecting a switching element from overload conditions over a wide range of operating conditions. The overload circuit limits the maximum average power dissipation of the switching element in accordance with a comparison of an average voltage across the switching element over a half-cycle and a variable threshold. The variable threshold is determined based on an ON-state resistance of the switching element and the environment in which the switching elements are operating. The variable threshold accounts for the squared term (V2 or I2) in determining power dissipation and allows power to be determined based on average voltage.
