Abstract: An ocean current detection device and method based on double-helix and double-core vibration fiber-optic cable, comprises a double-core fiber-optic cable and a φ-OTDR system; the double-core fiber-optic cable comprises a first and a second optical fiber core, provided symmetrically in the double helix structure. The terminate ends of the first and the second optical fiber core are connected, and the start end of the first or the second optical fiber core is connected with the φ-OTDR system. When measuring the ocean current characteristics in the target sea area, the double-core fiber-optic cable is provided underwater to generate vortex-induced vibration. The φ-OTDR system is provided for emitting laser towards the cable, receiving returned double-core vibration signals, extracting vibration characteristics from the double-core vibration signals to determine ocean current characteristics, including ocean current flow velocity and direction, to improve the detection accuracy.

Abstract: Methods, apparatuses, and systems for collecting the installation error of the wind vane are provided. The image of the blades of the wind turbine and the outer rotor of the generator is obtained. It is determined whether the wind vane is aligned with the center line of the wind turbine, according to a relationship between the center line of the wind turbine and the orienting plane of the wind vane in the image. In a case that the wind vane is not aligned with the center line of the wind turbine, the deviation angle between the wind vane and the center line of the wind turbine is calculated, and a direction of the wind vane is corrected according to the deviation angle. Therefore, installation errors of the wind vane are accurately determined and corrected, and accuracy is improved for installation of the wind vane.

Abstract: System and method for remotely sensing the cross-flow orientation of a fluid (including a gaseous fluid) over an extended range. A Fourier transform of beam wander of a single beam can be used to determine the orientation of the flow field. Many applications depend upon accurate flow orientation data to provide correct information such as, for example, citing of turbines on wind farms and atmospheric/ocean weather prediction.

Abstract: A machine is disclosed for wind sensing on sailboats. Wind is important for sailing, but sailboats lean away from the wind when under sail. Vertical wind angles reduce the accuracy of existing anemometers. The cup blades disclosed here do not lose rotation speed when heeling over. Since it is now easy to have a sophisticated chartplotter display on a mobile device in waterproof case even on small boats, this waterproof wind sensor is a wireless “appcessory” that can talk to smartphones, tablets, computers, e-readers and marine electronics. The circuit board is encapsulated and is itself the wind direction arrow. A fluxgate compass on the circuit board provides wind direction. The apparatus is solar-powered, so there is no wiring to install or chafe. This allows a further inventive step for raising the anemometer using the mast track without needing to climb up or lower the mast.

Abstract: A portable device for checking wind direction discharges a visible, and optionally scented, vapor stream into the atmosphere in a well-defined reference direction. In some embodiments, the device includes a power source, a vessel having an internal plenum chamber storing a volume of air, a reservoir containing a vaporizable agent, a vaporizing element associated with the vaporizable agent, and a pressure switch. The vessel is deformable to generate an airflow that operates the pressure switch to temporarily connect the power source to the vaporizing element, thereby energizing the vaporizing element to generate vapor. The airflow also carries the vapor into the atmosphere as a visible vapor stream flowing in the reference direction. The reservoir and vaporizing element may be carried in a cartridge removably mounted on the device. Other embodiments operate similarly, but use alternative means for generating gaseous flow to operate the switch and/or carry vapor into the atmosphere.

Abstract: The sensor comprises a reference bolometer and a plurality of sensing bolometers. Each sensing bolometer is arranged adjacent to the reference bolometer. Each bolometer comprises (i) a substrate, (ii) a cap structure connected to the substrate, the cap structure configured to define a cavity between an inner surface of the cap structure and a first surface of the substrate, (iii) an absorber connected the substrate and arranged within the cavity, the absorber configured to absorb infrared radiation within the cavity, and (iv) a readout circuit connected to the absorber and configured to provide a signal that indicates an amount of infrared radiation absorbed by the absorber. The cap structure of the reference bolometer blocks infrared radiation from entering the cavity from outside the cap structure. The cap structure of each sensing bolometers allows infrared radiation to enter the cavity from outside the cap structure.
