A method for determining and/or verifying a status of a door system, wherein the door system has at least one first subsystem and one second subsystem, includes the following steps determining at least one item of measurement information relating to the door system is determined in a measuring step, and determining and/or verifying the status of the door system using a model and using the at least one determined item of measurement information in a status determination step, wherein the model has a first model block for the first subsystem and a second model block for the second subsystem.

An assist apparatus for assisting a user or an occupant of a vehicle to get out of the vehicle, the assist apparatus configured to be capable of opening a door of the vehicle automatically upon a request operation for opening the door by the user.

An unmanned aerial vehicle airport, an unmanned aerial vehicle system, a tour inspection system and an unmanned aerial vehicle cruise system. The unmanned aerial vehicle airport comprises a support base, a parking apron, a protective cover and a protective cover opening and closing driving device. The parking apron is installed on the top of the support base; the protective cover covers the top of the apron; the protective cover opening and closing driving device is installed between the support base and the protective cover, and the protective cover opening and closing driving device is configured to cause a bar linkage mechanism to drive the protective cover to switch between an open position and a closed position. The unmanned aerial vehicle airport is provided with the protective cover for the parking apron. If the protective cover is open, the unmanned aerial vehicle is parked on the parking apron, and takes off from the parking apron.

The live well lid system may comprise a lid, a hinge, a motor, a lift arm, a lid track, and a local foot control. The live well lid system may be a system for covering and uncovering a live well of a boat by pivoting the lid of the live well responsive to input from the local foot control. The live well lid system may be adapted for a user to pivot the lid by operating the local foot control located proximate to the live well without diverting the attention of the user or requiring use of the user's hands. In some embodiments, a remote foot control may be a secondary control located at a remote location on the boat.

An opening-closing body control device for a vehicle includes: an opening-closing control unit configured to control an operation of an opening-closing body provided in an opening portion of a vehicle by controlling energization of a motor serving as a drive source. When the opening-closing body being moved based on a driving force of the motor is to be stopped, the opening-closing control unit sets a free running period during which free rotation of the motor is allowed, and executes brake control for generating a braking force in the motor after the free running period elapses.

The invention relates to a device for releasing and resetting a fire and smoke barrier. In a normal use state, a clutch member is held by an electromagnetic attraction unit, so that a push rod ejecting module cannot be actuated, and a door operator is controlled by a clutch module thereof. Upon power failure, for example upon an accident, the clutch member is released by the electromagnetic attraction unit, and a barrier release member is activated by the push rod ejecting module so as to shut the fire and smoke barrier. Upon power restoration, the clutch member is attracted and held by the electromagnetic attraction unit, and the push rod ejecting module is reset by a push rod resetting module. At the same time, the barrier release member is also reset.

A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer, reinforcing fibers, and at least one tribological modifier. The tribological modifier, in one embodiment, can comprise a graft copolymer. The use of a graft copolymer has been found to unexpectedly and dramatically improve noise generation when tested against various substrates, especially glass substrates.
