Abstract: A method of fabricating a surface for reducing ice adhesion surface which includes providing a surface of a cured material and impacting the surface of the cured material with a pressurized jet of a fluid material to plastically deform the cured material to enable the surface to reduce ice adhesion strength on the surface.

Abstract: The present invention relates to methods for joining and for improving interfacial strength of joints in objects of fibre-containing composite materials, such as epoxy/glass fibre composite materials of a wind turbine blade, as well as fibre reinforced composite materials, laminates and other interconnected objects prepared by this method. In particular wind turbine blades prepared by this method are described. The present invention further relates to robots and robotic tools for carrying out the described methods for joining objects of fibre-containing composite materials.

Abstract: A system, method and software for protecting wind turbines from lightning strikes, as well as a wind turbine comprising the system for lightning protection, wherein at least one lightning strike protection element of said LSP system is ionized prior to a lightning strike, thus reducing the chance of damaging unprotected part(s) of the blade(s) of the wind turbine.

Abstract: A tissue retractor for retracting tissue opened by an incision, said tissue retractor including a base support unit having a topside and an underside. The topside comprises at least one securing mechanism and the underside is adapted to be conformable and to be removably attachable to a surface proximate to the incision. The tissue retractor also includes at least one tissue hook having a tissue engagement portion and a mounting portion, wherein the tissue engagement portion is capable of engaging at least the periphery of the incision. The tissue retractor also includes at least one retractable member substantially inelastic in its central longitudinal axis and bendable in any axes deviating from said central longitudinal axis.
