| 20100043157 | Electro-Polymer Motor - An electro-polymer motor comprising a fixed member and a first actuator having a first end fixedly connected to the fixed member and a second end is presented. The first actuator comprises a polymer positioned between two electrodes. The electrodes are in communication with a power supply. The motor also comprises a driven member comprising a first leg and a second leg such that the first leg and the second leg are separated by an axis. The driven member is fixedly connected to the second end of the first actuator. The motor also comprises a compressible member having a first end fixedly connected to the fixed member and a second end fixedly connected to the second leg of the driven member. The compressible member is spaced apart from the first actuator. The first actuator elongates after the power supply applies a voltage across the electrodes to move the driven member. | 02-25-2010 |
| 20110072603 | Toothbrush - A toothbrush having a brush section and a handle section that longitudinally extends between a first end distal to the brush section and a second end proximal to the brush section is provided. The handle section includes at least three longitudinally extending edges on the outer surface of the handle section defining at least three longitudinally extending surface areas that each span between two neighboring edges. The at least three edges each twist in the longitudinal direction by a total twist angle lying in the range of from about 80 degrees to about 100 degrees. | 03-31-2011 |
| 20110080122 | METHOD AND DEVICE FOR ADJUSTING THE FREQUENCY OF A DRIVE CURRENT OF AN ELECTRIC MOTOR - A small electric appliance is described which comprises an oscillation-capable mechanism ( | 04-07-2011 |
| 20110265818 | Electric Toothbrush - An electric toothbrush is disclosed. The electric toothbrush includes at least one switch element and a control unit. The at least one switch element is operable by a user to switch the toothbrush to an on/off state, and operable by a user during the time that the at least one switch element is in its on state to select a brushing mode from a set of at least a first brushing mode and a second brushing mode. The control unit is arranged to control the electric toothbrush such that when the at least one switch element is operated to select a particular brushing mode in the on state, the toothbrush will then operate in that particular selected brushing mode when the at least one switch element is thereafter switched to an off state and then subsequently switched back to an on state, provided that the toothbrush was in the off state for a time period less than a threshold period (T). | 11-03-2011 |
| 20120068634 | METHOD FOR OPERATING AN ELECTRIC APPLIANCE AND ELECTRIC APPLIANCE - An electrical appliance with a resonant motor for driving a vibratory component is provided that has a control unit for driving the resonant motor with a predetermined driving frequency and for measuring the motion-induced voltage of the resonant motor and for determining whether the measured voltage value coincides with a predetermined target voltage value or whether the measured voltage value has crossed over the predetermined target value. The control unit measures the motion-induced voltage at a predetermined time of measurement (t | 03-22-2012 |

| 20100277013 | Oscillatory System For A Motorized Drive Unit - An oscillatory system for a motorized drive unit for the generation of a rotary oscillatory movement is provided. The system includes a first oscillatory component and a second oscillatory component, the components capable of oscillating relative to one another around an axis of oscillation; and at least two elongate spring elements, each spring element having a first fastening point and a second fastening point spaced apart from one another. The spring elements are elastic in the direction of the rotary oscillatory movement. For each spring element the first fastening point is connected to the first oscillatory component and the second fastening point is connected to the second oscillatory component such that the spring elements intersect at the axis of oscillation, the axis of oscillation having an angle of intersection different from 0 degrees. | 11-04-2010 |
| 20110138562 | Oral Cleaning Section Of An Oral Cleaning Device And Oral Cleaning Device - An oral cleaning section for detachable connection with a handle section of an oral cleaning device is disclosed. The oral cleaning section has a connector structure for detachably attaching the oral cleaning section to the handle section. The connector structure has a first receptacle suitable for accommodating a first protrusion of the handle section in the attached state, the first receptacle having a first resilient element provided on a first circumferential side of the first receptacle arranged in a circumferential direction, the circumferential direction being defined with respect to the longitudinal extension axis of the oral cleaning section. The disclosure is also directed to an oral cleaning device that includes an oral cleaning section attached to a handle section. | 06-16-2011 |
| 20110247158 | Display Panel And Manufacturing A Translucent Carrier Element Of The Display Panel - A display panel including a translucent carrier element that has an inner side, an outer side, and a display area is provided. At least one display element is arranged within the display area, the display element being formed by geometric structures realized as protrusions and/or depressions on both of the inner side and the outer side of the translucent carrier element. The display panel can be used in an information display that in particular comprises at least a light emitting element for backlighting the display element. The information display can be used in an appliance such as an electric toothbrush, wherein the protrusions and/or depressions integrally formed with the translucent carrier element. | 10-13-2011 |
