Abstract: An air-redirection formation for a tip portion of an aerofoil such as an aircraft wing includes: a first portion, which includes a first surface which forms a continuation of the aerodynamic lifting surface of the wing, and which is for directing vortices away from the aerofoil; and a second portion, which is spaced from the first portion and which is positioned to generate uplift due to the directed vortices.

Abstract: A plurality of electromagnetic radiation capture units are positioned under a focusing unit such as a dome, such that incoming electromagnetic radiation incident on the dome is deflected by it, to reach each of the capture units with a different timing and intensity. The profile for the timings and intensities can be determined for a given transmitter using a calibration signal, and the profile is then used to extra data from data signals transmitted by the transmitter.

Abstract: Wide aperture optical communications systems and methods are disclosed. A first employs two lens arrays, arranged facing each other, and with one of the MLAs movable relative to the other. A second aspect employs a plurality of electromagnetic radiation capture units positioned under a focusing unit such as a dome, such that incoming electromagnetic radiation incident on the dome is deflected by it, to reach each of the capture units with a different timing and intensity. The profile for the timings and intensities can be determined for a given transmitter using a calibration signal, and the profile is then used to extra data from data signals transmitted by the transmitter.

Abstract: A system and method evaluate product substitutions along multiple criteria in response to a sales opportunity, for instance, providing sales recommendations of configurable products in response to a customer request based on propensity functions. A customer propensity is determined to estimate attractiveness of a substitute product to a customer based on one or more attributes. A seller propensity is determined to estimate attractiveness to a seller of selling the substitute product based on one or more attributes. The customer propensity and the seller propensity are combined to find a plurality of substitute products.
