Abstract: An optical fiber assembly includes a ferrule body with a plurality of optical fibers and an end of each optical fiber positioned adjacent the front face of the ferrule body. A beam-expanding element is positioned adjacent the front face of the ferrule body including a lens array aligned with the optical fibers. The lens array is spaced from the optical fibers by a predetermined distance to form a gap with an index-matched medium within the gap. A method of manufacturing the optical fiber assembly is also provided.

Abstract: A rifle is provided. The rifle comprises a barrel, a handguard partly axially surrounding the barrel, and a modular accessory system. The modular accessory system comprises a housing and a modular accessory support system positioned within the housing, wherein the support system includes at least two modular accessory slots. The modular accessory system also comprises a modular accessory removably secured and individually adjustable within each slot. The housing partly axially surrounds the barrel and is positioned axially adjacent to the handguard such that a combination of the handguard and the housing surrounds the barrel completely in an axial manner. Support system configurations of preferably either tray-type or platform-type may be contemplated. The modular accessory system may further comprise a common power source and a display system. A modular accessory system for rifles capable of exchangeably mounting accessories thereto in plug-and-play fashion is therefore achieved.

Abstract: A firearm accessory system can include a housing designed to be attached to a firearm such that the housing is disposed underneath a barrel of the firearm. The housing can include a plurality of cavities formed therein, each of the cavities being configured to enclose and power a plug-and-play lighting or targeting accessory for use with the firearm. The housing can be configured to power all of the accessories received within the plurality of cavities from a single power source. In some embodiments, the housing can include a plurality of accessory compartments formed therein to receive and retain one or more accessories for use with the firearm. Each accessory compartment can be configured to provide an electrical connection between an accessory received in the compartment and a source of power and operatively position the associated accessory with respect to the housing. Firearms incorporating a firearm accessory system are also described.

Abstract: The blood sampling assembly includes a retractable double-ended needle so that a vial may be passed through an opposed end of the needle to obtain a blood sample. The assembly includes a hollow cylinder including circumferentially spaced seat tabs which allow a needle seat and the needle supported thereon to be released upon rotation of tube with respect to hollow cylinder. The extractor assembly includes a stopper for maintaining a vacuum within tube to withdraw the needle to a retracted position within the tube upon rotation of the tube, the end cap, and the stopper retainer. A stopper tab positioner rotationally connects the stopper to the cylinder.

Abstract: The blood sampling assembly includes a retractable double-ended needle 26 so that a vial may be passed through an opposed end 30 of the needle to obtain a blood sample. The assembly includes a hollow cylinder 10 including circumferentially spaced seat tabs 20 which allow a needle seat 40 and the needle 26 supported thereon to be released upon rotation of tube 62 with respect to hollow cylinder 10. The extractor assembly includes a stopper 66 for maintaining a vacuum within tube 62 to withdraw the needle to a retracted position within the tube 62 upon rotation of the tube 62, the end cap 92, and the stopper retainer 70. A stopper tab positioner 84 rotationally connects the stopper 66 to the cylinder 10.

Abstract: The present application relates generally to a system for the practice of high density cell culture. The system employs the use of two tanks; a cell growth tank having multiple cell growth chambers, is preferably situated within a reservoir tank. A series of pumps and outlets provide an even and continuous circulation of media and air to the system and between tanks. The system is designed to operate with minimal supervision and constantly over long periods of time.
