Abstract: The embodiments relate to systems and methods for wavefront error (WFE) correction of a conformal optical component using a planar lens. The embodiments include a conformal optical component transmissive to electromagnetic radiation (EMR), which is propagated through the conformal optical component along a path axis. The conformal optical component is rotationally asymmetric about the path axis. A planar corrector lens is configured to correct a WFE of the conformal optical component. The planar corrector lens defines a lens axis. Accordingly, use of a single planar corrector lens for WFE correction of a conformal optical component reduces bulk and manufacturing complexity.

Abstract: The embodiments relate to a conformal, sometimes referred to as aerodynamic, nose cone, and in particular to a hollow conformal nose cone that is transparent to electromagnetic radiation of a predetermined wavelength, or wavelengths, and that comprises a variable thickness such that the electromagnetic radiation received on an outer surface of the nose cone forms a predetermined beam pattern within the nose cone. Also disclosed are mechanisms for generating such hollow conformal nose cones.

Abstract: A method for making a downhole electrical feedthrough package where the feedthrough package may include a metal shell forming a shell conduit. A metal web may be coupled to the metal shell, and the metal web may form a web conduit. A conducting pin may extend through the shell conduit and web conduit. A dielectric seal may electrically isolate the conducting pin from the metal web. The dielectric seal may be formed by a bismuth glass based dielectric sealing material system having at least two of the four components selected from Bi2O3, B2O3, MO, and optionally REO forming a bismuth glass system. MO may be selected from ZnO, BaO, TiO2, and Fe2O3, and their glass making pre-cursors. REO may be selected from CeO2, Y2O3, Sc2O3, Nd2O3, Pr2O3, and lanthanum series oxides. One or more isolators may be disposed within the shell conduit proximate to the dielectric seal and surrounding a portion of the conducting pin.

Abstract: A detachable tee-top includes a framework having base portions fastened to two opposed sides of a center console of a boat and consisting of elongated tubes having fasteners fastened to the center console by threaded fasteners. The framework includes a further elongated tube for each of the elongated tubes making up the base portions with each of the further elongated tubes being sized to be slidably receivable within the upwardly facing opening of a respective one of the base portion elongated tubes. Thus, the further elongated tubes or pipes may easily be removed from the base portion elongated tubes when it is desired to remove the detachable tee-top from the associated vessel. The tee-top also includes a horizontally oriented support frame for a cover. Flexible straps attached to this support frame are stretched downwardly and attached to the base portions of the device to support the frame in high wind conditions. The framework is disclosed in two alternative configurations of elongated tubes.
