    摘要: A system and method for managing access to a satellite-based transponder by a plurality of aircraft each having a mobile radio frequency (RF) system. The system employs a ground-based, central control system for managing access to the satellite-based transponder so that the aggregate power spectral density (PSD) of the RF signals of all the mobile systems does not exceed, at any time, limits established by regulatory agencies to prevent interference between satellite systems. This is accomplished by a dual control loop arrangement for monitoring the signal-to-noise ratio (Eb/No) of the RF signal transmitted by the satellite-based transponder. A ground-based control loop is used whereby a ground-based central controller monitors the Eb/No and transmits commands to the aircraft (via the satellite transponder) to maintain the Eb/No of the transmitted signal within a predetermined range. A fast scan angle compensation is used by the mobile system of the aircraft to implement another control loop to further adjust the transmit power. This control loop maintains the Eb/No of the signal transmitted to the satellite-based transponder at the commanded level inbetween updates from the ground-based central controller.

    摘要: Provided are computer-implemented methods and systems used in assuring a person's identity that include the steps of receiving from the person one or more identifying statements and receiving from the person authorization to access one or more identity sources on which the person is registered. Data is then extracted from one or more of the identity sources to corroborate the one or more identifying statements, and the data aggregated to provide first and second scores, the first score representing factors that tend to affirm the person's identifying statements and the second score representing factors that tend to disaffirm the person's identifying statements. Optionally, the scores are displayed in a graphical user interface.

    摘要: A connector comprises a body having a passage therethrough for fluid flow and a female portion for receiving by a slip fit a tubular member. Gripping means are placed in the passage in the female portion for gripping the tubular member and is configured for preventing the tubular member from rotating. A retainer retains the gripping means in place and a seal prevents leakage.

    摘要: A method and apparatus for estimating a lever arm correction between the wide beam antenna and the spot beam antenna in a navigational satellite system is disclosed. A prescribed satellite maneuver is used to increase the accuracy of the predicted satellite attitude in determining the lever arm, and lever arm corrections are provided to navigation receivers using curve fit coefficients to permit long range estimates and to minimize data transmission requirements.

    摘要: A method for forming a metal carbide layer begins with providing a substrate, an organometallic precursor material, at least one doping agent such as nitrogen, and a plasma such as a hydrogen plasma. The substrate is placed within a reaction chamber; and heated. A process cycle is then performed, where the process cycle includes pulsing the organometallic precursor material into the reaction chamber, pulsing the doping agent into the reaction chamber, and pulsing the plasma into the reaction chamber, such that the organometallic precursor material, the doping agent, and the plasma react at the surface of the substrate to form a metal carbide layer. The process cycles can be repeated and varied to form a graded metal carbide layer.

    摘要: A measurement unit comprising a light source and a photodetector may be formed in a cavity in a substrate. The light source produces light that impinges a material layer and is reflected back to the photodetector. Through methods such as interferometry and ellipsometry, the thickness of the material layer may be calculated from the light intensity data measured by the photodetector. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
