  2. Duplex (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Duplex_(telecommunications)

    A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...

  3. Two-way radio - Wikipedia

    en.wikipedia.org/wiki/Two-way_radio

    Naval air traffic controller communicates with aircraft over a two-way radio headset A variety of portable handheld two-way radios for private use. A two-way radio is a radio transceiver (a radio that can both transmit and receive radio waves), which is used for bidirectional person-to-person voice communication with other users with similar radios, [1] in contrast to a broadcast receiver ...

  4. Wavelength-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Wavelength-division...

    Since communication over a single wavelength is one-way (simplex communication), and most practical communication systems require two-way (duplex communication) communication, two wavelengths will be required if on the same fiber; if separate fibers are used in a so-called fiber pair, then the same wavelength is normally used and it is not WDM ...

  5. Talk:Simplex communication - Wikipedia

    en.wikipedia.org/wiki/Talk:Simplex_communication

    The only area of confusion is thus the use of the word duplex vs full-duplex. There is no actual conflict. 81.105.8.110 11:00, 16 December 2009 (UTC) I agree with 81.105.8.110 and Bigpeteb. I found many reliable sources online defining these terms and almost all of them define "simplex" as one-way communication, not one direction at a time.

    en.wikipedia.org/wiki/Destination_dispatch

    A destination dispatch elevator, here using a Compass system from Otis.. Destination dispatch is an optimization technique used for multi-elevator installations, in which groups of passengers heading to the same destinations use the same elevators, thereby reducing waiting and travel times.

  7. SimplexGrinnell - Wikipedia

    en.wikipedia.org/wiki/SimplexGrinnell

    Simplex's time-division began to lose market share, but their newly founded fire alarm division significantly prospered. In 1970, Simplex introduced conventional control panels . In 1979, Simplex introduced the industry's first networked multiplex building control system that was capable of handling fire alarm, security, HVAC, synchronized time ...

  8. Elevator algorithm - Wikipedia

    en.wikipedia.org/wiki/Elevator_algorithm

    The elevator algorithm, or SCAN, is a disk-scheduling algorithm to determine the motion of the disk's arm and head in servicing read and write requests.. This algorithm is named after the behavior of a building elevator, where the elevator continues to travel in its current direction (up or down) until empty, stopping only to let individuals off or to pick up new individuals heading in the ...

  9. Elevator operator - Wikipedia

    en.wikipedia.org/wiki/Elevator_operator

    The elevator operator had to regulate the elevator's speed, which typically required a good sense of timing to consistently stop the elevator level with each floor. In addition to their training in operation and safety, department stores later combined the role of operator with greeter and tour guide , announcing product departments, floor by ...
