ABSTRACT:
Circuits for detecting faults in variable resistive position feedback sensors common in the use of motion control systems, provide a filter coupled to an output signal of the variable resistive position sensor for processing the signal to detect noise indicative of intermittent faults. A memory stores occurrences of signals from the filter. The memory can activate an alarm which indicates that a failure is detected. The circuits are particularly applicable to medical imaging systems such as SPECT, PET or MRI systems which contain a multiplicity of moving components that require accurate motion control and positioning.
