92. Position detectors provide motor-control logic
    Steve Pomeroy Russell Hedges
    Circuits Fairchild H21B1
    In the circuit of Figure 1, assume that a brush-type dc motor must drive a load back and forth between two endpoints on a lead screw. Optical sensors determine end of travel, and an SPDT switch selects to which end to send the load. The sensors ...

98. Two transistors form high-precision, ac-mains ZCD
    Circuits Fairchild BC549B
    Many applications that use 110 V/230 V-ac mains require a ZCD (zero-crossing-detection) circuit for the ac-line voltage, for example, to synchronize the switching of loads. One method of ZCD uses a high-value current-limiting resistor or a ...

100. Circuit controls intensity of reflex optical sights
     Stephen Woodward
     Circuits Fairchild L14Q1
     A popular category of aiming/pointing aids is the reflex, or “red-dot,” sight. This system finds use in such diverse applications as astronomy, archery, and shooting. In the reflex sight, light from an internal source typically a ...
