摘要:
A system for an atmospheric suit includes one or more modular proximity sensors (150) affixed to corresponding one or more portions of the atmospheric suit. Each of the one or more proximity sensors (150) provides a distance to a nearest object from the corresponding portion of the atmospheric suit. The system also includes processing circuitry (140) to obtain the distance from each of the one or more proximity sensors (150) to the nearest object and to provide information to the wearer of the atmospheric suit.

A modular, multi-crew life support system (100) and a method of assembling the system involve a fan (120) to draw in ambient air. The system includes one or more assemblies (135) that produce conditioned air from the ambient air, and a housing (210) to support an oxygen source (150). The system also includes a port (155) configured as an inlet from the oxygen source to augment the conditioned air, and a duct (160) to disperse a result of augmenting the conditioned air as output air to support two or more occupants of an enclosure.

Disclosed is a Multi-Use Dust Mitigation System ("MDMS"). The MDMS includes a finger section, a hand section physically attached to the finger section, a fabric-material within both the finger section and hand section, a plurality of conductive-fibers within the fabric-material, and a plurality of input-nodes approximately adjacent to the fabric-material. The fabric-material includes a front-surface and a back-surface. The plurality of conductive-fibers are approximately parallel along the fabric-material and are approximately adjacent to the front-surface of the fabric-material. The plurality of input-nodes are in signal communication with the plurality of conductive-fibers and configured to receive an alternating-current ("AC") voltage-signal from an input-signal-source and the plurality of conductive-fibers are configured to generate an electric-field on the front-surface of the fabric-material in response to the plurality of input-nodes receiving the AC voltage-signal from the input-signal-source.

A thermal management system includes a space structure (22), a feed water container (24), a water feed line (26), a pump (28), and a filter device (30). The space structure includes a heat source (34) connected with a fluid loop (36) for conveying a working fluid through the heat source to regulate temperature and a sublimator (38) connected with the fluid loop to receive the working fluid. The sublimator has a porous surface (40). The water feed line is connected with the container and the sublimator. The pump is located in the feed water line and is operable to move the feed water from the container to the sublimator. The sublimator is operable to cool the working fluid using the porous surface. The filter device is located in the water feed line between the pump and the feed water container. The filter device includes an adsorbent bed (44) to remove organic compounds.

An extravehicular activity system includes a vehicle, 10, having a bulkhead providing a port. The bulkhead separates an interior environment and an unenclosed exterior environment. The exterior environment is configured to be exposed to atmospheric pressure in a donning condition. A cover, 22, has a perimeter with a side of the perimeter secured to the bulkhead by a hinged joint. A spacesuit, 12, is supported on the bulkhead in the exterior environment and includes a flange, 32, providing a rear entry opening aligned with the port. A PLSS, 18, is retained in the cover, 22, and spaced from the flange, 32, in the donning condition. The PLSS is configured to be rotated about the hinged joint, 36, and into engagement with the flange, 32, in a donned condition in which the PLSS, 18, is removably secured to the flange, 32.
摘要:
Ballistic collar comprising a bellows shaped member (1) which is arranged to surround a human's neck, comprising bellows plies (2, 3) being mainly perpendicular to the axis of the collar or of the human's neck. Free standing, the structure stands up around the neck to provide ballistic protection. The structure may be formed by folding a sheet of ballistic rated body armor fabric comprising strong synthetic fibers, e.g. from aromatic polyamide fibers, or ultra high molecular weight polyolefin, e.g. polyethylene polypropylene, fibers. For manufacturing the ballistic collar a plurality of sheets may be piled-up and the whole may be submitted to transformation in a mold (5, 6) at a temperature and pressure at which the sheets remain mainly loose from each other. Preferably parts of the collars or bellows shaped members are made, which are assembled afterwards e.g. by stitching, welding etc.
