Abstract: In an illustrative embodiment, a two-piece folding tray table includes a personal electronic device (PED) support member connected to a tray section such that, in a stowed position, the PED support member is substantially flush with the tray table. The PED support member may be deployable in both a folded tray table configuration and a side-by-side tray table configuration to support a personal electronic device at a substantially identical angle regardless of tray table use mode.

Abstract: The “CARGO FIRE NET” looks much like a conventional net, the difference is that it was invented to extinguish fires in cargo settings. What makes this net different is the fact that it has several “suppression lines” inside, and throughout it, with (8) evenly spaced, exposed brass “#6540 suppression jet heads” connected to those lines, so as to spray “non-corrosive fire suppression agent” in the occurrence of fire. The “non-corrosive fire suppression agent” will be delivered by way of a centrifugal pump pulling from a 30 gal. holding tank, and into the net, so as to be sprayed. It can be used conventionally as a net, by draping it over the cargo, or non-conventional by suspending in a fixed state above the cargo. It's a net that extinguishes fires, just put it on the cargo, or hang it above the cargo, and connect it to “feed suppression line”, and walk away. When the “sensors” in the net detect an unacceptable temperature level, they will activate the system, thus starting the extinguishing process.
