| 20100237720 | OSCILLATORY MOTORS AND DEVICES INCORPORATING THEM - An oscillatory device incorporating a limited angle torque motor capable of oscillating one or more end effector(s) is provided. The device may additionally incorporate an ultrasound transducer and/or a waveguide structure. | 09-23-2010 |
| 20080209650 | Oral hygiene devices - Oral hygiene devices employing an ultrasound transducer are disclosed. The device is user-activatable to commence an operating cycle, and has a controller that may provide a timing function and may provide a variable level of ultrasound transducer output during an operating cycle. The controller may provide a monitoring function that is capable of detecting an ultrasound transducer fault condition and alert a user, through a user interface, when an ultrasound transducer fault condition is detected. The controller may be programmed to count the number of device operating cycles or accumulate the total device operating time and activate a transducer replacement signal following a predetermined number of uses or a predetermined accumulated operating time. The ultrasound transducer assembly may be provided in operative communication with an ultrasound drive circuit and power supply by means of a transformer assembly that inductively couples and transfers power from the ultrasound drive circuit to the ultrasound transducer. | 09-04-2008 |
