(Redirected from Ring transporter)
Circular rings about half the size of the Stargate, which function on the same principles. When in position the rings transmit all matter within their circular formation to another pair of rings at a different location, utilizing a conduit of bright energy. If there is a person or object on the receiving end, the rings can exchange the two simultaneously.
It is possible to intercept this energy field by moving a mobile set of transport rings (on board a ship) into the correct position along the matter stream. Ships equipped with rings are capable of detecting the location of receiving rings on a planet's surface, or on board another ship.
Rings are activated by a transport rings remote, or by a stationary control panel built into a ship or facility. Rings generally require a sending and receiving ring platform to operate, though a ship's rings can be used to send and retrieve matter located immediately below it, within the range of the physical ring mechanism. The platforms have been placed by the Goa'uld on most ships, as well as in structures and buried on the surfaces of planets.
