  3. 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 ...

    The amount of data is fixed by the application designer and mirrors data relevant for the application which the LIN slave runs in. CHECKSUM: There are two checksum-models available within LIN - The first is the checksum including the data bytes only (specification up to Version 1.3), the second one includes the identifier in addition (Version 2 ...

    The position/object/item packets contain the latitude and longitude, and a symbol to be displayed on the map, and have many optional fields for altitude, course, speed, radiated power, antenna height above average terrain, antenna gain, and voice operating frequency. Positions of fixed stations are configured in the APRS software.

    When the user clicks the "Upload to Wiring hardware" button in the IDE, a copy of the code is written to a temporary file including a standard header file at the file beginning, and a simple main function appended. The Wiring IDE uses the GNU toolchain and AVR Libc to compile programs, and uses avrdude to upload programs to the board.

  7. SENT (protocol) - Wikipedia

    en.wikipedia.org/wiki/SENT_(protocol)

    After the calibration pulse, each nibble is transmitted with a fixed-width low signal, followed by a variable-length high period. The low pulse-width is 5 (or more) ticks in length, while the high pulse-width can vary, for a total period between falling edges of between 12-27 ticks (representing nibbles ranging from 0-15).

    en.wikipedia.org/wiki/Fixed_wireless

    Fixed wireless is the operation of wireless communication devices or systems used to connect two fixed locations (e.g., building to building or tower to building) with a radio or other wireless link, such as laser bridge. [1] Usually, fixed wireless is part of a wireless LAN infrastructure. The purpose of a fixed wireless link is to enable data ...

  9. Propagation delay - Wikipedia

    en.wikipedia.org/wiki/Propagation_delay

    Propagation delay is equal to d / s where d is the distance and s is the wave propagation speed. In wireless communication, s=c, i.e. the speed of light. In copper wire, the speed s generally ranges from .59c to .77c. [3] [4] This delay is the major obstacle in the development of high-speed computers and is called the interconnect bottleneck in ...
