Abstract: Life support systems include a pressure garment, a helmet, and a life support system enclosure that define an enclosed environment. The life support system includes one or more life support components to generate breathable gas within the enclosed environment. The gas is directed along a closed-loop flow path through the system. The life support components includes a fan for driving a flow of the gas through the closed-loop flow path and an acoustic damper arranged along the flow path and to reduce noise generated by the fan. The acoustic damper includes a housing defining an annular cavity arranged about a portion of the flow path, with the housing having a solid exterior surface and an inner diameter surface with openings to fluidly connect the flow path with the annular cavity and at least one acoustic damping element arranged within the annular cavity.

Abstract: A simulation system comprising: a plurality of physical components, each corresponding to one of a plurality of physical component types, an attachment panel comprising an arrangement of attachment locations, such that one or more of the physical components are attachable to the attachment panel; a display system configured to provide a visualisation on or proximate one or both of the attachment panel and the plurality of physical components; a capture device configured to capture image data of a current status of the attachment panel and the plurality of physical components; and a controller, when at least one physical component is coupled to the attachment panel.

Abstract: An adsorbent system includes a passage and first and second adsorbents in the passage. The first adsorbent includes granules of non-impregnated activated carbon and the second adsorbent includes granules of acid- or metal salt-impregnated adsorbent. The granules of acid- or metal salt-impregnated adsorbent have, by weight, at least 20% acid or metal salt content. The granules of acid- or metal salt-impregnated adsorbent have, by weight, at least 35% acid or metal salt content. The granules of non-impregnated activated carbon and the granules of acid- or metal salt-impregnated adsorbent have a size of mesh 4 to mesh 40, and, by total combined weight of the granules of non-impregnated activated carbon and the granules of acid- or metal salt-impregnated adsorbent, the first adsorbent has 55%-75% of the granules of non-impregnated activated carbon and the second adsorbent has 45%-25% of the granules of acid- or metal salt-impregnated adsorbent.

Abstract: A heat sink includes a core body. The core body defines a coolant plenum, sealed first and second chambers, and first and second coolant conduits. The sealed first and second chambers each house a phase change material. The first and second coolant conduits are separated from one another by the coolant plenum and are in fluid communication with the coolant plenum for transferring heat between coolant flowing through the core body and the phase change material.

Abstract: An adsorbent system includes a passage and first and second adsorbents arranged in series in the passage. The first adsorbent includes granules of non-impregnated charcoal and the second adsorbent includes granules of acid- or metal salt-impregnated adsorbent. The granules of acid- or metal salt-impregnated adsorbent have, by weight, at least 20% acid or metal salt content.

Abstract: A heat switch includes a heat sink, a coolant tube, and an actuator. The coolant tube is movable with respect to the heat sink. The actuator couples between the heat sink and the coolant tube and configured to move the coolant tube between a first position and a second position. Heat flow from the coolant tube into the heat sink is greater in the second position than in the first position for enhanced heat transfer from the coolant tube.

Abstract: A phase change material heat sink includes a sealed enclosure containing a phase change material. A fluid passage element is in contact with the sealed enclosure and includes a thermal exchange layer in thermal contact with the top and that directs fluid in a first flow direction and a shunt passage element in thermal contact with at least one of the sides or the bottom and that directs fluid in a second flow direction.

Abstract: An active sampler for detecting contaminants in liquids comprises an inlet tube, and outlet tube and a sampling unit positioned between said paths such that the liquid flows along a path from the inlet, through the sampling unit, to the outlet. The sampling unit has a plurality of sampling chambers that are substantially fluidly sealed relative to one another, wherein one of the sampling chambers is selectively positioned in the flow path. The active sampler also comprises an actuator, which relatively moves the sampling unit and the inlet and outlet tubes such that said one sampling chamber is positioned out of the flow path while another of the sampling chambers is positioned in the flow path.

Abstract: A massaging surface contains alternating rows of massaging elements, each element includes three resilient arms extending radially and upwardly in symmetry from a common base point on that surface and terminating in massaging balls for delivering long stroke massage when pressed against a skin of a patient. The massaging surface allows for administering uniform massage over a large area including longitudinal and rotational strokes due to overlapping of massaging areas of individual adjacent massaging elements.

Abstract: A massaging garment for a massage of a selected area of the wearer's body such as the lower back, the garment is activated by the natural movements of the wearer such as walking or running and comprises a belt covering a holding frame containing a plurality of rollers positioned over the massaging plate. The holding frame is reciprocally driven by a push-pull element attached to the thigh of the wearer while walking so that the rollers cause selective compression of the raised elements of the massaging plate and thus cause the desired massaging action over the wearer's body.

Abstract: A massaging element for delivering a long stroke massage, the massaging element having at least one pair of symmetrical arc-shaped spring elements extending from a central driving component and having replaceable massaging units such as rollers at their free ends. A driving unit delivers reciprocating motions to the central driving component causing compressing and outward movements of the massaging units. A power or manually driven massager incorporates a plurality of the massaging elements for a wide area massage of the patient's body. The massager is easily foldable for storage or transport.
