Abstract: There is provided an array of light emitting elements integrated with meta-surfaces. The meta-surfaces are constructed from a semiconductor alloy comprising at least two different semiconductors. The composition of the semiconductor can be varied so as to provide different refractive indices. A method of manufacture of such an array is also provided.

Abstract: A system includes a container assembly comprising a cover threadingly coupled to a container along a threaded interface portion of an interface and a cover lock assembly. The cover lock assembly includes a lock screw configured to selectively move between a cover lock position and a cover release position. The lock screw extends across the interface to resist threaded rotation of the cover relative to the container in the cover lock position, and the lock screw is recessed away from the interface to enable threaded rotation of the cover relative to the container in the cover release position. The cover lock assembly also includes a lock insert configured to block movement of the lock screw from the cover lock position to the cover release position.
