At least 90 percent of detector applications should be satisfied by one of the sensors discussed earlier in this chapter. However, when light levels are extremely low, or ambient electronic noise levels are high, or space requirements are particularly limited, other alternatives, such as optical ICs, hybrids, or photomultipliers should be seriously investigated.

The design of fuzzy logic color sensors aims to achieve maximum color sensing ability, while maintaining the expected simplicity of operation and durability of typical discrete industrial sensors. Several other key goals must be considered in system design such as high speed, small size, configurability, high repeatability, and long light source life.

The choice of a solid-state light source satisfies the majority of the criteria for a good industrialized color sensor design. The fuzzy logic color sensor utilizes two sets of three different LED photodiodes as its illumination source. The three LED colors red, green, and blue were chosen essentially for their coverage of the visible light spectrum (Fig. 6.16). The light from each LED is sequentially pulsed onto the target, and its reflected energy is collected by a silicon photoreceiver chip in the LED cluster. Ambient light compensation circuitry is continually refreshed between each LED pulse, so the reported signals are almost entirely due to the LED light pulses. The LED sources offer a very fast (microsecond response) and stable (low spectral drift, steady power) source of a given wavelength band, without resorting to filters. Emerging blue LEDs, in combination with the more common red and green LEDs, have made it possible to use three solid-state spectra to define a hue. The choice of the specific LED bandwidth (or spectral distribution) is made so as to obtain the best color distinction through broader coverage of the illumination spectrum.

Fuzzy Logic Controller Flowcharts
The entire sensor operation is illustrated in Fig. 6.17. An internal microcontroller governs the device operations. It directs signals in and out of the sensor head, to maintain local and remote communications, and provides color discrimination algorithms to produce the appropriate signal output at the control pin. As the device proceeds out of reset, it checks the locally (or remotely) set configuration dipswitches, which in turn define the path, or operating menu, to proceed through. There is permanent storage of learned or remotely loaded values of RGB readings, tolerance, number of readings to

average, and the white-card calibration value, so these settings can be available at reset or at power-up. One or more of three optional menus can be selected before entering into the main operation of learning and running colors. The three alternative menus are (1) white-card gain set, (2) number of reads to average set, and (3) the observed stored reading menus. If none of the alternative menus is activated, the sensor will proceed directly to the primary modes, which are learn, tolerance set,

Sensors Detecting Faults in Dynamic Machine Parts (Bearings)
A system consisting of analog and digital signal processing equipment, computers, and computer programs would detect faults in ball bearings in turbomachines and predict the remaining operating time until failure. The system would operate in real time, extracting the diagnostic and prognostic information from vibrations sensed by accelerometers, strain gauges, and acoustical sensors, and from the speed of the machine as measured by a tachometer. The vibrations that one seeks to identify are those caused by impact that occurs when pits in balls make contact with races and pits in races make contact with balls. These vibrations have patterns that are unique to bearings and repeat at known rates related to ballrotation, ball-pass, and cage-rotation frequencies. These vibrations have a wide spectrum that extends up to hundreds of kilohertz, where the noise component is relatively low. The system in Fig. 6.19 would accept input from one of two sensors. Each input signal would be amplified, bandpass-filtered, and digitized. The digitized signal would be processed in two channels: one to compute the keratosis of the distribution of the amplitudes, the other to calculate the frequency content of the envelope of the signal. The keratosis is the fourth statistical moment and is known, from theory and experiment, to be indicative of vibrations caused by impact on faults. The keratosis would be calculated as a moving average for each consecutive digitized sample of the signal by using a number of samples specified by the technician. The trend of a keratosis moving average would be computed several times per second, and the changes in the keratosis value deemed to be statistically significant would be reported. In the other signal processing channel, the amplitude envelope of the filtered digitized signal would be calculated by squaring the signal. Optionally, the high-frequency sample data would be shifted
