Abstract: A reel-type slot machine includes a microprocessor driven game control circuit for randomly selecting a game result. Three reel assemblies each include a symbol-bearing display reel driven by a stepper motor for displaying game symbols corresponding to the game result. A series of signals representing potential game results is repetitively generated within the game control circuits. Upon user actuation of a spin switch one of the game results is randomly selected for application to a look-up table wherein the corresponding three game symbols to be displayed are identified. The number of repetitions of a potential game result in the series establishes a time window of availability for the result, and hence the probability of that game result being selected. After the three game symbols have been identified, the display reels are driven by their respective stepper motors to display the game symbols. Optional ramp-up and ramp-down circuits provide improved stopping accuracy.
Abstract: A clamping mechanism for mounting a circuit condition monitoring device to electrical cables of various diameters includes a core member comprising a plurality of laminations arranged in a generally rectangular configuration. A spring spanning the core member is anchored at one end to the core at a point near the housing of the monitoring device and at the other end is attached to a bridging member affixed at the opposite end of the core near the housing. This allows the spring to expand less as it transverses the bridge in order to accommodate different power cable diameters.
Abstract: A reel-type slot machine includes a microprocessor driven game control circuit for randomly selecting a game result. Three reel assemblies each include a symbol-bearing display reel driven by a stepper motor for displaying game symbols corresponding to the game result. A random number generator within the game control circuit generates a random number within a predetermined range of random numbers for application to a look-up table wherein a game result consisting of three game symbols is identified. Each potential game result is associated with a subset of random numbers within the total range of random numbers. The size of the subset determines the probability of the game result occurring. An undesired game result may be avoided by providing no corresponding subset. After the game result symbols have been identified, the display reels are driven by the stepper motors to display the game symbols. Optional ramp-up and ramp-down circuits provide improved stepping accuracy.
