ABSTRACT:
A mechanical actuator assembly which automatically releases the load controlled by the actuator when the actuator jams or otherwise fails. The actuator assembly has two kinetic energy sources, the outputs of which are normally summed for application to the load. A monitoring device monitors the two kinetic energy outputs. When the relationship between those outputs deviates substantially from a predetermined relationship, the load is disconnected from the actuator assembly.
