  2. SY control cable - Wikipedia

    en.wikipedia.org/wiki/SY_control_cable

    SY control cables are not suitable for fixed wiring applications in the UK requiring compliance with the requirements set out in BS 7671. [4] SY cable should not be used in areas exposed to ultraviolet light as it damages the outer sheath leading to cracking and then rusting of the braid as water penetrates the damaged sheath.

  3. Image registration - Wikipedia

    en.wikipedia.org/wiki/Image_registration

    Image registration or image alignment algorithms can be classified into intensity-based and feature-based. [3] One of the images is referred to as the moving or source and the others are referred to as the target, fixed or sensed images. Image registration involves spatially transforming the source/moving image(s) to align with the target image.

  4. Electrical wiring in North America - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring_in_North...

    Electrical wiring practices developed in parallel in many countries in the late 19th and early 20th centuries. [7] As a result, national and regional variations developed and remain in effect. (see National Electrical Code, electrical wiring, electrical wiring in the United Kingdom). Some of these are retained for technical reasons, since the ...

  5. Local Interconnect Network - Wikipedia

    en.wikipedia.org/wiki/Local_Interconnect_Network

    LIN slaves running on RC oscillator will use the distance between a fixed amount of rising and falling edges to measure the current bit time on the bus (the master's time normal) and to recalculate the internal baud rate. INTER BYTE SPACE: Inter Byte Space is used to adjust for bus jitter. It is an optional component within the LIN specification.

  6. Twin-lead - Wikipedia

    en.wikipedia.org/wiki/Twin-lead

    The wires are held a fixed distance apart by a plastic ribbon that is a good insulator at radio frequencies (usually polyethylene). It is also called (two wire) ribbon cable. The uniform spacing of the wires is the key to the cable's function as a transmission line: Any abrupt change in spacing would cause some of the signal to reflect back ...

  7. BS 7671 - Wikipedia

    en.wikipedia.org/wiki/BS_7671

    for AC having a supply frequency of 50, 60 or 400Hz, though the use of other frequencies for special purposes is not excluded. This includes low-voltage installations, as found in most domestic and commercial properties, and extra-low-voltage systems, but excludes high voltage , as found in generation, transmission and distribution networks.

  8. Characteristic impedance - Wikipedia

    en.wikipedia.org/wiki/Characteristic_impedance

    The characteristic impedance () of an infinite transmission line at a given angular frequency is the ratio of the voltage and current of a pure sinusoidal wave of the same frequency travelling along the line. This relation is also the case for finite transmission lines until the wave reaches the end of the line.
