Abstract: A floating dock including a submersible platform including at least one buoyancy tank wherein the buoyancy tank has a plurality of compartments each of which has a permanently open vent through which water is freely flowable into and out of the compartment and an inlet which enables air to be expelled from the compartment into the atmosphere or enables compressed air to be supplied to the compartment via a non return valve which causes water within the tank to be forced out via the vent, thereby increasing the buoyancy of the tank. The vent does not have any valves associated with it and is permanently open to the sea. As a result the floating dry dock of the present invention may be lowered and raised faster than conventional dry docks which rely on valved vents to control entry and exit of water into and out of their buoyancy tanks.

Abstract: Sensor stack venting techniques are described. In one or more implementations, one or more vent structures are formed within layers of a pressure sensitive sensor stack for a device. Vent structures including channels, holes, slots, and so forth are designed to provide pathways for gas released by feature elements to escape. The pathways may be arranged to convey outgases through the layers to designated escape points in a controlled manner that prevents deformities typically caused by trapped gases. The escape points in some layers enable at least some other layers to be edge-sealed. Pathways may then be formed to convey gas from the edge-sealed layer(s) to an edge vented layer(s) having one or more escape points, such that feature elements in the edge-sealed layer(s) remain protected from contaminants.
