A convertible seal for a suit used in and around water includes a body having at least one of a collar, a sleeve or a pant leg that must be sealed to prevent water entry during use. The collar, sleeve or pant leg is equipped with a permanently attached seal configuration that has an operative position is in axial alignment with the collar, sleeve or pant leg and a stored position out of axial alignment with the collar, sleeve or pant leg.

Thermal warming suits for a human occupant of a wet submersible vehicle are described. The thermal warming suits provide a dedicated envelope configured to encase at least a portion of the human occupant in a deformable suit that can be assembled around or donned, as well as be removed, by the occupant or others before or after entry and seating in or on the wet submersible vehicle, while underwater or surfaced. The suits provide a deformable, weight and space (i.e. volume) conscious, collapsible loose fitting perimeter around the occupant. The suits can be used to create a pneumatic barrier around at least a portion of the occupant by using a gas such as air provided from a gas reservoir to force water from the interior of the suit.

Generally, the present invention relates to an internal padding arrangement (100) for a diving helmet for reducing buoyancy of the diving helmet. Buoyancy of a diving helmet is typically compensated with ballast weights, which makes the helmet heavy outside of the water. In the present invention, buoyancy of the helmet is reduced with the internal padding arrangement comprising compartments (104) in padding parts (102), which compartments are inflatable with fluid.

A composite material (10) comprising: a base layer (48); a plurality of protective plates (41, 51, 51a, 51b) located on the base layer (48); an attaching means (43) to connect the base layer (48) to the protective plates (41), wherein
the attaching means (43) is positioned along a first direction (46) on the base layer (48) to resist pivoting of each protective plate (41, 51, 51a, 51b) about an axis normal to the base layer (48).

The present invention is directed towards a flexible conductive polymer for grafting to polymeric surfaces. The grafted polymeric devices expand and move with the space and/or diving suit fabric, hence, the devices on the suit fabric moves together. Supplying additional air in the closed loop system extends the utility of working in unique environments.

A segmented diving suit includes a base layer and a plurality of composite plates arranged on the base layer in a configuration designed to avoid joints or other anatomical features that bend. The composite plates include a spheres or microspheres dispersed/embedded in a carrier polymer. The spheres or microspheres provide one or more of thermal protection, sonic/blast resistance, and ballistic protection.
