The housing may include a first surface configured to be placed in contact with the skin of the user and a second surface exposed to the fluid channel. The face engaging device may also include a thermal actuator supported by the housing and including a first heat transfer surface position on the first surface, where the first heat transfer surface is configured to apply a thermal profile to the skin of the user when the opening is placed in fluid communication with the mouth of the user.

A combined air filter and protective gown includes a protective gown; at least one tube; at least one air filter; a waist belt; check valves disposed at a face, two hands, and two ankles of the protective gown respectively; and ties for fastening the face, the hands, and the ankles of the protective gown respectively. One end of each tube is terminated inside the protective gown and the other end thereof is attached to the air filter. Each air filter is attached to the waist belt. Each air filter includes a centrifugal fan, a circuit board, a UV lamp, a filter element formed of activated carbon, a power supply, a housing for enclosing the centrifugal fan, the circuit board, the UV lamp, the filter element, and the power supply, and a cover threadedly secured to the housing.

A method of using an apparel power system is disclosed. The method uses an apparel accessory to be powered and an apparel adaptor to create an electrical contact between a vehicle and the apparel accessory. The apparel power system provides a source of electrical energy for electrically powered accessories attached or integrated to the apparel accessory worn by the user of the vehicle without requiring the use of wires and plugs connections between the user and the vehicle. Contact between connecting elements of each of the apparel accessory, apparel adaptor and vehicle allow the electrical power to be transmitted between the vehicle to the apparel accessory and thereof the electrically powered accessories.

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.

A high-pressure passthrough apparatus and protective suit having a high-pressure passthrough is provided. A high-pressure passthrough having a penetrator body is connected to a protective suit, wherein a first half of the penetrator body is positioned exterior of the protective suit and a second half of the penetrator body is positioned interior of the suit. A high-pressure passthrough valve is positioned on the second half of the penetrator body, wherein high-pressured air is supplied to an interior space of the protective suit. Releasing the quantity of high-pressure air to the interior of the protective suit with the high-pressure passthrough valve may act to cool the interior of the protective suit.

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.

The compression augmented full-pressure suit system includes a garment configured to protect humans in low to zero atmospheric pressure environments while providing excellent mobility. The suit system includes a specialized compression garment worn over the entirety of the body, with a full pressure suit over that compression garment. The compression garment applies a percentage of the pressure on the human form required for protection in low atmosphere environments. The balance of the pressure that is required comes from pressurization of the full pressure suit. Use of both pressure application methods concurrently enables each component to be greatly simplified in comparison to their configuration when used individually, with the result being greater comfort and performance at a reduced cost.

A respirator includes a frame, a filter layer, and a face seal member. The frame has an outer side and an inner side. The frame defines an opening therethrough. The filter layer is mounted to the outer side of the frame and covers the opening of the frame. The filter layer is configured to prohibit permeation of aerosol, gas, and/or vapor contaminants therethrough. The face seal member is mounted to the inner side of the frame. The face seal member includes a seal contact area configured to engage a facial surface of a wearer. The face seal member incorporates a phase change material therein. The phase change material is configured to provide localized cooling by absorbing heat emitted by the wearer.

A ventilated cooling and protective garment including a hood portion (31) with a facial opening (14) surrounded by a facial peripheral ring (13) and a complete or partial body portion (32, 33), and a facial shield (10) comprising a transparent shield (11) and a facial peripheral connector (12) supporting and air-tightly attaching the transparent shield (11) to the facial peripheral ring (13) around the facial opening (14), wherein the facial peripheral ring (13) is pulled against the head of the user by the facial shield support (20) and include spacers (13a, 13b) to provide a permeable close non-air-tight fitting between the facial peripheral ring (13) and the head of the used, and an air inlet (A1) is included in the complete or partial body portion (32, 33) and at least a portion of an air outlet (A2) is included in the facial shield (11), or vice versa.

An article of outerwear which resists ignition and insulates against heat, the article of outerwear has a plurality of sections made from a fabric, such as woven fabric, knit fabric or a combination thereof. The plurality of sections allow the article of outerwear to stretch enhancing the comfort of the wearer of the article of outerwear. The outerwear may include a protective shroud/hood which has fans to circulate air inside the protective shroud/hood, the fans having air intake openings and vent openings, the air intake openings opening in planes which are perpendicular to planes in which the vent openings open.
