Abstract: A battery fleet charging system for charging two or more battery packs simultaneously, at independently controlled charge rates. The present invention can intelligently distribute the available charge power among multiple batteries, either symmetrically or asymmetrically, as specified by a controller that specifies and regulates the charge voltage.

Abstract: The present disclosure relates generally to barrier assemblies, and more particularly, to the coupling of a barrier operator to the barrier that the operator is to move. In one embodiment, a barrier operator coupling includes a wedge member that is fixedly attached to an output shaft of the barrier operator. A housing is brought to bear against a wedge member, and an adjustment device is used to maintain the force between the wedge member and the housing.

Abstract: A multi-purpose implement is provided, including a racquet, having a handle portion and a flexible planar area held under tension by a frame, and a ball basket attached to the racquet and adapted to lift a ball directly from a generally horizontal surface. A method of using the implement, without contacting the ball with one's hands, includes holding the handle portion in one or both hands, maneuvering the ball basket into contact with a ball lying on a generally horizontal surface, lifting the ball directly from the generally horizontal surface with the ball basket, tossing the ball from the ball basket into the air, and while the ball is in the air, striking the ball with the racquet.

Abstract: An artificial nail having a three dimensional feature. The three dimensional feature may be a three dimensional representation of any known or imagined person, place or thing. The three dimensional feature may have a protrusion that is graspable. The protrusion may be used to assist in placing the artificial nail onto a fingernail or toenail. The artificial nail may include a tool or writing implement that may be extendible/retractable, movable and/or rotatable. The artificial nail may include removably attached three dimensional features. The three dimensional feature may include hair. The three dimensional feature may include a sound emitter or be designed to emit sound. The three dimensional feature may be plush or made from fabric. The artificial nail may include a power source and a light emitter to emit light from a portion of the three dimensional feature.

Abstract: A educational water toy designed for mounting on a vertical surface, such as a bathtub wall, is disclosed. It consists of a variety of interlocking parts which can be arranged in various sequences. The various parts are designed to conduct water; control, or respond to, water flow; or to attach other parts to the vertical surface. The fluid-conveying and -operated toy has a reservoir, at least one activity component, a fluid conduit which provides fluid communication between the reservoir and the activity component, with the activity component being placed into motion by fluid exiting from the conduit, coupling structures interconnect the components in fluid communication, and attaching devices for removably attaching the components to the vertical surface in an orientation such that the fluid flows along the fluid flow path under the force of gravity. The various activity components may include a paddle wheel, a turbine, an hourglass member, a dipper, a sprayer and a squirter.
