A wave receiving plate is pivotably supported by a support device in the wave force generation system and includes a flexible plate in at least a part of the wave receiving plate.

A torque bracket arrangement for a wind power gearbox for transmitting a supporting force to a support structure of a wind power plant includes at least one radial support arm having an associated opening configured to receive a horizontal support pin. The at least one radial support arm is provided on a gearbox side and is configured to establish a detachable connection to at least one corresponding opening of a support eyelet unit arranged on the support structure. The at least one corresponding opening of the support eyelet unit includes an elastomer bearing bush into which the horizontal support pin is configured to be inserted. The elastomer bearing bush has differing rigidities depending on the load. The elastomer bearing bush consists of at least one soft region of low rigidity and at least one comparatively harder region of greater rigidity.

Disclosed herein are flexible wave energy converters that actuate electrical generators with dynamic strain (e.g., flexing, stretching, twisting, distension) to convert wave energy to electrical energy. The flexible wave energy converter utilizes flexible electric generators embedded throughout the wave-energy converter's flexible body.

A rotor blade for a wind turbine includes at least one blade segment with at least one shell member defining an airfoil surface. The shell member(s) includes a sandwich panel configuration having one or more inner skin layers, a core material, and one or more outer skin layers. The outer skin layer(s) includes one or more first fibers, whereas the inner skin layer(s) includes one or more different second fibers. Further, the first fiber(s) of the outer skin layer(s) have a higher elastic modulus than the second fiber(s) of the inner skin layer(s).

A turbine blade for a wind turbine is provided, including a blade body with a leading-edge, wherein the blade body is provided with a form changing device covering the leading-edge and extending at least partially along the leading-edge, which form changing device includes a shell fixed to the blade body, which shell is movable by an actuator between a first position close to the leading-edge and a second position distanced to the leading-edge.

A plurality of wind turbine blades or blade portions have substantially the same size and outer geometrical shape, and corresponding plies of the blades or blade portions having the same position within the respective wind turbine blades or blade portions have different fibre orientation angles relative to a pitch axis of the respective wind turbine blade or blade portion. By changing the fibre orientation angles of the corresponding plies a bend-to-twist coupling of the blade or blade portions may be varied amongst the plurality of blades or blade portions. The blades may then be tailored according to their siting within or on a wind turbine park. A common mould shape may be used across the plurality of wind turbine blades or blade portions, together with a more streamlined blade design process.

A roll-diaphragm compressor that includes a compressor head with an interface wall that defines a concave portion and with an apex portion having an inlet port and outlet port. The roll-diaphragm compressor can also include a flexible roll-diaphragm coupled to the compressor head about an edge with the roll-diaphragm driven in a rolling motion against the interface wall. The roll-diaphragm compressor can also include a compression chamber defined by the compressor head and roll-diaphragm that is configured for receiving a fluid via the inlet port in a first state, compressing the fluid based on the volume of the compression chamber being made smaller, and expelling the fluid in a second state via the outlet port.

An impeller includes a hub and a blade supported by the hub. The impeller has a stored configuration in which the blade is compressed so that its distal end moves towards the hub, and a deployed configuration in which the blade extends away from the hub. The impeller may be part of a pump for pumping fluids, such as blood, and may include a cannula having a proximal portion with a fixed diameter, and a distal portion with an expandable diameter. The impeller may reside in the expandable portion of the cannula. The cannula may have a compressed diameter which allows it to be inserted percutaneously into a patient. Once at a desired location, the expandable portion of the cannula may be expanded and the impeller expanded to the deployed configuration. A flexible drive shaft may extend through the cannula for rotationally driving the impeller within the patient.
