Abstract: The present invention relates to a unique multi-purpose towed trailer unit having an aerodynamic streamlined configuration which results in less drag on the towing vehicle-trailer combination compared with drag resulting from the use of a bluff body trailer and a towing vehicle. At rest, the trailer is used in combination with a collapsible self-supporting deployable shelter which is stored in the interior of the trailer.

Abstract: Collapsible portable self-supporting shelter structures having from at least two component quad sections to seven or more component quad sections, which joined end to end form the width of the structure; and, said entire component sections optionally being joined side to side form a desired depth of the portable shelter. The resulting structure is a collapsible self-supporting prefabricated deployable shelter having a clear span interior without supporting columns. Some versions of the collapsible portable self-supporting shelter structure due to its configuration may optionally contain a floating hub which is a top element extending above the structure's standard exterior matrix frame. The floating hub forms a high pitch atop the shelter, which high pitch causes the fabric, which covers the matrix frame, to be maintained in a taut downward-sloping condition over the shelter top surface so no rain or snow collects in the fabric at the top of the shelter.

Abstract: A foldable carrying medical pack made of flexible material, adapted to store medical emergency supplies and equipment. Clear storage pouches which contain the medical supplies and equipment are attached by Velcro, for easy removal, to the interior side of the medical pack. This arrangement allows for immediate visible access to every item stored in each pouch/compartment. Each pouch has a clear sewn-in compartment in the front of same, to insert labels therein providing a list of the contents. The label is inserted in the compartment to allow the contents of the pouch to be easily determined. The removable pouches can be replaced with additional pouches that contain medical supplies or equipment oriented toward a variety of different medical emergencies.

Abstract: A double tang articulating hub assembly used in combination with a collapsible self-supporting structure. The double tang articulating hub assembly is used as a connector among tubular rod elements which together provide a generally tubular frame matrix used to erect a collapsible self-supporting prefabricated deployable structure where a clear span interior without supporting columns is required. The hub employs a plurality of one piece “forked plugs” each containing a cylindrical plug with two tangs and an integral post connecting the tangs allowing the forked plug to rotate.
