Various embodiments of the present invention are directed towards a system and methods for generating three dimensional (3D) images with increased composite vertical field of view and composite resolution for a spinning three-dimensional sensor, based on actuating the sensor to generate a plurality of sensor axis orientations as a function of rotation of the actuator. The output data from the sensor, such as a spinning LIDAR, is transformable as a function of the actuator angle to generate three dimensional imagery.

This underwater device is twin-motor underwater floating-type power generation device that is provided with: a device main body that is equipped with a pair of pods that have a turbine, and with a connecting beam that connects these pods together in parallel with each other; a sinker; and tether cables that tether the device main body to the seabed via this sinker. The respective turbines of the pods are each provided with variable pitch turbine blades. This device is also provided with a depth meter that detects deviation in posture in the roll direction that is generated in the pair of pods, and a posture controller that controls the pitch of the variable pitch turbine blades of the respective turbines so as to nullify any deviation in posture in the roll direction that has been generated in the pair of pods and has been detected by the depth meter.

A method for controlling a wind turbine via an ultrasonic wind sensor includes: transmitting, by a first ultrasonic transceiver, an ultrasonic packet at a first time and receiving, by a second ultrasonic transceiver, the ultrasonic packet at a second time; identifying wind properties based on the first time and the second time; transmitting the identified wind properties to a programmable logic controller (PLC) interfaced with the wind sensor and a turbine controller, wherein the interface with the turbine controller includes one of a plurality of communication topologies; processing the identified wind properties for output to the turbine controller based on a specific communication topology, wherein the PLC is configured to process the identified wind properties for output based on each of the plurality of communication topologies; transmitting the processed wind properties to the turbine controller; and controlling, by the turbine controller, a wind turbine based on the wind properties.

A wind turbine including a rotor, a nacelle, a support structure for the nacelle and at least one wind sensing apparatus mounted on the support structure.

A method for detecting a shadow condition from a wind turbine and a system for detecting a shadow condition are provided. An atmospheric condition detected from an atmospheric condition detector is compared to a threshold. From the comparison a determination is made that the atmospheric condition is shadow producing. The shadow condition is detected using said determination.

A wind farm aircraft beacon system, a wind farm having the wind farm aircraft beacon system and a method for providing a wind farm with a beacon are provided. A plurality of aircraft beacon devices are provided and at least one transmitting station is used to emit electromagnetic waves and/or sound waves. A number of receiving stations are provided that are at least a multiple of the number of transmitting stations. At least two receiving stations receive electromagnetic waves and/or sound waves and an evaluation device detects for flying object positions by evaluating emitted and received electromagnetic waves or sound waves, for example, using transit time determination. The wind farm aircraft beacon system also comprises a switching device for switching at least one of the aircraft beacon devices on or off on the basis of the flying object positions.
