Abstract: An angle shift compensation system and method for controlling a sinusoidally driven motor to achieve efficient motion and reduced noise. The motor controller uses the angle shift compensation method to monitor the angle shift between a sinusoidal motor control signal configured to drive the motor and a feedback signal received from at least one position detector indicating the position of the motor rotor with respect to the motor stator. In response, the motor controller proportionally adjusts the amplitude of the motor control signal based on the monitored angle shift to maintain the angle shift substantially equal to an angle shift threshold.

Abstract: A failure detection device is disclosed. The failure detection device may receive operations data related to operations of a set of parts of a machine. The failure detection device may process the operations data using a condition-based processing technique. The condition-based processing technique may be associated with mapping initial values of data elements of the operations data to binary values based on satisfaction of a first set of conditions by the initial values. The failure detection device may detect a presence of a possible issue with the operations of the set of parts based on a second set of conditions, associated with the binary values and the initial values, being satisfied during a time period. The failure detection device may perform, after detecting the presence of the possible issue, a set of actions related to addressing the possible issue.
