  2. Decoupling capacitor - Wikipedia

    en.wikipedia.org/wiki/Decoupling_capacitor

    A bypass capacitor is often used to decouple a subcircuit from AC signals or voltage spikes on a power supply or other line. A bypass capacitor can shunt energy from those signals, or transients, past the subcircuit to be decoupled, right to the return path. For a power supply line, a bypass capacitor from the supply voltage line to the power ...

  3. Pump drill - Wikipedia

    en.wikipedia.org/wiki/Pump_drill

    A pump drill is a simple hand-powered device used to impart a rapid rotating motion to a rod (the spindle or drill shaft). It can be used for fire making or as a drill to make holes in various materials. [1] It consists of: the drill shaft, a narrow board with a hole through the center, a weight (usually a heavy disc) acting as a flywheel, and ...

  4. Quint (fire apparatus) - Wikipedia

    en.wikipedia.org/wiki/Quint_(fire_apparatus)

    A quintuple combination pumper or quint is a fire-fighting apparatus that serves the dual purpose of an engine and a ladder truck. “Quintuple” refers to the five functions that a quint provides: pump, water tank, fire hose, aerial device, and ground ladders. [1] Tillers and tractor-drawn aerials also have quint features, and are dubbed ...

  5. Fire drill (tool) - Wikipedia

    en.wikipedia.org/wiki/Fire_drill_(tool)

    A fire drill, sometimes called fire-stick, is a device to start a fire by friction between a rapidly rotating wooden rod (the spindle or shaft) and a cavity on a stationary wood piece (the hearth or fireboard).

  6. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    Pressure regulator for domestic water supply. Outlet pressure is set with the blue handwheel and shown on the vertical scale. A water pressure regulating valve limits inflow by dynamically changing the valve opening so that when less pressure is on the outside, the valve opens up fully, and too much pressure on the outside causes the valve to shut.

  8. Flyback diode - Wikipedia

    en.wikipedia.org/wiki/Flyback_diode

    A switched-mode power supply also exploits this effect, but the energy is not dissipated to heat and is instead used to pump a packet of additional charge into a capacitor, in order to supply power to a load. When the inductive load is a relay, the flyback diode can noticeably delay the release of the relay by keeping the coil current flowing ...
