Abstract:
The present invention provides portable hydrogen generators (100, l00a-l00e, 500) with portable cartridges (110, 510) containing a hydride and/or borohydride. The borohydride (132,132a) and hydride (134,134a) can be configured in a two-stage configuration or a three-stage configuration with an additional Li hydride (136); the hydride or borohydride can also be powder (530) disposed in a multi-cellular cartridge (510). Water for hydrolysis of the hydride/borohydride is supplied as mist through a mist nozzle (182, 182a), as steam when the water supply is internally heated by exothermic reaction after an initial hydrolysis of has taken place, or as stoichiometric doses releasable by puncturing a bladder (526) or by activating a valve connected to a water receptacle (526a) disposed inside each reaction chamber.
Abstract:
The present invention provides a protective vest (100, 100a, 100b, 100c) with a cool spreader (150), hot spreader (160) and active cooling mechanisms (200). The protective vest may be used with a uniform (1000), which incorporates passive cooling mechanisms (2000). Each active cooling mechanisms (200), including a TEM (210), a heat pipe (230), a heat sink (240), an insulator (250) with plenums (260) and a blower (270), is controlled by a micro-controller (280) and an adaptive algorithm (285) in response to three temperature sensors (290, 292, 294). The passive cooling mechanisms (200) include super absorbent polymer (SAP), phase change materials (PCM), phase change composites (PCC) and thermal conductive fibres (1040); when wetted, the SAP, PCM or PCC expands cyclically and gives rise to cyclical regenerative cooling.
Abstract:
The present invention provides a modular heads-up augmented reality (AR) display system (100, 100a, 100b) that is removeably attached onto a host spectacle (10) or onto a helmet (15). The AR display system includes a processor module (110), a battery module (170), a trunking module (180) disposed between the processor and battery, and a display (projection) module (200). The display (projection) module is pivoted onto the processor module in an extended position (to provide AR view 300) or in a retracted position (for full reality view 300a). User interfaces of the AR display modes are intuitive and help to reduce cognitive load on the user. The AR display system provides a choice of realtime or autonomous control of an unmanned forward equipment (103). When configured for autonomous control a drone (103b), a multi -modal controller (400) allows the user a choice of voice control (1420), gesture control (1430) or brain sensory control (1440).
