The bottom half of the ring is three-quarter wavelengths in length. The ring has a characteristic impedance of factor compared to port impedance. A signal input on port 1 will be split between ports 2 and 4, and port 3 will be isolated. The full scattering matrix for an ideal 3 dB rat-race is
Wiring is an open-source electronics prototyping platform composed of a programming language, an integrated development environment (IDE), and a single-board microcontroller. It was developed starting in 2003 by Hernando Barragán .
The ring starts at the consumer unit (also known as fuse box, distribution board, or breaker box), visits each socket in turn, and then returns to the consumer unit. The ring is fed from a fuse or circuit breaker in the consumer unit. Ring circuits are commonly used in British wiring with socket-outlets taking fused plugs to BS 1363. Because ...
The voltage at a subscriber's network interface is typically 48 V between the ring and tip wires, with tip near ground (slightly negative relative to ground) and ring at −48 V relative to tip. In the middle 20th century, long loops in many rural areas of North America used range extenders, which operated at 100 or 130 volts to ensure reliable ...

Starter ring gear attached to a flywheel. In cars with a manual transmission, the starter ring gear is fitted to the outer diameter of the flywheel.The ring gear is usually fixed to the flywheel through use of an interference fit, [2] which is achieved by heating the ring gear and so that thermal expansion allows it to be placed around the flywheel.
Wire binding is a popular commercial book binding method, and is known by various names, including double loop wire, double-o, ring wire, twin loop wire, wire comb, wire-o, wirebind and wiro. With this binding method, users insert their punched pages onto a C-shaped spine , and then use a wire closer to squeeze the spine until it is round. [ 1 ]
When a hierarchy of modes exists (ring-based security), faults and exceptions at one privilege level may destabilize only the higher-numbered privilege levels. Thus, a fault in Ring 0 (the kernel mode with the highest privilege) will crash the entire system, but a fault in Ring 2 will only affect Rings 3 and beyond and Ring 2 itself, at most.
