Abstract: A retroreflective structure is described in which an array of transparent prisms is formed on a release coating of a sheet. The fact side of the prisms is made reflective and the prisms are either released to form a plurality of individual retroreflective structures or the array is adhered to a supporting substrate and then released from the base sheet. In the latter case, the array can be applied to a pre-existing structure formed of compatible fabrics, such as tarpaulins.

Abstract: A retroreflective structure having prism elements and a method for making the structure are disclosed. The retroreflective structure is formed of an extensible, elastomeric film and a rigid, non-extensible array of retroreflective prism elements. The array is bonded to the elastomeric film, thereby forming a retroreflective structure which can be significantly stretched without significantly diminishing the retroreflective properties of the structure.

Abstract: An aquatic exercise device is provided having a housing with a convex front wall and a concave rear wall, a top surface and a bottom surface. The front wall and rear wall have attached thereto preferably a harness to permit the towing of the device. The housing has a first interior cavity, a second interior cavity, and a water inlet valve, with both the second interior cavity and the water inlet valve having closures. The water inlet valve depends downwardly from the bottom of the housing. The second interior cavity has a compartment having a wall with an aperture therethrough, through which aperture is inserted a hose member having two ends. One end extends through the aperture into the first interior cavity while the other end has air passage therethrough regulated from an air flow control valve. The top of the housing has fixed thereto a flag pole with a preferably brightly colored flag.
