  • Patent number: 9168370
    Abstract: A method and apparatus for the concurrent treatment of multiple oral diseases and defects while promoting general oral hygiene utilizing direct current electricity. Electrodes are used to deliver a direct current to the gingival tissues of a mouth in order to achieve a number of therapeutic, prophylactic, and regenerative benefits. These benefits include killing oral microbes, increasing oral vasodilation, reducing oral biofilm, improving oral blood circulation, reversing oral bone resorption, promoting oral osteogenesis, treating gum recession, and fostering gingival regeneration. Other benefits include the treatment of gingivitis, periodontitis, and oral malodor, and other systemic diseases correlated with oral pathogens.

  • Publication number: 20150219691
    Abstract: A transformer for monitoring current in a power cable is magnetically linked with the power cable connected to the electrical device, where the transformer produces a changing transformer signal in response to the presence of a changing current within the power cable. An input circuit located proximate to the transformer and having an output terminal and being electrically connected to the transformer so as to receive the changing transformer signal. The input circuit produces, in response to receiving the changing transformer signal, one of a first signal representative of the changing current, and a first circuit condition at the output terminal of the input circuit representative of the changing current in the power cable. The input circuit includes an impedance set having an effective impedance that comprises a plurality of elements, wherein at least one of the elements is not electrically connected to the remaining the plurality of elements.

  • Publication number: 20140259705
    Abstract: A pedal assembly for a velocipede is provided. The pedal assembly includes an axle, pedal body, a first drive pin and a first actuator. The axle includes a distal end and a proximal end. The axle defines a first cam groove. The proximal end is configured for releasable attachment to a crankshaft. The pedal body is rotatably coupled with the axle and is rotatable with respect to the axle about an axis. The axis resides in an imaginary plane. The first drive pin is movably coupled with the pedal and is movable between an inserted position and a withdrawn position. The first actuator is movably attached to the pedal body and is associated with the first drive pin. The first actuator is movable between a first position and a second position. An apparatus for determining a pedal configuration for a user is also provided.

  • Patent number: 8545451
    Abstract: A manually operable pump includes a fluid line operatively connected to a fluid source, and a manually operable actuator. A facilitator is used to facilitate flow of fluid from the fluid source through the fluid line. The facilitator is operably connected to the manually operable actuator. A piezoelectric system is operably connected to the manually operable actuator, and configured to capture energy from manual actuation of the manually operable actuator and regulate the speed of the facilitator.

  • Publication number: 20110099703
    Abstract: A toilet flusher for use with a toilet tank that has a fill valve and a bottom drain hole allowing water to flow out controlled by a toilet flush valve, the flusher being installable as the toilet flush valve and including: a longitudinally extendable siphon tube extending longitudinally from a drain hole fitting to a tube inlet with-in a float, such that, when sealingly attached to the tank drain hole by a drain hole fitting, the siphon tube will longitudinally extend upward as it is pulled up by the float floating on water in the tank. The flusher further includes: a float chamber around the tube inlet, the chamber being closed above a top edge of the tube inlet and open below it; floatation means that positions the floating float with the top edge of the tube inlet above the water and the chamber opening below the water.

  • Patent number: 7849664
    Abstract: A system (10) for dispensing dunnage material includes a chute (30) connectable to a supply (20, 40) of flowable dunnage. A container (12) or a bottom of the chute (30) is moved into a dispensing position where the bottom of the chute (30) is proximate the fill plane of the container (12). A controller (16) selectively opens a shutter (50) at the bottom of the chute (30) to dispense dunnage and then closes the shutter (50) to separate the dispensed dunnage from the dunnage in the chute (30) while also removing the dunnage above the fill plane of the container (12). The chute (30) includes at least one substantially horizontal plate member (54) that is openable to selectively vary the size of an aperture (52) created thereby at the bottom of the chute (30) for dispensing dunnage material therethrough.
