20120060900 | Cd-Free, Oxide Buffer Layers For Thin Film CIGS Solar Cells By Chemical Solution Deposition Methods - A process described herein provides an economical means for producing the oxide-based buffer layers using a wet chemical CSD process wherein the desired buffer layer material results from the evaporation of a chemical already containing the material in solution. Thus, no residual liquid chemical elements remain after deposition, and as there is no reaction to create the buffer material, as is the case with CdS CBD, the liquid elements in CSD have sufficiently long shelf life after mixing to as to improve manufacturability and further reduce waste. Furthermore, as there is no in-chamber reaction to create the buffer material solution, there are many options for delivering said solution to the CIGS absorber layer. Finally, as the oxide films for the CdS replacement have inherently better transmission in the blue spectrum, aggressive thinning of films to improve current generation is unnecessary. | 03-15-2012 |

20100253998 | VERY HIGH POWER PULSED FIBER LASER - A high power integrated fiber laser system includes cascaded amplifiers that utilize low numerical aperture fiber amplifiers. The system is rugged and lightweight. | 10-07-2010 |
20110037970 | Laser Doppler Velocimeter - A laser Doppler velocimeter is formed using a fiber laser as the lasing medium. Within the velocimeter, all optical signals, transmitted and received, are conveyed by optical fibers. An amplifier amplifies a source laser, which is then transmitted to one or more transceivers. The one or more transceivers, each projecting along a different axis, and each with a single optical fiber input/output interface act as both the transmission device to focus the radiation at a target region, and as the receiving system for collecting reflected radiation. The transceivers each include an amplifier to further amplify the radiation received from the laser source. The one or more transceivers transmit radiation simultaneously to the target region, and may be located remotely from the laser source. The portion of the reflected radiation collected by the receiving system is analyzed to determine the Doppler shift caused by targets at the focal point of the one or more transceivers. | 02-17-2011 |
20120206712 | Laser Wind Velocimeter With Multiple Radiation Sources - A system and method for measuring wind velocities are provided. A laser wind velocimeter with a radiation source includes a fiber laser. All optical signals, transmitted and received, are conveyed by optical fibers. An amplifier amplifies a source laser, which is then transmitted to one or more transceivers. The one or more transceivers, each projecting along a different axis, and each with a single optical fiber input/output interface act as both the transmission device to focus the radiation at a target region, and as the receiving system for collecting reflected radiation. The one or more transceivers transmit radiation to the target region. A portion of the reflected radiation collected by the receiving system is analyzed to determine the Doppler shift, which can me used to measure wind velocity | 08-16-2012 |
20130033742 | VERY HIGH POWER PULSED FIBER LASER - A pulsed fiber laser including fiber preamplifier and power amplifier stages is disclosed. A fiber preamplifier includes first and second preamplifier stages that receive and amplify a seed pulse. A filter isolator placed between the preamplifier stages suppresses noise from the first preamplifier stage. An acoustic optical modulator located in the second preamplifier stage eliminates unwanted wavelengths from the amplified seed pulse received from the first preamplifier stage. The pulsed fiber laser is rugged and lightweight. | 02-07-2013 |

20130325213 | LDV for Airdrops - A method of using a light detection system for increasing the accuracy of a precision airdrop is described. Radiation is transmitted to target areas between an airborne vehicle and a dropzone target. Scattered radiation is received from the target areas. Respective wind characteristics are determined from the scattered radiation and a wind velocity map is generated, based on the respective wind characteristics, between the airborne vehicle, and at least the dropzone target. An aerial release point for the precision airdrop is computed based on the generated wind velocity map and a location of the dropzone target. | 12-05-2013 |

20090140885 | Optical System for Detecting and Displaying Aircraft Position and Environment During Landing and Takeoff - A system and method uses light signals to detect and display the position of an airborne vehicle, such as a helicopter, during takeoff or landing or low speed, low altitude operation. A transmitter on the vehicle emits light signals while an optical receiver retrieves reflected light signals. Using light detection and ranging techniques, various parameters, such as altitude, ground speed and relative wind, are calculated based on the Doppler shift within the reflected light signals. The signals are transmitted in three different directions to facilitate the measurements of different Doppler shifts. The parameters are also displayed on a screen or other visual device within the vehicle. | 06-04-2009 |

20080267817 | WATER MANAGEMENT SYSTEM FOR STERILIZER - A portable steam sterilizer for surgical and dental instruments includes an outer casing and a pressure chamber configured to receive steam therein. A tray is configured to hold the instruments and is releasably received within the pressure chamber while a boiler is in fluid communication with the pressure chamber for providing steam thereto. The sterilizer further includes a container for receiving condensed steam evacuated from the pressure chamber. The container is spaced from the outer casing and includes a main body and a lid that is substantially non-rotationally coupled to the main body. A conduit is coupled to the lid and fluid communicates the container with the pressure chamber. The main body of the container may include a base while the lid may include a wall oriented generally orthogonal to the base. | 10-30-2008 |
20080299003 | PORTABLE STERILIZING APPARATUS FOR SURGICAL AND DENTAL INSTRUMENTS - A portable steam sterilizer for surgical instruments includes a tray configured to hold the instruments and a pressure chamber. The pressure chamber includes a cavity portion and a handle portion. The cavity portion includes a set of walls and is configured to releasably receive the tray, while the handle portion is coupled to the tray for selectively inserting and removing the tray respectively into and from within the cavity portion. The handle portion is sealingly engageable with the cavity portion to thereby define the pressure chamber. A steam inlet fluidly communicates the pressure chamber with a source of steam to selectively permit steam to flow from the source of steam and into the pressure chamber. A steam outlet fluidly communicates the pressure chamber with a steam management assembly to selectively permit steam to flow from the pressure chamber and into the steam management assembly. | 12-04-2008 |
