Abstract: A check valve having a through-flow grooved poppet is provided in which the poppet includes a plurality of helically-oriented grooves around the exterior surface of the poppet, as well as a set of poppet apertures. When the check valve is displaced from a closed position, fluid flows from a first port to a second port by passing through both the set of poppet apertures and the plurality of helically-oriented groves positioned on the exterior of the poppet. The poppet thus provides multiple flow paths which improves the performance of the check valve by reducing the pressure drop upon activation.

Abstract: A sonar display comprises a processing element and a display. The processing element is configured to receive a first sonar electronic signal from a first sonar transducer, receive a second sonar electronic signal from a second sonar transducer, generate data for a first underwater image stream from the first sonar electronic signal and a second underwater image stream from the second sonar electronic signal. The display is configured to show at least one of the first underwater image stream having a first view derived from reflections of a first sonar beam, the second underwater image stream having a second view derived from reflections of a second sonar beam, and an indication of a position of the first sonar beam relative to the second sonar beam.

Abstract: A marine sonar display device comprises a display, a sonar element, a memory element, and a processing element. The display presents sonar images. The sonar element generates a sonar beam and presents transducer signals. The processing element is in communication with the display, the sonar element, and the memory element and receives the transducer signals, calculates sonar data from the transducer signals and generates a three-dimensional view of a portion of the body of water, wherein the view includes a plurality of sonar images. Each sonar image is generated from sonar data derived from a previously-generated sonar beam and includes representations of underwater objects and a water bed. The processing element also generates a cursor plane and a cursor positioned thereon, both of which appear on the three-dimensional view. The processing element further controls the display to present the three-dimensional view, the sonar images, the cursor plane, and the cursor.

Abstract: A satellite recovery apparatus having a base configured to be attached to a satellite and having a pressurized gas chamber and a valve assembly. A plurality of walls are hingedly attached to the base and movable between a closed position, wherein the walls define a volume above the base, and an open position, wherein the walls are disposed spaced away from the base. A heat shield is attached to the base. A deployable decelerator is attached to the heat shield and has an outer perimeter with an expandable torus that is operably connected to the valve assembly such that the expandable torus can be pressurized from the chamber. Pressurization of the expandable torus deploys the decelerator assembly from a non-deployed position within the volume to a deployed high-drag position.
