System And Method For Determining The Resonant Frequency And/Or Amplitude Of An Oscillating Appliance Such As A Power Toothbrush
View pageUS Patent:
6918300, Jul 19, 2005
Filed:
Jun 24, 2002
Appl. No.:
10/179709
Inventors:
Joseph W. Grez - Snoqualmie WA, US
Kurt E. Steinke - Bellevue WA, US
Kurt E. Steinke - Bellevue WA, US
Assignee:
Koninklijke Philips Electronics N.V. - Eindhoven
International Classification:
G01N029/06
US Classification:
73579, 73578, 73649
Abstract:
A system and corresponding method for determining the frequency and/or amplitude of an oscillating apparatus, which includes a driving assembly having a stator portion and an armature portion, and a driving signal circuit which supplies a driving signal to the stator portion. A control circuit interrupts the drive signal momentarily, for at least a quarter of a cycle, at periodic intervals, resulting in a signal being induced into the stator coil from continuing movement of the armature. A measurement/read circuit is connected to the stator coil for determining one or both of the frequency of the induced signal and the amplitude of the induced signal. The frequency or amplitude information is then compared against pre-established values and any differences are used to change the driving signal so as to provide maximum performance of the appliance.

A46B 13/00
US Classification:
310 50, 310 21, 310 17, 310 12, 310 47, 15 221
Abstract:
The apparatus for converting side-to-side to rotational motion for a workpiece includes a spring assembly with a movable base mounting element which is driven in a slightly arcuate reciprocal side-to-side motion and a fixed mounting element spaced apart from the base element and mounted in the appliance so that it does not rotate or move in operation of the apparatus. A spring member, such as two planar leaf springs positioned at an angle to each other, is mounted between the movable base element and the fixed mounting element. A drive shaft member extends from the movable base element through the fixed mounting element and beyond. A workpiece such as a brushhead is mounted on the distal end of the drive shaft. The spring member is configured so that it is substantially less resistant to twisting action than bending action, such that the side-to-side motion of the base element results in rotation of the workpiece. 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.

International Classification:
A61C 17/34
US Classification:
15 221, 15 222
Abstract:
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.

US Classification:
433 80, 433 88, 433 89, 15 221
Abstract:
The stem portion of a toothbrush body has a set of bristles on a bristle plate at one end thereof, the stem portion including a shell or stem body having a longitudinal opening therethrough. A core member is configured to fit within the stem body, having two opposed grooves in the exterior surface thereof along the length thereof. The stem body has two grooves in the interior surface thereof, such that the grooves in the core member and the grooves in the stem body can align to form separate fluid channels along the length of the stem portion. The stem portion receives fluid from a reservoir and delivers the fluid to the bristle plate, which includes exit openings for the fluid. The core member and the stem body also include fluid-tight connections therebetween, separating the two channels.
Surface Detection System For Use With A Droplet Spray Oral Cleaning Device

A61C 17/00
A61C 17/00
US Classification:
356 72, 356448, 433 80
Abstract:
The surface detection system includes a source of an optical interrogating signal () which accompanies a droplet spray in an oral cleaning device directed to an oral surface (). The interrogating optical signal is reflected from the oral surface which the spray impacts and detected (). A selected characteristic of the reflected signal, such as intensity, is indicative of the nature of the oral surface, such as either gum tissue or a tooth surface. The detected reflected signal is then processed to determine the nature of the oral reflecting surface. The processor () then provides a resulting output signal which can be used to either warn the user concerning the nature of the oral surface or to change the characteristics of the spray appropriately according to the surface ().

Power Toothbrush Using Acoustic Wave Action For Cleansing Of Teeth
View pageUS Patent:
8037566, Oct 18, 2011
Filed:
Apr 7, 2005
Appl. No.:
11/722975
Inventors:
Joseph W. Grez - North Bend WA, US
Assignee:
Koninklijke Philips Electronics N.V. - Eindhoven
International Classification:
A61C 17/20
A61C 17/22
A61C 17/22
US Classification:
15 221, 433118, 433119, 601142, 601 46
Abstract:
The toothbrush includes a handle portion and a brushhead assembly which comprises a head portion and a stem portion. The head portion includes a bellows-like acoustic action member for creating acoustic wave action as it moves in and out in response to an acoustic driving force. A drive system is located in the handle and includes an audio speaker-type assembly to create acoustic waves which are transmitted through a transmission line to the acoustic action member. The acoustic action member is driven toward and away from the teeth when the toothbrush is operatively positioned within the mouth. The action of the acoustic member is directly or indirectly coupled to the fluid in the mouth, producing a foam which couples shear forces between the acoustic action member and the teeth/gums to produce a desired cleaning/therapeutic effect.
