  • Patent number: 6720917
    Abstract: An improved global positioning system satellite signal acquisition method. The method of the invention reduces the number of operations in the block correlation used in determining Doppler frequency and time of the received GPS C/A or P(Y) codes.
    Type: Grant
    Filed: December 4, 2000
    Date of Patent: April 13, 2004
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventors: David M. Lin, James B. Y. Tsui
  • Publication number: 20030105285
    Abstract: The invention provides methods and compositions relating to odorant receptors, including a general expression cloning methodology which is useful for identifying novel G protein-coupled receptors and a novel family of odorant receptors and related nucleic acids, ligands, agonists and antagonists. These compositions provide a wide variety of applications such as screening for related receptors, and by modulating the function of the disclosed receptors by modulating their expression or contacting them with agonists, antagonist or ligands modulating reproductive/sexual and non-sexual social behaviors mediated via the olfactory system, reproductive physiologies and olfactory system regulated feeding behaviors, migratory behaviors and events such as conception, implantation, estrous and menstruation.

  • Patent number: 6567042
    Abstract: An improved global positioning system satellite signal acquisition method and device. The method and device of the invention reduces the number of operations in the block correlation used in determining Doppler frequency and time of the received GPS C/A and P(Y) codes. Reducing the number of operations in block correlation increases acquisition speed and reduces energy requirements, aspects conducive to commercial and military hand held GPS receivers.

  • Patent number: 5751238
    Abstract: An apparatus and method for providing small size, high gain corner reflection of radio frequency signals for use in military and commercial applications. Conventional corner reflector practice is combined with electronic amplifying reflection devices such as the superregenerative amplifier to provide an array of antennas and amplifiers spread over each planar surface of a corner reflector. The specific antenna used may be selected from a plurality of various antenna types depending on the application. As in a conventional corner reflector, the amplified signal is reflected at the same angle and in the opposite direction of the incident signal.

  • Patent number: 5369408
    Abstract: This invention is directed to an expendable which includes an electronic circuit for introducing a simulated Doppler frequency shift. When dropped from an aircraft, the expendable is used to confuse hostile radar operations. In the past, the approach has been to use a high frequency electronic switch (PIN diode) and drive oscillator to change the impedance of the expendable antenna. This invention involves a simplification which combines the electronic switch and its drive oscillator into a single semiconductor component. By connecting a feedback circuit from the collector to the base of a high frequency transistor as well as to the two arms of the antenna, the antenna impedance is changed at the transistor oscillating frequency.
