  • Patent number: 9696426
    Abstract: A system for scanning light to define a range gated signal includes a pulsed coherent light source that directs light into the atmosphere, a light gathering instrument that receives the light modified by atmospheric backscatter and transfers the light onto an image plane, a scanner that scans collimated light from the image plane to form a range gated signal from the light modified by atmospheric backscatter, a control circuit that coordinates timing of a scan rate of the scanner and a pulse rate of the pulsed coherent light source so that the range gated signal is formed according to a desired range gate, an optical device onto which an image of the range gated signal is scanned, and an interferometer to which the image of the range gated signal is directed by the optical device. The interferometer is configured to modify the image according to a desired analysis.

  • Publication number: 20150233962
    Abstract: An apparatus providing for simultaneous measurement of the wind upstream and downstream of a wind turbine uses either a single LIDAR beam split into two beams, each focused upstream or downstream of the windmill, or a multiple beam LIDAR with a first beam source aimed toward the upstream direction of the wind and a second beam source aimed at the downstream direction after the wind has passed through the wind turbine. The apparatus may also use LIDAR to measure wind direction and speed by making measurements along slightly different lines of sight, or by pointing the LIDAR in different directions. Two lines of sight allow measuring wind direction in the plane defined by the two lines of sight. Three non-coplanar lines of sight provide the information necessary to determine a full 3-dimensional wind velocity vector. Further, LIDAR may also be used to measure wind speed by estimating the wind velocity using inputs from both aerosol and molecular components.

  • Patent number: 9086488
    Abstract: One of first and second beams (28) of corresponding first and second light (13) are projected into an atmosphere (20) and at least one physical property of the atmosphere (20) is detected from the interference pattern (47) generated from the resulting scattered light (30). The first and second beams (20) are selected responsive to either a detected signal-to-noise ratio (SNR) or a detected aerosol-to-molecular ratio (AMR). The wavelength (740) of the first light (13) provides for either molecular or aerosol scattering, whereas the wavelength (738) of the second light (13) provides for primarily only aerosol scattering. In accordance with a second aspect, scattered light (30) from one or more beams (28) of substantially monochromatic light (13) projected into the atmosphere (20) and received from a plurality of interaction regions (17) or measurement volumes (52) provides for determining wind power (P*) within a region of the atmosphere (20).

  • Patent number: 8810796
    Abstract: A portion of a first portion of light (13, 90, 90?) from a source of light (11) is masked by a mask (138), and the resulting masked first portion of light (90?) is combined using a beam splitter optic (136) with at least one second portion of the light (30) that had been subject to scattering by a medium (20, 20?, 20?). The mask (138) is configured so that interference patterns (104, 47) generated from the first and at least one second portions of light are substantially mutually exclusive even though those interference patterns (104, 47) would otherwise overlap one another absent the mask (138).

  • Publication number: 20130184838
    Abstract: In a method for dynamically optimizing resource utilization in a system over time according to one or more objectives, data including information indicative of current environmental conditions, upcoming environmental conditions, a current state of a system configuration, and current system operating conditions is dynamically updated. Automatic analysis of the data using a probabilistic model based on conditional relationships is performed periodically. For each periodically generated set of possible system control actions, a probabilistic model is used to automatically analyze each possible system control action and an optimal system control action is selected based on a set of current utility functions. For each periodically generated set of possible system control actions, control of the system according to the optimal system control action selected from the possible system control actions.

  • Patent number: 8333347
    Abstract: For each capture mechanism of a plurality of three capture mechanisms, a necked coupling element received by a corresponding socket slides therealong and engages a corresponding latch lever biased in an open position and rotates the latch lever to a closed position as the necked coupling element is slid within the socket towards a bottom thereof. A latch locked biased against the latch lever engages a notch in the latch lever when the latch lever is closed so as to latch the latch lever in the closed position and thereby capture the necked coupling element within the socket. The latch lever is unlatched by releasing the latch lock from engagement with the latch. Different latch levers incorporate different shaped surfaces that engage different corresponding necked coupling elements captured thereby so as to provide for respectively constraining in one, two and three degrees-of-freedom, respectively.

  • Patent number: 8056864
    Abstract: A convex forward surface of a forward-biased probe head of a first portion of a docking system engages a central concave conical surface of a second portion of the docking system. A first linear actuator moves a flexible docking cable assembly relative to a support structure through bores therein and through the probe head. An aftward retraction of the docking cable assembly causes a linearly-actuated cam element thereof to rotate a rotary cam follower pivoted from the support structure, which engages an aft edge portion of the probe head, forcing the probe head forward. A plurality of distal coupling elements operatively coupled to the support structure around a central axis thereof engage with and become releasably captured by a corresponding socket and associated capture mechanism of a mating second portion of the docking system, and rigidized when the probe head is forced against the central concave conical surface.
