Abstract: A battery assembly includes a battery pack configured to supply energy to a load having a required energy, a housing enclosing the battery pack therein, a converter configured to convert an internal energy of the battery pack, and a controller configured to adjust a parameter of the converter based on information received from the load via a communication interface such that the converter converts the internal energy to the energy required by the load, wherein the converted internal energy is supplied to the load as the supplied energy.

Abstract: A pouring fitment and closure assembly comprising a central tubular body having at its interior most extremity an enlarged circular disk-like plate with a sharpened edge, the central tubular portion then opening up into a rib-formed plurality of ports to an interior plenum terminated at the outside end by an annular inwarldy protruding sharpened projection interior to the plenum forming a first sharp dripless and sealing edge. The central tubular body flairs outward in a skirt to join a flat annular radial sealing ring at its top which in turn terminates in a larger circular edge to form an acute angle, the second dripless edge.

Abstract: A child-resistant liquid seal closure and container combination featuring one or more camming projections on the container neck and one or more locking lugs on the interior surface of the closure which engage the camming projections to prevent rotational removal of the closure from the container. The closure may be removed from the container only by squeezing the closure on opposite sides to force the locking lugs radially outwardly beyond the camming projections to permit rotation of the closure relative to the container. The camming projections on the container neck are of sufficient axial height to prevent rotation of the closure relative to the container both when the closure is fully tightened onto the container and when the closure has been rotated 180.degree. relative to the container, thereby necessitating two separate squeezing actions to remove the closure from the container.
