Port 1 is the input port where power is applied. Port 3 is the coupled port where a portion of the power applied to port 1 appears. Port 2 is the transmitted port where the power from port 1 is outputted, less the portion that went to port 3. Directional couplers are frequently symmetrical so there also exists port 4, the isolated port.
If the arms for port 2 and 3 are connected with un-equal impedances, then asymmetric division of power can be achieved. When characteristic impedance is Z 0 {\displaystyle Z_{0}} , and one wants to split power as P 2 {\displaystyle P_{2}} and P 3 {\displaystyle P_{3}} , and P 2 {\displaystyle P_{2}} ≠ P 3 {\displaystyle P_{3}} , then the ...
Tampa Bay is the birthplace of commercial airline service, when pioneer aviator Tony Jannus flew the inaugural flight of the St. Petersburg-Tampa Airboat Line on January 1, 1914, from St. Petersburg, to Tampa using a Benoist Flying Boat—the first scheduled commercial airline flight in the world using a heavier-than-air airplane.
The most well-known is the system of normal, alternate, direct laws and mechanical alternate control laws of the Airbus A320-A380. [3] The other is Boeing's fly-by-wire system, used in the Boeing 777, Boeing 787 Dreamliner and Boeing 747-8. [4] [6]
Flight paths of aircraft departing Hollywood Burbank Airport changed as part of the Federal Aviation Administration's airspace modernization program called NextGen.An independent analysis confirmed in October 2018 that "a connection was found between the [NextGen] implementation and the increase in the number of flights over areas south of the 101 Freeway.".
Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. The earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire ) to act as a ...

The eBUS 2-wire interface is an asynchronous serial port with active-low voltage that exchanges 8-bit bytes with start and (single) stop bits (no parity bit), at a symbol rate of 2400 baud, and can be implemented with a standard UART plus a voltage converter.
