    Abstract: Embodiments of the present invention relate to graphene-based microphone diaphragms. In one embodiment, a acoustic wave sensor comprises a diaphragm comprised of a graphene-based composition, wherein the diaphragm has a first side at least partially covered with a reflective material. An emitter fiber is positioned proximate to the diaphragm, wherein the emitter fiber transmits light towards the first side. A collector fiber is positioned proximate to the diaphragm, wherein the collector fiber captures at least a portion of light reflected by the first side, wherein the collector fiber is in communication with a detector. A converter is in communication with the detector and converts a signal received by the detector to a digital signal for processing. The portion of light that is captured as a result of diaphragm distortion is different than the portion of light captured in the absence of diaphragm distortion. The graphene-based composition includes graphene sheets.

    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: The present invention relates generally to transmission lines and specifically to textile transmission line assemblies. The textile transmission line assemblies are capable of lateral bending, axial rotation, and stretching without suffering from a statistically significant loss of its performance characteristics. Antenna elements are incorporated with the textile transmission line assemblies (hereinafter “combination assemblies”). The textile transmission line assemblies can be incorporated in to garments, apparel items, bags, tents, or other textile-based objects. The textile transmission line assemblies are configured to be flexibly affixed to textile items. The textile transmission line assemblies are impact resistant. Wearable communications systems that incorporate at least one textile transmission line assembly and/or combination assembly are also disclosed.

    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.

    Abstract: Embodiments of the present invention relate to ascertaining the operational fitness of mechanical systems. In an embodiment, a MS facing (“MSF”) detector is positioned proximate to the MS in a manner to detect acoustic pressure (“AP”) emanating from the MS. A computing device is in electrical communication with the MSF detector that correlates detected AP with the MS's operational profile and generates a notification when the correlated data exceeds a predetermined threshold by a predetermined percentage. The computing device transmits the generated notification to a user-facing display.
