| 20100158433 | METHOD AND APPARATUS FOR MEASURING FIBER TWIST BY POLARIZATION TRACKING - An apparatus and accompanying method to measure fiber twist. The method includes independent determination of fiber bending by measuring strain sensing in outer cores of the same fiber. The apparatus includes a multi-core optical fiber comprising a center core and a plurality of peripheral cores at a distance radially from the center core and running parallel to the center core. The center core includes at least one fiber Bragg grating with polarization-dependent reflectivity. The fiber Bragg grating reflects the launched light as reflected light. The apparatus includes a multi-core optical fiber bend sensing system operable to communicate with the multi-core optical fiber. The multi-core optical fiber bend sensing system is operable to sense a bend in the multi-core optical fiber. The apparatus includes a processor operable to communicate with the polarization controller. The apparatus includes a polarization vector analyzer operable to communicate electronically with the processor, and optically with a portion of the light launched into the central core of the optical fiber. The polarization vector analyzer is operable to measure the state of polarization of the launched light. The polarization controller is operable to align the polarization of the launched light with the minor axis or the major axis of birefringence of the FBG. The processor is operable, after the polarization controller aligns the polarization of the launched light, to determine a twist in the multi-core optical fiber based on the polarization of the launched light and the bend in the multi-core optical fiber. | 06-24-2010 |

| 20090173376 | SOLAR COLLECTOR DESICCANT SYSTEM - The present invention is a desiccant system for controlling moisture in a solar collector. The desiccant system has a desiccant bed enclosed within a housing, and is thermally coupled to the solar collector as well as being fluidly coupled to it through an orifice. Waste heat from the solar collector is conducted to the desiccant system and is used to regenerate the desiccant bed. The desiccant system includes moisture barriers which cause moisture from the desiccant to preferentially be released to the external environment rather than entering the solar collector. | 07-09-2009 |

| 20090261802 | SIMULATOR SYSTEM AND METHOD FOR MEASURING ACCEPTANCE ANGLE CHARACTERISTICS OF A SOLAR CONCENTRATOR - A simulator system for simulating operation of a solar module comprises a frame for holding the solar module in a testing position, a light source positioned adjacent to the solar module for directing light from the light source to the solar module, and a movable assembly for simulating movement of a solar tracker system, wherein the movable assembly moves in two axes to change an incident angle of the light with respect to the testing position of the solar module. | 10-22-2009 |
| 20090261810 | SIMULATOR SYSTEM AND METHOD FOR MEASURING CURRENT VOLTAGE CHARACTERISTIC CURVES OF A SOLAR CONCENTRATOR - A simulator system for simulating operation of a solar panel is disclosed which comprises a solar panel, a reflector positioned across from the solar panel, a light source positioned adjacent to the solar panel for directing light from the light source to the reflector for reflecting light to the solar panel, a sensor positioned adjacent to the solar panel for sensing light reflected from the reflector and for generating a signal indicative of a parameter of the reflected light with the signal having an increasing portion, a flat peak portion, and a decreasing portion, and a circuit for measuring a characteristic of the solar panel when the signal reaches the flat peak portion. | 10-22-2009 |

| 20120037390 | FREE-MASS AND INTERFACE CONFIGURATIONS OF HAMMERING MECHANISMS - The design of the free-mass in an ultrasonic driller/corer (USDC) has been refined in order to improve the performance and operational reliability of the system. In one embodiment, the improvements in performance and operational reliability include decreasing the impact surface area of the free-mass to increase the transfer of impact energy from the piezoelectric transducer and reductions in the likelihood that the system will jam. | 02-16-2012 |
