Abstract: The present disclosure relates to methods of producing and purifying synthetic block copolymer proteins, expression constructs for their secretion, recombinant microorganisms for their production, and synthetic fibers comprising these proteins that recapitulate many properties of natural silk.

Abstract: Goggles provide various features including skirt that mounts to a frame of the goggles. The skirt may be elastic and may include damper portions at least partially extending into the elastic skirt to allow the elastic skirt to have travel and to thereby better conform to the facial features of a subject. The goggles may include an overhead mounting location such as a chamber that encloses movement, such as infrared light sources and/or cameras. Furthermore, the goggles may include infrared mirrors that are retained by a bracket mounted to the frame, where the bracket has a portion affixed to the frame that retains another portion that is movable and that is affixed to the infrared mirrors.

Abstract: Postural stability platforms include at least one movement resistant element Fixed to a base and coupled to a plate. The plate is movable relative to the base but the movement resistant elements resist movement of the plate. Accordingly, subjects standing upon the plate are provided a degree of stability. The movement resistant elements may include springs, hydraulic cylinders, pneumatic cylinders, electromagnetic solenoids, and the like. Furthermore, in certain instances, the degree of resistance offered by a movement resistant element may be adjusted, such as by operation of a valve, so that the stability of the plate upon which the subject stands may vary depending upon the needs of the subject.
