Power over Ethernet (PoE) describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points (WAPs), IP cameras and VoIP phones .
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 .
Power-over-fiber, or PoF, is a technology in which a fiber-optic cable carries optical power, which is used as an energy source rather than, or as well as, carrying data. [1] [2] [3] This allows a device to be remotely powered, while providing electrical isolation between the device and the power supply.
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.
The current injection technique examined in Dr Eio's publications optimize the switching transient of power diodes, thyristors and insulated gate bipolar transistors (IGBTs) without the need of changing the structure of these devices.
A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and cooled by the fuel itself.
MRO is one of six regional entities under North American Electric Reliability Corporation (NERC) authority. NERC and the regional reliability councils were formed following the Northeast Blackout of 1965. MRO's offices are located in St. Paul, Minnesota. MRO members include municipal utilities, cooperatives, investor-owned utilities, a federal ...
Certain multi-point injection systems also use tubes with poppet valves fed by a central injector instead of individual injectors. Typically though, a multi-point injected engine has one fuel injector per cylinder, an electric fuel pump, a fuel distributor, an airflow sensor, [ 5 ] and, in modern engines, an engine control unit .
