Patent Document ID: 5495574
Application ID: 08277980

Base Claim:
1. A digital fuzzy inference system having a plurality of fuzzy rules comprising: means for inputting at least two binary data; means for inputting parameters for an if-part membership function represented by a line having a combination of gradients, each parameter including a tangent of a gradient and a point of change at which the gradient of the line changes, and each parameter being input for each of the fuzzy rules and each of the binary data; means for producing if-part membership values corresponding to the binary data in accordance with the parameters inputted by said parameters inputting means; means for obtaining a minimum value of the if-part membership values for each of the fuzzy rules; means for obtaining an inferential result in accordance with the minimum value for each of the fuzzy rules; and means for obtaining a center of gravity of inferential results for all the fuzzy rules.

Claim 7:
7. The system according to claim 1, in which said if-part membership values producing means comprises means for defining a membership function having a triangular shape in accordance with a single point of change and two gradients and means for calculating the if-part membership value by means of the binary data and the triangular membership function.
