    摘要： The present invention relates to an ice detection system, in particular to a system for detecting icing conditions and a system for detecting the presence of ice formed on a structure, and the methods for doing the same.
    A method, apparatus and controller to detect the formation of ice on a structure are described. A heater of an ice protection system is driven and the rate of change of surface temperature is measured over several periods. A substantial deviation from a rate of change of surface temperature, which indicates the presence of ice on the surface of the structure, is detected.

    摘要： A link assembly has a pair of mechanical links pivotally connected to rotate relative to one another about a pivot axis. A cable protector is provided as part of the link assembly. The cable protector has a cup with an end wall which defines a first end of a winding chamber, and an annular side wall which extends from the end wall and defines a side of the winding chamber. A lid defines a second end of the winding chamber opposite to the first end. The lid is coupled to the cup by a bearing so that the cup and lid can rotate with respect to each other. An opening is formed in the side wall of the cup and a slot is formed in the lid. The assembly is fitted with a cable having a length, a width, and a thickness, wherein the width of the cable is greater than its thickness. The cable has a first portion which extends along a first one of the links and passes into the side of the winding chamber through the opening in the side wall of the cup, a second portion which extends along a second one of the links and passes into the second end of the winding chamber through the slot in the lid, and a rolled portion in the winding chamber in which the cable is wound into a roll, the roll including an outer turn which leads to the first portion and an inner turn which is inside the outer turn and leads to the second portion.

    摘要： A buoy is provided with first and second fixed hydrodynamic surfaces (15,16). When the buoy is towed through water by a tether (17), the first hydrodynamic surface (15) generates a downward force that reduces with increased speed through the water. The second hydrodynamic surface (16) generates an upward force that increases with increased speed through the water so that the buoy dives up to an upper critical speed through the water speed and rises beyond said upper critical speed through the water. The downward force of the first hydrodynamic surface (15) overcomes the buoyancy of the buoy at a lower critical speed through the water above, which the buoy dives. The hydrodynamic surface (15) comprises first fins (15) mounted on an outer casing (1) of the buoy and are spaced angularity and extend parallel to the centre axis of the buoy which is substantially aligned with the direction of towing. The second hydrodynamic surface (16) comprises second fins (16) mounted on the outer casing arranged upstream of the first fins (15) in the direction of towing. The second hydrodynamic surface (16) is set at an angle of incidence such that it creates a stalled flow condition at said upper critical speed through the water.
