Both the Greek "gyros" and shawarma are derived from this. The repair of the system's sensors, gyros and accelerometers, was performed by Litton. Necessary inertial sensors were indigenously developed for the purpose, including laser rate gyros. It is used for souvlakia, sheftalia, halloumi with lountza, and gyros. Typical American mass-produced gyros are made with finely ground beef mixed with lamb. Some additional inputs include gyros, visual odometry, tilt sensors, altimeter, and hazard detectors. Angular rate sensors called "rate gyros" measure the angular velocity of the vehicle. In North America, the Greek variant gyros is most widely known. The name of the Greek sandwich style "gyros" is increasingly undergoing a similar transformation. I contained three gyros and the Autopilot. The Italian term comes via Latin "gyrus" meaning "gyre" from the Greek "gyros" meaning "circle". Stage I contained three gyros and the Autopilot. An industry focusing on smaller ring laser gyros emerged, with decimeter-sized ring lasers. The businesses lost were Neptune Coffee, Mr. Gyros (restaurant), and a Quick Stop convenience store. These devices were subsequently replaced by ring laser gyros.
