Introduced: September 1968
Description
G01P covers instruments and methods for measuring kinematic quantities including linear and angular velocity, acceleration, deceleration, and shock or impact forces. The subclass encompasses accelerometers, speedometers, tachometers, gyroscopes, and motion detection devices across mechanical, electrical, electromagnetic, and optical measurement principles. It also includes devices that indicate whether motion is occurring or absent, and systems that determine the direction of movement, with applications ranging from automotive and aerospace to seismic monitoring and consumer electronics.
