  • Automatic filling mechanism and method for a hand-held oral cleaning device
    Patent number: 10357345
    Abstract: An automatic filling mechanism for use in conjunction with a hand-held fluid droplet appliance (10) for dental cleaning, the automatic filling mechanism having a door (42) to a chamber (40) in the hand held fluid droplet appliance (10) for holding fluid, the door having a female liquid inlet port (44) and a female liquid and air exit interface (46) having a snorkel system (80) attached thereto that is inserted into the chamber (40) that is used to fill the chamber (40) with fluid (112) from a reservoir (110) on a docking and charging station (100) when the hand held fluid droplet appliance (10) is inserted into a cradle (160) on the docking and charging station (100).

  • SECONDARY FLUX PATH FOR MAGNETOSTRICTIVE CIRCUITS
    Publication number: 20150162524
    Abstract: An energy harvester generates electrical energy from mechanical energy using changing flux properties in primary and secondary flux paths. An apparatus includes at least two primary flux paths. The primary flux paths include at least one bias flux path configured to exhibit a change in a flux property in response to a change in an external load applied to the bias flux path. The secondary flux path is magnetically coupled to the primary flux paths. The secondary flux path is configured to experience alternating flux directions in response to the change in the flux property of the bias flux path. Electrical energy can be induced in a conductor as a result of the alternating flux direction in the secondary flux path.
