Disclosed herein is a fault diagnosis apparatus of a rapid charging system for a vehicle including an external device configured to exchange power with a vehicle battery, a power transfer unit including a three-phase motor, an inverter connected to the battery in parallel and connected to the three-phase motor, and one or more relays connected to the three-phase motor and configured to transfer power between the external device and the battery, and a controller configured to control the on and off functions of the relay, to control driving of the inverter to generate voltages applied to one end of each of the relays, and to diagnose fault of relays by comparing voltages of both ends of the relays while turning the relays on/off.

A production planning system (6) for a raw materials industry plant (ANL), which determines the production planning data (Pi) thereof and specifies said data to the automation system (1) of the plant (ANL). A state monitoring system (7) determines previous and future anticipated states (Z1) of components of the plant (ANL). A quality determination system (8) determines states (Z2) of output products (Ai) produced and still to be produced by the plant (ANL) and/or past and future states (Z3) of the plant (ANL) as a whole. A maintenance planning system (9) and/or the production planning system (6) receive, from the state monitoring system (7), the states (Z1) of the components of the plant (ANL), determined by the state monitoring system (7) and, from the quality determination system (8), the states (Z2 and Z3) of the output products (Ai) and/or of the plant (ANL) as a whole, determined by the quality determination system (8). They consider the data received from the state monitoring system (7) and from the quality determination system (8) in the determination of maintenance planning data (W) and/or the production planning data (Pi).

A device for capturing operating data of a motor-driven tool includes a capture and/or evaluation device, an operating data memory, and/or a communication interface. These components draw electric power from an electrochemical energy store during operation. An operating mode control device operates the components at a temperature above a temperature limit value in a normal temperature operating mode and at a temperature equal to or below the temperature limit value in a low temperature operating mode different from the normal mode, wherein less electric power is drawn in the low temperature operating mode.

Worksite data from an unmanned aerial vehicle (UAV) is received and an indication of the worksite data is generated. A quality of the received worksite data is calculated based on quality data within the received worksite data. Control signals are generated and provided to the UAV based on the calculated quality of the received worksite data. Additional worksite data corresponding to a modified surface of a worksite area is received from a plurality of mobile machines at the worksite area. A worksite error is calculated for the modified surface of the worksite area. Control signals are generated and provided to a UAV based on the calculated worksite error for the modified surface of the worksite area.

A system and method for monitoring a dry gas seal positionable between a stationary housing and a rotatable shaft. A plurality of sense elements may rotate in response to the rotation of the rotatable shaft and a speed sensor may sense the speed of the rotatable shaft at speeds below one thousand rotations per minute based on sensing the plurality of sense elements. An acoustic emissions sensor may sense when a first seal face and a second seal face forming a seal interface of the dry gas seal are in an operational condition relative to one another. A processor may receive output signals from the speed sensor and the acoustic emissions sensor, and may establish an operating condition of the dry gas seal based on the signal from the speed sensor when the first seal face and the second seal face reach the operational condition relative to one another.
