Abstract: Methods, devices, and systems are described for a mounting flange and bracket for a space habitat. The bracket system couples a bladder of a space habitat to a cylindrical core. The bracket system includes a soft goods layer configured to cover the bladder of the space habitat. The bracket system includes a mounting flange configured to couple at an end of the cylindrical core. The mounting flange includes a lip extending around the mounting flange. The bracket system includes a bracket configured to connect the soft goods layer to the mounting flange. The bracket has a first end and a second end. The first end includes a pin configured to couple to the soft goods layer. The second end includes a protrusion configured to latch to the lip of the mounting flange. In some variations, a cap is configured to be coupled to the outer side of the mounting flange.

Abstract: Methods, devices, and systems are described for a bracket fixture for securing a load to a soft goods layer in a space habitat. The bracket fixture includes a base having a plurality of sides, the plurality of sides having a pin parallel to its respective side, and an aperture between the pin and the respective side. The bracket fixture further includes a protrusion extending from the base, the protrusion including a fixture element.

Abstract: A system (10) for providing a stream of water that includes a surfactant, comprising a source (14) of water, means (32) to cause water to flow along a water supply duct (34), and a venturi injector (36) within the water supply duct. The venturi injector (36) communicates with an inlet duct (77) to supply surfactant; and the system comprises a surfactant supply duct (80, 83) that communicates between the inlet duct (77) and a surfactant container (18), the surfactant supply duct comprising a first portion that incorporates an on/off valve (38) and a second portion (83) that incorporates a check valve (84) to control flow. A plurality of surfactant containers (18) may be connected to the inlet duct (77) in this way; and each surfactant container 18 may be mounted within an open-topped chamber (68) to which hot water may be provided to heat the contents of the surfactant container (18).

Abstract: A novel design and construction method for the creation of a deployable flexible flood mitigation wall manufactured from textile and membrane materials. The flexible flood mitigation wall system comprises a textile/membrane wall and support posts configured to be movable between a stowed position and a deployed position and wherein, in the deployed position, the wall forms a leak-free barrier against flood water or other fluids. A series of posts that are manually deployed is used to support the fabric wall when hydrostatically challenged, and transfer loads to the ground. The wall is stored at the point of use in a surface box or trench box and keeps the loading from the flood water off the building, structure or equipment being protected.

Abstract: A link arm (81) for restraining lateral movement of a pivotable vehicle suspension system (1), wherein a first end (90) of the arm (81) is pivotally connected to a wheel-mounting end of the system (1) and a second end (91) of the arm (81) is pivotally mounted to a frame of the vehicle such that the arm (81) may pivot relative to the frame in unison with the wheel-mounting end and restrain lateral movement of the system (1) relative to the frame. The first end (90) has a bearing (90) through which a pivot pin (71) extends. The second end (91) has a ball and socket joint 91 (ball joint) enabling pivoting of the arm (81) relative to the frame about more than one axis.

Abstract: A contact opening through an insulating layer is filled with metal and etched back to form a metal plug within the opening. A metal interconnect line can then be formed over the contact, and makes electrical contact with the metal plug. Since the contact opening is filled by the metal plug, it is not necessary for the metal signal line to have a widened portion in order to ensure enclosure.

Abstract: A loudspeaker system includes an upper frequency assembly that radiates acoustical energy having spectral components in the audio frequency range above a predetermined upper frequency, typically at the high end of the bass frequency range between 150 and 200 Hz. The assembly includes a ported enclosure with a front face enclosing a loudspeaker driver with a cone adjacent to the front face of diameter slightly less than at least one of the height and width of the enclosure.

Abstract: An antenna system is comprised of a plurality of independently constructed and operated antenna units, upon which are mounted a plurality of transmit and receive antenna pairs. This structure provides a means for the antenna system to be arranged to provide substantially hemispherical radio coverage. By adjusting the phase of each version of a radio signal to the transmitter or received, the signal may be formed into a beam according to known techniques of directional beam forming providing the antenna system with directional gain. Additionally, using a plurality of transmit and receive antenna pairs reduces the energy transmitted by each transmit antenna alone to a level which permits a branch line coupler to be sufficient to orthogonally polarize the transmitted and received radio signals negating the requirement for the duplexing filter for duplex operation.
