Abstract: Embodiments relate to a RF localization system that determines the position of a RF source of interest (RFSOI) relative to the RFLS. The RFLS includes man-portable nodes that communicate via a self-organizing WAN. Each node includes a communications device conductively coupled to antenna elements oriented in each nodal cardinal direction and battery each communicatively coupled to a control circuit(s). The control circuit is configured to: establish the WAN; capture RSSI values for each antenna element; determine the position of the RFSOI relative to the node; when not functioning as a primary node, transmit the determined position to a primary node or a computing device that's external to the WAN for processing; and when functioning as a primary node, determine the relative position of the RFSOI relative to the plurality of nodes using the received determined position. The primary node determines the position of the RFSOI relative to the nodes.

Abstract: Embodiments of the present instant disclosure relate to a puncture resistant sole for a footwear article. The puncture resistant sole includes an insole and outsole. The outsole includes a formation of cleat protrusions and first polymer composition. The cleat protrusions includes a second polymer composition and are removable. The first polymer composition and the second polymer composition each includes graphene sheets dispersed therein. The graphene sheets includes an X-ray diffraction pattern displaying no signature corresponding to graphite or graphite oxide. The insole includes a third polymer composition that includes the graphene sheets dispersed therein. The graphene sheets include an oxygen-containing functional group. The first polymer composition, second polymer composition, and/or third polymer composition includes a tensile strength of 50 lbs. per square inch or greater. The first polymer composition, second polymer composition, and/or third polymer composition comprises a thermal insulation value of at least 0.12 clo.

Abstract: Embodiments of the present invention relate to graphene-based Rotman lenses. In an embodiment, a lens is formed on a surface of a dielectric plate. The lens comprises a composition having individual sheets of graphene. The lens includes a plurality of first transmission lines extending from a first lens contour and a plurality of second transmission lines extending from a second lens contour. The plurality of first transmission lines each terminate at a first port. The plurality of second transmission lines each terminate at a second port. The first contour and the second contour are positioned opposite each other. The first port and/or the second port has a width of λ/2 or less. The individual graphene sheets form a three-dimensional interconnected network within the composition.
