  2. Relay logic - Wikipedia

    en.wikipedia.org/wiki/Relay_logic

    There are also pocket sized printers that print onto an adhesive backed label that can be wrapped around the wire. The basic format for relay logic diagrams is as follows: 1. The two vertical lines that connect all devices on the relay logic diagram are labeled L1 and L2. The space between L1 and L2 represents the voltage of the control circuit. 2.

    en.wikipedia.org/wiki/Elevator_(aeronautics)

    Elevators' effect on pitch Elevator and pitch trim tab of a light aircraft. Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer.

    The Electronics Project has a list of desirable features for a circuit drawing program. This table attempts to summarize which of the features each of the above programs has. The "Easy circuits" column is specifically answering the question: "Is it easy to use this program to draw circuit layouts?"

  5. Ladder logic - Wikipedia

    en.wikipedia.org/wiki/Ladder_logic

    Part of a ladder diagram, including contacts and coils, compares, timers and monostable multivibrators. Ladder logic is widely used to program PLCs, where sequential control of a process or manufacturing operation is required. Ladder logic is useful for simple but critical control systems or for reworking old hardwired relay circuits. As ...

    A blueprint is the drawing of the technical design and final product. After all, this is done, and you use the blueprint to put the circuit together, you will get the results of electrical circuits that are quite memorable. The circuit will run anything from a vacuum to a big TV in a movie theater.

  9. Elevator algorithm - Wikipedia

    en.wikipedia.org/wiki/Elevator_algorithm

    The elevator algorithm, or SCAN, is a disk-scheduling algorithm to determine the motion of the disk's arm and head in servicing read and write requests.. This algorithm is named after the behavior of a building elevator, where the elevator continues to travel in its current direction (up or down) until empty, stopping only to let individuals off or to pick up new individuals heading in the ...
