Abstract: An actuated feedforward controlled solar tracker system including a sub-frame supporting at least one solar panel, a post supporting the sub-frame, and a linking mechanism connecting the sub-frame and post, where the linking mechanism includes a first axle, second axle and body member. The linking mechanism's first and second axles are disposed orthogonal to each other and are separated by the body member. The system includes at least two linear actuators, a rotational joint connecting the linear actuators and sub-frame, and a driver system that drives the actuators. Additionally, the system includes a feedforward control system including a computer that calculates desired positions of the linear actuators using multiple inputs and communicates with the driver system to drive the linear actuators, and a feedback control system that relays information gathered by sensor devices to the feedforward control system, where the feedforward and feedback control systems function in an integrated manner.

Abstract: An x-ray beam processor system that includes an x-ray beam generator for generating x-ray beams; a collecting cone that includes multilayer waveguide optics; a condensing cone that includes multilayer waveguide optics; and polycapillary tubes with channels, where the polycapillary tubes link the collecting cone and the condensing cone.

Abstract: An x-ray beam processor and system that includes an x-ray beam generator for generating x-ray beams; a mirror shield for shielding the x-ray beams from select areas; a cylindrical waveguide for guiding x-ray beams traveling through the waveguide, which includes a plurality of entry ports and exit ports; a plurality of ring-shaped mirrors disposed adjacent to and generally parallel with the entry ports and the exit ports and sharing a common axis “X” with the waveguide; and mountings for mounting the mirrors to the waveguide.
