Abstract: A portable seisgun device providing a consistent signal for detection with sensor arrays and geophones in the course of seismic studies, and a self-contained transport mechanism. The device comprises a main platform, a muffling skirt and a gun stock mounted on a dolly. The platform provides a safe place to operate the device. The skirt both reduces noise and contains debris. The firing barrel fires a shotgun shell into the ground, producing the seismic signal. Interchangeable barrels permit different types of ammunition to be used. The dolly acts as both infrastructure and transport for the device and additional equipment, including over rough terrain.

Abstract: A modular structure is disclosed that includes a variety of separate units having an armored panel secured to a frame portion. The units, which exhibit a variety of shapes and dimensions, may be joined together to form modular structures with different configurations. For example, the units may be joined together to form an enclosed modular structure with a box-like configuration that is loaded onto a bed of a conventional truck for the transportation of troops or equipment. When joined, the various frame portions form a frame that extends around the modular structure and provides support, and the various panels are positioned adjacent to each other to form a shell that encloses the individuals or equipment.

Abstract: An organic cargo handling system, includes a tactical vehicle, a bed disposable on the vehicle, the bed including a tiltable bed portion, the tiltable bed portion including a quick hitch, the tiltable bed portion quick hitch is translatably disposed on a track, the track being operably coupled to the tiltable bed portion, quick hitch being powerable in a first direction along the track and being powerable in a second opposed direction along the track, and a cargo handling apparatus being couplable to the quick hitch for selective engagement with an article to be transported on the tactile vehicle to advance said article up the tiltable bed portion for loading thereon and to urge the article down the tiltable bed portion for offloading thereof. A vehicle bed and a method of deploying material in a field are further included.

Abstract: A high-mobility artillery cannon system transportable with the cargo envelop of a transport aircraft, includes a lightweight field howitzer, a medium tactical vehicle, and a bed disposable on the vehicle, the bed for receiving and supporting the howitzer such that the vehicle with the howitzer disposed on the bed is receivable within an envelop having substantially the dimensions of the cargo envelop defined within the C-130 type transport aircraft. A method of configuring a cannon system for transport the C-130 type transport aircraft is included.
