  • Patent number: 11852211
    Abstract: A 3D printed additively manufactured (AM) elliptical bifurcating torsion flexure assembly system includes a base section; elliptical bifurcating torsion springs, each including a bifurcated legs section supported by the base; a bifurcated elliptical torsion spring section contiguous with the bifurcated legs section; and a single upper section contiguous with the elliptical torsion spring section. The single upper section includes a connection component, and the device material includes Hot Isostatic Pressing (HIP) heat-treated Ti6Al4V. The elliptical bifurcating torsion flexure assembly is printed as one part by a 3D additive manufacturing process, and the bifurcation maintains consistent balance while being torqued. The stiffness-spring rate of the device is at least partly controlled by varying cross-sectional shape and diameters by the 3D additive manufacturing printing.

  • Publication number: 20230408630
    Abstract: A Simultaneous Transmit and Receive (STaR) system utilizing high power transmitters and high sensitivity receivers in conjunction with one or more signal polarizers to maintain far-field polarization efficiency for both transmission and reception of same (or similar) frequency content at the same time. This STaR system maintains far-field polarization efficiency to remote target(s) while simultaneously introducing a near-field polarization mismatch between the transmission and receiver subsystems for higher isolation and reduced coupling.

  • Patent number: 11815682
    Abstract: A combiner assembly for a ceiling mounted projection head up display system for an aircraft cabin has an optical combiner (10), and a support mechanism (30, 32, 35) for supporting the optical combiner to be movable between an operational position and a stowage position, above the user, and laterally displaced, and facing an underside of the projector assembly by means of a lateral component of movement and a rotation component to reach the stowage position under the projector assembly (20). Such a two axis movement can make better use of limited headroom in cabins such as those of small aircraft, by enabling a stowage location offset to one side of the line of sight, while providing sufficient clearance from the user's head and from cabin structure, during the movement and/or when in the storage position.

  • Patent number: 11815335
    Abstract: Systems are disclosed for navigating a missile to a target using a fixed sensor onboard the missile. In an embodiment, a system includes a launch platform traveling a pre-programmed route to deliver the missile within an area. The missile travels a first flight path through the area in effort to detect targets. If no targets are detected along the first flight path, the missile transitions to a second flight path, different from the first flight path, to locate targets off-axis relative to the first flight path. While the missile travels the second flight path, the sensor receives signal identifying a target located at a position off-axis relative to the first flight path. The missile then adjusts the second flight path to direct the missile to the target. In an example embodiment, the first flight path is straight or arced, while the second flight path is u-shaped, corkscrew-shaped, or spiral-shaped.
