Abstract: A firearm discharge gas flow control device can comprise a first gas chamber fluidly connectable to a muzzle end of a firearm to allow a projectile to pass through and to receive a first portion of a discharge gas generated by firing the projectile. The device can also comprise a second gas chamber fluidly isolated from the first gas chamber and fluidly connectable to the muzzle end of the firearm to receive a second portion of the discharge gas, the second gas chamber having a flow control barrier to modify a flow of the second portion of the discharge gas.

Abstract: An interchangeable, modular firearm muzzle mountable system can include a first firearm muzzle mountable device and a second firearm muzzle mountable device. Each device can have an inlet end coupling feature proximate to an inlet end of a central chamber and an outlet end coupling feature proximate to an outlet of the central chamber. The central chamber can be oriented along a central axis within an outer shell and the inlet and the outlet can be configured to allow a projectile from a firearm to pass along the central axis. The inlet end coupling feature of the first device can be removably coupleable with a muzzle end of a firearm and the inlet end coupling feature of the second device can be removably coupleable with the outlet end coupling feature of the first device beyond the muzzle end of the firearm.

Abstract: An interchangeable, modular firearm muzzle mountable device can include a central chamber oriented along a central axis within an outer shell. The central chamber can have an inlet at an inlet end and an outlet at an outlet end to allow a projectile from a firearm to pass along the central axis. The device can also include an inlet end coupling feature proximate to the inlet end, to removably couple with a muzzle end of a firearm. Additionally, the device can include an outlet end coupling feature proximate to the outlet end, to removably couple with a secondary firearm muzzle mountable device beyond the muzzle end of the firearm.

Abstract: An energy capture and control device is disclosed and described. The device can include a central chamber oriented along a central axis within an outer shell, said central chamber having an inlet configured to receive a high energy material from a high energy outlet. An off axis chamber can be oriented within the outer shell in fluid communication with the central chamber. The off axis chamber can have a fluid outlet and multiple internal walls to produce a serpentine fluid pathway which dissipates energy transferred from the high energy material.

Abstract: An acoustic and heat control device is disclosed and described. The device can include a central chamber oriented along a central axis within an outer shell, said central chamber having an inlet configured to receive a high energy material from a high energy outlet. Additionally, the device can include a damper disposed proximate to the central chamber and comprising an energy absorbent material. In one aspect, the device can be used with a firearm.

Abstract: An Advanced Packet Based Integrated Communications System has the ability to provide commercial customers with converged services including local and long distance voice, data communications and videoconferencing and which also provides a platform to deliver value added services such as managed services, hosting, storage, messaging, and E-Business content. The integrated communications system comprises an integrated packet-based network infrastructure operable to provide networked converged communications, an information management platform operable to support handling of orders, initiating services provisioning, maintaining service quality, billing, and administration, and an activation engine operable to provide end-to-end services provisioning. The integrated packet-based network infrastructure replaces a traditional circuit switched network.
