Abstract: A digital content package includes first content comprising a video feature such as a motion picture or the like, and a user-selectable application configured to operate as follows. When activated using an icon off of a menu screen, the application records an identifier for scenes (discrete portions) of the first content that are selected by a user to generate a playlist. The user may select the scenes by indicating a start and end of each scene. The application saves the playlist locally, then uploads to a server. Via a user account at the server, a user may publish the playlist to a user-created distribution list, webpage, or other electronic publication, and modify the playlist by deleting or reordering scenes.

Abstract: A landing gear system for a vehicle includes a landing gear configured for reciprocating motion between a stowed position and a deployed position. The landing gear has a linkage with a first link rotatably coupled to a second link.

A fail-secure downlock includes first and second electromagnets fixedly positioned relative to the first and second links, respectively. The first electromagnet is proximate to the second electromagnet when the landing gear is in the stowed position. The first electromagnet is attracted to the second electromagnet when the downlock is in the locked state. The first electromagnet is repelled by the second electromagnet when the downlock is in the unlocked state.

Abstract: A landing gear system includes a landing gear assembly coupled to a body of a vehicle and configured for reciprocating motion between a retracted position and an extended position. A fail-secure uplock assembly is reciprocal between a locked state and an unlocked state. A first electromagnet and a first permanent magnet are mounted to the body, and a second electromagnet and a second permanent magnet are mounted to a component of the landing gear assembly.
