    Abstract: Enhancing the recovery of unconventional and conventional hydrocarbons is possible by utilizing patterns of wells and hydraulic fractures that are carefully designed to avoid interconnection between injection and production well fractures to allow for both primary production and improved secondary production. Adjacent horizontal wells may be drilled and fractured, with selected wells converted to injection wells after primary production to produce alternating production and injection fractures. In addition, infill horizontal injection wells may be drilled and fractured adjacent to an existing and previously produced multiple transverse fracture horizontal hydrocarbon production well to produce alternating production and injection fractures.

    Abstract: According to some embodiments, the present invention provides a novel photovoltaic solar cell system from photovoltaic modules that are vertically arrayed in a stack format using thin film semiconductors selected from among organic and inorganic thin film semiconductors. The stack cells may be cells that are produced in a planar manner, then vertically oriented in an angular form, also termed herein tilted, to maximize the light capturing aspects. The use of a stack configuration system as described herein allows for the use of a variety of electrode materials, such as transparent materials or semitransparent metals. Light concentration can be achieved by using fresnel lens, parabolic mirrors or derivatives of such structures. The light capturing can be controlled by being reflected back and forth in the photovoltaic system until significant quantities of the resonant light is absorbed. Light that passes to the very end and can be reflected back through the device by beveling or capping the end of the device with a different refractive index material, or alternatively using a reflective surface. The contacting between stacked cells can be done in series or parallel. According to some embodiments, the present invention uses a concentrator architecture where the light is channeled into the cells that contain thermal fluid channels (using a transparent fluid such as water) to absorb and hence reduce the thermal energy generation.

    Abstract: Methods and systems for providing depth-resolved real-time visual feedback to a physician during cosmetic dermal filler injections with micrometer spatial resolution utilizing a noninvasive optical coherence tomography/elastography, 2D-3D virtual and real time system. This system can be automated to direct proper volumes and viscosity of the necessary injection substances. The methods and systems allow for assessment of the elasticity of the tissue before and after the injection to evaluate the efficacy of the injection, with predetermined virtual results before and matched post injection images. The elasticity assessment method preferably utilizes a focused air-pulse to induce a micrometer scale displacement in the skin and the optical coherence tomography system to image this displacement. By utilizing a model-based reconstruction method, the viscoelasticity of the tissue at a specific measurement position can be obtained and virtual and post injection real time projections can be imaged.
