    摘要： An apparatus in one example comprises a first proofmass employable to sense a first acceleration along a first input axis; a second proofmass employable to sense a second acceleration along a second input axis; and a third proofmass employable to sense a third acceleration along a third input axis. The first input axis, the second input axis, and the third input axis arc substantially orthogonal. The first proofmass, the second proofmass, and the third proofmass are substantially coplanar.

    摘要： The disclosure generally relates to a method and apparatus for providing high-speed, low signal power amplification. In an exemplary embodiment, the disclosure relates to a method for providing a wideband amplification of a signal by forming a first transmission line in parallel with a second transmission line, each of the first transmission line and the second transmission line having a plurality of superconducting transmission elements, each transmission line having a transmission line delay; interposing a plurality of amplification stages between the first transmission line and the second transmission line, each amplification stage having an resonant circuit with a resonant circuit delay; and substantially matching the resonant circuit delay for at least one of the plurality of amplification stages with the transmission line delay of at least one of the superconducting transmission lines.

    摘要： The present invention relates to a binary translator for directly translating binary instructions written for a legacy processor to executable binary instructions for a native processor. In accordance with an important aspect of the invention the binary translator is configured as a reconfigurable translator, which enables the binary translator to be used with different legacy processors and/or operating systems and native processors. The binary translators also optimize to take advantage of more efficient native processor instructions and allows portions of the legacy binary code to be disabled and/or new native instructions to be added to the application program without modification of the legacy binary code.

    摘要： An exemplary navigation system uses a master navigation component at a first location with a first sensor in a vehicle and a slave navigation component with a second sensor at a second location that is a variable displacement to the first location due to physical deformation of the vehicle. Static and dynamic location components provide static and dynamic information of the displacement between the first and second locations. A flexural model based on the deformation characteristics calculates the dynamic displacement. An error estimator estimates errors in the navigation measurement data of the slave navigation component based on the displacement information. The master navigational component corrects the navigation measurement data of the slave navigation component based on the determined error, translates the corrected navigation measurement data of the slave navigation component into navigation measurement data in its coordinate system, and combines the output of the second sensor based on the corrected navigation measurement data with the output of the first sensor into a combined result.

    摘要： Embodiments of the present system encompass: a hemispherical resonator gyro (HRG); digital control loop algorithms which operate in two, distinct modes, Force to Rebalance (FTR) and Whole Angle (WA); and a closed-loop slewing-voltage phase control that reduces quadrature error when the hemispherical resonator gyro transitions from WA to FTR.
