  • Publication number: 20110220094
    Abstract: A solar collection system having a secondary reflector is provided. The secondary reflector may be located above a field of primary reflectors and below a solar receiver. The secondary reflector may form a portion of an ellipse or macrofocal ellipse and be operable to reflect at least a portion of the solar radiation reflected by the primary reflectors onto the solar receiver. The secondary reflector may be disposed away from the solar receiver and associated tertiary reflectors such that it does not intercept reflected solar radiation from the outer primary reflectors that would otherwise have struck the solar receiver and tertiary reflectors had the secondary reflector not been present.

  • Patent number: 7765705
    Abstract: A measuring device comprising a base, feet connected to the base, and an inclinometer mounted on the base is used to characterize a surface. The feet are placed in direct contact with the surface at a predetermined position. The inclinometer measures the angle of the surface relative to gravity at the predetermined position. In some embodiments, multiple measuring devices are connected to an arm, in order to measure different positions on the surface simultaneously. The arm may be moved by an actuator to the next predetermined position on the surface. In some embodiments, multiple measuring devices are connected to a frame that is substantially the same size as the surface to be characterized, such that the entire surface can be characterized without moving the frame.
