Abstract: A recoilless gun system, comprising a gun assembly and associated ammunition for use with the gun assembly employs an integral barrel and a rear inserted ammunition round. The recoilless gun system may combine a laser initiator and a polymer cased ammunition to enable a lightweight system. In such embodiments, the cartridge case is made from a polymer that resists high pressure before extruding into small gaps.

The second longitudinal member axis is perpendicular to the support axis. A third longitudinal member is coupled to the second longitudinal member to be rotatable around a third longitudinal member axis relative to the second longitudinal member, rotatable with the second longitudinal member relative to the first longitudinal member, and rotatable with the first longitudinal member relative to the longitudinal support. The third longitudinal axis is perpendicular to the second longitudinal member axis. The module is connected to the third longitudinal member.

Abstract: A remote weapon station (RWS) system for an unmanned ground vehicle (UGV) includes a dedicated weapon, multi-axis gimbal and ammunition handling capabilities with all operations functioning remotely and wirelessly. The RWS system is a gas powered, or self-powered, belt fed, rotating bolt lock weapon. In addition, the RWS is man-portable and air-droppable as the major subsystems may be latched together in the field without tooling or needing to make electrical connections.

Abstract: A process and device for enhancing the chemical protection capability of a collective protection filter whereby the process stream exiting the collective protection filter is passed through an Auxiliary Filter. The auxiliary filter containing an ammonia removal media, such as zirconium hydroxide impregnated with zinc chloride (ZnCl2/Zr(OH)4), an oxidizing media, preferably zirconium hydroxide impregnated with potassium permanganate (KMnO4/Zr(OH)4), and a methyl bromide removal media, preferably activated carbon impregnated with triethylenediamine (TEDA/carbon). The auxiliary filter and process are configured to remove toxic industrial chemicals including NH3, NOx (mixtures of NO and NO2) and CH2O, and CH3Br.

Abstract: We disclose a novel methodology for wireless networks that optimizes the transmission probability, transmit power at an agent, and the reflection matrix of an IRS for covert RF communications. Key features include: (1) An exact closed-form expression for the expected detection error probability (DEP) at an adversary is provided considering the transmission probability at the agent; and (2) a novel method to optimize the transmission probability, transmit power at the agent and the reflection matrix of the IRS with the goal of maximizing the achievable rate at a client while ensuring a covertness constraint is developed. More specifically, the method may require only one-dimensional line search schemes, achieves near-optimal performance, and exhibits enhanced achievable data rate when compared to the conventional technique without the transmission probability optimization.

Abstract: A material closure assembly including a material closure, such as zipper or a hook and loop fastener, having a first portion and a second portion that are configured to be releasably joined together; an electrical circuit that is configured to be closed when the first portion of the material closure is entirely joined with the second portion of the material closure; and an first indicator that is electrically connected to the electrical circuit and configured to indicate that the first portion of the material closure is entirely joined with the second portion of the material closure. The material closure assembly thus providing an active feedback system for closures on garments and personal protective equipment (PPE) to alert wearer of incomplete seals between interfaces on modular PPE which could result in the wearer of the PPE being exposed to the surrounding environment outside the PPE.
