Abstract:
Apparatus, methods, and systems provide emitting and negatively-refractive focusing of electromagnetic energy. In some approaches the negatively-refractive focusing includes negatively-refractive focusing from an interior field region with an axial magnification substantially greater than one. In some approaches the negatively-refractive focusing includes negatively-refractive focusing with a transformation medium, where the transformation medium may include an artificially-structured material such as a metamaterial.
Abstract:
A hybrid propulsive technique, comprises providing at least some first thrust associated with a flow of a working fluid through at least a portion of an at least one axial flow jet engine. The hybrid propulsive technique includes extracting energy at least partially in the form of electrical power from the working fluid, and converting at least a portion of the electrical power to torque. The hybrid propulsive technique further includes rotating an at least one substantially axial-flow independently rotatable compressor rotor at least partially responsive to the converting the at least a portion of the electrical power to torque.
Abstract:
Apparatus, methods, and systems provide emitting, field-adjusting, and focusing of electromagnetic energy. In some approaches the field-adjusting includes providing an extended depth of field greater than a nominal depth of field. In some approaches the field-adjusting includes field-adjusting with a transformation medium, where the transformation medium may include an artificially-structured material such as a metamaterial.
Abstract:
According to various embodiments, a mobile device continuously and/or automatically scans a user environment for tags containing non-human-readable data. The mobile device may continuously and/or automatically scan the environment for tags without being specifically directed at a particular tag. The mobile device may be adapted to scan for audio tags, radio frequency tags, and/or image tags. The mobile device may be configured to scan for and identify tags within the user environment that satisfy a user preference. The mobile device may perform an action in response to identifying a tag that satisfies a user preference. The mobile device may be configured to scan for a wide variety of tags, including tags in the form of quick response codes, steganographic content, audio watermarks, audio outside of a human audible range, radio frequency identification tags, long wavelength identification tags, near field communication tags, and/or a Memory Spot device.

Abstract:
Exemplary methods, systems and components enable detection and/or monitoring and/or control of electromagnetic radiation (EMR) exposure of target body-related portions of a user operating a telecommunication device. In some embodiments a risk-assessment output is provided based on a safety threshold or predetermined intrusion level of EMR exposure.
Abstract:
A system and method can include a motor subject to a change in efficiency as a function of temperature and a motor cooling system. The motor cooling system can be driven to minimize the sum of energy consumed by the motor and the cooling system.
Abstract:
A method, composition and system respond to ionizing radiation to adjust biological activity. In some approaches the ionizing radiation is X-ray or extreme ultraviolet radiation that produces luminescent responses that induce biologically active responses.
