The present invention is a method for predicting the wind speed in the rotor plane (PR) of a wind turbine (1), by accounting for an induction factor used in a wind evolution model implemented by a Kalman filter. The invention also is a method for controlling a wind turbine (1), a computer program product, a LiDAR sensor (2) and a wind turbine (1), which uses the wind prediction determined with the method according to the invention.

A device may receive a power demand for a load and a weather forecast for a time period. The device may determine a first supply of power available from a photo-voltaic (PV) installation for the time period based on the weather forecast. The device may determine a power deficit for the time period based on the power demand and the first supply of power. The device may determine a first cost associated with utilizing a second supply of power available from a battery and a second cost associated with utilizing a third supply of power available from an engine for the time period. The device may determine a power source to overcome the power deficit based on the first cost and the second cost and may cause the PV installation and the power source to supply power to satisfy the power demand for the load.

A thermal-break assembly including a thermal-insulation block configured to be installed between a first floor section and a second floor section. A weight-receiving device is configured to receive the thermal-insulation block. Spaced-apart reinforcing bars extend through, and beyond, the thermal-insulation block; this is done in such a way that the spaced-apart reinforcing bars, in use, extend into the first floor section and into the second floor section (once the thermal-insulation block is installed therebetween). The spaced-apart reinforcing bars are in intimate contact with the weight-receiving device.

The present disclosure relates generally to methods, devices and systems for insulation, e.g., of cavities associated with walls, ceilings, floors and other building structures, with foam insulation. In one aspect, the disclosure provides a method for providing a cavity of a building with an expanded foam insulation. The method includes dispensing an amount of an expanding foam insulation into the cavity, the expanding foam insulation being dispensable and expandable to provide the expanded foam insulation material, the expanding foam insulation material formed from a premix comprising at least one polyol, at least one polyisocyanate, a blowing agent, and an encapsulated catalyst, the encapsulated catalyst comprising a plurality of catalyst capsules, each comprising an amount of catalyst and a capsule shell encapsulating the catalyst, wherein the dispensing is performed to apply a force to the encapsulated catalyst sufficient to break capsules and release catalyst, the released catalyst initiating reaction between the at least one polyol and the at least one isocyanate; and then allowing the dispensed amount of expanding foam insulation to substantially finish expanding after it is dispensed in the cavity, thereby forming the expanded foam insulation in the cavity.

A DC to AC converter is configured to convert DC power from a floating DC power source to AC power having a desired voltage and waveform. A plurality of capacitors is charged to discrete voltages from the DC power. A switching network selectively connects the capacitors in series to an AC output node. For selected capacitors, either the associated voltage or the inverse of the associated voltage is summed together (non-selected capacitors contribute zero volts to the sum). The sum voltage is output to the AC output node at two values, and the voltage is jittered between these two values at a high frequency in order to approximate intermediate values. The two values jittered between, and the values and timing of the intermediate values, are controlled to construct a desired waveform, such as an approximation to a sine wave.

A modular housing structure comprising a plurality of modular elements each having a relative bearing structure defining an inner housing volume, and relative removable union components/devices for the reciprocal connection, associated with the bearing structure, wherein each of the modular elements comprises relative removable union components/devices for the reciprocal connection, and wherein the union components/devices are associated with the bearing structure and are of the magnetic type.

According to one aspect of the present invention, a resin composition for an insulating layer includes: an olefinic resin as a main component; and a metal deactivator, wherein a content of the metal deactivator exceeds 0.05% by mass, and wherein a melting point of the metal deactivator is greater than or equal to 200° C.

An exterior insulation panel for installation in an exterior building envelope of a building. The insulation panel has an interior face for facing toward an interior space of the building, an exterior face lying opposite the interior face for facing away from the interior space of the building, and a foam core laminated with a perforated exterior facer on one or both faces of the panel, at which the exterior facer defines an uncovered outermost layer of the panel. Each perforated facer comprises openings therein through which moisture is migratable into the foam core during moisture-rich environmental conditions, for temporary holding of the excess moisture until such conditions subside.

A high frequency signal transmission cable includes a conductor, an insulator provided over a periphery of the conductor, a plating layer provided over a periphery of the insulator, and a sheath provided over a periphery of the plating layer. A crack suppressing layer is provided between the insulator and the plating layer, in such a manner as to remain in contact with the insulator while being provided with the plating layer over an outer surface of that crack suppressing layer. The crack suppressing layer is composed of a resin film to suppress the occurrence of a cracking in the plating layer by bending while moving in a longitudinal direction of the cable relative to a bending of the insulator.

A battery charge and discharge cycling with predictive load and availability control system has a server and a load control device. The server predicts usage and future solar capacity at the specific sites where the battery packs are in use. The batteries are cycled near the lower end of capacity (state of charge or SoC), which extends life. Further, the load control device can reduce a battery's SoC if the weather forecast is sunny. The load control device may turn on appliances in the home to use excess energy that is generated by the solar system.
