A centrifugal separator for cleaning gas containing contaminants includes a stationary casing enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas to be cleaned, a rotating member including a plurality of separation members arranged in said separation space and being arranged to rotate around an axis of rotation, a gas outlet configured to permit discharge of cleaned gas and including an outlet opening through a wall of the stationary casing, a drainage outlet configured to permit discharge of liquid impurities separated from the gas to be cleaned and an electrical motor for rotating the rotating member. The centrifugal separator further includes a control unit configured to control the operation of the electrical motor and to drive the electrical motor in at least two different operational modes and to further switch between operational modes depending at least on information of at least one measured internal parameter of the electrical motor.

An optical bus system () having a start-up state and at least one operating state is disclosed. The optical bus system () includes a mechanical support structure () arranged to receive and hold a master module () having a downstream optical interface () and a set of slave modules () each having an upstream optical interface () and a downstream optical interface (). The modules are attached to the mechanical support structure () such that optical interfaces of adjacent modules are aligned and in close proximity to each other in order to enable optical communication () between adjacent modules. Each slave module () is further provided with circuitry to form one or two shunting signal paths () depending on operating state after an addressing procedure is completed in the start-up state. Hereby, it is e.g. possible to realize a robust and cost-efficient optical bus system with high bandwidth capability.

An embodiment of the present invention discloses an apparatus for recyclable absorption of electric retardation energy from a multiple axis industrial robotics system, including a robot control unit and at least one drive unit, which generates the electrical retardation energy at retardation. By an apparatus according to the present invention, the electric retardation energy, which occurs when a drive unit is retarded and is transferred into generator mode, may be recycled by the brake unit of the apparatus, which accelerates a mechanical device connected to the brake unit. The electric retardation energy is thus transferred into kinetic energy that may be stored in mechanical devices. An embodiment of the present invention also refers to a corresponding method for recyclable absorption of electric retardation energy from a multiple axis industrial robotics system.
