Abstract: The present disclosure is directed to a magnetic coupling system to improve stability at low magnetic docking forces, such as docking between a hand held device (102) and its base (104), where the hand held device and the base each contain a magnet (112, 108) with the same direction of polarity, arranged so that the two magnets attract each other when the hand held device is docked to the base. An auxiliary magnet (114) is included in the magnetic coupling system. In one example, the auxiliary magnet may be arranged within the hand held device at a predetermined distance from the other magnet within the hand held device and is arranged with polarity in the opposite directions as the other two magnets. In another example, the auxiliary magnet may be arranged within the base at a predetermined distance from the other magnet within the base and is arranged with polarity in the opposite direction as the other two magnets.

Abstract: This disclosure is directed to systems and methods for automatically resetting pause control on an oral irrigator. The methods use a resilient device which stores potential energy when the oral irrigator is turned on or the pause control feature is turned off. The stored potential energy is then released and switches the pause control feature on when the oral irrigator is turned off or placed on its stand. The pause control assembly includes a slider coupled to the valve, where the slider has a first protrusion; a return which makes contact with a first protrusion of the slider; and a stopper, which in the closed position prevents the return from moving. The automatic pause control reset can also include a pressure plate and a pressure chamber which respond to a change in fluid pressure to permit the opening of a pause control valve.
