  • Publication number: 20100085632
    Abstract: An optical parametric oscillator (OPO) is described that efficiently converts a near-infrared laser beam to tunable mid-infrared wavelength output. In some embodiments, the OPO includes an optical resonator containing a nonlinear crystal, such as periodically-poled lithium niobate. The OPO is pumped by a continuous-wave fiber-laser source having a low-power oscillator and a high-power amplifier, or using just a power oscillator. The fiber oscillator produces a single-frequency output defined by a distributed-feedback (DFB) structure of the fiber. The DFB-fiber-laser output is amplified to a pump level consistent with exceeding an oscillation threshold in the OPO in which only one of two generated waves (“signal” and “idler”) is resonant within the optical cavity.

  • Patent number: 7690595
    Abstract: A system, method, and apparatus for throat corner scoop offtake for mixed compression inlets for high speed aircraft engine applications is disclosed. The throat corner scoops are small air intakes located inside the large mixed compression inlet. They are positioned in a region otherwise prone to generate low pressure airflow. The throat corner scoops capture and remove the low pressure airflow from the bulk stream that is passed on to the engine. This location also provides inlet stability enhancement, and the airflow is used on the auxiliary systems.

  • Patent number: 7692603
    Abstract: A spiral planar antenna includes more than two spiral arms. Each arm includes at least a portion that is coiled. The antenna may operate from approximately 50 MHz to upwards of several GHz within a payload space of only about 5.75 inches in diameter and less than one inch in height, with approximately 5 dBi or less of measured axial ratio.

  • Publication number: 20100082254
    Abstract: Systems and methods of enhancing crude oil recovery include radiating electromagnetic energy in the form of focused electromagnetic pulses into a permeable formation containing the crude oil and/or fluid via an array of antennae transmitting immediately in the far field. The electromagnetic pulses are focused at the depth of the fluid reservoir. Pulses will be reflected by the fluid according to the fluid material (e.g. oil vs. water) and/or the strata (e.g. rock, sand, etc.). An array of receiver antennae may be used to initially establish a reference of the reflected electromagnetic pattern, and then operated in conjunction with the transmit array to monitor the relative horizontal movement of oil and/or water within the subterranean reservoir.
