Systems and methods for aerial dispersion of materials

Aerial dispersion systems that may be employed to allow rapid and temporary conversion of aircraft for aerial dispersion purposes, such as aerial fire-fighting. The aerial dispersion systems may be implemented using modular components that may be configured for compatibility with conventional cargo loading and unloading systems of modern aircraft, including side-loading cargo systems of wide body passenger and cargo aircraft having high lift capacities. The aerial dispersion systems may be rapidly installed in a large fleet of high capacity aircraft in response to a wildfire or other rapidly-developing emergency such as an oil spill, chemical or biological contamination incident, building or refinery fire, etc. After use, the aircraft of the fleet may be rapidly de-modified and returned to original condition. The aerial dispersion systems may be operated with a fleet of aircraft in a coordinated manner, for example, as part of an aerial firefighting formation having multiple aircraft sharing information and / or common control.

Multiple leg tumbling robot

A robot or vehicle locomotes by tumbling. Legs distributed over the surface of the robot individually extend or retract. A control system coordinates the action of the legs to cause the robot to tumble in any direction. A robot using this form of locomotion is highly maneuverable, can climb slopes, and can step over obstacles. It can provide a smooth ride on rugged terrain. A variation can jump into the air and land safely. A variation can be built with as few as six moving parts, can fold to fit into a projectile, and instantly unfold on landing. It may use airbags instead of legs. It can include a video system without moving parts that produces a stable, non-tumbling view of its surroundings while tumbling. It is an ideal remotely operated vehicle for search and rescue, firefighting, or reconnaissance for the military or police.
