Abstract: A system is provided for the detection of deposits in a fluid line that includes, but is not limited to a measuring body, and ultrasonic transducer and an ultrasonic receiver and at least one evaluation unit connected to the ultrasonic transducer and the ultrasonic receiver. The ultrasonic transducer transmits an ultrasonic signal and the ultrasonic receiver receives response signals generated by reflections in the fluid line. From known geometric changes in shape of the fluid line, resulting response signals are finally filtered out of the response signal sequence and from the remaining response signals relating to the deposits, the distances can be calculated between the ultrasonic transducer and the deposits.

Abstract: A method for collecting defect data of parts in a passenger cabin of a vehicle includes, but is not limited to connecting an electronics device allocated to a user to a central communication device, retrieving a user interface provided by the communication device by the electronics device, dialog-based inquiring of defect data of parts by the communication device by way of the user interface on the electronics device, and storing the requested defect data by the communication device in a central data storage unit. The electronics device can be mobile or permanently installed. Mobile electronics devices can be implemented by personal electronics devices of the passengers, which devices were brought into the passenger cabin.
