Abstract: A floating structure is described. The floating structure includes a floating platform disposed at a water surface, a mooring system and a dumping system. The mooring system is configured for mooring one side of the floating platform to a sea floor, thereby to permit rotation of the floating structure and to provide a desired orientation down-wind with respect to an anchor point. The dumping system is arranged at one side of the floating platform and is configured for absorbing wave energy and stresses imparted by the motion of waves in order to stabilize a horizontal position of the floating structure down-wind during a storm against the waves.

Abstract: The present disclosure provides a computer implemented method of providing an indicator useful for piloting an aircraft. The aircraft comprises an antenna configured to communicate with a transceiver. The method comprises: obtaining an antenna envelope characterizing directions relative to the aircraft for which a directive gain of the antenna exceeds a predetermined threshold; determining a direction of the transceiver relative to the aircraft; calculating a maneuvering range of the aircraft by comparing the antenna envelope and the transceiver direction, wherein the maneuvering range is indicative of eligible orientations of the aircraft for maintaining the transceiver within the antenna envelope; and outputting data indicative of the maneuvering range.

Abstract: A system for cancelling interference in a wireless network, the system comprising apparatus for computing and outputting at least N weighting vectors; and apparatus for cancelling interference from antennae outputs received by the system using the weighting vectors respectively by converting the weighting vectors into FIR filter coefficients and applying FIR filters corresponding to the FIR filter coefficients to derivatives of antennae outputs received by the system. The apparatus for computing and outputting weighting vectors may be operative by estimating a spatial signature while distinguishing interference spatial signature from desired signal spatial signature although both are received simultaneously.
