Abstract: A lock release control device for an opening and closing body configured to control an opening and closing body that opens and closes an opening portion of a vehicle. The opening and closing body comes into contact with a sealing member provided on a vehicle body side of the vehicle in a fully closed state. The vehicle includes a locking device and an opening and closing actuator. The locking device restrains the opening and closing body in a fully closed position. The opening and closing actuator displaces the opening and closing body by rotation of a motor to change the opening and closing body from one of two states including an open state and a closed state to another of the states. The lock release control device is configured to execute an open command acquisition process, a pull-in process, and a lock release process.

Abstract: A method (1000) for testing of a door operator (100), the door operator (100) being configured to via a mechanism (104) move at least one door leaf (200) between a first position and a second position. The door operator (100) includes a first drive unit (102) configured to optionally move the door leaf (200) into said first position and a control unit (103) connected to a sensor (105). The method includes the steps of initiating a simulated powerless mode, measuring operation of the door leaf by the sensor, and comparing measured values of movement with reference values.

Abstract: A railcar system that includes a railcar with a discharge opening and a longitudinal gate positioned adjacent to the discharge opening. The system further includes a driving system connected to the longitudinal gate that is configured to move the longitudinal gate between a closed position and an open position. The system further includes a controller connected to the driving system that causes the driving system to position the longitudinal gate in the closed position, position the longitudinal gate in the open position, and position the longitudinal gate to remain an at least partially open position. The longitudinal gate is less than fully open when the longitudinal gate is in the at least partially open position.

Abstract: A scissor drive includes two legs which can be pivoted relative to one another about a pivot axis, each having a longitudinal axis and designed to be connected to an external component, and a motor/gear assembly that drives the relative pivoting movement of the two legs. The first leg includes a housing that is hollow at least in portions, a cavity defined in the hollow housing extending at least in portions along the longitudinal axis of the first leg, and the motor/gear assembly being received in the housing of the first leg at least in portions in the portion of the cavity that extends along the longitudinal axis of the first leg.
