| 20090000797 | Mounted Beam Brushhead For Transverse Drive Power Toothbrush - The resonator assembly for a power toothbrush includes an elongated solid rod made from stainless steel, having a back assembly which includes permanent magnets which interact with an electromagnet in a drive system in the handle of the toothbrush to produce a transverse motion of the rod. A mount member is connected to the rod at a selected point along its length, and is mounted to a toothbrush housing so that the rod resonates about the mount member at a selected frequency. | 01-01-2009 |
| 20090001196 | Nozzle for Droplet Jet System Used in Oral Care Appliances - The nozzle member ( | 01-01-2009 |
| 20090019651 | DISPOSABLE HEAD PORTION FOR A NODALLY MOUNTED ROTATING TOOTHBRUSH - A head portion of a nodally mounted rotating toothbrush is removable from a handle portion, which has a driving system therein. The head portion includes a spring assembly, having two spring sections, the spring assembly having a node point between the two ends and a nodal mount member at the node point which is connected to a cover member of the head portion. A driving assembly is arranged to drive the first spring section, the second section rotating in an opposing direction from the first spring section, the second spring section having a drive shaft extending therefrom, upon a free end of which a brushhead is mounted. When the head portion is removed from the handle, the spring assembly is removed therewith. | 01-22-2009 |

| 20090251687 | Surface Detection System For Use With A Droplet Spray Oral Cleaning Device - The surface detection system includes a source of an optical interrogating signal ( | 10-08-2009 |
| 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 |
