Abstract

Claims (59)

1 . A communications system comprising:

a plurality of primary computing devices (“PCD”) each comprising:

a communications device;

a plurality of secondary computing device (“SCD”) each comprising:

a geolocation device that generates geospatial data associated with the SCD;

a unique identifier stored in a data store;

wherein

each PCD and SCD is man-portable;

the plurality of PCDs are configured to form a mesh network utilizing at least one IEEE 802.11x standard;

each PCD is configured to

form, via the communications device, a wireless local area network (LAN) with at least one of the SCDs utilizing at least one second IEEE 802.11x standard;

receive, via the LAN, the geospatial data and the unique identifier from one or more of the SCDs;

transmit, via the communications device, the geospatial data and/or the unique identifier to a command node included in the mesh network for conveyance via a display associated with the command node;

the display comprises a GUI;

the GUI comprises a map;

at least one of the PCD and/or the command node is configured to map the geospatial data and the unique identifier to Earth coordinates in real-time or at predetermined intervals;

at least one PCD comprises an antenna element conductively coupled to the communications device;

the antenna element comprises a conductive composition;

the conductive composition comprises:

a polymer;

fully exfoliated graphene sheets; and

the fully exfoliated single sheets of graphene form a three-dimensional percolated network within the polymer.

2 . The communications system of claim 1 , wherein

each SCD comprises a second communications device communicatively coupled to a second control circuit;

the second communications device comprises a second antenna element;

the second antenna element comprises the conductive composition; and

the second control circuit is configured to establish the wireless LAN.

3 . The communications system of claim 1 , wherein

each of the SCD comprises:

a primary housing;

a secondary housing;

a heatsink;

a thermal dissipation structure;

wherein

the primary housing comprises the secondary housing positioned therein;

the secondary housing comprises

the geolocation device;

the second communication device;

the thermal dissipation structure;

the thermal dissipation structure

laterally and peripherally extends from the secondary housing; and

is thermally coupled to one or more of the second communication device and the geolocation device.

4 . The communications system of claim 3 , wherein

each SCD comprises a thermal dissipation medium;

wherein

the thermal dissipation medium

is thermally coupled to thermal dissipation structure;

is positioned between the primary housing and the secondary housing; and

comprises one or more of a mineral oil, a wax-based phase change material (PCM), a non-paraffin organic PCM, and a hydrated salt PCM.

5 . The communications system of claim 4 , wherein

each SCD comprises a power source; and

the power source is configured to receive electrical power by conductive wireless charging.

6 . The communications system of claim 5 , wherein at least one of the SCD and/or the PCB is man portable.

7 . The communications system of claim 6 , wherein

the SCD comprises an attachment element configured to demountably attach to an apparel item or a baggage item.

8 . The communications system of claim 6 , wherein

the PCD is configured to be worn on the torso of a user.

9 . The communications system of claim 6 , wherein

the geospatial data comprises at least one of latitudinal data, longitudinal data, altitudinal data, and velocity data.
