1. A failure sensing and control system for a cycle test station, comprising:
- a sensor configured to sense motion of a part being cycle tested and generate a signal indicating a completion of a first motion cycle and a second motion cycle; and
a controller configured to;
receive the signal from the sensor,measure an elapsed amount of time from a beginning of the second motion cycle based on the signal,determine that a test failure has occurred when the elapsed amount of time from the beginning of the second motion cycle reaches a predetermined amount of time before the completion of the second motion cycle, andstop the cycle test station when the test failure has occurred.

Abstract
A sensing and control system terminates a cycle test when it senses the part being cycle tested is about to fail. The sensing and control system uses a sensor for generating a signal each time the test part completes a motion cycle. The sensing and control system uses a controller, responsive to the sensor, for determining whether a failure is about to occur and stopping the cycle test.

12. A system for controlling a cycle test station cycling a part, comprising:
-
a sensor configured to sense motion of the part and generate a pulse signal having a plurality of pulses, each of the plurality of pulses indicating completion of each of a plurality of motion cycles; a timer responsive to the generated pulse signal and configured to reset each time one of the plurality of pulse signals is received and measure an elapsed amount of time for each of the plurality of motion cycles; a controller coupled to the timer and configured to generate a termination signal indicating a test failure in response to the elapsed amount of time of one of the plurality of motion cycles reaching a predetermined amount of time before the pulse corresponding to the completion of the one of the plurality of motion cycles is generated; and a switch configured to terminate power to the cycle test station in response to the termination signal. - View Dependent Claims (13, 14, 15)

16. A method for sensing failure and controlling a cycle test station, comprising the steps of:
-
generating, at a sensor, a signal based on motion of a part being cycle tested by a cycle test station, the signal indicating a completion of a first motion cycle and a second motion cycle; measuring, using a timer, an elapsed amount of time from a beginning of the second motion cycle based on the signal; determining, by a controller, that a test failure has occurred when the elapsed amount of time from the beginning of the second motion cycle reaches a predetermined amount of time before the completion of the second motion cycle; and causing, using the controller, the cycle test station to stop in response to the occurrence of the test failure. - View Dependent Claims (17, 18, 19)
