Abstract: A self-centering device for assuring that two plates that are rotatable with respect to one another will automatically align in one of two-stable positions. The device includes an O-ring entrained about two spaced posts located on the upper face of a bottom one of the plates and a roller depending from the bottom face of the upper one of the plates into a circumscribed space defined by the O-ring. When an external rotatable force is applied to the upper plate, an elastic force is applied to the roller such that when the external force is removed, the roller will move into one of the two stable positions.

Abstract: A Product Actuation Demonstration System (PADS) is powered from a product to which it is connected. The PADS includes a control module and an image storage module where the control module includes a local power generator which ensures that the power delivery capabilities of the product to be demonstrated are not exceeded while the power requirements of the control module and the image storage module are met.

Abstract: A liquid dispensing assembly including a stationary nozzle, a pump mechanism including a stationary, hollow dispensing tube attached at a first end to the nozzle and at its other end to a piston, a generally cylindrical operating body disposed about the piston and cooperating with the piston and the stationary dispensing tube and a housing containing and maintaining said stationary nozzle and said pump mechanism in relation to one another, wherein the pump mechanism is actuated by moving the cylindrical operating body toward the nozzle in order to dispense a unit dose.

Abstract: Rotating displays include rotation mechanisms which allow the displays to be easily rotated by consumers, yet automatically returned to one or more desired positions when released by the consumer. Holders for the display are affixed to turntables rotatably mounted upon a base wherein the turntables are attached to a biasing means capable of exerting a sufficient torque upon said turntable, relative to said base to cause an angular acceleration of said turntable toward a predetermined desired orientation. In preferred embodiments, the amplitude of the torque may be adjusted, depending upon the moment of inertia of the display, to cause a predetermined angular acceleration. The number and placement of equilibrium orientations may be selected based upon the desired geometric configuration of the display with which the rotation mechanism is to be used.
