In an embodiment, a command is received that requests movement of ownership of a target device from an origin compute element to a destination compute element. Receiver type information is collected at a site of a method that dispatches messages to receiver objects. The unique codes may be variable-length one or two byte codes. Short filler telegrams can be sent during the phase. The sensor has a sensor actuator for engaging the sensor fiber to generate an intrusion signal upon detecting predetermined movement of the moveable member causing the intrusion signal to be transmitted along the sensor fiber to a processor whereby the intrusion and location of the intrusion may be determined by the processor. This switch comprises an elongated conductor, and next to this at least one other short conductor, and where a connection element for the spindle nut is equipped with an electric conductive element, for creating contact between the two conductors.
