Camera stabilizer operator Garrett Brown invented the Steadicam, a body-mounted stabilization apparatus for motion picture cameras, which uses springs as shock absorbers. In 1991, Martin Philip Stevens (born in England in 1963) invented a hand-held camera stabilizer for motion-picture and video cameras, called the "Glidecam". Some camera stabilization machines use gyroscopes to sense disruptive motion. The Artemis Trinity system from Arri combines a mechanical and electronic stabilization. Although a tripod can hold a camera stably, stationary platforms are not regarded as camera stabilizers. A camera shoulder brace stabilizes by shifting the weight of the camera to the operator's shoulder. This allows for
