Abstract: Disclosed is an apparatus for maintaining a position of a vehicle door relative to a vehicle frame may include a link and a fastener. The link may have a first end and a second end. The first end may have a loop and the first end may be at an opposite end of the link from the second end. The fastener may be on a surface of the link and may be configured to fasten the link to the vehicle frame. A hook may be on the second end. The loop may be an arc or an incomplete circular portion. The vehicle may be a rotorcraft vehicle.

Abstract: Methods are disclosed for training an installer to cut a film without damaging an underlying substrate. The methods include the steps of applying a stretchable surface-protection film to an electrically-conductive substrate provided with at least one irregularity; and cutting the surface protection film with an electrically-conductive knife which, when in contact with the electrically-conductive substrate, causes one or more notifications to occur. Also disclosed are devices that may be used in carrying out the methods of the invention.

Abstract: A foldable fifth wheel trailer stabilizer device is disclosed. The device is attached to the trailer's king pin box and features two telescoping legs with adjustable knobs for length adjustment. The legs are equipped with chains for added support and are complemented by adjustable supporting members on the king pin box for support when folded and are not in use. In one embodiment, the device includes an additional telescoping leg connected to a horizontal member that spans the first and second legs. The additional leg is also adjustable in length and can be secured with chains for further support. The device is adaptable to various trailer heights and can be easily folded for convenient storage and transportation.

Abstract: Disclosed is an assembly and a vehicle and apparatus including the assembly, for maintaining a vehicle door in an open position may include at least one rod member configured to connect at a first end to the door and at a second end to a vehicle frame.
