Abstract: Described herein are systems and methods for creating and operating a geodesic dome habitat. The geodesic dome habitat includes a frame system for providing structural support and at least one tile that attaches to a face of the frame system. The frame system includes a plurality of struts arranged along the edges, a plurality of tension cables arranged planar to the faces, and at least one connector arranged along a vertex. The tile may be a functional tile for performing a specific functional task, such as a functional tile that includes irrigation systems for irrigating plant receptacles in a vault enclosure, and/or a functional tile that includes thermal plates and outlets for fermentation. The geodesic dome habitat may be compatible with any number of functional tiles, electrical systems, furnishings, etc.

Abstract: A modular reusable elastomeric half-face respirator device includes a modular housing and an elastomeric facepiece. The respirator device can include one or more modular straps, which can be coupled to the filter housing or the facepiece. The modular housing includes a modular filter component configured to hold filter media and to couple to the facepiece. A filter retention mechanism includes an interlocking bayonet-type ratcheting ramp configured to form a seal around the modular filter component, the filter media, or both. The facepiece can include an interfacing portion configured to seal to the face of a person wearing the respirator device, the interfacing portion having a geometry with an outward curvature allowing the interfacing portion to seal to the face by rolling back and increasing contact area between the facepiece and the face. A lock ring receivable in a port of the facepiece can couple the facepiece to the filter component.

Abstract: A lamp comprises a base, at least one light source arranged on the base, a cover positioned on the base and covering the light source, and a structured film arranged adjacent to the light source. The structured film has at least one micro structure configured for guiding part of the light backward emitted from the light source.
