Abstract: A closing system for a door or hatch of a motor vehicle includes: a bearing piece and a cylinder lock situated on the bearing piece, the cylinder lock having a cylinder bushing and a cylinder core; and a locking clamp which is held on the bearing piece, engages the cylinder bushing from behind and has a holding lug which is oriented parallel to the cylinder bushing, a fastening screw passing through the holding lug, and the tip of the screw lying in a receiving depression in the cylinder bushing in order to preload the locking clamp against the cylinder bushing. A protective element rests on an outer side of the bearing piece and has at least one retaining lug which is oriented parallel to the cylinder bushing, and the fastening screw also passes through the retaining lug.

Abstract: A support system (1) for traffic support of ships (20a, 20b, 21a, 21b), having AIS ship reception units for receiving AIS radio signals containing ship traffic data, is characterized in that at least one flight object (2) is provided, comprising at least one AIS flight transmission unit (3), which is designed to transmit AIS radio signals containing ship traffic data inside an AIS transmission range (10) in such a manner that the transmitted AIS radio signals can be received by the ships (20a, 20b, 21a, 21b) located inside the AIS transmission range (10) by means of their respective AIS ship reception units.

Abstract: The invention relates to an AIS ship transceiver which, after reception of an AIS base station message, validates the transmitting AIS base station and activates or deactivates the emitting of AIS radio signals in dependence on the validation.

Abstract: The invention relates to a method for unambiguously identifying an object (1, 2, 3) having one or both of the following features a), b): a) at least one unambiguous identification means (4, 5, 6) is arranged on or in an object (1, 2, 3) that is in the form of a space projectile (1, 2); a transmission signal (11) having electromagnetic waves is sent from a transmission station (7) to the identification means (4, 5, 6) of the space projectile (1, 2) that is in space (15); an identification signal (12) having electromagnetic waves that are returned by the identification means (4, 5, 6) of the space projectile (1, 2) in response to the transmission signal (11) is received in a reception station (9); the space projectile (1, 2) is unambiguously identified using the identification signal (12); b) at least one unambiguous identification means (4, 5, 6) that is set up for directional reflection of an identification signal (12) in response to a transmission signal (11) with a defined reflection direction is arranged
