Abstract:
A smart clothing and backpack system enables a user to perform many actions. The smart clothing includes circuitry and/or is made of a conductive material enclosed in an insulation material. The smart clothing includes a set of sensors configured to detect body information. The smart clothing includes multiple electromagnets configured to adjust a size of the smart clothing. The electromagnets are configured to have an increased attraction to make the smart clothing tighter on the body of the user. The system includes a smart backpack to communicate with the smart clothing. The smart backpack includes a Radio Frequency IDentification (RFID) reader configured to detect RFID tags on or in items within the smart backpack. Many other features are able to be implemented with the smart clothing and backpack system. The smart clothing is able to include a wetsuit configured to communicate with a surfboard and/or a backpack.

Abstract:
A radiant heat barrier insulation system includes a first substrate with a first layer of aluminum thereon. The system also includes a second substrate with a second layer of aluminum thereon. The first substrate is positioned to oppose the second substrate such that a gap is defined between the first substrate and the second substrate. The gap is filled with a randomly-oriented nest of carbon nanotube fibers.
Abstract:
Eye-shield condensation prevention system for use in a ski goggle, dive mask, medical or testing face shield or the like, that prevents undesirable hot spots on the eye-shield and maintains constant heat, with the ability to compensate for variations in resistance encountered from one eye-shield region to another, and/or one eye-shield to another, comprising a power source, a pulse-width modulator, a microcomputer, a heating element, and a sensing circuit. The microcomputer uses the sensing circuit to sense voltage and determine a value of resistance of the heating element. The microcomputer then uses this value to adjust the duty cycle of the pulse-width modulator, and may employ a two-dimensional table in assisting calculation. Multiple pulse-width modulators may be employed that correspond to a plurality of eye-shield regions and a corresponding plurality of heating elements.
Abstract:
Power saving method providing a burst of power for defogging an eye-shield apparatus with a thin-film heater, comprising: activating the heater from an off power level to an on-demand mode or from a preliminary intermediate power level during an active-on mode to a max power level and continuing heating for a predetermined first period of time, automatically reducing power after the first period of time and sustaining the lesser power for a second predetermined period of time, after which program control automatically turns off the heater, or automatically reduces the heat back to the preliminary intermediate power level depending upon the initial state of the heater upon activating the burst of power, whether on or off. The method may be repeated as often as necessary from off level in the on-demand mode, or from within a continuous active-on mode.
Abstract:
In a diver heating system of the type in which a fluid being circulated inhe circulation passage of the diver's clothing is heated by the controlled combustion of a reducing metal in an oxygen atmosphere, a temperature control system in which a gas flow control valve controls the oxygen flow to the reaction to automatically maintain a preset temperature of the circulating fluid and a gas shut-off valve serves as a backup to quickly shut-off the oxygen flow if the temperature of the circulating fluid exceeds a preset value. In both the gas flow control valve and the gas shut-off valve, the heated water is fed through a heat exchanger where it is in thermal contact with a thermofluid so that heat is transferred between the two fluids. The change in volume of the thermofluid with temperature is coupled to a motion bellows which operates to control the flow of oxygen through an orifice.
Abstract:
A passive survival suit for enabling a diver in a confined bell to maintain body temperature for at least a minimum interval in the event of failure of external thermal sources uses a combination of thermal insulation and a coacting breathing gas regenerator and scrubber system. The thermal insulation comprises a combination of a hooded sleeveless vest and a body shell, each of which provide a long heat conduction path length and minimum internal heat convection currents. The regenerator and scrubber system are arranged such that thermal energy in expired breathing gases is stored with high efficiency and used to heat breathing gas during intake, while the carbon dioxide scrubbing reaction is carried out in an optimal warm, moist atmosphere and contributes heat to aid in maintaining the diver's temperature.
Abstract:
A heat exchange unit is carried on the back of a free swimming diver and includes small tanks of propane and oxygen and a mixing chamber into which the two gases are fed and mixed. The gaseous mixture is then fed through a burner nozzle and burned to heat the atmosphere in a heat exchange chamber. The chamber includes a first coil therethrough in which air from the main oxygen tank is circulated and heated on its way to the diver's mask. A second coil through the heat exchange chamber carries water or other heating fluid from the diver's suit which is heated and returned.
Abstract:
A heater system for warming the body of a diver while underwater, to be used in combination with and powered by an air supply tank is disclosed. In essence, the heater system functions by taking in controlled amounts of water from the ambient, heating this water and delivering it to the diver's suit.High-pressure air from the air supply is admitted into the heater system through a pressure regulator which reduces the air pressure and utilizes the energy thus provided to operate as a pneumatic motor and water-circulating pump. The reduced-pressure air controls a fuel pressure regulator, allowing fuel, such as propane, to enter the system from a fuel canister. The air and fuel of controlled volume are permitted to mix and flow together into a catalytic combustion chamber where combustion is initiated by a spark generator. The circulating water passes through a heat-exchanging chamber surrounding the combustion chamber, absorbs the heat produced by the combustion reaction and is further pumped to the diver's suit.
Abstract:
A submersible body warmer apparatus adapted to use on a diver's body and comprising a heat radiating casing body in which a self-contained fuel is combusted with air or oxygen from a source from within or without the casing body. The casing body includes a passage through which air thereby heated passes to an exhaust opening while heat is radiated from the casing body to warm a diver's body.
