  • Patent number: 10566698
    Abstract: At least one embodiment of the present invention includes an antenna system comprising a multifocal reflector having at least two reflecting segments having different curvatures defining at least two different spaced apart focal points, such that the multifocal reflector is configured and operable to receive radiation incident on the segments at different incident angles within a certain angular range, and reflect the incident radiation onto the at least two focal points in a focal axis, thereby creating focused radiation formed by at least two differently focused portions of radiation; a phased array feed antenna unit located perpendicularly to the focal axis and comprising a plurality of antenna elements for receiving/transmitting at least two differently focused portions, and a feed network connected to the plurality of the antenna elements for selectively actuating the antenna elements for performing electronic scanning of the space area aimed at detecting target.

  • Patent number: 9029677
    Abstract: A method for composing a musical is carried out by identifying spectral data characterizing a selected chemical composition, said spectral data representing a plurality of transmittance peaks for the selected chemical composition in a spectral range (e.g., a wave number range), including identifying the spectral range and transmittance values and positions of a sequence of transmittance peaks within the spectral range; assigning a melody duration to the identified spectral range; generating a sequence of musical tones by assigning the identified transmittance values to musical tones to the sequence of transmittance peaks; and assigning a duration to each musical tone. A computer-readable medium includes code for carrying out the method on a general-purpose computer.
