Abstract: Described is a component for a fill level measuring device or for a pressure measuring device. The component may include a coating with a microsmooth surface so that the microsmooth surface remains essentially free of any deposits.

Abstract: Described is an input and output device for inputting or outputting data of an electronic equipment. The input and output device is designed for being detachably mounted to the electronic equipment in at least two different positions. The input and output device features a first contacting arrangement which, independent of the selected position in the mounted state of the input and output device on the electronic equipment, electrically comes in connection with a second contacting arrangement present on the electronic equipment. In one embodiment, orientation of the device may be varied, thereby enabling it to be coupled to a receiver by a bayonet connection and with a set of contacting arrangement engaging the second contacting arrangement in any orientation. Moreover, described are an operating and display module, as well as to a combination of an electronic equipment and an input and output device that can be detachably mounted thereto.

Abstract: Described is a method for automatically initiating an update of a parasitic echo storage device in a fill level meter operating according to a runtime method. In this method individual echoes of echo curves of different ages are allocated, according to their typical echo characteristics, to global echo groups so that subsequently, after examining the behaviour over time of the echoes of the respective global echo curves, it can be judged whether the echoes of the respective global echo curves are useful echoes or parasitic echoes. Starting from this classification, the parasitic echo storage device is then updated with the oldest echoes of the corresponding global echo groups. Apart from the method for updating a parasitic echo storage device described is also an evaluation device for implementing the method as well as to a computer program and a computer program product for carrying out the method.

Abstract: The present invention relates to a sensor unit (1) having a measured signal receiver (4), which registers a measured signal (9), an A/D converter (5) for digitizing the measured signal (9), a transceiver device (6) for wireless data communication to an environmental device (2), and a processor (7). The processor (7) is a control processor for activating the measured signal receiver, the A/D converter, and the transceiver device. The digitized measured signal (9) is transmitted directly via the transceiver device (6) to the environmental device (2), without the complex and performance-intensive and therefore costly analysis occurring in the sensor unit (1).

Abstract: Described is a method for data communication in a communication system. The system includes a plurality of communication participants, each participant having a subsystem responsible for communication. A communication participant acts as master of the communication system, the subsystem of the master being operated continuously. The other communication participants act as communication slaves in the communication system. The subsystems of the communication slaves are de-energized, when no communication takes place. Furthermore, a protocol for controlling a bidirectional communication is provided. Establishment of the communication results from a special initial packet, which is transmitted by a communication slave to a communication master. The initial packet is acknowledged by the master with a confirmation packet. This confirmation packet comprises information, whether subsequent communication is required.

Abstract: The invention relates to an input and output device (1) for inputting or outputting data of an electronic equipment (25), wherein the input and output device (1) is designed for being detachably mounted to the electronic equipment (25) in at least two different positions. The input and output device (1) features a first contacting means (19) which, independent of the selected position in the mounted state of the input and output device (1) on the electronic equipment (25), electrically comes in connection with a second contacting means (41) present on the electronic equipment (26). Moreover, the invention relates to an operating and display module, as well as to a combination of an electronic equipment and an input and output device that can be detachably mounted thereto.
