Abstract: A device (1) is provided for determining at least one parameter of a medium which has a sensor device (2) and an electronic device (3). To provide such a device with a cooling system for at least a portion of its components, the sensor device (2) and/or the electronic device (3) are arranged at least partly in at least one inner space (4, 5) of a housing (6). A passage (7) borders the inner space (4, 5) and a cooling chamber (8) through which a cooling medium can flow is arranged in proximity of the passage (7).

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.

Abstract: A device for measuring the fluorescence of a medium having a radiation source, an emission-receiving element and an optical imaging element arranged on the sensor side of the optical imaging element, and a scattering-receiving element arranged on the sensor side of the optical imaging element and in which the radiation source, the imaging element and the emission-receiving element are aligned and configured relative to one another so that the medium present on the medium side of the imaging element can be illuminated by radiation from the radiation source, and the emission intensity of the medium radiation emitted by the medium based on fluorescence can be detected with the emission-receiving element. To provide a device for measuring the fluorescence of a medium which has an increased reliability in measuring the fluorescence, temperature compensation is performed relative to the temperature of the medium and/or at least one of the receiving elements.

Abstract: A cleaning section of an oral hygiene device is disclosed. The cleaning section includes a cleaning element carrier mounted for oscillatory rotation around a carrier rotation axis; a gear unit arranged for being coupled to a drive shaft of a handle of the oral hygiene device, which drive shaft defines a drive shaft rotation axis in an attached state, and the gear unit further having an actuation element for transferring motion from the drive shaft to the cleaning element carrier during operation. The carrier rotation axis is parallel to the drive shaft rotation axis and is disposed at a distance to the drive shaft rotation axis.

Abstract: An oral cleaning section is disclosed. The oral cleaning section includes a first carrier having a cleaning side on which at least a first cleaning element is mounted and a second side opposite to the cleaning side, a second carrier having a cleaning side on which at least a second cleaning element is mounted, at least one aperture being formed in the first carrier such that the aperture extends from the cleaning side to the second side, with the second cleaning element extending through the aperture. The second carrier is arranged underneath the first carrier such that the cleaning side of the second carrier is underneath the second side of the first carrier and laterally extends beyond the aperture in at least a first direction. The first carrier and the second carrier are arranged for relative movement to each other.

Abstract: An oral hygiene implement is provided. The oral hygiene implement includes a housing; a movably mounted functional element; a fixation element that is secured at the housing and that essentially locks the functional element at the housing; and an axle that is supported by the fixation element. The functional element is arranged for movement around the axle and the fixation element extends through a cut-out or recess provided in a carrier element of the functional element, such that pulling the functional element out of the housing along the longitudinal axle extension direction is inhibited.

Abstract: An oral care implement is disclosed. The oral care implement includes a head section including a carrier element that is mounted for driven movement; a base section including a transmission element; and an at least partly elastically deformable neck section arranged between the head section and the base section. The transmission element is coupled to the carrier element for driving the carrier element into an oscillatory movement with an oscillation amplitude peak value. Further, the neck section is arranged as a parallel spring arrangement that deforms when a load above a first threshold load value is applied at the head section along a use direction such that the angular relationship between the head section and the base section is preserved and the head section and the base section move relatively to each other resulting in a reduction of the oscillation amplitude peak value.

Abstract: A method of manufacturing a brush head is disclosed. The method includes the steps of providing a bristle carrier on which at least a bristle tuft including a plurality of bristles is mounted; providing a cover structure having at least an aperture; constraining the free ends of the plurality of bristles of the bristle tuft into a defined cross sectional geometry such that it fits within the cross sectional area of the aperture; moving the cover structure and the bristle carrier relative to each other until the constrained bristle tuft and the aperture are positioned in spatial alignment; and releasing the constraint while moving the cover structure into a destination position in which the bristle tuft extends through the aperture.

Abstract: A handle of an electrical appliance for personal use is disclosed. The handle includes an elongated housing for receiving functional components of the appliance; and a control unit or an electric power supply. The housing includes at least two tube-shaped housing parts connected to each other at end portions thereof. An annular sealing element is associated with the end portions to seal the interface between the housing parts. The end portions of the housing parts have substantially the same diameter such that end surfaces of the housing parts abut against each other or against the annular sealing element. A holding member extending over the interface between the housing parts and the sealing element is provided for holding the housing parts together.

Abstract: A brush section for use with an electric toothbrush includes a movable contact element holder and a fixed contact element holder. The movable contact element holder is driven to move relative to the fixed contact element holder by an electric drive in a handle section which is coupled to the movable contact element holder. The risk of oral mucosa being pinched by the movement is minimized by any one of several methods, such as for example reducing the width of the gap between the two holders, adding a cover member, reducing the movement of the movable contact element holder, and the like. In addition, a low profile brush section is provided.
