20100058548 | TOOTHBRUSH BRUSHHEAD FOR A POWER TOOTHBRUSH WITH ANGLED BRISTLES - The brushhead, which has a rotating action, includes a bristle plate and three separate sets of bristle tufts. A first set of bristle tufts extends longitudinally down the approximate center of the brushhead and is arranged to extend vertically from the base plate. The second and third sets of bristle tufts are arranged on opposing sides of the first set of bristle tufts, with the second and third sets of bristle tufts being arranged at an angle outwardly, in opposing directions, from the first set of bristle tufts, the angle being in the range of 5°-45°. The length of all the bristle tufts is established so that the tips of the bristles in the first, second and third sets of bristle tufts form a shallow arc. | 03-11-2010 |

20100216090 | LIQUID DROPLET SPRAY CLEANING SYSTEM FOR TEETH WITH TEMPERATURE AND FILTER CONTROLS - The droplet spray teeth cleaning system includes in one aspect a window of temperature and volumetric flow ratio between air and gas for safe and comfortable yet effective operation, the volumetric flow ratio ranging between approximately 24 and 875 and the temperature from approximately 27° C. to a maximum of 60° C. The temperature is maintained by a flow-through heater ( | 08-26-2010 |
20100304327 | INTERPROXIMAL TEETH CLEANING APPARATUS WITH AN AIR-DRIVEN SPRAY - Interproximal cleaning is produced by a combination of fluid droplets producing a certain impact shear stress on the interproximal biofilm combined with shear stress created by the effect of air driving a liquid film ( | 12-02-2010 |
20100310301 | POWER TOOTHBRUSH USING A SHEAR THICKENING FLUID - The combination of a power toothbrush and an oral fluid, in which the oral fluid has the characteristic of changing viscosity, depending upon the action of a workpiece element portion, such as a flexible membrane, of the power toothbrush. The power toothbrush has two operating conditions. In one condition, the membrane moves toward and away from the teeth at a speed such that the fluid is liquid and flows easily to and around the teeth, including the interproximal regions. In the second condition, the membrane is moved at a significantly higher speed, in response to which the viscosity of the fluid increases substantially, having a shear rate at least as great as necessary to remove biofilm from the teeth. | 12-09-2010 |

20120064783 | Lightweight Outboard Electric Motor System - An outboard electric motor kit that includes an electric motor assembly with a unitized propeller hub, a transom mount, a rechargeable electric battery, and an optional recharger. The assembly includes an electric motor unit located in an upper housing. A lower tube stem is attached and that extends downward from the upper housing to a lower housing. Formed on the lower housing is a receiving cavity with a rearward facing propeller hub opening. A drive shaft coupled to the motor unit extends downward inside the lower tube stem and mounted to a gear support block located in the receiving cavity. Mounted on the end of the drive shaft is a main gear. Mounted on the gear support block is a fixed axle that extends coaxially aligned through the propeller hub opening. Extended through the opening and coaxially mounted over the fixed axle is a removable propeller hub assembly. | 03-15-2012 |

20130000093 | APPARATUS FOR CONVERTING SIDE-TO-SIDE DRIVING MOTION TO ROTATIONAL MOTION WITH A SPRING ASSEMBLY AND SYSTEM FOR TUNING THE SPRING ASSEMBLY - A method for tuning resonant spring assembly systems used in appliances such as power toothbrushes, particularly leaf spring systems, includes the step of measuring the frequency-dependent amplitude of the appliance workpiece, and then removing a portion of the spring member so as to decrease its spring rate sufficiently that the resonant frequency of the spring member closely approximates the drive frequency of the appliance. | 01-03-2013 |
20140008512 | Electric Outboard Motor Transom Clamping System - An electric outboard motor transom clamping system with two spaced apart side plates pivotally connected by at least one main pivot bolt or pin. Each side plate includes a clamp configured to press against the transom and hold the side plate in a rearward extending fixed position. Each slide plate also includes a ratchet slot located below the main bolt and a plurality of downward oriented pin slots transversely aligned the pins slots on the opposite side plate. Each pin slot is angled upward and rearward between 5 and 25 degrees from the center axis to a line that extends from the bottom of each pin slot to the main pivot bolt. A block member with two longitudinally aligned pins extend into the two ratchet slots. The pins engage the pin slots on the two side plates and hold the block member in fixed position between the two side plates. | 01-09-2014 |
