Abstract: A singular modular barrel assembly allows a projectile weapon to fire both tubular arrow type projectiles and internal bullet type projectiles. The singular modular barrel assembly includes components that can be attached or detached from the singular modular barrel assembly, thereby, altering the barrel configuration in order to allow the projectile weapon to fire either tubular arrow type projectiles or internal bullet type projectiles. The singular modular barrel assembly includes an outer tube, an inner tube, and a barrel-attachment body. The outer tube is a barrel shroud that protects and aligns the inner tube. The inner tube allows a tubular arrow type projectile to be loaded or allows passage for an internal bullet type projectile. The barrel-attachment body allows the singular modular barrel assembly to be attached onto the existing barrel of a projectile weapon. The singular modular barrel assembly can be used with either pyrotechnic or pneumatic projectile weapons.

Abstract: A chair can include a chair back, or backrest, that is coupled to a base of a chair above a seat of the chair. A tilt mechanism can attach the backrest to the base at spaced apart locations. In some embodiments, the tilt mechanism can be configured so that the backrest rotates about multiple pivots as it reclines from an upright position to a reclined position to drive forward motion of the seat during recline of the backrest.

Abstract: An energy storage component (ESC) enclosure is provided. The ESC enclosure includes a plurality of ESC modules. Each ESC module includes at least one side portion having a plurality of side fastening mechanisms configured to be coupled to an adjacent ESC module, wherein the plurality of ESC modules is coupled together via the plurality of side fastening mechanisms to form an ESC enclosure. The ESC enclosure further includes a plurality of shelving kits, each shelving kit mounted to one of the ESC modules. The ESC enclosure further includes a roof that is coupled to the plurality of ESC modules, and a plurality of panels coupled to the plurality of ESC modules about a perimeter of the ESC enclosure to form a shared air space within the ESC enclosure.
