  • Diaphragm and process for producing a diaphragm for an ultrasonic transducer
    Patent number: 9311908
    Abstract: The invention relates to a diaphragm (1) for an ultrasonic transducer having a diaphragm body (2) which is made of metallic material and is provided on an outer surface region (5; 8) with a coating (10). In order to make it possible for the diaphragm surface to be provided with a particularly damage-resistant coating, the coating (10) has a transparent form such that the surface region (5; 8) of the diaphragm body (2) is visible through the coating (10).
    Type: Grant

  • Sensor for a short-range detection system and/or parking system of a motor vehicle and method for the production thereof
    Patent number: 7551520
    Abstract: The invention relates to a sensor (12) for a short-range detection system and/or parking system of a motor vehicle, especially an ultrasound sensor. The sensor comprises a pot-shaped housing (10), whereby the base thereof (14) is embodied as an oscillating membrane. The housing comprises a coating on at least the outer side. The invention is characterized in that the coating is made of powder (18) which is weather-proof, which can be coated and which has no or no significant negative influence upon the oscillation behavior of the membrane. The invention also relates to a method for the production of this type of sensor.
