A hinge assembly comprises first and second tape spring elements, wherein each of the spring elements is configured to connect a first element of a space structure to a second element of the space structure. Each of the first and the second tape spring elements is movable from a folded state into an unfolded state by releasing stored strain energy, to deploy the first and the second element of the space structure. The first tape spring element is connected to a first direct current source and configured to conduct direct current of a first polarity supplied to the first tape spring element from the first direct current source. The second tape spring element is connected to a second direct current source and configured to conduct direct current of a second polarity, opposite to the first polarity, supplied to the second tape spring element from the second direct current source.

An internal combustion engine includes an electromagnetic actuator for operating a gas exchange valve, this actuator being situated on a cylinder head. The actuator includes a switchable electromagnet which is situated between two armatures. The armatures are axially set apart on a common armature shaft. A cavity is configured in the cylinder head, in which the actuator armature on the cylinder head side is at least partially accommodated, and the electromagnet at least partially delimits the cavity on the actuator side. This results in a compact internal combustion engine.
