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 systems and methods to enable communication between computing devices. The system comprises a cellular-based RF source. A mobile computing device(s) is communicatively coupled to the RF source via a first wireless signal received thereby at a first signal strength. An antenna(s) is positioned proximate to the surface of a wearable item and comprises a conductor element(s) fabricated using a polymer(s) and fully exfoliated graphene sheets. A control circuit(s) is positioned proximate to the surface and in communication with the antenna. The control circuit communicates, via the antenna, with the RF source via a second wireless signal; communicates, via a second antenna, with the mobile device via a third wireless; and cause the mobile device to communicate with the RF source via the third wireless signal when it's strength is greater than the first wireless signal.

Abstract: Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders may employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system can establish mesh networking communications and communicatively couple to portable radios via a communications device. Some of the antenna elements may be within the communications suspenders. A plurality of straps are pivotably coupled to an intermediate portion at one end and a demountable fastener at the other end that couples to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps may include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements may be formed using a conductive composition that includes fully exfoliated graphene sheets present as a percolated network in a polymer matrix.

Abstract: A modular communications system having dynamically positionable non-metallic antenna elements is disclosed. The system includes an apparel item with a surface and a foam layer positioned therein. Landing pads are each uniquely positioned on the surface. Antenna elements are coupled to the landing pads; include a non-metallic conductive composition and a unique operational frequency. A hub is positioned on the surface and coupled to each landing pad. Communications devices are demountably affixed to the surface; coupled to the hub; and each include a unique operational frequency. The hub couples each communications devices to a unique landing pad. The foam layer is lined with a conductive material that reflects RF radiation that emanates from the plurality of non-metallic antenna elements. The system achieves an omnidirectional RF radiation pattern when utilizing the plurality of antenna elements and an altered RF radiation pattern when utilizing a subset of the plurality of antenna elements.

Abstract: Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system communicatively couples to portable radios that operate on different RF frequencies via a communications hub. Some of the antennas elements are dynamically positionable (i.e., swappable, switchable, etc.) on the communications suspenders. A plurality of straps are pivotably coupled to an intermediate portion at one end and a demountable fastener at the other end. The demountable fasteners couple to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements are formed using a conductive composition of fully exfoliated graphene sheets present as a percolated network in a polymer matrix.
