  • Patent number: 9498051
    Abstract: A gingival stimulator having optionally-angled bundled bristles anchored in at least one row in a brush head, and a narrow working footprint of collective bristle free tip ends having a maximum width dimension of approximately four millimeters. If splayed and/or flared, bristles have a preferred maximum free tip end density of approximately twelve bristles-per-square-millimeter. When moved into contact with teeth, the free tip ends easily navigate around them, promptly advancing to interproximal areas. The brush head is agitated with one or two hands and a quick vibratory motion when the free tip ends are in perpendicular contact with interdental papilla. Thus, gingival tissue becomes stimulated by the bristle free tip ends, dislodging food particles and bringing increased blood flow to it, keeping the gingival tissue in good health while avoiding the placement of adverse damaging forces against adjacent tooth structure during gingival stimulation, and preserving teeth from abrasion and notching.

  • Patent number: 9452848
    Abstract: An apparatus for the cleaning of a turbine engine comprises a towable wash cart having a reservoir for cleaning fluid. The reservoir is connected through a pump system to a wash ring operatively mounted to the cart. The wash ring has a plurality of spray nozzles about its periphery arid positionably adjustable for directing an atomized spray of the cleaning fluid into an inlet of the engine. The cart and wash ring is aligned with the engine such that there is no physical contact between the wash ring and engine during the entirety of the cleaning process. While a preferred cleaning fluid is pure water, the reservoir may be segmented to carry a number of different cleaning solutions, which can be mixed in a manifold of the pump system as may be desired for a particular cleaning process. The reservoirs may be heated and insulated to maintain the cleaning solutions at an elevated temperature.

  • Patent number: 9433337
    Abstract: A device, comprising a float, basin, and basin cover, is removably attached to interior rungs of a dishwasher via clip-hooks, and stabilized with a tongue arm, design features of the clip-hooks, and the cooperating portions of the basin or cover. The float rises to a completed water cycle ‘clean’ position as basin fills with water. The basin may block view of the float when in a ‘dirty’ position. The float provides visual indication of a completed water cycle, and therefore ‘clean’ dishes, after rising as a result of water introduced into the basin via holes in the cover. Water that was introduced into the device automatically leaves the chamber via one, or more, discharge holes/openings in the basin, while the float remains in the ‘clean’ position because of one or more retainers; e.g., magnetic force from one or more magnets. Retainers can generated and communicate position status to a smartphone.

  • Patent number: 9427127
    Abstract: A mobile floor cleaning robot includes a body defining a forward drive direction, a drive system, a cleaning system, and a controller. The cleaning system includes a pad holder, a reservoir, a sprayer, and a cleaning system. The pad holder has a bottom surface for receiving a cleaning pad. The reservoir holds a volume of fluid, and the sprayer sprays the fluid forward the pad holder. The controller is in communication with the drive and cleaning systems. The controller executes a cleaning routine that includes driving in the forward direction a first distance to a first location, then driving in a reverse drive direction a second distance to a second location. From the second location, the robot sprays fluid in the forward drive direction but rearward the first location. The robot then drives in alternating forward and reverse drive directions while smearing the cleaning pad along the floor surface.
