Abstract: A light-modulating device includes optical microstructures, each including a topmost layer, a bottommost layer, and in-between layers. The topmost layer extends in a first predetermined axis. The bottommost layer extends in a last predetermined axis which turns about a center axis such that an incident light beam passing through the topmost layer in an incident route is modulated to permit the light beam emitting from the bottommost layer to impinge upon a solar concentrator disposed below the light-modulating device along an impinging route different from the incident route. The in-between layers are sequentially turned about the center axis by an incremental degree toward the last predetermined axis.

Abstract: The present disclosure is directed to a method for controlling a pitch angle of a rotor blade of a wind turbine. The method includes adjusting, with an actuator, the pitch angle of the rotor blade during a start-up sequence of the wind turbine. The actuator adjusts the pitch angle of the rotor blade by rotating the rotor blade about a pitch axis relative to a hub. The method also includes determining, with a controller, a minimum pitch angle threshold of the rotor blade based on a tip speed ratio of the rotor blade. The method further includes comparing, with the controller, a current pitch angle of the rotor blade to the minimum pitch angle threshold. When the pitch angle meets the minimum pitch angle threshold, the method includes preventing, with the actuator, the pitch angle of the rotor blade from exceeding the minimum pitch angle threshold.

Abstract: A method for detecting leakage at a fluid connection for a gas turbine fuel supply system is disclosed herein. The method includes closing a flow control valve at an upstream end of the fuel supply system and pressurizing the fuel supply system with a compressed medium via a compressed medium supply to a target pressure. The target pressure is less than a pressure threshold of a check valve that is disposed downstream from the compressed medium supply and upstream from a corresponding combustor of the gas turbine. The method further includes pointing a receiver portion of an ultrasonic detection device proximate to at least one tube fitting of the fuel supply system located between the flow control valve and a combustor which is fluidly coupled to the fuel supply system. Detection of an increase in sound level and/or the sound of popping at the tube fitting is indicative of a leak at the tube fitting.
