Abstract: A head projector comprises a protective skirt for use with a helmet for protecting parts of a wearer's head below the peripheral edge of the helmet, such as the temporal and occipital regions. The protective skirt comprises one or more layers of high tensile strength flexible material, such as an aramid material and a securing mechanism for enabling the skirt to be suspended from the helmet in the required position. The protective skirt may extend to a position below a person's head to cover and protect a person's neck region.

Abstract: A protective garment is provided and includes a jacket having various releasably mounted protective components. The jacket includes a protective collar of ballistic resistant fabric for protecting the neck of a wearer and has front and rear portions which are releasably connected together at opposed side portions of the collar so that the front and rear portions can fold down when not in use. A protective plate is releasably fastened to the front of the jacket and the fastening mechanism allows the plate to be held in a number of different vertical positions. The jacket also includes a rear pocket for housing a rear protective plate. The sleeves of the jacket include a sleeve extension which is slideably mounted to the main sleeve to vary its effective length.

Abstract: A cooling system for a vehicle comprises a compressor for compressing refrigerant, the compressor being adapted to be driven by a power source installed in the vehicle, a condenser for receiving compressed refrigerant from the compressor, an expansion device for expanding refrigerant from the condenser, and a liquid-to-liquid heat exchanger for receiving refrigerant from the expansion device and exchanging heat between the refrigerant and a liquid. The liquid may comprise a coolant, and a pump may be provided for pumping the coolant through the heat exchanger to a point of use such as a cooling garment to cool personnel on board the vehicle. Alternatively, the liquid may be a drinkable liquid which is pumped through the heat exchanger to a suitable dispensing system to provide an on-board supply of cool drinking liquid.

Abstract: The present invention is a system for managing heat stress by both controlling the core body temperature of an individual and facilitating hydration. The system provides cooling to an individual through means of a liquid coolant such as water which is circulated by a pump through a heat exchanger to a heat exchange garment. The liquid coolant passes through the heat exchange garment where it extracts heat, increasing in temperature as a result of heat removed from the individual wearing the garment. The liquid coolant is then returned to the heat exchanger where it is again cooled. The cycle is then repeated. A drinking outlet provides a means for hydrating the wearer.

Abstract: There is provided a new and useful fluid conduit coupling apparatus which allows quick connection and disconnection with substantially no introduction of ambient fluids or air into the process fluid. In one aspect of the invention there is provided a quick connect/disconnect coupling for a fluid conduit, the coupling comprising assemblies for attaching to the ends of a conduit to be connected and for subsequently mating together, each assembly comprising a normally closed channel; means for expelling fluid from between the assemblies when the assemblies are to be connected to each other; means for preventing fluid from entering the assemblies from outside when the assemblies are being connected; means for opening the normally closed channels, means operable by the connecting of the assemblies to each other; latch means for securing the assemblies together, the latch means disconnectable by means of a hand operated unlatching means or by the application of a predetermined tensile force.
