Abstract: A support mechanism for a support structure includes first and second chain assemblies, and support subcomponents coupled to the first chain assembly. Links in the first chain assembly have a first protrusion structure extending in an inward direction. Links in the second chain assembly have a second protrusion structure extending in an inward direction. The protrusion structures are configured to releasably couple together in response to concerted movement of the chain assemblies along a predefined deployment path, and are configured to separate and decouple from each other in response to concerted movement of the chain assemblies along a predefined stowage path. The support subcomponents cooperate to form a deployable support surface, and the protrusion structures interlock to be self-supporting when deployed such that the deployable support surface is load-bearing.

Abstract: A morphable support mechanism for a load-bearing support structure includes a first chain assembly, a second chain assembly, and working surface subcomponents coupled to the first chain assembly. Links in the first chain assembly have inward-facing structural features, and links in the second chain assembly have inward-facing structural features. The inward-facing structural features are configured to releasably couple together in response to concerted movement of the first and second chain assemblies along a predefined deployment path, and are configured to separate and decouple from each other in response to concerted movement of the first and second chain assemblies along a predefined stowage path. The working surface subcomponents cooperate to form a deployable working surface, and the inward-facing structural features interlock to be self-supporting when deployed such that the deployable working surface is load-bearing.

Abstract: The modular networking system supplies data and aircraft power to an inflight entertainment, communication or cabin management device within the aircraft. At least one universal module package for placement within the passenger cabin carries an Ethernet switch which has a processor programmed to support deterministic networking, such as according to AVB/TNS protocols. Devices within the cabin are attachable to ports on the Ethernet switch. A power converter circuit and power injector circuit within the module package supply power to devices attached ports on the Ethernet switch. A microcontroller-controlled circuit switch selectively admits or inhibits supply of power attached devices in response to the received control data from the avionics system.
