Abstract: A strap assembly capable of engagement with an object (101) includes a strap (110) having a first end (111) and a second end (112), and further includes a buckle (120, 190) coupled to the strap. The buckle includes a cover (210) and a base (220) adjacent to the cover, and the base includes a slot (221) and an engagement aperture (122). The object with which the strap assembly is engaged has coupled thereto an attachment piece (102), which may take the form of a post (141) topped with a cap (142). The strap extends through the slot, the engagement aperture is capable of engaging the attachment piece, and the buckle is capable of rotating about the attachment piece when the engagement aperture is engaged with the attachment piece.

Abstract: A new simulator of the human head and animal bodies mimics moisture transpiration from eyes and skin and heat emission. The present invention used to demonstrate and quantify anti-fogging performance of goggles and apparel. Thin water permeable membranes are mounted onto a container containing a thermostatically controlled, heated and stirred reservoir of water as a simulation of the moisture source of the human eyes and skin. A light source and optical mesh patterns help illuminate water condensation on the inner lens of the goggles. The simulator results in a reliable and convenient demonstration and testing system for moisture condensation in goggle lenses, and heat and moisture apparel.
