Abstract: A field-ready oven has reinforced telescoped side walls that extend and hold a base, shelf, tray support and cover spaced apart. A low air intake and a semipermeable membrane deliver air and vapor fuel to catalyst pads on the shelf. Radiant heat from exothermic reaction is diffused over a bottom of a tray. Hot gas circulates around the diffuser and tray with a chimney effect before exhausting. A lid on the cover lifts for access to the tray. A fuel container in the oven forces fuel through a capillary restriction to limit fuel flow. A spring in the container is released to start fuel flow.

Abstract: The present invention relates to apparatus and methods to provide a control system for the purpose of redirecting light from a source onto a target. The present invention appreciates that the optical properties of light that is both modified and/or distributed, e.g. by diffraction, diffusion, or some other process, and also redirected by a heliostat, can be a function of how the light redirecting element is aimed. This means that the aim of the light redirecting element can be precisely determined once the aim of the modified and/or distributed light is known. Advantageously, the characteristics of modified and/or distributed light indicative of how that light is aimed can be determined from locations outside the zone of concentrated illumination in which sensors are at undue risk.
