Abstract: A netting apparatus especially useful for underwater use for the capture of crustaceans and other prey is capable of one-handed rapid net mouth closure. The apparatus includes an elongate handle coupled distally with a hoop and a flexible net mounted about the circumference of the hoop opening to form a net bunt. Access into and out of the net bunt is selectively restricted by a unique net closure mechanism associated with the handle, hoop and net. The net closure mechanism includes a pair of elastic bands disposed across the hoop opening with the net disposed between the bands to create the net mouth. A drawing apparatus is adapted to stretch the bands apart from one another from their normally relaxed substantially parallel orientation wherein the net mouth is said to be “closed” to its “open” position wherein the bands are held under tension.

Abstract: A panel sub-system for a life safety system having a plurality of inter-connected panels, each panel including a local rail, and a plurality of modules, each comprising a module circuit board, inter-connected by the local rail. The first of the modules have a central processing unit, and the remainder I/O modules having a variety of functions, as well as at least two channel members containing respective rail circuit boards defining each local rail. Moreover, each board has spaced electrical connectors for connecting to the respective module circuit boards.
