Abstract: This application relates to electric toothbrushes and in particular to a brush section for an electric toothbrush. The brush section may include static contact elements and movable contact elements to perform a cleaning operation. A head portion of the brush section is resistant to fractures or other material damage which might result from impacts, such as for example caused by dropping the toothbrush. It is structured to transmit forces from the impact away from an interior region of the head portion, to pass through the side portions of the head portion.

The handle section includes a motor and a drive shaft having a longitudinal axis; a coupling section at an end of the handle section for coupling a cleaning section thereto; a light source for emitting excitation radiation having a wavelength greater than about 580 nm; an assembly for directing the excitation radiation to the dental region of the mouth; a light sensor for receiving fluorescence radiation having a wavelength greater than about 850 nm reflected from dental deposits; a logic component operable to analyze the fluorescence radiation received by the light sensor; and a controller including a light source activating device that is activated when a diagnostic cleaning section including a coding device is coupled to the coupling section.

Abstract: An inductive charger for charging a hand-held appliance is disclosed. The inductive charger includes a charger coil surrounding a magnetic core, the magnetic core forming at least a part of a charger projection, wherein the charger projection is surrounded by the charger coil which is adapted to be inserted, together with the charger projection of the magnetic core, into a charging recess of the hand-held appliance.

Abstract: The personal care appliance kit includes a display device; and a handle for an electric device. The display device includes a continuous front panel; a window area being a part of the front panel, which window area is transmissible with respect to an infrared signal radiation; a display area being a part of the front panel, which display area is less transmissible than the window area with respect to the infrared signal radiation; and a receiver unit placed on a backside of the window area and adapted for receiving the infrared signal radiation from a transmitter unit for emitting the infrared signal radiation of the handle for indicating a handle use status; wherein the front panel is a liquid crystal display panel having at least one polarization filter layer; and wherein the at least one polarization filter layer is provided with a cut-out in the window area.

Abstract: A head for an oral hygiene device is disclosed. The head includes a carrier; and at least one elastic cleaning element attached to the carrier. The carrier is structured such that it provides the cleaning element with a first bending property in a first direction and a second bending property in a second direction. The first bending property and the second bending property are different from each other; and the first direction and the second direction are different from each other.

Abstract: An oral care device is disclosed. The oral care device includes a housing being at least partly formed of an electrically isolating material; a capacitor having a first electrode and a second electrode, the first and second electrodes being electrically isolated by the electrically isolating material of the housing such that they are not exposed to an outside environment of the oral care device; and a processor unit being electrically connected to the first and second electrodes. The processor unit is arranged such that during operation of the oral care device it determines a capacitance (x) of the capacitor in order to determine whether the oral care device is within a user's oral cavity or not.

Abstract: A brush head section for an oral care device is provided. The brush section includes an insert being made from a first thermoplastic material by injection-molding, at least one oral cleaning element and a cleaning element carrier consisting of a second thermoplastic material or a second thermoplastic mixture. The insert and the at least one cleaning element are partially embedded into the cleaning element carrier by over-molding and the cleaning element carrier at least partly engages behind the insert. The hardness of the second thermoplastic material is less than the hardness of the first thermoplastic material.

Abstract: A brush section for use with an electric toothbrush includes a relatively large brush head portion having a generally rectangular shape, although oblong, elliptical and other such shapes having a length to width aspect ration greater than 1 may be employed. The brush head portion is secured to a shaft portion of the brush section that may be configured to couple to a handle section. The handle section may include an electric drive including drive shaft, and the drive shaft may couple to the brush head via a coupling member positioned within the shaft portion. The electric drive may impart a rotary, oscillating rotary-oscillating or other suitable drive motion to the drive shaft that is, in turn, imparted upon the brush head by virtue of the coupling member.

Abstract: The invention relates to an electric shaver comprising a housing (1) and a shaving head (2) which comprises at least one cutting system, and which is pivotably connected to the housing (1), and further comprises means for locking this pivoting motion at several predetermined positions, whereby the shaving head (2) comprises a multitude of notches (23). To improve the function on comfort of the shaver the housing (1) provides a switch element (6) which is connected to at least one engaging element (10) that is adapted for being coupled with at least one of the notches (23).

Abstract: 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.

Abstract: 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.
