    • A reel mechanism for use in a gaming machine including an integrally formed stepping motor/encoder assembly operatively coupled to a rotatable reel having an annular row of various symbols which are to be sequentially displayed in a visual field. The stepping motor/encoder assembly includes an integrally formed encoder wheel and sensing means. A processor/controller is operatively coupled to the stepping motor/encoder assembly for controlling the stepping motor drive signals, reading signals from the sensing means and storing in an associated memory a plurality of encoded reel stop positions which are a representation of physical stop positions on the reel. The processor/controller signals the stepping motor to spin the reel and while the reel is spinning, a random number generator means associated with the processor/controller determines a reel stop which corresponds to a specific position of a the reel. Simultaneously, the processor/controller cooperates with the integrally formed encoder means to provide a precise and fast response time in determining reel spin direction and absolute reel position to precisely control the stepping motor drive signals to stop the reel such that a portion of the annular row of various symbols which is associated with the reel stop determined by the random number generator means properly appears in the visible field.

    • In order to set up a height raster image for the inspection of complex units, for example of equipped printed circuit boards, optical distance sensors are employed. In this case, the known triangulation method or the likewise known confocal principle is employed. A sensor which permits a complete inspection in an acceptable time must cope with an appropriately high data rate. To this end, a distance sensor is described, which at the same time exhibits a high resolution and a low sensitivity in relation to secondary light reflexes. The essential features reside in: 1) a measurement beam (19) which is shaped to be substantially larger than the illumination beam (18) with respect to the diameter; 2) an approximately equal diameter of the two beams at the measurement location, the illumination beam (18) exhibiting a greater depth of focus (T) than the measurement beam (19), 3) a beam splitting unit (154) for splitting the measurement beam (19) with approximately point photodetectors which are disposed in each partial beam and which are disposed one behind the other in the direction of the partial beams and the respective height level within the depth of focus (T) is recognizable by the photodetector with the greatest light intensity.

    • Testing techniques for three-dimensional testing of printed circuit boards overcome the disadvantages that presently exist such as, for example, too little height resolution, low processing speed and difficult manipulation. The testing in the microscopic domain occurs within unaltering, displaceable evaluation windows on the basis of the calculation of cross-sectional areas at each scan point on a printed circuit board. Microscopic testing occurs on the basis of the calculation of defined, simple geometric values within a scan field and by following comparisons to reference values. The arrangement for the implementation of the methods utilize a laser scanner for triangulation, an evaluation unit, and at least one high-resolution, position-sensitive detector.
