  2. Power over Ethernet - Wikipedia

    en.wikipedia.org/wiki/Power_over_Ethernet

    In a passive PoE system, the injector does not communicate with the powered device to negotiate its voltage or wattage requirements, but merely supplies power at all times. Common 100 Mbit/s passive applications use the pinout of 802.3af mode B (see § Pinouts ) – with DC positive on pins 4 and 5 and DC negative on 7 and 8 and data on 1–2 ...

  3. Multi-port power electronic interface - Wikipedia

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

    It is capable of interfacing with different sources, storages, and loads. The integrated control system of MPEI enables excellent dynamic and steady state performance, which renders optimal renewable energy harvesting, optimal energy management, and optimal and economical utility grid interactions in a deregulated power market.

  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. Power management integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Power_management...

    Power management ICs are solid state devices that control the flow and direction of electrical power. Many electrical devices use multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power (e.g., wall outlet, battery, etc.), meaning that the power design of the device has multiple requirements for operation. A PMIC ...

  6. 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. The gates can be made smaller with this logic ...

  7. MegaSquirt - Wikipedia

    en.wikipedia.org/wiki/MegaSquirt

    The code has (multiple) 12x12 fuel and spark tables, stepper IAC control, PWM idle valve control, several user-configurable spare ports (for things like boost control, water injection, fan control, etc.), self-tuning functions (Automatic Mixture Control - AMC), and fuel control to 1 μs (100 times more resolution than MegaSquirt-I).
