Abstract: A device for mechanically assisting with scleral depression is disclosed. A top ring and a bottom ring are rotationally engaged where the bottom ring is capable of attachment to an eyelid speculum, and is thus fixed while in use. A variable vertical displacement apparatus is attached to the top ring. A rod and depressing member are engaged with the variable vertical displacement apparatus such that the depressing member is capable of both vertical and horizontal travel around the periphery of a patient's eye, allowing a surgeon to depress the sclera of a patient's eye while at the same time performing a surgical procedure.

Abstract: A portable optical measurement assembly for measuring the dimensions of an upper peripheral region of a wall structure of a swimming pool is provided. The assembly comprises an optical unit subassembly including an optical unit casing. The optical unit casing encloses a light source structured and arranged to direct a light beam onto an upper peripheral region of the wall structure of a swimming pool and a sensor structured and arranged to provide data indicative of the distance from the light source to the particular point on the upper peripheral region of a wall structure of a swimming pool surface. The portable optical measurement assembly also includes a mounting assembly for rotationally supporting the optical unit subassembly.

Abstract: A structure for forming a vertically orientated wall comprises a flexible front panel having a longitudinal axis, a transverse axis and substantially continuous front surface; a flexible rear panel positioned rearwardly and parallel to the front panel; and a plurality of cross members connecting the front and rear panels. The front and rear panels define an upwardly opening cavity therebetween for accepting filler material, such as concrete therein. The rear panel includes at least one longitudinally disposed laterally deformable portion, such as a channel or zig zag pattern, which allows for the associated expanding and contracting of the rear panel during adjusting of the arcuate configuration of the wall structure.
