To reduce or prevent erroneous recognition by a user concerning the roof operation of a convertible vehicle whose roof is adapted to be opened and closed. A roof opening/closing system of a convertible vehicle includes an opening/closing device for opening/closing the roof of the convertible vehicle; and a controller for determining, with respect to at least one of the opening and closing operations by the opening/closing device, whether to enable or disable the operation; and a notifying device for notifying a user whether the operation is enabled or disabled as determined by the controller. For example, in the case where the burning protection is turned off, following the determination based on the condition relevant to burning protection lift of prohibition of the roof operation is notified when other permitting conditions for the roof operation are fulfilled.

A system for moving an aircraft door from an open position towards a closed position. The system includes an aircraft door actuator, an input receiving primary power from a primary power supply to power movement of the aircraft door from the open position towards the closed position, a secondary power supply to power the aircraft door actuator to move the aircraft door from the open position towards the closed position, and a controller configured to cause the secondary power supply to power the aircraft door actuator to cause the aircraft door actuator to move the aircraft door from the open position towards the closed position, on the basis of a determination that insufficient primary power is available from the primary power supply via the input to move the aircraft door from the open position towards the closed position.

A hydraulic piston actuator, which may be used for an aircraft nacelle assembly, includes a housing, a piston, an end gland, and a bearing ring. The housing is concentrically disposed along an axis. The piston is adapted to axially reciprocate within the housing. The end gland is disposed radially between the housing and the piston. The bearing ring is disposed radially between the end gland and the piston.

A switched-mode light-emitting diode (LED) display unit satisfying fire-fighting smoke exhaust and ventilation requirements includes an LED display unit, a mounting member, an opening-closing actuator and a pressing member. The LED display unit is mounted on the mounting member and the mounting member is mounted on a display panel by an opening-closing actuator and pressed against the display panel by a pressing member. The switched-mode LED display unit provides the pressing member that works to release the pressed mounting member after obtaining a triggering command and the opening-closing actuator that turns on the LED display unit subsequently, thereby meeting the fire smoke exhaust ventilation requirement of the internal surface or the external surface of a building.

A motor vehicle is disclosed having a safety system that includes an electronic controller controlling an electronically controlled mechanism in response to inputs from a number of rear parking sensors to prevent movement of a rear closure of the motor vehicle in a closing direction when more than one object is sensed to be within a rear protection zone and the rear closure member is in a fully open position.

A trailer door system that comprises at least one trailer door assembly operably engaged with the trailer; and at least one driving assembly operably engaged with the trailer and the at least one trailer door assembly. The at least one driving assembly further comprises an expansion assembly operably engaged with the at least one trailer door assembly. The at least one driving assembly further comprises a rotary actuator operably engaged with the expansion assembly, wherein the rotary actuator is configured to transition the expansion assembly between a collapsed position and an expanded position for pivoting the at least one trailer door assembly between a closed position and an opened position about an axis parallel to a vertical axis defined by the trailer. A trailer monitoring system may be included with the trailer door system for automating the state of the trailer during a towing operation.

A railroad hopper car body includes a set of hopper and hopper discharges. Egress of lading from the discharges is governed by movable doors that swing between a closed position and an open position. The motion is driven by a mechanical transmission that is itself driven by an actuator. Each pair of doors is driven by a single actuator. The actuator is mounted to act through the center sill. A portion, or substantially all, of the actuator may be mounted in a predominantly squat, vertical orientation within the center sill. In alternate embodiments, the transmission output may be bifurcated. The center sill bottom flange may be narrower adjacent to the doors. The mechanism may have a secondary lock. The mechanism may have an auxiliary manual release.

A method of accessing a cargo in a trailer. The method includes steps of engaging the trailer to a vehicle, wherein the trailer comprises at least one trailer door assembly operably engaged with at least one driving assembly; unlocking a trailer door of the at least one trailer door assembly via at least one locking assembly; actuating the trailer door, via a rotary actuator, from a closed position to an opened position; pivoting the trailer door, via an expansion assembly of the at least one driving assembly, from the closed position to the opened position; and providing access to the cargo inside of the trailer.

An integrated system for releasing trapped persons in a vehicle (PARIS) includes a central management unit (CPU) to which sensors (D1, D2, . . . Dn), an input-output socket (S) for connecting a service computer and control switches or buttons, and at least the following are connected at an output of the central management unit: an automatic seatbelt cutting system (SBC), a system for automatically opening door locks and bolts and locking them in the open position (LOB), and a system for automatically swinging doors and locking them in the open position (DOB).

A swing gate mechanism to swing open an overhead lift gate system includes an overhead swing gate. The overhead swing gate has a pivot side and a catch side. A first gate power arm is configured to move along a first overhead guide track on a first side of the overhead lift gate system. A second gate power arm is configured to move along a second overhead guide track on a second side of the overhead lift gate system. At least one hinge is connected between the pivot side of the overhead swing gate and the first gate power arm. The at least one hinge is configured to allow the overhead swing gate to swing open by rotating about the first gate power arm.
