The Strapless Mask assembly which serves as a personal protection equipment that protects against airborne diseases and viruses includes two parts, A fabric covering which incorporates pockets that covers the nose and the mouth which will holds a HEPA filter that provides extra respiratory protection, and a supporting concave curved frame that fits on the cheek bones, resting on the ridge of the nose and uses the jaw lining to secure itself in place referred to as the structural component. The frame member includes a downwardly extending projection in front of the ear. The fabric covering has a slot sewn along the top of the material which extends downward along each side of the covering. The double layer fabric sewn together allows for the frame to be inserted in the covering from the center of the mask.

A conductive assembly (10) includes a conductive fabric core (12) which includes at least one electrically conductive element woven with the fabric core, optionally first and second impermeable layers (14, 16) enveloping the fabric core (12), first and second spacer layers (18, 20) overlying or within the impermeable layers (14, 16) and first and second conductive shield or screen layers (22, 24) overlying the spacer layers. The shield layers are electrically coupled together in the preferred embodiment for electromagnetic shielding. The spacer layers (18, 20) provide a stable and uniform spacing between the shield or screen conductors (22, 24) and the conductive fabric core (12).

An article that includes a vortex-generator device may include various features. For example, the article may include a material layer and one or more elongate members coupled to the material layer. In addition, the one or more elongate members interconnect two or more vortex generators.

A ghillie suit manufacturing apparatus includes: a camouflage yarn feeding unit adapted to continuously feed camouflage yarns having different colors required for camouflage by a given distance from the left side to the right side and from the right side to the left side; a knotting unit adapted to tie the camouflage yarns fed from the camouflage yarn feeding unit on both side end portions of the camouflage yarns to form knots on both left and right sides of the camouflage yarns, while having given distances between the knots; and a cutting unit adapted to cut given portions of the camouflage yarns located between the knots formed on both left and right sides of the camouflage yarns by means of the knotting unit.

There are provided stretchable solid-state electroactive polymer actuators (SSEPA) using electroactive polymers that convert between electrical energy and mechanical energy and having solid-state polymer electrolytes. More particularly, there are provided electroactive polymer (EAP) compositions comprising: 15-60 wt. % of a film-forming polymer; 5-40 wt. % of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and 10-40 wt. % of a plasticizer, solid-state polymer electrolyte (SPE) compositions comprising: 20-60 wt. % of a plasticizer, 10-60 wt. % of a film-forming polymer and 5-25 wt. % of an ionizable salt. The use of these EAP and SPE compositions in electromechanical devices, such as solid-state actuators, generators, sensors, and other energy transducers in various applications are also disclosed.

A garment that includes one or more grip elements is disclosed. The grip elements, as disposed on a garment, may enable enhanced frictional forces between the garment and an object, such as exercise equipment, with which the garment may make contact. The grip elements may be composite structures disposed on one or more surfaces of the garment and may include an elastomeric and/or rubbery material with grit materials, such as sand, alumina, silicon carbide, or the like, embedded therein. The grit material may be at least partially exposed at the surface of the grip elements and may enhance gripping forces when the grip elements are wet, such as with sweat, compared to grip elements formed by only elastomeric materials. Grip elements may be formed on various portions of a garment separately and then those portions may be attached to each other to form the garment with grip elements.

A heat-management material that includes a base fabric having an externally facing surface and an internally facing surface; and a plurality of multilayered multifunctional heat-management elements coupled to the externally facing surface of the base material wherein the heat-management material has weighted average thermal emittance of less than 0.8 (or 80%). The multilayered multifunctional heat-management elements include a low thermal emittance layer and a high solar absorptance layer.
