Analog Encoding -  Convert switches and sensors into DMX signals. Uses are found in Haunted houses, stage plays, med events, holiday light animations, anytime you want to control DMX compatible equipment. Fog machines and strobe lights can be indecently controlled be remote switches or sensors. (added 02/05)
Analog switch lowers relay power consumption -  20-Dec-01 Issue of EDN  Designers often use relays as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. However, the power dissipation in a relay coil may render the device unattractive in battery-powered applications. You can lower this dissipation by adding an analog switch that allows the relay to operate at a lower voltage (Figure 1].... [Design Idea by Steve Caldwell, Maxim Integrated Products, Chandler, AZ]
AND gate lets sleeping Controllers lie -  05/23/96 EDN-Design Ideas  Battery-operated portable equipment often makes use of  80L51 µP's power-down mode to conserve battery energy. CMOS-memory contents are critical in many of se systems, so  system must sustain  CMOS-memory-supply voltage without interruption and for as long as possible.  In Figure 1, a µP supervisor (IC1]guards  µP (IC3]against....
