    Abstract: Embodiments of the present invention relate to transponder fabrication. In an embodiment, a plurality of antenna elements is applied to a first substrate at a first pitch. A plurality of fully functioning first transponders is positioned on to the first substrate in a manner to each be in electrical communication with an antenna element included in the plurality of antenna elements and thereby forms a plurality of fully functioning second transponders. The plurality of fully functioning first transponders are positioned on a second substrate at a second pitch. The plurality of fully functioning first transponders have a first read range. Second transponders have an increased read range relative to second transponders. The second pitch is greater than the first pitch.

    Abstract: Embodiments of the present invention relate to graphene-based capacitive sensors. In one embodiment, a touch sensor comprises a non-porous insulating substrate having a first side and a second side. A first conductive material is at least partially in communication with the first side. A second conductive material is at least partially in communication with the first side. A third conductive material is at least partially in communication with the second side. The first conductive material and the second conductive material are in communication. The first conductive material forms a linearization pattern. The first conductive material includes a metal. The second conductive material and/or third conductive material comprise graphene sheets.

    Abstract: A communications node includes an apparel item in the form of a shoulder belt that includes an open state, closed state, and main body. A first portion curvingly extends from the main body. A second portion angularly extends from the main body opposite the first portion. A primary fastener demountably couples the first and second portions together when in the closed state. An antenna element and communications device are positioned within the apparel item. An hub is affixed to the apparel item and configured to receive audio/video input. A battery is positioned adjacent to the apparel item. A control circuit is positioned within the apparel item and coupled to the antenna element, hub, communications device, and battery. The control circuit establishes a self-organizing WAN with a plurality of computing devices each directly, dynamically, and non-hierarchically connected to the WAN; and communicates with the computing devices using the self-organizing WAN.

    Abstract: Embodiments of the present invention relate to microphones diaphragms. In one embodiment, a sensor comprising a diaphragm comprised of a composition having a plurality of individual graphene sheets. An emitter formed in a manner to transmit lights towards a surface of the diaphragm. A collector that captures at least a portion of light that is reflected by the diaphragm. A converter is in communication with the detector that converts a signal that is generated by the sensor to a digital signal for processing. The graphene-based composition includes graphene sheets.

    Abstract: A transponder comprises a first polymer layer. A radio frequency (“RF”) transponder is affixed to the first polymer layer, wherein the RF transponder includes a processor in electrical communication with a graphene-based antenna. A second polymer layer is formed on the first polymer layer and the RF transponder. The first polymer layer and second polymer layer form an encasement around the RF transponder. The encasement has a hermeticity of about 10−7 to about 10−12 atm·cc/sec. The encasement provides improved impact, temperature, vibration, chemical, and/or corrosion protection to the RF transponder.
