A protective apparel support system is disclosed comprising a support frame configured to rest on the shoulders of a wearer, the support having a first shoulder member, a second shoulder member and a shield engagement portion. A shield is selectively coupleable to the support and protective apparel is coupled to the shield.

A breathable garment for heating or cooling independently the body of a wearer. The breathable garment includes an inner electrically heatable substrate intended to be facing the body of the wearer in use; a forced air supply mechanism for supplying forced air into the space between the inner electrically heatable substrate and the body of the wearer; an intermediate perforated substrate; an outer waterproof, water-vapour-permeable substrate; and a mechanism for maintaining a gap between the intermediate perforated substrate and the outer substrate, making up an air chamber to allow turbulent airflow across the entire garment.

There is also provided a self-sustainable body-cooling garment for cooling a body portion of a human or an animal adapted to use the air pumping footwear and a cooling system for cooling the human or animal's body. There is provided a footwear comprising an air pump adapted to pump air when worn by a human or an animal during a pedestrian movement and to store or direct the pumped air for use by a cooling system for cooling the pumped air and using the cooled air for cooling the human or the animal. There is also provided a cooling system comprising an air pump adapted to be embedded within a footwear and a nozzle adapted to cool air pumped using the footwear when worn by a human or animal during a pedestrian movement.

A protective clothing includes a first entrance in the front portion of the protective clothing, an operable portion in the hip section, two sleeve sections formed to the upper portion of the protective clothing, two leg sections formed to the lower portion of the protective clothing, multiple air orifices formed in sleeve sections and leg sections, a head mask removably connected to the upper portion of the protective clothing and having a transparent window, and an air blowing device attached to the protective clothing. The air blowing device sends air into the protective clothing, and the air releases from the air orifices to cool down the inside temperature the protective clothing.

An inflatable cold-weather upper-body garment. The garment includes first and second pluralities of interconnected gas flow chambers, each plurality enclosed by gas-impermeable material; a fluid-flow channel connecting the first and second pluralities of gas flow chambers; and a hand-operable air pump in fluid communication with one of the gas flow chambers.

Cooling suit including legs, torso and arms, which includes outwardly opening hose sleeve in the hip area, inwardly branching gas ducts having several outlet openings. A pressurized gas cylinder for carrying along and connecting outlet hose with coupling piece to this hose sleeve, and which comprises a valve and adjusting wheel for the regulated delivery of expanded gas into these gas ducts. The gas ducts in the upper-body have outflow openings in the area of the lower back, hips, neck area, armpits, arm joints, and sleeves. In the lower-body garment, outflow openings are arranged in the knees and the crotch area. This cooling suit is operated with a dry, compressed gas. The gas flowing from the pressure cylinder is expanded, subsequently cools down and then flows through the gas ducts and cools the body. Perspiration is carried away by the permanent gas supply via the breathable fabric of the suit.

An air-conditioned clothing for use with a helmet which can be used when the helmet is worn as well as when the helmet is not worn, includes a clothing main body, at least one fan, an air blow-out unit, a guide sheet and an attachment unit. The air is made to flow through an air flow path by the at least one fan and the flowing air evaporates sweat coming out from a body to cool the body with heat of evaporation and in a case where the helmet is worn, the air which blows out from the air blow-out unit is guided to the helmet by the guide sheet and taken into the helmet from an air intake which is formed between an inner edge of the helmet and the head of the user in order to circulate the air inside the helmet.

An example face shield includes a face shield lens comprising a locking channel, a face shield shell configured to receive the face shield lens when the face shield is inserted into the face shield shell, and a lens lock configured to move between: a locked position in which the lens lock is configured to engage the locking channel of the face shield to secure the face shield lens to the face shield shell; and an unlocked position in which the lens lock is configured to disengage the locking channel of the face shield to permit insertion of the face shield to the face shield shell and removal of the face shield from the face shield shell.

A lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

A fan unit for an air-conditioned garment, wherein the fan unit takes external air into an interspace between the garment and a wearer's body, the fan unit including: a fan that blows external air into the interior of the garment; a motor that rotates the fan; a battery that supplies power to the motor; a charging terminal for charging the battery; and a power switch to start and stop the fan unit, wherein the fan, the motor and the battery are housed in a casing, the casing has an air intake port that takes in external air, and an air blowing port that blows the taken-in external air into the interior of the garment, the charging terminal and the power switch are provided on the exterior of the casing, and the casing has a thickness of 5 to 30 mm in an axial direction of the fan.
