Assignee: nan
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A system for detecting backlash in a device comprising:
a controller;
an actuator, wherein the controller measures, records and stores a movement information signal from the actuator;
an actuator output element;
at least one feedback device that measures, records, and stores movement information of the actuator input element; and
at least one movement sensor for detecting movement information of the actuator output element;
wherein the system is configured to:
determine a calibration movement ratio for a device with respect to at least two parts in the device;
collect baseline motion values for the at least two parts in the device during use;
measure baseline motion values for the at least two parts in the device during use;
collect active motion values for the at least two parts in the device;
measure active motion values for the at least two parts in the device;
compare the measured baseline motion values to the active motion values;
compute a ratio of variance between the measured baseline motion values and the active motion values; and
compare the calculated ratio of variance to the calibration movement ratio.
