  • Publication number: 20190149392
    Abstract: A system and method include a modulator configured to combine satellite codes with carrier signals on an in-phase channel and a quadrature-phase channel to produce I-channel and Q-channel signal components. The powers of the combined satellite codes are selected according to desired code power fractions. A processor pre-distorts the signal components such that they can be transmitted as a unit-amplitude constant envelope transmission that preserves the desired code power fractions. The pre-distortion may also account for data filtering effects that tend to distort the code power fractions.

  • Publication number: 20190143364
    Abstract: A method of applying a sealant material to a corner joint, formed by a first planar surface and a second planar surface, comprises positioning a sealant-applicator tip relative to the corner joint such that a first planar face of the sealant-applicator tip is in flush surface contact with and parallel to one of the first planar surface or the second planar surface and a second planar face of the sealant-applicator tip is in flush contact with and parallel to another one of the first planar surface or the second planar surface. The method further comprises advancing the sealant-applicator tip in a first direction along the corner joint while supplying the sealant material to the corner joint through a channel of the sealant-applicator tip and shaping the sealant material, supplied to the corner joint, with a seventh edge of the sealant-applicator tip to form a first bead of the sealant material.

  • Publication number: 20190145909
    Abstract: An automated high-speed method for inspecting metal around fasteners and a computer-controlled apparatus for performing that inspection method. The apparatus comprises a multi-motion inspection head mounted on a scanning bridge, a robotic arm, or a robotic crawler vehicle. The multi-motion inspection head comprises a millimeter waveguide probe and a motorized multi-stage probe placement head that is operable for displacing the waveguide probe along X, Y and Z axes to achieve multiple sequenced motions. The waveguide probe is attached to a mandrel that is rotatably coupled to an X-axis (or Y-axis) stage for rotation about the Z axis. Smart servo or stepper motors with feedback control are used to move the waveguide probe into place and then scan across or around a fastener head to inspect for cracks that may be under paint.

  • Publication number: 20190145481
    Abstract: Methods of damping vibrations in a host structure are described. In one embodiment, the vibrations can be damped using a tuned mass damper. The tuned mass damper can include a suspended mass with magnets which is configured to move in response to current being applied to a voice coil. The tuned mass damper can damp vibrations resulting from an external load applied to the host structure, such as an external aerodynamic load. In one embodiment, the tuned mass damper can be mounted within a wind tunnel model undergoing transonic testing. The tuned mass damper can be operated to limit potentially destructive vibrations which can occur during testing.
