Dear Angione,

your design is interesting. Aptronix' Fide software tool
may be of help to your design.
in defuzzification, it uses both center of
gravity method (Mamdani method) and TVFI (truth-value
flow inference method patented by Aptronix), the lattter is
more than 100 times faster than the former.

for a copy demo of Fide, go to web site at
or go to

Fide info is attached.

RE: Fide - a graphical, object-oriented fuzzy software tool
for fuzzy and non-fuzzy engineers/scientist

Dear Customers,

Thank you for your interest in Aptronix products and services.
Out old BBS has been replaced by the Aptronix Web Site at which provides rich, updated information
on Aptronix products and technologies.

Aptronix, Inc. has recently announced the worldwide release of Fide
version 2.0 - Fuzzy Inference Development Environment. This
enhanced version features a richer set of GUIs and a number of
RTC (run-time code) generators for C, Java, MatLab and Assembly.
Fide 2.0.1 incudes a new Java RTC generator module that helps
develop "smart applets" for internet applications. Attached at
the end is "Fide Product Information" and "Fide RTC Data Sheet".

Fide is the ultimate solution to an integrated software tool for
fuzzy logic applications. Marketd by Motorola, Intel and Aptronix,
it has been used worldwide by over 4,000 customers in 35 countries.
Major customers include Motorola, Intel, Omron, Allen-Bradley, SRI,
HP, Luckheed-Martin, Loral, TRW, MacDonald Douglas, Northrop, Boeing,
US Navy Ordance, Navy Weapons Center, NASA, Livermore Berkeley Lab,
Ford, Chrysler, General Motor, GE Nuclear, Hughes Aircraft, Navigation
Technologies, Sony, Sanyo, Scientific Computers of France, InVision,
UC-Berkeley, Caltech, University of Toronto, HK University, Singapore
National University, Cairo University, the Northeatern University and
Dalian University of Technology of China, etc.

Recently Aptronix engineers have developed the Embedded Internet
technologies for intelligent Internet applications including software
agents, help-desk, networked expert systems, distribution control, etc.
Java Run-time code (RTC) generator will be freely upgraded for users of
Fide 2.0 High-level kit. In addition, the old Aptronix FuzzyNet BBS
(bulletin board system) is now replaced by the Aptronix home page at
Our web site provides rich information about Aptronix in
particular, and about fuzzy logic technologies in general, and
it will be updated constantly. So stay tuned.

Aptronix is committed to providing quality products and outstanding
support to you, our valued customers. Aptronix will continue upgrading
its products and services to assist costomers in their research and
applications. A Support HotLine (the number is 408-261-1898) has
been established to support Fide customers. We also welcome suggestions,
comments about Aptronix products and services. Customers and users
are encouraged to participate in the FuzzyNet forum in Aptronix home
page by providing application notes and other informaton regarding
fuzzy logic.

Thank you again for inquiring about Aptronix' products.

- A mouse
II. Fide 2.0.1 Features
- a Fide package includes a 3.5 inch disk and a set of 3 reference books:
User's Manual (290 pages): fuzzy tutorial, examples, complete guide
Reference Manual (108 pages): details of Fide usage
Quick Start Quide (38 pages): brief guide for starters
*note: reference books can be sold separately from the software.
- almost no limits on the size of applications
up to 256 labels per variables
up to 256 variables
up to 8,100 rule statements per inferenc unit (FIU)
up to 16,320 labels per inference unit.
- inference methods:
Mamdani, or
TVFI (truth value flow inference, the Aptronix patented technology
- operators:
min, max, probability product and sum, intersection, union
- defuzzification methods:
centroid, leftmost-, rightmost- and average maximizers
- built-in editors:
graphical and text editors
- membership function editor:
graphical editing of membership function (MF) shapes
triagle, polygon, cubic, freehand drawing
produces MFs by modifying existing MFs
- rule matrix editor
rule matrix editor is an effective maens for rulebase development
rule macros allow large systems to be developed efficiently
- debugging environment:
MCU environment - simulate characteristics of specific chips
- debugging tools:
tracer - allows isolating a portion of FIU transfer function and
quickly tracing back to the rulebase (rule statements)
analyzer - present several graphical representations of a FIU
transfer function; automatically trace a point from its
graphical representaion to its source code; provide cross
section, coutour (projection), and control surface.; gives
a global view of the transfer function response.
- signal generators:
generate a wide range of functions to drive the simulator,
including sine, cosine, exponential, step function, ramp,noise...).
- simulator:
presents fuzzy units in time domain. includes built-in signal
generators reads in step inputs and plots simultaneously the time-varying
curves of both inputs outputs on the same frame for comparison of
convergence, discountinuities, and phase relationships.
- composor:
is a block-oriented CAD graphical simulation tool for system-level
applications. It integrates FIU programs generated by Fide with
nonfuzzy C programs developed by users to build system-level
- run-time code (RTC) generators: The RTC generates the following
1. compact assembly code for Motorola MC6805, MC68HC05, MC68HC08,
MC68HC11, MC68HC16, and 6833X; Intel MCSx96.
2. ANSI C code for PC, Mac, and Unix platforms.
3. MatLab M File format code, to be used as a module of the
MatLab simulator developed by MathWorks, Inc.
4. Java code for the Internet applications.
