Abstract: Ventilated suit embodiments are disclosed. The ventilated suit typically comprises a hood portion, four limb portions, an air inlet port, and an air distribution system in fluid communication with the air inlet port and attached to the back portion of the ventilated suit. The air distribution systems comprises at least five air pathways that extend into the four limbs and hood of the suit, with the air pathways being in fluid communication with the air inlet port to distribute air outward into the limbs and hood.

Abstract: Embodiments of the disclosure relate generally to protective clothing comprising one or more pockets operable to hold cushioning pads in strategic places on the clothing, such as knees, elbows, and shoulders, for example. Applicants propose an improved pocket opening design, comprising a first opening layer and a second opening layer offset from the first opening layer. The opening would not comprise any other fastening elements, such as Velcro, hooks, closures, zippers, etc. which may be easily damaged. The offset or distance between the two opening layers would allow for easy insertion of the cushioning pad, while also preventing a cushioning pad from accidentally coming out of the pocket. Additionally, the two layers would prevent dust from entering the pocket, when the opening is located on the exterior of the protective clothing.

Abstract: A low pressure warning device that comprises a piston located inside the device, where the piston partitions the device into a first chamber communicating with a first opening and a second chamber communicating with a second opening, an adjustable stop, and a spring located inside the device and configured to bias the piston to a position based on a position of the adjustable stop and based on a pressure differential between the first opening and the second opening, wherein a low pressure differential warning state is associated with a position of the piston.

Abstract: A safe ventilated breathing apparatus to be worn by people in an ambient medium where there is an atmosphere at a pressure Pa that is substantially constant. The breathing apparatus includes a covering constituted by a skin of leakproof material, a fluid feed tube having one end suitable for being connected to a source of fluid at a given pressure Pn greater than Pa, and having its other end passing through the skin via a leaktight passage so as to plunge into the covering, vent elements made in the skin to put the inside of the covering into communication with the ambient medium, and elements for visually warning the person when the pressure of the fluid in the feed tube drops below a given threshold value Ps, less than Pn. The invention is particularly applicable to safe ventilated breathing apparatuses for the nuclear, bacteriological, etc., fields, hospital environments, etc.
