Abstract: An autonomous sailing vessel may include a hull, a mast, a sail, and a sail release device. The mast may be mechanically coupled to the hull. The sail may be mechanically coupled to the mast. The sail release device may be operably coupled to the sail and may be configured to automatically release the sail to spill excess wind. Alternatively or additionally, the sail may include a fore sail element coupled to the mast and an aft sail element rotatably coupled at a fore of the aft sail element to an aft of the fore sail element. In this and other embodiments, the autonomous sailing vessel may further include a camber control assembly to automatically set a camber angle between the fore and aft sail elements.

Abstract: A security pocket door traverses within a security bulkhead wall that defines a pocket, within which the pocket door traverses, and a through passage to permit people, carts and luggage to pass. The pocket door has an upper door track mechanism and a lower door track mechanism that engages a corresponding upper and lower track mechanism of the bulkhead and floor, respectively. The bulkhead door locks with at least one solenoid with a locking pin that engages a hole in a tab of the pocket door. The locking pin creates a magnetic field with a magnet located in the tab to send a signal to the flight deck in order to indicate a closed and locked or an unlocked pocket door condition. When the pocket door is in its closed position, the door perimeter overlaps the bulkhead on at least three sides of the door and also overlaps with the floor.

Abstract: Modular vehicle units, including aircraft interior storage units, and associated methods are disclosed herein. One embodiment is directed toward an aircraft system that includes a modular unit and at least one latch or releasable coupler to couple the modular unit to at least one surface of an aircraft. Another embodiment is directed toward a vehicle system that includes a vehicle having a first surface and a second surface. A modular unit can be positioned generally against the first and second surfaces. The system can further include at least one latch or releasable coupler to couple the modular unit to at least one of the first and second surfaces. In further embodiments, the system can include at least one locating device for positioning the modular unit.
