  • Patent number: 9503653
    Abstract: A method for determining an attitude of a star sensor based on a rolling shutter imaging is provided. The method comprises: optimizing a relation among an exposure time, a line readout time, an interline integral interval time and a frame processing time of an image for the rolling shutter imaging by using a rolling shutter model of an image sensor in the star sensor based on a line; predicting and extracting locations of M navigation stars comprised in a star map in the star sensor according to the optimized relation among the exposure time, the line readout time, the interline integral interval time and the frame processing time; and transferring an updated the attitude matrix and an updated angular velocity of the star sensor sequentially until a final attitude matrix and a final angular velocity of the star sensor are obtained.

  • Publication number: 20150203876
    Abstract: Recombinant bacteria capable of metabolizing sucrose are described. The recombinant bacteria comprise in their genome or on at least one recombinant construct, a novel nucleotide sequence encoding a polypeptide having sucrose transporter activity and a nucleotide sequence encoding a polypeptide having sucrose hydrolase activity. These nucleotide sequences are each operably linked to the same or a different promoter. Recombinant bacteria capable of metabolizing sucrose to produce glycerol and/or glycerol-derived products such as 1,3-propanediol and 3-hydroxypropionic acid are also described.

  • Patent number: 8433515
    Abstract: A method for measuring a precision of a star sensor and a system using the same may be provided. The method may comprise steps of: 1) fixing the star sensor on the Earth; 2) inputting a current time (T) of a measuring start time relative to a J2000.0 time; 3) determining a directional vector of the navigation star in a J2000.0 Cartesian coordinate system at the current time (T) according to a right ascension and a declination of the navigation star in the J2000.0 Cartesian coordinate system and visual movement parameters (??, ??) of the navigation star in the direction of the right ascension and the declination which are stored in the star sensor; 4) converting the directional vector of the navigation star in the J2000.

  • Patent number: 6576333
    Abstract: This invention provides a composite material having a matrix of structural material containing embedded zones of soft elastic material and zones of solid relatively high density material within the soft elastic material. By selecting a particular resonance frequency for the subunits of soft elastic material and solid high density material, frequencies just lower than the resonance frequencies will be unable to propagate through the material and be strongly reflected or absorbed. Such material may be used in the manufacture of filters or shields against particular target frequencies. Subunits having a variety of resonance frequencies may provide a broader range of frequencies that the material may shield.
