The invention relates to a method for operating at least one ultrasonic sensor () of a driver assistance system () in a motor vehicle (), wherein an output sound signal (S) of the ultrasonic sensor () is modulated in accordance with a type of modulation and by means of this modulation, a specific codeword is impressed on the output sound signal (S). For at least two mutually different functionalities (to) of the driver assistance system (), different types of modulation are in each case used for the modulation of the output sound signal (S) and/or in each case different lengths of the codeword.

The invention proposes a process for the surface treatment of aluminum in order to produce an electrical contact, and a corresponding component part, wherein an oxide layer on the aluminum surface is removed, for example by etching, in a first step and, in a second step, before an oxide layer is re-formed, the surface is sealed wet-chemically with a conversion layer having metal ions of zirconium or titanium.

Process for the surface treatment of aluminium

The invention relates to an ultrasonic sensor () in particular a motor vehicle ultrasonic sensor, comprising a housing (), and a diaphragm () which is supported in or on a section () of the housing () and which has a diaphragm base () and a substantially cylindrical wall section () adjoining the diaphragm base (), at least one stabilizing and/or attenuating auxiliary element () being arranged on or in the wall section () of the diaphragm ().

Ultrasound sensor with membrane

Ultrasound sensor (), in particular motor vehicle ultrasound sensor, having a housing (), having a diaphragm () which is mounted in or on a section () of the housing (), and having a decoupling element () which extends at least partially between the diaphragm () and the housing section (), wherein the decoupling element () and the housing section () have latching means () by means of which the decoupling element () and the housing section () are connected to one another.

Ultrasound sensor, in particular, a motor vehicle ultrasound sensor

The invention relates to a sensor () 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 (), whereby the base thereof () 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 () 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.
