In one embodiment, a frame and stair system for engaging a wall includes multiple pad assemblies, a distal frame assembly, a lower proximal frame assembly, an upper proximal frame assembly, multiple stair assemblies, and multiple upper panel stair adapter brackets. A lower stair assembly is coupled with a left stair pad assembly, a right stair pad assembly, a left distal leveling pad, and a right distal leveling pad. A middle stair assembly is coupled with the distal frame assembly and the upper proximal frame assembly. An upper stair assembly is coupled with the upper proximal frame assembly. The upper proximal frame assembly is coupled with the lower proximal frame assembly. A left upper panel stair adapter bracket and a right upper panel stair adapter bracket are coupled with the upper stair assembly and are configured to engage an upper edge of the wall.

Frame and stair systems and methods

Ready armor modular protective systems that can be rapidly deployed in an urban environment. Exemplary armor systems include a container, and a wall assembly that fits inside of the container when in a collapsed configuration. The wall assembly includes a first end section, a second end section, a constraint mechanism, and first and second locking mechanisms. The first end section has a first space frame unit, and the second end section has second and third space frame units. A locking mechanism prevent relative vertical displacement from occurring between adjacent second and third space frame units. The constraint mechanism keeps the first and third space frame units at a fixed distance from one another. The constraint mechanism, when coupled with the first and third space frame units, keeps the locking mechanism from being removed from the second end section.

Ready armor protection for instant deployment and loading

A configuration, all components of which are man portable in some embodiments, for holding panels to protect assets against external force and impacts from airborne projectiles. An open box-like stackable frame module holds panels along a side of the frame. Multiple frames are connected to construct a protective barrier, such as a wall. Frames include provisions for connection in a vertical configuration so as to allow stacking of the frames to increase the height of the barrier. A method of installing is also provided.

Expedient retrofit for existing buildings

Ready armor modular protective systems that can be rapidly deployed in an urban environment. Exemplary armor systems include multiple space frame units. Adjacent space frame units can be coupled together with vertically adjustable coupling mechanisms. Coupling mechanisms (e.g. slot and pin connecting mechanisms) can facilitate relative displacement between adjacent space frame units when the units are connected. In this way, a wall of connected adjacent space frame units can be placed and/or moved along an uneven or irregular surface (e.g. having bumps or a grade) and the adjacent space frame units can remain in parallel and/or vertical orientation relative to one another. Suspension mechanisms can help to facilitate or enable rapid deployment of a ready armor modular protective system.

A modular protective system (MPS) Expedient Guard Tower and Fighting Position meeting multiple criteria for deployment and re-deployment in austere combat environments is disclosed as well as methods of assembly. The MPS Expedient Guard Tower and Fighting Position is lightweight such that it can be easily deployed by helicopter, requires no tools or equipment to assemble, and can be assembled very quickly by a team of four to six soldiers. The Modular Protective System (MPS) Expedient Guard Tower and Fighting Position can be easily recovered, i.e., disassembled and redeployed to a different location and as the title of the invention suggests, it is capable of being constructed in a non-elevated position or an elevated position. Accordingly, it may be used either as a guard tower, a fighting position, or an inspection station, etc., depending upon the particular need.

Transportable modular configuration for holding panels

Gallium nitride material devices and methods associated with the devices are described. The devices may be designed to provide enhanced thermal conduction and reduced thermal resistance. The increased thermal conduction through and out of the gallium nitride devices enhances operability of the devices, including providing excellent RF operation, reliability, and lifetime.

This invention pertains to an electronic device and to a method for making it. The device is a heterojunction transistor, particularly a high electron mobility transistor, characterized by presence of a 2 DEG channel. Transistors of this invention contain an AlGaN barrier and a GaN buffer, with the channel disposed, when present, at the interface of the barrier and the buffer. Surface treated with ammonia plasma resembles untreated surface. The method pertains to treatment of the device with ammonia plasma prior to passivation to extend reliability of the device beyond a period of time on the order of 300 hours of operation, the device typically being a 2 DEG AlGaN/GaN high electron mobility transistor with essentially no gate lag and with essentially no rf power output degradation.
