Abstract: The present disclosure describes novel systems and methods for converting a faceted room with into a cyclorama. Four system embodiments, “EMB1,” “EMB2,” “EMB3,” and “EMB4,” are disclosed and have several common elements, including a corner coving piece (“CCP”) and a bridging coving piece (“BCP”). EMB1 and EMB2 further comprise elements that collectively facilitate the alignment of adjoining pieces to form a seamless topology. EMB3 is a more basic embodiment that trades some alignment provisions for improved manufacturing simplicity and lower cost. EMB4 is distinguished by an embodiment where the main system elements can be fabricated from readily available materials by a non-expert using basic household tools; a method is disclosed herein to describe the construction steps as part of the overall process of converting a faceted room into a cyclorama. The two final disclosed methods guide the use of EMB1 or EMB2 for coving.

Abstract: This invention relates to condoms, prophylactics and contraceptive devices having a thick shape-retaining sheath body with an open end and a closed end, and a plurality of longitudinal flutes on the sheath body.

Abstract: This invention relates to condoms, prophylactics and contraceptive devices made of silicone rubber having a body comprising a plurality of sections that are capable of folding telescopically, such that each section folds into an adjoining section.

Abstract: This invention relates to a condom made of silicone rubber having interlocking rings for holding the condom in a collapsed configuration to facilitate insertion.

Abstract: This invention relates to condoms, prophylactics and contraceptive devices made of silicone rubber having a body with an open end and a closed end, a first collar proximate to the open end, a second collar adjacent to the first collar, and a series of accordion pleats on the body, wherein the accordion pleats can independently expand or contract.
