Abstract
Abstract A fuzzy reasoning computer having a multi-stage construction is disclosed which includes a primary fuzzy reasoning computer at a rank having a reasoning system for producing a reasoned result, at least one child fuzzy reasoning computer at a lower rank having a reasoning system for producing a reasoning result and a system for providing the reasoning results of the at least one child fuzzy reasoning computer to the reasoning system of the primary fuzzy reasoning computer in such a manner that the reasoning performed by the primary fuzzy reasoning computer is assisted by the at least one child fuzzy reasoning computer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
A fuzzy reasoning computer comprising fuzzy rule storage means for storing a plurality of fuzzy rule groups, wherein each said fuzzy rule group includes fuzzy rules having a consequent fuzzy variable which is the same, fuzzy rule group selecting means for receiving a request for a defuzzified output code that contains at least a defuzzified output variable code and for selecting from said fuzzy rule storage means at least one of said fuzzy rule groups which has the same consequent fuzzy variable as said defuzzified output variable code, input means for receiving external data to be applied to a fuzzy variable at an antecedent of each said fuzzy rules in said selected fuzzy rule group and reasoning means for producing a defuzzified output based on said received external data to be applied to a fuzzy variable at an antecedent of each said fuzzy rules in said selected fuzzy rule group.
Claim 2
Dependent Claim
150 words
A fuzzy reasoning computer comprising fuzzy rule storage means for storing a plurality of fuzzy rule groups, wherein each said fuzzy rule group includes fuzzy rules having a consequent fuzzy variable which is the same, fuzzy rule group selecting means for receiving a request for a defuzzified output code that contains at least a defuzzified output variable code and for selecting from said fuzzy rule storage means at least one of said fuzzy rule groups which has the same consequent fuzzy variable as said defuzzified output variable code, input means for receiving external data to be applied to a fuzzy variable at an antecedent of each said fuzzy rules in said selected fuzzy rule group and reasoning means for producing a defuzzified output based on said received external data to be applied to a fuzzy variable at an antecedent of each said fuzzy rules in said selected fuzzy rule group.
Claim 3
Dependent Claim
18 words
A fuzzy reasoning computer according to claim 1, wherein said external data is supplied from an external sensor.
Claim 4
Dependent Claim
61 words
A fuzzy reasoning computer according to claim 1, further comprising requesting means connected to said fuzzy reasoning computer for issuing a request for a defuzzified output corresponding to a fuzzy variable of said selected fuzzy rule at its antecedent, wherein said external data includes a defuzzified output given by a second fuzzy reasoning computer upon said request from said requesting means.
Claim 5
Dependent Claim
34 words
A fuzzy reasoning computer according to claim 1, wherein said reasoning means further comprises function means for representing membership function values corresponding to a fuzzy variable with pulse widths to form a membership function.
Claim 6
Dependent Claim
39 words
A fuzzy reasoning computer according to claim 4, wherein said reasoning means further comprises OR circuit means for receiving a plurality of signals representing said pulse widths by their simultaneous starting or ending points to generate a MAX signal.
Claim 7
Dependent Claim
29 words
A fuzzy reasoning computer according to claim 4, wherein said reasoning means further comprises AND circuit means for receiving signals of said pulse widths to generate a MIN signal.
Claim 8
Dependent Claim
27 words
A fuzzy reasoning computer according to claim 4, wherein said reasoning means further comprises truncating means for truncating said membership function by having an AND circuit means.
