Abstract: Embodiments of the present invention relate to communications tarpaulins. In one embodiment, the communications tarpaulins include a textile layer, a plurality of antenna elements, and a communications hub. The communications hub includes a plurality of radio frequency (“RF”) connectors. The communications hub is affixed to the textile layer. The RF connectors are each conductively coupled to one of the antenna elements. The RF connectors each demountably receive a communications device. The antenna elements are each affixed to the textile layer and includes a conductive composition. The antenna elements each include a conductive composition. The conductive composition includes a polymer and fully exfoliated single sheets of graphene that are present as a three-dimensional percolated network within the polymer. The textile layer includes a first textile layer and a second textile layer that are coterminous and physically coupled together and thereby form a multilayered structure.

Abstract: Embodiments relate to a sensor node communication system that determines the presence of an object. The system includes man-portable nodes that communicate via a self-organizing LAN. Each node includes a control circuit that has multiple cores, multithreading, and/or parallel processing. The control circuit establishes the LAN, captures an image, determines a presence of a predetermined object in the image using a machine learning algorithm, generates a first notification when presence of the predetermined object is determined, and generates a second notification when the presence is not determined. The control circuit detects an electromagnetic environment, determines unused frequency bands, and adapts a radio working parameter to broadcast in the unused frequency band. Determining the unused frequency bands includes the use of a spectrum sensing method. The control circuit detects an electromagnetic environment, determines unused frequency bands, and adapts a radio working parameter to broadcast in unused frequency bands.

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 relate to a communications node that includes an interfacing plate assembly; an antenna assembly; a board mounting assembly; a housing; and an enclosure. The housing includes the antenna assembly and the board mounting assembly. The enclosure is a rigid, open ended, sleeve structure that selectively receives the housing and thereby encloses the antenna assembly and the board mounting assembly therein. An interfacing plate assembly is positioned at a second end. The interfacing plate includes an input device coupled to the control circuit that receives user operational input. The antenna assembly includes an antenna frame that includes the antenna elements and orients the antenna elements in each nodal cardinal direction. The board mounting assembly includes the communication device and the control circuit that are positioned proximate to a plate. The plate is coupled to the first end opposite the interfacing plate and thermally coupled to the control circuit.
