  2. Dielectric resonator - Wikipedia

    en.wikipedia.org/wiki/Dielectric_resonator

    Dielectric resonators' main use is in millimeter-wave electronic oscillators (dielectric resonator oscillator, DRO) to control the frequency of the radio waves generated. They are also used as bandpass filters as well as antennas .

  3. Digital read out - Wikipedia

    en.wikipedia.org/wiki/Digital_read_out

    In machine-shop terminology, the complete digital read-out system (consisting of a computer, axis-position encoders, and a numeric display) is referred to by the acronym DRO. Such a system is commonly fitted to machines in today's shops, especially for metal working — lathes, cylindrical grinders, milling machines, surface grinders, boring ...

    An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.

  6. Fleming's right-hand rule - Wikipedia

    en.wikipedia.org/wiki/Fleming's_right-hand_rule

    The right hand is held with the thumb, index finger and middle finger mutually perpendicular to each other (at right angles), as shown in the diagram. [1] The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field. The first finger is pointed in the direction of the magnetic field. By convention, it's ...

  7. Dry sump - Wikipedia

    en.wikipedia.org/wiki/Dry_sump

    Increased engine power. In a wet-sump engine, oil slosh against spinning parts causes substantial viscous drag which creates parasitic power loss. [5] [6] A dry-sump system removes oil from the crankcase, along with the possibility of such viscous drag. More complex dry-sump systems may scavenge oil from other areas where oil may pool, such as ...

  8. Walsh diagram - Wikipedia

    en.wikipedia.org/wiki/Walsh_diagram

    Walsh diagrams in conjunction with molecular orbital theory can also be used as a tool to predict reactivity. By generating a Walsh Diagram and then determining the HOMO/LUMO of that molecule, it can be determined how the molecule is likely to react. In the following example, the Lewis acidity of AH 3 molecules such as BH 3 and CH 3 + is predicted.
