20090143914 | SYSTEM FOR OPERATING MODES FOR AN ELECTRIC TOOTHBRUSH - Various operational mode arrangements of an electric toothbrush ( | 06-04-2009 |
20100141185 | SYSTEM AND METHOD FOR MAINTAINING PERFORMANCE OF BATTERY-OPERATED TOOTHBRUSHES - The system periodically measures the battery voltage of the toothbrush and the current in a stator portion of the motor for the appliance. The amplitude of movement of the toothbrush workpiece is determined from the measured stator current. A circuit/control program changes the duty cycle or pulse width of the drive signal from the motor if the battery voltage drops below a first threshold value and a circuit or control program changes the drive frequency of the appliance if the amplitude of the workpiece movement falls below a first threshold value. A circuit/control program terminates the operation of the toothbrush if the voltage drops below a second threshold value or if the amplitude drops below a second threshold value, both of which are less than the respective first thresholds. | 06-10-2010 |
20100167236 | NON-PRESSURIZED SYSTEM FORE CREATING LIQUID DROPLETS IN A DENTAL CLEANING APPLIANCE - The appliance ( | 07-01-2010 |

20110244418 | NON-PRESSURIZED SYSTEM FORE CREATING LIQUID DROPLETS IN A DENTAL CLEANING APPLIANCE - The appliance ( | 10-06-2011 |
20120270178 | GUIDANCE ASSEMBLY TIP FOR A LIQUID DROPLET SPRAY TEETH CLEAING APPLIANCE - The guidance assembly is used for precise cleaning of interproximal spaces of teeth. The guidance assembly includes a base portion ( | 10-25-2012 |
20120284937 | MECHANICALLY DRIVEN RESONANT DRIVE TRAIN FOR A POWER TOOTHBRUSH - The power toothbrush includes a driving assembly which in turn includes a DC motor ( | 11-15-2012 |
20120326370 | NODAL SPRING ASSEMBLY FOR AN ELECTRONIC TOOTHBRUSH - A nodal-mounted spring arrangement for an electronic toothbrush includes a V-shaped spring member secured at both ends so that it can operate in out-of-phase torsion mode along the axial dimension thereof. In one embodiment, the V-shaped spring member includes two extended end regions, which extend below a longitudinal edge of the middle portion of the V-spring. The free ends of the extended portions are joined by a flat cross-piece. This “closed end” region is present at both ends of the V-spring. | 12-27-2012 |
