Patent number: 8988175
Abstract: An override device is described for use with a coupler of a circuit breaker. The override device comprising a cam member coupled to the coupler. The cam member comprising a slot. The override device also including an actuator coupled to the cam member and configured to move the cam member between an over-current protection position and an over-current relay override position and a push member coupled to the coupler. The slot configured to guide the push member to a first position when the actuator moves the cam member to the over-current protection position. The slot further configured to guide the push member to a second position when the actuator moves the cam member to the over-current relay override position to permit current flow through the circuit breaker.

Patent number: 8988016
Abstract: A control method comprises determining wheel creep of a wheel operably coupled to a traction motor and limiting a rate of change of an excitation frequency applied to the traction motor to drive the wheel, based on the determined wheel creep. According to one aspect, the rate of change of the excitation frequency is limited if the wheel creep exceeds a wheel creep threshold.
