A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
Stack light in automated production for in-line quality inspection. Stack lights (also known as signal tower lights, indicator lights, andon lights, warning lights, industrial signal lights, or tower lights) are commonly used on equipment in industrial manufacturing and process control environments to provide visual and audible indicators of a machine's status to machine operators, technicians ...

The gearbox in a ball valve timer makes a rumbling sound when actuated. The solenoid type switching timers contain a solenoid that relieves pressure on a diaphragm in the water-flow tube or moves a stopper into the water flow area to regulate flow. The solenoid type uses no gears and makes a tapping sound when the solenoid is activated.
The device is simple: a transparent two-liter bottle is filled with water plus a little bleach to inhibit algal growth and fitted into a hole in a roof. The device functions like a deck prism: during daytime the water inside the bottle refracts sunlight, delivering about as much light as a 40–60 watt incandescent bulb to the interior. A ...
Usage includes theatrical lighting, locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights ("cans" in the United States). Many PAR lamps are of the sealed beam variety, with a parabolic reflector , one or more filaments , and a glass or plastic lens sealed permanently together as a unit.
If a change can be implemented by modifying only a few of the layers (typically metal) then the cost is much less than it would be if the design was re-built from scratch. This is because starting the process from the beginning will almost always require new photomasks for all layers, and each of the 20 or so masks in a modern semiconductor ...
At the top, the housing, interrupter disk, and light source can be seen; at the bottom the sensing element and support components. A rotary encoder , also called a shaft encoder , is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals.
