Abstract: Various implementations disclosed herein include devices, systems, and methods that provide customized feedback content during a meditation experience. For example, an example process may include obtaining physiological data via one or more sensors, determining that an attentive state based on the physiological data, customizing feedback content based on a user attribute to change the attentive state during the meditation mode, and providing the customized feedback content during the meditation mode after a delay time based on the user attribute.

Abstract: The present invention includes a process for producing carbon filaments and synthesis gas from a mixture of alkanes, preferably natural gas, comprising converting a first portion of the alkanes, preferably C2+ hydrocarbons, directly to carbon filaments and converting a second portion of the alkanes, preferably methane, to syngas. The natural gas may be separated into a first feed stream comprising ethane, propane, and butane and a second feed stream comprising methane. The first feed stream is fed to a carbon filament CF reactor to produce carbon filaments and hydrogen. The second feed stream is fed to a syngas production reactor to produce syngas. Alternatively, the natural gas is fed to at least one carbon filament reactor that is maintained at an effective temperature to convert C2+ hydrocarbons in the natural gas to carbon filaments and hydrogen, thereby filtering methane from the natural gas.

Abstract: An improved test for quantifying luster of petroleum products in particle form, especially coke, as an index of quality. A representative sample of the product is obtained and prepared. A digital image of the sample is formed using a scanner. The image is then processed digitally to produce a representative luster or optical density measurement for the sample. The preceding process may be repeated several times for each sample and the resultant luster or optical density measurements for each iteration are totaled and averaged. Once the luster measurement or optical density for the sample is obtained, it is compared to established parameters to assign a CTE value to the sample, assuming there is sufficient historical data correlating the two measurements. Various refining operating parameters including feedstocks, temperatures and pressures, may be altered to obtain a desired product.

Abstract: A submicron-particle-enhanced catalyst and method for its making are disclosed. The catalyst comprises <1 micron diameter particles distributed over the surface of a monolith or divided carrier to provide a high surface area catalyst having highly dispersed catalytic active sites available for catalyzing fast chemical reactions at short contact time and high space time yield. A syngas production method carried out in a short contact time reactor is disclosed in which a gaseous stream of light hydrocarbon and O2 is passed over a submicron-particle-enhanced catalyst to produce a mixture of carbon monoxide and hydrogen.

Abstract: An apparatus and method for printing or coating material and supporting the material during printing or coating thereon by either offset-gravure or direct roll equipment includes a cylindrical support member having flexible bristles radiating therefrom. The bristles are of a suitable diameter, length and spacing to form a generally cylindrical brush that is oriented in spaced relation to a contact printing or coating roller and adapted to yield or bend when coming in contact with contoured or uneven portions of the material and thereby fully support the lower surface of the material as the upper surface of the material is being printed upon or coated.

Abstract: Apparatus for measuring the formation of crystals in a flowing liquid using a flow way that receives a flow of the liquid therethrough; wherein, the flow way includes an optical means and access for illuminating the liquid with a beam of polarized light and then imaging the illuminated liquid to qualitatively ascertain the rate and type of crystal formation within the liquid.
