Abstract:
A micro unmanned aerial vehicle or drone ("UAV") 10 is remotely controlled through an HMI (309), although this remote control is supplemented by and selectively suppressed by an on-board controller (302). The controller operates to control the generation of a sonar bubble that generally encapsulates the UAV. The sonar bubble, which may be ultrasonic in nature, is produced by a multiplicity of sonar lobes generated by specific sonar emitters associated with each axis of movement for the UAV. The emitters produce individual and beamformed sonar lobes (80-102) that partially overlap to provide stereo or bioptic data in the form of individual echo responses detected by axis- specific sonar detectors (40-68). In this way, the on-board controller is able to interpret and then generate 3-D spatial imaging of the physical environment in which the UAV is currently moving or positioned. The controller is therefore able to plot relative and absolute movement of the UAV through the 3-D space by recording measurements from on-board gyroscopes (342), magnetometers (344) and accelerometers (346). Data from the sonar bubble can therefore both proactively prevent collisions with objects by imposing a corrective instruction to rotors (12-18) and other flight control system and can also assess and compensate for sensor drift.
Abstract:
A modular body armour system (100) includes an upper shoulder harness (102) in which shoulder straps (106, 108) are pivotally rotatable relative to each other and also to front and back connecting bridges (112, 114) that define a closed loop for the harness (102). Armour plates (124, 126) are attachable to the bridges (112, 114) and extend generally downwardly to protect the front and back torso regions of a wearer of the body armour (100). Pivotal articulation of the body armour (100) permits the armour to roll advantageously with the movement of its wearer such that movement, such as crouching or the adoption of a firing position, is not generally restricted. A lower girdle (104) incorporates additional plates and panels (140, 142, 105, 152) to provide enhanced protection to the wearer, which lower girdle (104) may be entirely independent of the upper shoulder harness (102). By providing for chest expansion through an elasticated connection within both the shoulder harness (102) and the lower girdle (104), a wearer is placed under less physiological stress during times of exertion and mental stress, thereby improving the overall performance of the wearer.

Abstract:
A flexible substrate (42) is fashioned into the form of a heat regulating jacket (100). Generally, an array of heat regulating channels (74, 76) is formed in an interior surface (72) of the flexible substrate (42). The interior surface (72) of the substrate is closest to a body that is to be cooled or heated by the jacket (100). Adjacent heat regulating channels (74, 76) are separated by bridging material (78). On an opposite, exterior side (44) of the substrate (42), a fluid distribution manifold (46) is formed to include at least one distribution channel (48, 50). The distribution channel (48, 50) is constructed so that it is substantially impermeable to heat regulating fluid, such as cooled or heated air, flowing through the distribution manifold (46). A through-hole (79) between the distribution channel (48, 50) and the heat regulating channel (74, 76) ensures that the heat regulating fluid is communicated across the flexible substrate (42), while the bridging material (78) ensures that the through-hole (79) is both cushioned from and spaced away from an outermost face of the interior surface (72).
Abstract:
An evaporative cooling device (40) is disclosed for cooling water or other liquids comprising a vessel (50) adapted to receive water or another liquid, said vessel comprising a vessel wall (53, 54, 55), an outer layer (90) of absorbent material and a wick (85) extending through said vessel wall, such that said wick is positioned to contact said water or other liquid within the vessel and is adapted to transport a portion of said water or other liquid through the wall by capillary action to said absorbent material, said wick being substantially impermeable to gas or vapour, so that the cooling device (40) can be connected in-line in an hydration system of the kind comprising a reservoir (12) and a drinking tube (32). Water or other liquid transported from within the vessel to the outer layer by said wick is absorbed by the absorbent material, from which it evaporates, the latent heat required for such evaporation being removed from the water or other liquid disposed within the vessel as sensible heat through the vessel wall, thereby cooling such water or other liquid. In some embodiments, the cooling device (40) may be fan-assisted. Also disclosed is a cooling garment comprising a garment portion that is adapted to be worn by a user and an evaporative cooling device (40) for cooling water or other liquids that are circulated through integrant channels or tubes provided in the garment.

Abstract:
The field desk includes a cabinet 51 having a top 84 rotatably connected with an extensible worktop. The worktop has two leaves 110, 112 hingedly connected to sides of a central section 92. A swivel or twist of the rotatable coupling allows the worktop to be turned between a first position, where the hinges are supported by the top 84 of the cabinet 51, and a second position, where the leaves 110, 112 can be rotated downwardly to seal the front and back of the cabinet 51, which may form a transport cube. The leaves 110, 112 may be held in the second position by connectors or magnets. The cabinet 51 may include removable closure boards 76, which can include sound-proofing, a white or pin board, an electronic display or ballistic panel, and can be erected onto the worktop. The cabinet 51 may be a cupboard or set of drawers. The closure boards 76 may be stored in a drawer and may partially seal an upper opening in the drawer.
Abstract:
-H A protective undergarment, shown in the form of shorts, includes integrally formed protective panels that exhibit slash-proof properties. The protective areas are made from 5 a flexible Kevlar* knit or the like, and extend to cover the groin, crotch, substantial areas of the buttocks and the inner thigh regions of both legs. The protective panels are externally snitched to a low thermal burden material, such as a polyester mesh, that provides elasticity and completes the structure of the shorts. The Kevlar* knit is flexible and preferably lies directly against the skin of a user to provide blast wave and ballistic 10 fragment deflection whilst permitting mobility in a lightweight arrangement. Varying thickness of the Kevlar* knit can be used in the protective areas selectively to enhance protection against blast wave and fragment penetration. The shorts find particular application in battlefield theatres where military personnel are exposed to bomb threats.
