Abstract: A turf tray supports live turf on a growth medium within a contained structure. The turf tray includes a base and walling that encloses at least a portion of a perimeter of the turf. The base defines a drainage area through which liquid seeping through the turf and growth medium drains from the base. A floor of the base slopes toward the drainage area to direct the liquid for drainage. Ridges project upwardly from the sloped floor and support a liner that receives the growth medium, the ridges maintaining the liner above the floor to provide an airflow gap. Adjacent ridges define channels along which the liquid flows toward the drainage area. Ridge heights vary relative to the slope to support the liner in a common plane. A receptacle underlying the drainage area collects drained liquid and is removable for disposal. The turf tray includes interconnecting tray components.

Abstract: A fiber optic clamp assembly for use with an ultra-precision translation stage to precisely align a fiber optical bundle with a laser diode mounted in a sealable enclosure, comprising a housing for receiving the fiber bundle, a flexible seal positionable between said housing and said enclosure; and a pressure collar for urging the seal against the enclosure, said collar being freely movable within the housing so as not to load the translation stage when the housing is being moved by the translation stage to align said bundle with said laser diode and thereafter being movable to compress the flexible seal without disturbing the alignment.
