Abstract: Disclosed is a cleaning device for a washing apparatus arranged in a vehicle, comprising a housing with a chamber which is formed in the housing, is configured to be filled with cleaning fluid and is hydraulically connectable to at least one spray nozzle for the cleaning fluid, and with at least one heatable heating wire protruding at least in sections into the chamber. To obtain high functional reliability even at low temperatures and to permit particularly rapid and reliable deicing, a heat-conducting element is arranged in the chamber to enlarge a heat-transferring convection surface, said heat-conducting element absorbing the heat from the heating wire, and being at least partially, and preferably completely, surrounded by the cleaning fluid.

Abstract: In a washer nozzle for a windshield washer system of a motor vehicle with a heating element held in a duct, a sealing compound for holding the heating element and a sealing element are manufactured from different materials and spaced apart from one another. Consequently, the sealing element may be manufactured from a material having poor heat conduction and the sealing compound from a material having good heat conduction. The washer nozzle has an especially long service life.

Abstract: A computerized method is provided for designing a vent in a hearing aid housing shell based on an image of a patient's ear canal impression, and wherein a program is provided on a computer-readable medium. With the program, an image of a starter housing shell based on the image of the patient's ear canal impression is created which is longer than a final version of the housing shell to be created. A starter vent running from an inner canal end near the patient's ear drum to an outer end of the starter housing shell is placed inside the shell. Components are then placed substantially as deep as possible inside the starter shell but lying outside of the starter vent. Portions of the starter shell lying beyond where a faceplate is to be mounted are removed and the faceplate is mounted. The starter vent is then grown larger so that it fills substantially all space inside the shell without interfering with the components.

Abstract: A method for designing a prosthetic device includes acquiring a three-dimensional image of an anatomical surface. A rules script for automatically performing a plurality of image processing rules using a script interpreter is executed. For each particular rule of the plurality of rules, one or more anatomical features that are relevant to the particular rule using a surface shaping engine are determined, the one or more determined anatomical features are automatically segmented from the acquired three-dimensional image using a feature detector, and the particular image processing rule is performed on the acquired three-dimensional image based on the automatically segmented anatomical features using a CAD tool. A prosthetic device design is produced based on the three-dimensional image upon which the rules of the plurality of image processing rules have been performed.

Abstract: A method and appertaining system provide for automatically adding a wax guard to a hearing aid shell impression. The location of a canal, tip of the canal, and central line of the impression are automatically identified in a digital 3D representation of a hearing aid shell impression. A first wax guard plane is determined at a predefined flip distance from the canal tip along the central line, and a second wax guard plane is determined at a predefined canal tip offset distance from the canal tip along the central line. A size and position for a feature of the wax guard is calculated based on predefined parameters, and the wax guard is constructed utilizing the calculated side and position. The type of wax guard can be a bell bore design, an open design, a Philip design, or a flip design.

Abstract: A system and appertaining algorithm provide a cutting and shaping of the hearing aid shell using an Ellipsoidal Line Cut that increases the speed of detailing operations and enables a creation of more cosmetically appealing shells. A contour algorithm determines a projected contour on the bottom cut plane that corresponds in shape to a portion of the line cut plane contour, and a merger algorithm defines a line cut surface between the portion of the line cut plane contour and the projected contour. An elimination algorithm eliminates parts of the new hearing aid shell design that extend beyond boundaries defined by the original hearing aid shell design.

Abstract: Disclosed is a device for cleaning a window of a motor vehicle, comprising a cleaning nozzle (9) that is mounted in a nozzle holder (4) so as to be pivotable about a horizontal axis. The nozzle holder (4) is fastened in a fixed manner to a body sheet of the motor vehicle. A specific spraying range which is to be sprinkled with cleaning liquid can be adjusted on the window when the cleaning nozzle (9) is pivoted.

Abstract: In a heating facility (6) for a motor vehicle component to be heated, a heating element (12) is held within a receptacle (11) by a sealing compound (13). The receptacle (11) is manufactured from aluminum and can be introduced into a correspondingly formed heating well of the component. As a result, the heating facility (6) can be mounted in a very simple way and used for heating highly diverse components.
