Abstract: The present invention relates to a storage apparatus for mounting to a two-wheeler. In addition to a container and a lid, the storage apparatus includes a closure which is configured to selectively occupy one of three states in a closed position of the lid: a releasing state in which the closure releases the lid for movement to the open position; a securing state in which the closure secures the lid in the closed position; and a locking state in which the closure locks the lid in the closed position. An identification means is associated with the closure, and the closure is configured such that it may be brought from the securing state to the releasing state without using the associated identification means, but may only be brought from the locking state to the releasing state by using the associated identification means.

Abstract: A method for measuring an elevation angle and/or azimuth angle with an antenna array. Identical transmitted signals that are formed of successive linear-frequency-modulated ramps are transmitted through the transmitting antennas of the antenna array using time division multiplexing, wherein the time division multiplexing is achieved through alternating attenuation of the signals transmitted by the transmitting antennas. Echoes of the transmitted signals are received by the receiving antennas and are down-converted to a baseband and sampled. The down-converted and sampled echoes are transformed by an FFT into a 2D image domain. Phase differences are determined from the image data, and, in order to compensate for a systematic error present because of the lack of separation of the two transmitted signals, an error-compensated elevation angle and/or an error-compensated azimuth angle is determined by means of a compensation.
