Abstract: A recreational gaming machine, is provided having an electro-mechanical apparatus that tosses a fair coin type object such that the outcome of the tossing process is unpredictable. A sensor determines the heads or tails outcome of each coin toss with a system that allows a player to place wagers.

Abstract: A rigid holster for retaining a pistol or handgun of specific design configuration has a locking pin that engages into the trigger guard ring area when the handgun is contained in the holster, thus retaining the handgun in place. To release the gun a user pushes a thumb pad which slides forward to release the locking pin. Other release mechanisms are disclosed.

Abstract: An underwater imaging system includes an underwater imaging polarimeter that captures images of the water surface. The captured images are indicative of the captured light, and are equivalent to four-component Stokes vector S=(I,Q,U,V) data. Advantageously, the passive imaging technique of the present invention utilizes polarmetric data. In contrast, conventional optical remote sensing techniques rely on light amplitude and frequency to carry information about the scattering surface. The imaging technique of the present invention exploits these properties, as well as the polarization properties of light to sense information about the scattering media. The two-dimensional slope field of surface wave can be recovered from a distance without interfering with the fluid dynamics of the air or water. By employing the physics of light scattering by a specular surface, the geometry of the surface can be found by measuring the polarimetric properties of the reflected and/or refracted light.

Abstract: Detergent compositions containing particular species of sulfonated zinc phthalocyanine were found to be unexpectedly effective bleach photoactivators for removing stains from textiles. These species are principally tri- and tetra-sulfonates, especially the latter, with minor amounts of di-sulfonates permitted.
