Abstract: This invention deals with a novel general concept for a multi-wavelength switching ensemble which is controlled electrically, electromagetically, or magnetically. A switching system is presented that achieves electrical isolation between the input and output channels, and yet permits the input to control the output. It allows a full 180 degree rotation of the beam which greatly exceeds the rotational capability of conventional systems. Furthermore, the instant invention permits less costly and greater ease of manufacture while providing independent amplitude and frequency modulation between the input and output channels.

Abstract: This invention deals with the broad general concept for active reflection or projection illumination and image formation. A mini-optics reflection and focussing system is presented that ranges from interior illumination, to exterior illumination, to large scale space based illumination, to ordinary and to telescopic image formation. It can be used both as a source of illumination, and to project images, figures, and the written word. This novel system is uniquely distinct and different from prior art direct viewing gyricon displays, allowing it to be more versatile, economical, and practical with broader applications such as dynamic full color displays. In most cases it can operate with greater simplicity and efficiency. Furthermore in its capacity as a high altitude active reflector of solar radiation, it can be utilized to supply illumination, energy, and provide climate control.

Abstract: This invention relates generally to method and apparatus for solar-boost assist and solar-sail assist by a mini-optics light concentrator system utilizing a dynamic ensemble of mini-mirrors. In the boost phase of a rocket ship launch, the system focusses solar energy into the rocket chamber to raise the temperature of the propellant and increase the impulse. In the mid-course phase, the system focusses solar energy onto the rocket's solar sail to increase the thrust. In both cases, the system reduces the weight of the rocket by providing a weightless source of thrust.
