Abstract: An input apparatus for operating and/or controlling a technical device includes a plurality of sensor elements which can be arranged spatially distributed in the oral cavity of a user. An interface circuit is coupled to the sensor elements and is configured to detect a respective current tongue position and/or tongue movement by means of the sensor elements. The interface circuit generates one or more control signals depending on the respective current tongue position and/or tongue movement and transmits the one or more control signals to the technical device. Advantageously, the sensor elements each include a transponder which is configured to receive an interrogation signal from the interface circuit and, in response thereto, to transmit an individually coded response signal to the interface circuit.

Abstract: The invention relates to a method for determining an actual value and/or an actual value range of at least one state variable of a fluid in a fluid flow by means of at least one indicator particle (9) introduced into the fluid. In addition it is proposed that the at least one indicator particle (9) is designed and provided for an irreversible property change of an indicator property of the indicator particle (9) in the case of a certain indicator value of the at least one state variable in the fluid flow and/or as a clear function of the actual value when a certain period of time has elapsed after the indicator particle (9) has been introduced into the fluid, wherein the indicator particle (9) is detected at a detection point, the indicator property of the indicator particle (9) is evaluated and the actual value and/or the actual value range of the state variable is inferred from the indicator property upstream of the detection point. The invention also relates to a method for operating a fluid-guiding device (7), an indicator particle (9) and a device (7) for determining the actual value and/or actual value range of the at least one state variable.
