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 of the instant disclosure relate to portable radio mounting apparatus (PRMA). The PRMA includes a main body, landing pad, antenna element(s), RF connector conductively coupled to the antenna element, retaining element and has “open” and “closed” states. Landing pad laterally extends from the main body and includes the antenna element(s) and a first end pivotably coupled to main body. RF connector is conductively coupled to the antenna element. In the open state, the landing pad is pivoted away from the main body and thereby exposes the retaining element; the retaining element receives a portable radio and thereby demountably secures the portable radio to the main body; and the RF connector demountably and conductively couples to the portable radio. In the close state, landing pad is pivoted towards the main body and wrapped around the portable; and is demountably coupled to the main body.
