A supply module for feeding electrical components to an automatic component-mounting machine has a locking element which is a piezoceramic bending transducer that extends in the longitudinal direction of the supply module along a supply path for the components. The basic idea of the present invention is to target the number of HARQ transmissions that is required to be able to decode the transmitted data successfully and to only transmit HARQ feedback information if the decoding result differs from an expected result, wherein the expected result is based on the targeted number of required HARQ transmissions. A 3D image generator generates a 3D panoramic image when the 3D panoramic space is viewed in a specified line of sight, with the shooting location of the panoramic image to be displayed being set as a viewpoint position. Bit lines are connected together at a common end, and word lines are connected together at a common end. The first water heater and the second water heater are in thermal connection with each other.
