  2. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

    en.wikipedia.org/wiki/Video_display_controller

    Block diagram of a NEC μPD7220 graphics display controller. A video display controller (VDC), also called a display engine or display interface, is an integrated circuit which is the main component in a video-signal generator, a device responsible for the production of a TV video signal in a computing or game system.

  4. NTSC - Wikipedia

    en.wikipedia.org/wiki/NTSC

    The use of NTSC coded color in S-Video systems, as well as the use of closed-circuit composite NTSC, both eliminate the phase distortions because there is no reception ghosting in a closed-circuit system to smear the color burst. For VHS videotape on the horizontal axis and frame rate of the three color systems when used with this scheme, the ...

    Angie's List and NBC Bay Area both highlighted an October 2002 ruling in a New Jersey Superior Court, which found that FPE (Federal Pacific Electric), the manufacturer of the Stab-Lok breakers and panels, "knowingly and purposefully [sic] distributed circuit breakers which were not tested to meet UL standards as indicated on their label".

  6. Television standards conversion - Wikipedia

    en.wikipedia.org/wiki/Television_standards...

    For viewing native PAL or SECAM material (such as European television series and some European movies) on NTSC equipment, a standards conversion has to take place. There are basically two ways to accomplish this: The framerate can be slowed from 25 to 23.976 frames per second (a slowdown of about 4%) to subsequently apply 3:2 pulldown .

  7. Distribution board - Wikipedia

    en.wikipedia.org/wiki/Distribution_board

    A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

  8. Vectorscope - Wikipedia

    en.wikipedia.org/wiki/Vectorscope

    NTSC vectorscopes have one set of boxes for the color bars, while their PAL counterparts have two sets of boxes, because the R-Y chrominance component in PAL reverses in phase on alternating lines. Another element in the graticule is a fine grid at 270° on the display (i.e. the -U position) used for measuring differential gain and phase .

    Three single-phase Soviet/Russian 110-kV oil circuit breakers 400 kV SF 6 live-tank circuit breakers Electrical power transmission networks are protected and controlled by high-voltage breakers. The definition of high voltage varies but in power transmission work is usually thought to be 72.5 kV or higher, according to a recent definition by ...
