21. In 1957, the line was extended along Carey Street to the current loop at Cumberland and Carey Streets. 22. Various Automation Protocols may replace analog current loops , but 4-20 mA is still a principal industrial standard. 23. Unlike the electric dipole, a magnetic dipole is properly modeled as a current loop having a current and an area. 24. In this case the orbiting nucleus functions as an effective current loop , which in turn will generate a magnetic field. 25. The office would have a remote control unit that would operate the taxi company base station over a current loop circuit. 26. Terminals were initially linked to a nearby computer via current loop or serial cables, by conventional analogue voice telephone network. 27. A second advantage of differential TTL, when correctly terminated, is that the differential pair of wires forms a current loop . 28. The valve position and status are fed back over the current loop to the controller, using such as the HART protocol. 29. The connector was for a future RS-232 / 20 mA current loop serial interface, but that was never implemented. 30. The location of the current loop enables a more uniform Lorentz force distribution compared with the aforementioned U-shape cantilever beam.
