Abstract: A slot machine allows the operation of two or more independent slot games at the same time. The two or more slot games may have the exact same game format or different game formats. Each slot game pays independently of the other slot game, but uses a common pool of credits. One player may play cooperatively with another player, or other players, at the same gaming machine; or one player may play two or more slot games at the same time on the same machine. By placing multiple slot games on the same machine, the amount of money deposited into the slot machine increases without taking up any additional casino floor space. Therefore, casinos, especially those with restricted floor space or limited quantities of slot machines, may generate higher profits per square foot and offer more games to their clientele.

Abstract: A dual beam acousto-optic tunable spectrometer utilizes an optics system to isolate the two radiation beams tuned by an acousto-optic filter, one of which is used to analyze a sample, the other of which is used as a reference. The tuning of the filter and the analysis of the signals is conducted by a microprocessor, which corrects for the many possible sources of noise. A new fluid sample cell utilizing glass balls to collimate radiation incident on the sample and focus radiation transmitted from the sample, is also disclosed.
