Abstract: Integrated blackjack hole card readers and chip racks, and novel locking cover assemblies, are disclosed. In one embodiment, a chip rack of standard configuration is provided, and defines a cutout into which the reader can be placed. In another embodiment, the chip rack and reader are molded as a single unit. A removable locking cover is also disclosed which can be used to cover chip racks any time they are not in use.

Abstract: A back scattering collector, comprising: a first spherical reflective surface; a second spherical reflective surface having an annular form defining a central aperture; a refractive element, the first and second reflective surfaces and the refractive element being aligned along an optical axis; a light excitation source for illuminating a volume for analysis; the first and second reflective surfaces having respective diameters which reflect light rays back scattered from the volume at least three times between the first and second reflective surfaces, a last one of the at least three refections directing the light rays through the refractive element; and, a photo detector, the refractive element focusing the light reflected light rays onto the photo detector. The second reflective surface can be formed on the convex side of a plano-convex lens, the refractive element being formed by a central portion of the lens. The distance between the reflective surfaces is adjustable.
