Abstract:
The invention provides a helmet being cooled inside by means of the Peltier effect, the helmet includes: a hard outer shell layer (10) and a shock absorbing padding layer (20) inside the hard outer shell layer (10) there is at least one through-hole (23) at their top area; a plurality of the air guide channels arranged in the inner side of the shock absorbing padding layer (20) communicating the through-hole (23) outwardly at the lower edge of the shock absorbing padding layer (20); a radiator (31) tightly seals the through-hole (23) on the outer surface of the hard outer shell layer (10); a Peltier module (30) arranged inside the through-hole (23) so that a hot side (302) is adjacent to the radiator (31); a solar panel (40) connected to supply power to the Peltier module (30).
Abstract:
The invention is a thin textile garment worn between the head and the motorcycle helmet. The garment forms an independent secondary liner between the helmet and the rider's head and looks in appearance like a balaclava. The garment is made of a material which has a central layer of water absorbent material with the inner surface in contact with the wearer's head being hydrophobic so that it is dry to the touch and the outer surface in contact with the air stream being hydrophilic to allow evaporative cooling from the water retention layer. The absorbency and thickness of the water retention layer may be selected to provide a predetermined period for cooling preferably an hour's cooling or more depending on conditions. The water absorbent liner is composed of microfibres.
Abstract:
A helmet (10) is coupled to a peltier element (12). One side of the peltier element (12), the cool side, is coupled to a gel form (14) that is coextensive with the entire interior surface of the helmet (10). This gel form (14) encases the skull, inducing localized hypothermia when power is supplied to the peltier element (12). The hot side of the peltier plate (26) faces outward. The heat is dissipated through a vent in the top of the helmet (10). The helmet (10) can be used to induce hypothermia in skull trauma patients, or as a protective helmet (10) for disabled children, particularly those suffering from cerebral palsy, or in sports and exercise.
Abstract:
The flexible cooling fabric (10) has an injector (30) that is flat so that it can be maintained unobtrusively within the cooling fabric (10). The injector (30) has a flat electromagnetic coil (62) which surrounds an injection chamber (21). The chamber (21) receives pressurized fluid, but a spring-biased plunger (96) closes the outlet openings (102) to the chamber (21). The fluid of the electromagnetic coil (62) tends to center the plunger (96) within the chamber (21) to uncover the outlet openings (102), and the fluid flows toward a membrane (14) which is against the skin or other object to be cooled. The refrigerant gas boils due to the heat flux from the skin, and this results in rapid and efficient cooling. The present invention also includes a system for recycling spent refrigerant gas.
Abstract:
A helmet with a mechanism for cooling comprises an inlet for allowing external air to flow into air pathways in the helmet, and a pad to hold moisture (liquid) to cool the air after the air has entered the helmet via the inlet. The helmet also contains a reservoir to hold the liquid, and a channel from the reservoir to the pad to transfer the liquid for providing moisture to the pad. Flowing air, cooled by the moistened pad, provides cooling to the wearer of the helmet. In an embodiment, a headgear includes a helmet and a cooling unit. The cooling unit is designed to be attachable to, and detachable from, the helmet by the user during normal use of the headgear.
Abstract:
A personal protection system that includes a headband (52) to which a face shield (38) is mounted. A cooling strip (120) is mounted to the headband. The cooling strip includes at least one thermoelectric cooling module (150). A draw strip (128) formed from a flexible thermally conductive material is also part of the cooling strip. The draw strip is bonded to the heat absorbing surface (152) of the thermoelectric cooling module and extends outwardly from the module. A biasing assembly (134, 186) urges the portions of the draw strip spaced from the thermoelectric cooling module against the skin of the individual wearing the personal protection system.
Abstract:
Headwear comprises gas storage means connected to means for distributing the gas from the gas storage means to other parts of the headwear at a reduced temperature.
Abstract:
There is disclosed headwear comprising an endothermic reactor and a trigger to initiate an endothermic reaction in the reactor whilst being worn on a wearer's head. Such may preferentially be utilised in or in conjunction with a motorcycle safety helmet or similar crash protection device. The headwear is intended to prevent or delay the onset of brain damage as a result of serious trauma or head injury.
Abstract:
A helmet (12) includes a thermoelectric heat pump (14) mounted onto a rear surface of the helmet shell (12) for delivering temperature conditioned air to the interior of the helmet shell. A multi-layer structure (48) on the helmet shell interior distributes conditioned air across the scalp and directly onto the face. An optional scoop (38) directs ambient air to the heat pump (14). Another version locates the heat pump (68, 84) remotely and conditioned air is transmitted to the helmet apparatus (70, 78) via a 10 flexible conduit (72, 85).
Abstract:
The use of a thermoregulating composition of matter, such as DRiWATER(R), to help thermoregulate a subject user is disclosed. In preferred embodiments, the composition can be situated over significant surface area portions of the user's body (such as by garment-like coverage of substantial portions of the user; on the torso, arms, legs, head, etc., for example) or it can be situated at discrete locations (such as by packs or packets of the material at strategic, heat-intensive areas of the user, for example). Additionally, the composition can be delivered by a variety of means (e.g., directly or indirectly, contained within packets made of either breathable or closed cell material, etc.) to provide the thermoregulatory effects, according to preferred embodiments of the present invention.
