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.

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.
