Abstract: A method and an assembly for absorbing energy during an overload event. An energy absorber reduces loads on an object being transported on a loading unit during a single overload event, which introduces such a high degree of energy that there is an overwhelming likelihood the object would be damaged without an energy absorber. Measurement values on the current state of the loading unit are sensed. A control device determines an overload event and a damping of the energy absorber is set to a high value after the detection of the overload event. The damping is maintained for a specified prolonged time period and controlled dependent on the measurement values during the overload event to increase the load for objects during the specified time period initially to a specified threshold load and after the specified time dependent on the measurement values detected during the overload event.

Abstract: An energy absorber is controlled in an overload event to absorb potentially damaging energy. The energy absorber acts between a receiving unit for receiving objects for transporting and a carrier device that connects to a transporter. An absorber force can be influenced by an electrically controlled magnetic field unit. Measurement values of loads acting on the loading unit are captured sequentially and an overload event is determined if a measure derived from the measurement values exceeds a predetermined threshold value. After the onset of an overload event a prognosticated load curve of the loading unit is assessed from a multitude of measurement values captured from the onset of the overload event. A planned power flow curve for the magnetic field unit is determined and the load curve is damped time-dependent so that a planned load curve ensues which remains beneath a predetermined load limit.

Abstract: An energy absorber reduces an excessive load between an object and an assembly in an overload event. The energy absorber includes an absorber cylinder and a piston device with an absorber piston and a piston rod. A first chamber of an absorber chamber is filled with a field-sensitive absorber fluid. The piston has an absorber valve with an absorber duct extending in an axial direction and being subject to a selective field of a field generating device. A ratio of the outer diameter of the piston rod to an outer diameter of the absorber piston is greater than 0.6 and the first chamber extends in a space around the piston rod. During the relative motion of the fastener and the holding device the field-sensitive absorber fluid is urged through the damping duct of the absorber piston.

Abstract: A packet data network gateway, P-GW, is located in a second network for supporting user plane data to terminal devices in a wireless communications system that additionally comprises a first network having a first packet data network gateway, P-GW operably couplable to the P-GW. The P-GW comprises a processor arranged to: check a destination address of received packets from the first P-GW to determine whether the received packets are destined for any of the terminal devices, and in response thereto: extract one or more properties of said received packets if they are destined for any of the terminal devices served with user plane data; or discard said received packets if they are not destined for the terminal device(s).

Abstract: A payload mount adapter assembly for use with an aircraft is disclosed. The payload mount adapter assembly includes, but is not limited to an upper section that is configured for mounting to the aircraft and a lower section that is configured to receive a payload. The lower section is releasably engaged with the upper section such that the lower section is substantially unadjustable with respect to the upper section when the lower section is in a fixed state and the lower section is substantially adjustable with respect to the upper section when the lower section is in a released state.

Abstract: A machine gun assembly includes, but is not limited to, a receiver, a barrel extension, and an interlock element. The barrel extension is mounted to the receiver and moves between forward and retracted positions with respect to the receiver. The barrel extension is configured for quick-release engagement with a barrel. The interlock element is mounted to the receiver and moves between a blocking position and a clear position. The interlock element has a blocking portion positioned to obstruct movement of the barrel extension to the forward position while in the blocking position and the blocking portion is positioned to permit movement of the barrel extension to the forward position while in the clear position. The interlock element moves to the blocking position when the barrel disengages from the barrel extension and moves to the clear position when the barrel is correctly engaged with the barrel extension.
