  2. Hormonal intrauterine device - Wikipedia

    en.wikipedia.org/wiki/Hormonal_intrauterine_device

    It is one of the most effective forms of birth control with a one-year failure rate around 0.2%. [1] The device is placed in the uterus and lasts three to eight years. [3] [4] Fertility often returns quickly following removal. [2] Side effects include irregular periods, benign ovarian cysts, pelvic pain, and depression. [2]

  3. Transmission control unit - Wikipedia

    en.wikipedia.org/wiki/Transmission_Control_Unit

    A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.

  4. Current loop - Wikipedia

    en.wikipedia.org/wiki/Current_loop

    A major application of current loops is the industry de facto standard 4–20 mA current loop for process control applications, where they are extensively used to carry signals from process instrumentation to proportional–integral–derivative (PID) controllers, supervisory control and data acquisition (SCADA) systems, and programmable logic ...

  5. Four-wire circuit - Wikipedia

    en.wikipedia.org/wiki/Four-wire_circuit

    In telecommunications, a four-wire circuit is a two-way circuit using two paths so arranged that the respective signals are transmitted in one direction only by one path and in the other direction by the other path. The four-wire circuit gets its name from the fact that is uses four conductors to create two complete electrical circuits, one for ...

    en.wikipedia.org/wiki/Closed-loop_transfer_function

    An example of a closed-loop block diagram, from which a transfer function may be computed, is shown below: The summing node and the G(s) and H(s) blocks can all be combined into one block, which would have the following transfer function: () = + ()

  7. Teletouch - Wikipedia

    en.wikipedia.org/wiki/Teletouch

    Pushing a button on the shift control preselected the chosen gear. The electrical circuit was closed only after the driver fully depressed the clutch pedal. This energized the appropriate transmission mounted solenoids necessary for returning the transmission to neutral and then completing engagement of the preselected gear.

  8. Quarter-wave impedance transformer - Wikipedia

    en.wikipedia.org/wiki/Quarter-wave_impedance...

    Standing waves on a transmission line with an open-circuit load (top), and a short-circuit load (bottom). Black dots represent electrons, and arrows show the electric field. A quarter-wavelength away from the open-circuit, the current and voltage oscillations are exactly the same as at a short-circuit, and vice versa.

  9. Relay logic - Wikipedia

    en.wikipedia.org/wiki/Relay_logic

    Example Ladder Logic Diagram. The schematic diagrams for relay logic circuits are often called line diagrams, because the inputs and outputs are essentially drawn in a series of lines. A relay logic circuit is an electrical network consisting of lines, or rungs, in which each line or rung must have continuity to enable the output device. A ...
