    摘要: An acoustic transmission device may communicate sensing data via one or more multiple-input multiple-output (MIMO) transmissions. The device may comprise a serial peripheral interface (SPI) and/or a phase shifting key (PSK) modulator. The device may be configured to provide a first SPI signal, perhaps including one or more coded information bits, to the PSK modulator. The device may provide a second SPI signal, perhaps including a synchronous clock signal, to the PSK modulator. The device may generate of one or more symbols on N transmit branches based on the first SPI signal. The device may generate of at least one carrier frequency with one or more phases to form one or more phased carriers based on the second SPI signal. The device may control a transmission of the sensing data (e.g., video) via the one or more symbols on the N transmit branches on the one or more phased carriers.

    摘要: In one aspect the invention provides a graded refractive index single crystal waveguide having a glass block containing at least one crystal core, the crystal core having a central portion extending along an axis from a first end to a second end; an interface defining a peripheral boundary of the crystal core at a junction of the crystal core and an adjacent portion of the glass block, and a continuous, radially symmetric misorientation transverse to the central portion; wherein the misorientation has a misorientation angle that increases with increasing distance from the central portion towards the interface.

    摘要: The present invention includes methods of promoting single crystal growth via solid-solid transformation of an appropriate glass, while avoiding the gaseous or liquid phase. In certain embodiments, in the all-solid-state glass-to-crystal transformation of the invention, extraneous nucleation is avoided relative to crystal growth via spatially localized laser heating and optional inclusion of a suitable glass former in the composition. The ability to fabricate patterned single-crystal architecture on a glass surface was demonstrated, providing a new class of micro-structured substrate for low cost epitaxial growth and active planar devices, for example.
