The present invention relates to a method of manufacturing a wind turbine blade, comprising arranging one or more layers of fibre material and a preform in a mould (66), injecting the one or more layers of fibre material and the preform (76) with a curable resin, and curing the resin. The preform (76) is impregnated with a curing promoter such that the concentration of curing promoter varies spatially within the preform.

Methods and systems are provided for fabricating a composite structure. In one example, the composite structure may include a honeycomb core sandwiched between face sheets. An edge of the honeycomb core may be abraded and a top face sheet may be perforated. As such, a likelihood of delamination of the composite structure during a curing step may be reduced.

Embodiments of the present disclosure are directed to a moldable input device. A moldable input device may comprise a thermoplastic polymer layer that is heatable to achieve a moldable condition that allows for a reconfiguration of the thermoplastic polymer layer. After heating, the thermoplastic polymer layer may then be placed on a rigid outer shell of an input device and molded by user engagement (e.g., a user's hand). After a certain period of time, the thermoplastic polymer layer will have cooled and hardened, capturing the molding impressions and imprints of the user's hand. The rigid outer shell may then be affixed to a base plate of an input device, and the rigid outer shell and the base plate may form an enclosed cavity, wherein circuitry for an input device is maintained and protected. In some examples, the thermoplastic polymer may be polycaprolactone or ethylene vinyl acetate.

A method for manufacturing a case for a mobile device with a screen, in which the case has a band arranged to surround the edge of the device, includes supplying a band having a layer of flexible polymer; and in either an insert molding process or in a dual injection process, applying damping material on the layer of the flexible polymer of the band. The damping material has a plurality of integrally formed protrusions projecting inwardly from a substantial portion of the inner periphery of the band to engage with the device. The protrusions are arranged such that, in use there is substantially no contact between the band and the device other than through the protrusion. Further, the protrusions are provided at least in the corner regions of the case.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.
