Abstract: A personal protective device (PPE) including a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to rotate (either manually or by electric motor) the masks and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases, such as operation in more hostile environments. Features to improve user comfort, including alternate bodysuit designs, moisture reduction, and cooling are disclosed.

Abstract: [Problem to be Solved] To provide a vanadium active material solution which has a vanadium active material concentration of 2.5 M or more in a sulfuric acid solution including a dispersoid (suspensible material), can stably maintain high energy density based on the concentration, and can respond also to fast charge and discharge, and to provide a vanadium redox battery using the active material solution. [Solution] The above problem is solved by a vanadium active material solution comprising a vanadium compound, which is an active material, as a solute and a dispersoid, wherein the total concentration of vanadium is 2.5 M or more. Here, in a negative electrolyte, the vanadium compound comprises one or both of bivalent and trivalent vanadium. In a positive electrolyte, the vanadium compound comprises one or both of quadrivalent and pentavalent vanadium. In an active material solution, the vanadium compound comprises one or both of trivalent and quadrivalent vanadium.

Abstract: There is provided a glass unit and the process for making the same comprising at least two sheets of glass having an enclosed view control component, a spacer applied to the peripheries of the two sheets of glass to form a space between the two sheets of glass and a ultra-violet light activated photopolymer uniformly dispersed throughout the space formed between the two sheets of glass.
