Abstract: The invention creates a foldable wall structure for extending the interior space of transportable constructions, in particular a vehicle such as a camper van. The foldable wall structure has a first foldable wall which, in the folded-out state, forms a base wall of the wall structure, and a second foldable wall which, in the folded-out state, forms a cover wall of the wall structure. The foldable wall structure has a foldable fourth wall and a foldable fifth wall, which, in the folded-out state, form a first and a second side wall; the wall structure also has a frame structure, in which the wall structure has a third wall that can be translationally shifted relative to the folded-in first wall, the third wall forming an outer wall of the wall structure in the shifted state.

Abstract: A method for checking an installation location of a component in a failsafe automation system, wherein the components are connected to one another in series and uniquely defined addresses are continuously assigned from a first component to successor components, wherein, after the assignment of addresses to the components, a switching device is operated in the components such that a signal transit time measurement is performed incrementally with a test signal for each successor component, and wherein the test signal is emitted and re-received and the installation location of the successor component is check based on the time difference.

Abstract: A player insert for a gaming machine, the player insert comprising: an electronically controllable screen, a controller for said electronically controllable screen, an interface adapted to communicate between said controller and a host system associated with said player insert and with further player inserts, said controller being adapted to receive signals from a said host system via said interface and to thereby effect a display on said electronically controllable screen synchronized with at least one further display on at least one further player insert. The electronically controllable screen can be controlled to operate in a first state in which it is transparent and permits a separate display provided behind the screen to be viewed by the player and in a second state in which it is adapted to effect the display as stated above.
