Abstract:
A photonic crystal is configured with wavelength converting material to act as a concentrator for electromagnetic energy. The concentrator may also be configured with energy conversion devices to convert the electromagnetic energy into another form of energy.
Abstract:
An electromagnetically responsive element includes an arrangement of self-resonant bodies, such as atoms or quantum dots that form an effective dielectric constant, typically at or near a resonance.
Abstract:
Artificial materials, such as metamaterials, include adjustable properties. In some approaches the properties are adjustable according to active feedback of interaction with electromagnetic waves.
Abstract:
A method and system are described for establishing one or more reference time values indicative of a systemic flow of one or more markers to an outgrowth and indicating one or more event time values partly based on a signal from the outgrowth and partly based on the one or more reference time values.
Abstract:
Bone cages are disclosed including devices for biocompatible implantation. The structures of bone are useful for providing living cells and tissues as well as biologically active molecules to subjects.

Abstract:
An optical device includes an interface between two or more media. The refractive indices, orientations of media, and alignment relative to a propagating wave define a refractive boundary at which reflections may be reduced or eliminated, and at which, for certain incident angles, rays may be refracted on the same side of the normal as the incident ray.
Abstract:
Embodiments of a lumenally-active system and method of use and control thereof are disclosed. According to various embodiments, a lumenally-active device is positioned in a body lumen of an organism, where the device may sense a parameter of a fluid in the body lumen and perform an action on the fluid. Control logic and/or circuitry may be located on the device, or the system may include a separate control module. Liquid or gaseous fluids may be treated by embodiments of the device. Actions may include, for example, modification of a body fluid by addition or removal of a material, or by modification of a property of a body fluid or a component thereof.
