| 20120060491 | REMOTELY ACTUATED WIND TUNNEL MODEL RUDDER USING SHAPE MEMORY ALLOY - A rotational actuator assembly employs a first torsion actuator having a shape memory alloy (SMA) tube with a first trained twist direction and a second torsion actuator having a SMA tube with an opposite trained twist direction collinear with the first torsion actuator with abutting proximal ends. A central fitting joins the proximal ends. A control system for temperature control of the first torsion actuator and second torsion actuator about an average temperature provides combined antagonistic rotation of the central fitting. | 03-15-2012 |

| 20090121587 | ENERGY SHUTTLE BASED HIGH ENERGY PIEZOELECTRIC APPARATUS AND METHOD - An energy harvester apparatus that includes a piezoelectric beam having opposing first and second ends, with the first end being fixedly supported to a support structure. A negative spring force subsystem has a first end fixedly secured against movement, and a second end secured to the second end of said piezoelectric beam. The negative spring force subsystem includes a linkage system and a biasing element operably associated with the linkage system for applying an adjustable, negative spring force to the piezoelectric beam to soften the piezoelectric beam. The negative spring force subsystem is adjusted to flex the beam sufficiently to overcome the inherent stiffness of the beam such that two stable positions for the beam are created. The beam is therefore able to oscillate between the two stable positions in an over center fashion in response to a low magnitude vibration signal. In various embodiments the system is implemented to provide an input drive signal to control various types of external devices. | 05-14-2009 |

| 20090133685 | HELIOSTAT ARRAY LAYOUTS FOR MULTI-TOWER CENTRAL RECEIVER SOLAR POWER PLANTS - A solar power plant includes central receiver modules arranged in a regular pattern. Each central receiver module includes a tower, a central receiver mounted on the tower, and a heliostat array bounded by a polygon. The heliostat array includes heliostats with mirrors for reflecting sunlight to the central receiver. The heliostats are grouped in linear rows and each of the rows is parallel to another row. The locations of the heliostats are staggered between adjacent rows. The power plant also includes a power block for aggregating power from the central receivers and power conduits for transferring power from the central receivers to the power block. | 05-28-2009 |
| 20090241938 | SOLAR THERMAL RECEIVER FOR MEDIUM- AND HIGH-TEMPERATURE APPLICATIONS - A receiver system for harnessing solar radiation. Embodiments of a receiver system include a receiver including one or more receiver elements, each receiver element including: a plurality of transparent tubes including a first tube and at least one second tube at least partially within the first tube; a first passage interposed between the first tube and the at least one second tube, the first passage having an inlet and an outlet; a second passage within the at least one second tube, the second passage having an inlet and an outlet; and an absorber in the at least one second tube, the absorber adapted to absorb the solar radiation. In some embodiments, a receiver further includes a housing having at least one transparent portion, the housing configured to enclose the plurality of receiver elements, whereby a third passage is formed between the first tube and the housing. | 10-01-2009 |
| 20090241939 | Solar Receivers with Internal Reflections and Flux-Limiting Patterns of Reflectivity - Solar receivers and particularly to solar receivers having one or more cavities and optionally having absorptivity/reflectivity patterns on surfaces and methods of reflective material application. | 10-01-2009 |

| 20110289822 | Terrestrial Arthropod Trap - The arthropod trap has a base with a plurality of sides that angle upwardly and inwardly toward a capture area in the center of the base. Multiple outwardly-projecting fins are disposed on or adjacent to the sides of the base. The fins also angle upwardly toward the capture area so that the fins guide arthropods into the capture area. The capture area includes a pitfall so that the arthropods topple through a pitfall opening and are retained in the pitfall. A trap cover fits over and at least partially conceals the capture area. In one embodiment, the trap cover provides a platform for the placement of light emitting diodes that emit light in a wavelength that appeals to the positive phototaxis instincts of the target arthropods. | 12-01-2011 |
