A self-righting underwater escape and surface survival suit includes an ascent hood and an inflatable bladder in fluid communication with the ascent hood. Breathable air from the vessel is used to inflate the inflatable bladder for ascent to and/or survival on the water surface. During ascent, breathable air is provided to the ascent hood from the inflated inflatable bladder. The inflated inflatable bladder is configured to provide self-righting of the wearer upon surfacing and to support the wearer on the water surface, even if the wearer is incapacitated or the ascent hood is opened.

A cold weather survival suit includes a principal body cavity having pneumatically connected extensions to fit body extremities and a coverable cranial opening. The structure of the suit includes a layered structure of mechanically interconnected suits within suits. A composite of tear-proof and insulation material forms an internal suit or first envelope that is surrounded by a waterproof suit and then by a tear resistant suit.

A garment to repel underwater aquatic creatures. A first component for generating a control signal and a second component for receiving the control signal and transmitting an electromagnetic signal responsive thereto, an electromagnetic field created by the electromagnetic signal radiating from the second component into an aquatic area surrounding the garment. A water sensor disposed on the garment for activating the first and second components to transmit the electromagnet signal when the water sensor senses presence of water.

A waterproof garment is provided that includes a waterproof garment textile defining a garment opening, and a sealing sleeve joined at the garment opening. The sealing sleeve includes a substantially waterproof textile composite in the form of a tube extending between (i) a first end having a first opening and configured to fit tightly around a wearers body part and (ii) an opposing second end having a second opening and joined to the waterproof garment textile by a seam around the garment opening. The textile composite includes a stretchable textile with a substantially waterproof coating layer applied to the stretchable textile.

A survival helmet device for use in combination with a survival suit includes a helmet, inhale and exhale control valves, and at least one inflatable air cavity packet secured to the survival suit for selectively controlling the air supply and buoyancy of the survival helmet device and the survival suit.

A diving suit waterproof connector having a lighting device, includes: a fixing tube part watertightly connected to an end of each of sleeves of the diving suit; and a fastening tube part connected to a neck portion of an underwater work glove, wherein the fixing tube part includes fastening protrusions; a rubber ring press-fitted thereto; and a first contact terminal, and the fastening tube part includes coupling protrusions; a second contact terminal; and a lighting part electrically connected to the second contact terminal.

A system and method of measuring bioelectric signals generated by an individual, inclusive of humans or other living organisms, comprises a plurality of sensors, at least one of the plurality of sensors being constituted by a capacitive-type sensor. Sensor has an associated insulated layer of material preventing the conduction of direct current between an electrode and individual, wherein a bioelectric signal of individual can be measured underwater.
