Abstract: Embodiments of the present invention relate to wearable computing devices. In some embodiments, a wearable computing devices (“WCD”) for monitoring occupational hazards are disclosed. The WCD may include an apparel item having one or more control circuits affixed thereto. One or more sensors may be communicatively coupled to the computing device and configured to detect or monitor at least one of an aspect of a user of the WCD and an ambient environment of the user. The control circuits can be configured to generate one or more notifications when sensor data comprises a value above a threshold amount.

Abstract: Compositions comprising graphene sheets, graphite, at least one binder, a carrier system. About 1 to about 50 weight percent of the carrier system comprises at least one of a cyclic imide and lactone. The graphene sheets consist of fully exfoliated single sheets of graphite. The ratio by weight of graphite to graphene sheets is from about 50:50 to about 85:15. The composition may be used as coatings and inks.

Abstract: Embodiments of the present invention relate to graphene-based Rotman lenses. In an embodiment, a lens is formed on a surface of a dielectric plate. The lens comprises a composition having individual sheets of graphene. The lens includes a plurality of first transmission lines extending from a first lens contour and a plurality of second transmission lines extending from a second lens contour. The plurality of first transmission lines each terminate at a first port. The plurality of second transmission lines each terminate at a second port. The first contour and the second contour are positioned opposite each other. The first port and/or the second port has a width of λ/2 or less. The individual graphene sheets form a three-dimensional interconnected network within the composition.

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.
