Abstract: A protection feature is disclosed for a self powered protection relay having, for example, sensitive earth fault protection. Protection can be achieved in tandem with optimal power on trip time and with integrated logic for inrush discrimination. The self supplied protection relay can include a current processing module to measure and evaluate line current to generate a trip signal, and to suppress inrush current to block earth fault detection during an inrush condition and thereby increase sensitivity of fault detection.

Abstract: An industrial robot includes first and second kinematic chains configured to transmit the movements of corresponding first and second actuators to respective movements of an end effector. The first kinematic chain includes a first rod which is stiff. The second kinematic chain includes elements between the second actuator and the first rod such that the actuation of the second actuator causes bending forces on the first rod. The first and second kinematic chains thereby have the first rod as a common element, which improves compactness and accessibility of the robot. This improvement assumes that the robot is provided with one or more stiff rods that can bear the bending forces resulting from the actuation of the corresponding actuators.
