摘要: In a circular scanning pattern tracing system, a dual scanning pattern is provided to detect pattern changes in advance of the system steering axis. Pattern detection pulses from both the scanning patterns are adjustable in length and the overlap of the pulses is used to determine whether the system should slow down.

摘要: In a circular scanning pattern tracing system having a sample and hold circuit, the width of the sample pulse is - made adjustable. This variable width is equivalent to a variable low pass filter in the system. The effective cut off frequency of the filter is made dependent on the system tangential tracing velocity.
