Abstract: Various aspects and embodiments are directed to a streamlined computer device and a graphical user interface that organizes interface elements into views of computer content for presentation to a user. Various views of digital media content permits users to easily and efficiently access various digital media content. Different views are used to provide an interface that is responsive to configurations of the device and responsive to activity being performed by the user. Aspects include permitting the user to maintain and manage digital media content libraries. According to some embodiments, the libraries comprise user digital media content and references digital media content. Functionality provided to a user can be tailored to the type of content displayed, accessed and/or managed. According to various aspects, methods and systems are provided for accessing and managing digital media libraries on a streamlined computing device with a plurality selectable I/O profiles.

Abstract: In various implementations, a method for stimulating a downhole rock formation may include propagating pressure waves into the downhole rock formation and deforming the downhole rock formation via the pressure waves. An apparatus for stimulating a downhole rock formation to enhance hydrocarbon recovery may include an acoustic assembly that emits pressure waves, the acoustic assembly having a first end and a second end; a mass coupled with the first end; and a transmission component coupled with the second end. The transmission component may be configured to transmit the emitted pressure waves into the downhole rock formation to deform the downhole rock formation. A system for stimulating a downhole rock formation to enhance hydrocarbon recovery may include at least one acoustic assembly configured to emit pressure waves and transmit the emitted pressure waves into the downhole rock formation to deform the downhole rock formation.

Abstract: in various implementations, a field-deployable system may include an array of two or more acoustic transducers arranged to propagate pressure waves through a hydrocarbon fluid medium. A method of stimulating a hydrocarbon fluid medium may include propagating pressure waves through the hydrocarbon fluid medium. The pressure waves may have an ultrasonic frequency and an amplitude sufficient to induce acoustic cavitation in the hydrocarbon fluid medium. A method of stimulating a solvent fluid medium may include propagating pressure waves through the solvent fluid medium, and inducing acoustic cavitation in the medium via the pressure waves. The acoustic cavitation may form a microjet that impinges a proximate solid surface to substantially remove hydrocarbon residue. An acoustic transducer may be configured to propagate pressure waves through a hydrocarbon fluid medium. The pressure waves may have an ultrasonic frequency and an amplitude sufficient to induce acoustic cavitation in the hydrocarbon fluid medium.

Abstract: A system and a method for creating a stable and reproducible interface of an optical sensor system for measuring blood glucose levels in biological tissue include a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic includes a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal is maximized by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. Optimally, a medium may be injected between the disposable and the skin to match the respective refractive indices and optimize the signal collection of the sensor.
