    Abstract: Embodiments described herein generally relate to devices and methods for stimulation or recording of accommodation of an eye. Accommodation of an eye naturally occurs through contraction of the ciliary muscle. Embodiments described herein can deliver electrostimulation to the ciliary muscle through a pair of electrodes which deliver power over an area of the sclera which is both positioned above and over an area which is substantially equivalent to the surface area of the ciliary muscle. In further embodiments, electrical impulses produced by the ciliary muscle can be received by one or more electrodes positioned proximate the ciliary muscle. Thus, by embodiments described herein, accommodation of the eye can be reproducibly achieved by external stimulation of the ciliary muscle or measured based on electrical impulses generated by or in conjunction with the ciliary muscle.

    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.
