The present system comprises a device which issues tickets, a central processing device and an entrance gate device which controls entry to the site. The central processing device establishes appropriate data representing the maximum carrying capacity of each attraction (i.e., the maximum number of reservations which can be given out). It does so by performing a fuzzy inference based on fuzzy rules using as fuzzy variables various uncertainty factors which influence cancellations and other events that transpire after a reservation is made, such as type of attraction, weather, time of day, day of the week and season.

Reservation media issuing system using fuzzy logic

A group control system in which a plurality of fuzzy controllers are interconnected by a communication line and the parameters of rules and membership functions of each fuzzy controller are capable of being adaptatively changed depending upon the state of the controlled system so as to improve the control performance of the overall system.

Fuzzy controller group control system

A safety distance measuring device employing an electromagnetic wave is provided. A laser diode 2 is energized to emit laser beams by a laser diode drive circuit 3 in accordance with a clock signal generated by a control circuit 29. The emitted laser beams are sequentially changed to predetermined scanning directions by a scanner 1 associated with control circuit 29. The scanned laser beams from scanner 1 are reflected by an object 19 to be received by a photodiode 5. An output of the photodiode is applied to control circuit 29 through a light receiving circuit 6 where an elapsed time from emission to receipt is computed to obtain a distance from scanner 1 to object 19. Based on data relating to scanning directions by a scanning position detector 4, a begin-and-end detecting circuit 28 can stop the radiation of electromagnetic waves around a scanning start point and a scanning end point which is danger to human bodies.

Electromagentic wave generating device and a distance measuring device

In a fuzzy controller comprising a fuzzy inference device for subjecting one or a plurality of input signals to fuzzy inference operations using membership functions in accordance with a predetermined rule and outputting a non-fuzzy value determined on the basis of the results of the inferences, there are provided an input signal level converter for converting signal levels of the input signals on the input side of the fuzzy inference device and an output signal level converter for converting a signal level of the output signal on the output side of the fuzzy inference device.
