Abstract: The invention concerns a method for the removal of a part (41, 55) of a particle collecting device (40, 41, 42, 55), which part is loaded with at least highly flammable particles (51). The part (41, 55) is removed from a process gas cleaning device (100) of an additive manufacturing device (1) by means of the following steps. An inert gas (50, 250) which substantially encloses the particles (51) is provided. The part (41, 55) of the particle collecting device (40, 41, 42, 55), is removed from the process gas cleaning device (100), wherein the particles (51) remain enclosed in the inert gas (50, 250).

Abstract: A passivation device for passivating filter residues of a filter device arranged in a process gas circuit of an additive manufacturing apparatus includes a reaction unit having an inlet suitable for supplying an oxidant, a coupling unit adapted to be coupled to the filter device for introducing filter residues into the reaction unit, a discharge unit suitable for discharging passivated filter residues from the reaction unit, and an energy supply unit suitable for effecting a reaction between the filter residues and the oxidant in the reaction unit.

Abstract: A central gateway controller (100) for managing data which is transmitted via a vehicle electrical system of a vehicle is provided. The gateway controller includes at least one central communication server, ZKS, (110) including at least one central information store, ZIA, (120) for centrally storing data, which is transmitted via the vehicle electrical system, and at least one communication module (130, 132, 134, 136) for transmitting data between the ZIA and at least one bus system (160, 162, 164, 166) belonging to the vehicle electrical system. The gateway controller can store the data transmitted via the communication module in the ZIA in uniform data sets. The gateway controller is thus not just used to route messages between different (message) producers or generators and (message) consumers or loads in the vehicle electrical system but is also capable of storing the data to be exchanged in the ZIA in a uniform format.

Abstract: A vehicle has a bus system, which is formed as an Ethernet bus system and has at least one distributor device with multiple port connections, to which a bus participant is respectively connected, which, via the associated port connection during the operation of the bus system, transmits data to the distributor device and/or receives data from the distributor device. The at least one distributor device is designed to carry out a diagnosis with respect to at least one of the port connections during operation of the bus system and to provide diagnostic data with respect to the at least one port connection.
