  2. Power over Ethernet - Wikipedia

    en.wikipedia.org/wiki/Power_over_Ethernet

    The splitter is the silver and black box in the middle between the wiring junction box (left) and the access point (right). The PoE connection eliminates the need for a nearby power outlet . In another common configuration, the access point or other connected device includes internal PoE splitting and the external splitter is not necessary.

  3. Multi-port power electronic interface - Wikipedia

    en.wikipedia.org/wiki/Multi-port_power...

    Within the electronics industry, a Multi-port Power Electronic Interface (MPEI) is a self-sustainable multiple input/output static power electronic converter. It is capable of interfacing with different sources, storages, and loads.

  4. Electronically controlled unit injector - Wikipedia

    en.wikipedia.org/wiki/Electronically_controlled...

    An electronically controlled unit injector (EUI) sometimes referred to as a mechanical electronic unit injector (MEUI) is a unit injector (UI) with electronic control. It performs the same function as a conventional unit injector in an internal combustion engine , such as in an on-road or off-road vehicle or a diesel-electric locomotive .

  5. Port (circuit theory) - Wikipedia

    en.wikipedia.org/wiki/Port_(circuit_theory)

    In electrical circuit theory, a port is a pair of terminals connecting an electrical network or circuit to an external circuit, as a point of entry or exit for electrical energy. A port consists of two nodes (terminals) connected to an outside circuit which meets the port condition – the currents flowing into the two nodes must be equal and ...

  6. Super I/O - Wikipedia

    en.wikipedia.org/wiki/Super_I/O

    Super I/O (sometimes Multi-IO) [1] is a class of I/O controller integrated circuits that began to be used on personal computer motherboards in the late 1980s, originally as add-in cards, later embedded on the motherboards. A super I/O chip combines interfaces for a variety of low-bandwidth devices.

  7. Integrated injection logic - Wikipedia

    en.wikipedia.org/wiki/Integrated_injection_logic

    Integrated injection logic (IIL, I 2 L, or I2L) is a class of digital circuits built with multiple collector bipolar junction transistors (BJT). [1] When introduced it had speed comparable to TTL yet was almost as low power as CMOS , making it ideal for use in VLSI (and larger) integrated circuits .

  8. Reciprocity (electrical networks) - Wikipedia

    en.wikipedia.org/wiki/Reciprocity_(electrical...

    If a current, , injected into port A produces a voltage, , at port B and injected into port B produces at port A, then the network is said to be reciprocal. Equivalently, reciprocity can be defined by the dual situation; applying voltage, , at port A producing current at port B and at port B producing current at port A. [1] In general, passive networks are reciprocal.

  9. Bias tee - Wikipedia

    en.wikipedia.org/wiki/Bias_tee

    A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.
