The present invention relates to an automatic control device for a padlock which enables automatic control of the padlock connected to a circuit breaker installed in a distribution board of semiconductor or LCD equipment. In the present invention, a pair of cylinders, which can supply and cut off electric power to and from a load terminal, is directly installed on top of the circuit breaker installed in the distribution board, so that a switch of the circuit breaker is turned on/off as the pair of cylinders selectively operates according to an external control signal. As a result, it is unnecessary to separately install the padlock for switching on/off the circuit breaker.

A method for detecting insufficient contact pressure between two contacts of an electrical switching unit, including a device for resetting a mechanism for controlling the switching unit following a closure maneuver of the mechanism, the resetting device including a motor configured to complete the closure maneuver of the control mechanism. The method involves detecting whether the motor completes the closure and whether a resetting torque corresponds to a normal resetting torque, by analyzing an envelope curve of current consumed by the motor over time, and, if the motor completes the closure, deducing that a wear is a result of wear in the mechanism or a kinematic chain, and if the motor completes the closure and the resetting torque corresponds to an abnormal rescuing torque, deducing that the wear corresponds to wear in the motor or parts involved in compressing the closure spring.

Techniques for video exchange are disclosed in which a video source sends redundant copies of video coded at a given presentation time. A decoder may determine, from metadata stored with a first decoded frame, whether other decoded frames have been designated as correlated to the first decoded frame. If so, the decoder may fetch other decoding frames using time indicator values of other decoded frames in metadata stored with the first decoded frame. When other decoded frame(s) are found, the decoder may blend content of the first coded frame and the other decoded frame(s). The decoder may render the blended frame. When one such coded frame is an intra-coded frame, the proposed technique may alleviate beating artifacts by blending recovered data of the intra-coded frame with recovered data of another frame, which may be inter-coded.

A remote-controlled mechanism according to an embodiment is used for coupling to a protective switching device to use a controllable drive device of the remote-controlled mechanism to actuate the coupled protective switching device. To this end, the remote-controlled mechanism includes: an actuating element operatively connectable to an actuating element of the coupled protective switching device and actuatable either by a remotely controllable drive device of the remote-controlled mechanism or manually; one or more sensor devices for capturing position data relating to a position of the actuating element of the remote-controlled mechanism; and a controller for evaluating the captured position data and for controlling the drive device via control commands. The controller is designed to disable the drive device upon an evaluation of the position data and/or of the control commands revealing that the actuating element of the remote-controlled mechanism has been switched off manually.
