Abstract: A modular ramp for creating a ski jump on a modern naval vehicles is provided. Generally, the system allows a user to manipulate a ramp surface in a way that best suits the needs of the user at that time. The system generally comprises a framework, interlinking tracks, and control arm. The control arm manipulates the position of the framework, which in turn manipulates the surface created by the interlinking tracks. The modular ramp may also comprise mechanical joints and a hinge, which may allow the surface to be manipulated in multiple directions.

Abstract: An improved aircraft system is provided. The improved aircraft system comprises an adjustable vortices device that may be attached to an aircraft to create various vortices effects, which increase take-off weight and improve low-speed handling of the aircraft. The adjustable vortices device comprises a linear actuator, a pivot mechanism, and a vortex generator. The pivot mechanism is operably connected to the linear actuator in a way such that the translational energy of the linear actuator causes the pivot mechanism to rotate about a central axis. The vortex generator is moveably attached to a surface of the aircraft and coupled to the pivot mechanism in a way such that rotating the pivot mechanism causes the vortex generator to rotate about a central axis, which alters the angle the vortex generators move through the air.

Abstract: An improved firearm system is provided. The improved firearm system comprises an improved firearm cartridge for use in firearm designed to fire the improved firearm cartridge. The firearm cartridge comprises a projectile substantially seated within a cartridge casing, which reduces the length of the firearm cartridge. The cartridge casing may be modified to accept more than one primer. A firing pin of the firearm may be modified so it may strike each of the primers of the cartridge casing. A bolt body may be modified so that it has two pieces connected by a pin so that it may house the modified firing pin. Because the length of the firearm cartridge is reduced, the length of a magazine that holds firearm cartridges may also be reduced. This allows a handle of the firearm to be moved forward so that the magazine may be inserted through the handle.

Abstract: A sealed cover and plastic cartridge combination for electrical connections providing sealing, strain relief, mechanical retention, electrical insulation and flex relief similar to that achieved using an over-molded design includes a plastic cartridge of integral construction or composed of two or more parts, in either case housing one or more contacts of the connections.
