Soft-to-hard goods connections with dynamic energy dissipation
A soft-to-hard goods connector is provided which includes an elastomeric bladder having a preform layer and an outer textile layer enclosing the preform layer. The outer textile layer has at least one skin extension layer extending beyond a periphery of the elastomeric bladder. The skin extension layer has a chord attached at a distal end with the chord being perpendicular to the skin extension layer. The connector includes a host rigid structure with a receiving component. The receiving component has a mounting track with the chord mounted in the mounting track. The receiving component permits the chord to rotate about a longitudinal axis of the chord with a limited range of motion.

PNEUMATIC STRUCTURAL ELEMENT
The pneumatic support has a pneumatic body which can be placed pneumatically under pressure and which, under operating pressure, operationally keeps at a distance apart a compression member which extends substantially over its length and a tension member which likewise extends substantially over its length, wherein forces are introduced at force introduction points in end regions of the compression member and the tension member into said members and wherein connecting elements are provided between the compression member and the tension member and introduce forces into the compression member and the tension member likewise at force introduction points, wherein, furthermore, the pneumatic body has formations which extend between adjacent force introduction points and which project outwardly beyond a rectilinear connection between the adjacent force introduction points. As a result, undesired distortion of the support under operating pressure, but without operating load, is avoided.

MOBILE PONTOON AND FERRY CROSSING EQUIPMENT, A PONTOON AND A FERRY ACCOMPANYING THIS EQUIPMENT
Mobile pontoon and ferry crossing equipment as well as a pontoon and a ferry accompanying this equipment, whereas crossing equipment comprises at least one foldable ferry or one foldable pontoon, each of which has a compact modular design composed of float modules and equipped with self-aligned joining elements that stabilized these modules, according to the invention is characterized by the fact that the foldable ferry (1) or foldable pontoon (2) in its closed condition for transportation forms a semi-trailer or a trailer, whose self-supporting chassis (3) is at the same time a basic float module of the foldable ferry (1) or foldable pontoon (2) respectively.
Mobile crossing structure
A movable and dynamic work after construction linking two points separated by a natural or man-made obstacle, allows the permanent crossing of this obstacle. The work includes a deformable apron (1) which extends between said two points. The work comprises a set of elongated elements (2, 3). An assembly of several pairs of elements (2, 3) is disposed along the apron (1). The work comprises drive means (8) disposed at one end or at both ends of said work for adjusting the apron (1) lengthwise. The drive means (8) are arranged so that, when the means (8) are actuated, they drive the assembly of the pairs of elements (2, 3), so as to bulge the central portion of the apron (1) when the means (8) are actuated.
Dock installation apparatus and method
A method of installing a dock includes providing first and second dock sections, each having a bottom transport member, and a dock support that supports the dock section when installed. The first dock section is installed adjacent to a shoreline. The dock lifting device of a dock cart is attached to the second dock section and the lifting device of the dock cart lifts the first end of the second dock section such that the second dock section is supported by the bottom transport member and the cart transport member. The cart moves the second dock section along the first dock section until the first end of the second dock section is adjacent to the second end of the first dock section. The lifting device then lowers the first end of the second dock section to be level with the second end of the first dock section.
