In embodiments, the fastener systems can include a plate having first and second surfaces with an aperture extending between the first surface of the plate and the second surface of the plate and configured to receive a fastener therein. A cover portion is provided to substantially enclose the first end of the aperture so as to cover a head of the fastener received within the aperture and protect the fastener from impacts due to objects striking the roof structure.

Abstract: A low profile brooder is provided, comprising a venturi, a burner base, a burner cap, and a baffle. The burner base and the burner cap reside adjacent to each other, with the burner cap disposed above the burner base and with a distribution chamber between them. A central axis is defined. A venturi resides below the burner base and is in fluid communication with the distribution chamber at the central axis. The venturi defines a fuel flow path between its upstream and downstream ends. The fuel flow path resides at least partially at one or more of an acute angle, a perpendicular angle, and an obtuse angle to the central axis. A baffle resides in the distribution chamber between the central axis and the periphery.

Abstract: A subsea garage for an unmanned underwater vehicle (UUV) has a body having a receptacle for the UUV, an open top providing a transit path for the UUV into and out of the receptacle and a base opposed to the open top, the base being arranged to lie on the seabed. At least one post is movable, subsea, relative to the body into a deployed position extending upwardly from the body above the open top. A lid may also be movable relative to the body between a closed position that closes the open top and an open position that allows the UUV to move along the transit path through the open top. A fixed post may extend upwardly from the body above the open top, in which case the lid may enclose the post when in the closed position and expose the post when in the open position.

Abstract: A radar cloaking apparatus configured for positioning on a radar target and corresponding methods are provided. The radar cloaking apparatus comprises a radio signal emitter and computational circuitry. The computational circuitry is configured to cause the radar cloaking apparatus to at least reference a model encoding scattering properties of the radar target; determine a predicted reflection signature of the radar target from a selected interrogation angle based at least in part on the model encoding the scattering properties of the radar target; and cause transmission, by the radio signal emitter, of a cloaking radio signal along the selected interrogation angle. The cloaking radio signal is actively generated based on the predicted reflection signature of the radar target shifted in phase such that the cloaking radio signal is configured to destructively interfere with a reflected signal formed by an interrogating radar signal scattering off of the radar target.

Abstract: A mounting device includes a first male threaded fastening member such as a lag screw and a second male threaded fastening member such as a bolt. The male threaded fastening members are secured to one another through a joining member such as a bolt and female threaded fastening members such as wingnuts or star knobs. Tightening the female threaded fastening members fixes an angle between the male threaded fastening members without the use of tools. The first male threaded fastening member typically mounts to a tree, a post, or the ground and the second male threaded fastening member typically mounts to a camera or other electronic device. Adapters can secure the mounting device to steel fence posts or step-in posts. An internal spacing device with a flange prevents wear and tear of components of the mounting device.

The system is caused to determine a body-axis lift coefficient based on the plurality of operating parameters, which corresponds to a lift of the aircraft created along a vertical body-axis. The system is also caused to determine a dynamic pressure, which is used to estimate the airspeed parameters.
