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: A wearable apparatus includes an antenna affixed to a surface of the apparatus. A device is conductively coupled to the antenna. A control circuit is communicatively coupled to a sensor, the device and, a communications device. The antenna includes a composition that includes a polymer and carbonaceous material made up of individual graphene sheets that are present in the polymer in a 3D percolated network. A mobile device is communicatively coupled to a cellular RF source via a first wireless signal. The control circuit is configured to communicate with the mobile device via a third RF signal; communicate with the RF source via a second RF signal; and cause the mobile device to communicate with the RF source via the third RF signal when the second RF signal is greater than the first RF signal.

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: A wearable apparatus includes an antenna affixed to a surface of the apparatus. A device is in electrical communication with the antenna. A control circuit is in electrical communication with the device and a communications device. The antenna comprises a composition comprising carbonaceous material consisting of individual graphene sheets. The individual graphene sheets are present in the composition in a continuous three-dimensional connected network where individual graphene sheets have nanometer scale separation at contact points between individual graphene sheets. The control circuit is configured to (i) communicate, using the communications device, with a mobile device via a first radio frequency (“RF”) signal; and (ii) communicate, using the device, with a cellular tower via a second RF signal. The signal strength of the first RF is greater than the signal strength of the second RF signal. The first RF signal utilizes an IEEE 802 standard for data transmissions.
