Abstract: A computer-implemented method for creating measurement data describing a railway network or a vehicle travelling on a track. Measurement values are detected by a sensor situated on the vehicle or on the track. A sensor processor in communication with the sensor requests a time value describing a time point and/or a position value describing a position and/or a measurement sample from a processor situated on the vehicle. The time value, the position value, and/or the measurement sample are transmitted from the processor to the sensor processor. The sensor processor assigns a measurement value to the time value, the position value, or the measurement sample, such that the time value, the position value, and/or the measurement sample describe a measurement time point or measurement position, and measurement data comprising the measurement value and the time value and/or the position value and/or the measurement sample are stored in a database.

Abstract: A sound post assembly for a musical instrument, comprising two or more mechanically movable parts that allow for a length adjustment of the sound post assembly and one or more electrical components. In an example embodiment, the electrical components are configured to electrically measure the force exerted by the sound post on the upper and lower walls of the instrument's sound box. In some embodiments, the electrical components may operate to mechanically change the length of the sound post assembly through an electrical actuator, such as a piezo-electric actuator or an electro-magnetic motor. Also disclosed are example safety mechanisms and methods of wiring and interfacing said sound post assembly with a control unit.
