| 20090210939 | SKETCH-BASED PASSWORD AUTHENTICATION - A graphical password authentication method is based on sketches drawn by user. The method extracts a template edge orientation pattern from an initial sketch of the user and an input edge orientation pattern from an input sketch of the user, compares the similarity between the two edge orientation patterns, and makes an authentication decision based on the similarity. The edge orientations are quantized, and each edge orientation pattern includes a set of quantized orientation patterns each corresponding to one of the quantized edge orientations. The number of quantized edge orientations, as well as other parameters such as the dimension of the final orientation patterns and acceptance threshold, can be optimized either globally or user-specifically. | 08-20-2009 |
| 20090219286 | NON-LINEAR BEAM TRACING FOR COMPUTER GRAPHICS - A non-linear beam tracing technique that supports full non-linear beam tracing effects including multiple reflections and refractions for computer graphics applications. The technique introduces non-linear beam tracing to render non-linear ray tracing effects such as curved mirror reflection, refraction, caustics, and shadows. Beams are allowed to be non-linear where rays within the same beam are not parallel or do not intersect at a single point. Such is the case when a primary beam bounces off of a surface and spawns one or more secondary rays or beams. Secondary beams can be rendered in a similar manner to primary rays or beams via polygon streaming. Beyond smooth ray bundles, the technique can also be applied to incoherent ray bundles which is useful for rendering bump mapped surfaces. | 09-03-2009 |

| 20110289015 | MOBILE DEVICE RECOMMENDATIONS - Users may browse web pages, interact with a plethora of applications, search for new content, and perform a wide variety of other tasks using a mobile device. Unfortunately, useful content may be difficult for a user to locate because of the large amount of content available (e.g. hundreds of thousands of applications within an application store). Accordingly, one or more systems and/or techniques for determining recommendations are disclosed herein. In particular, user input (e.g., text, numbers, etc.) and/or a user profile (e.g., contextual information relating to a user) may be used to determine a user intent. Recommendations may be determined based upon the user intent. For example, a user may input “I am hungry” using a mobile phone having a GPS location of Downtown and a noon timestamp. Using this information, an application allowing the user to make lunch reservations at local restaurants may be provided as a recommendation. | 11-24-2011 |

| 20100213102 | CATALYTIC CONVERSION PROCESS - A catalytic conversion process which comprises catalytic cracking reaction of a hydrocarbon feedstock contacting with a medium pore size zeolite enriched catalyst in a reactor, characterized in that reaction temperature, weight hourly space velocity and catalyst/feedstock ratio by weight are sufficient to achieve a yield of fluid catalytic cracking gas oil between 12% and 60% by weight of said feedstock, wherein said weight hourly space velocity is between 25 h | 08-26-2010 |
| 20100248942 | CATALYST REGENERATION PROCESS FOR IMPROVING CATALYST SELECTIVITY - The object of the present invention is to provide a catalyst regeneration process which can improve catalyst selectivity. A first aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a first fluidized bed regenerator and contacted with an oxygen-containing gas stream and optional steam to carry out a coke combustion reaction, wherein the resultant mixture of the partially regenerated catalyst and flue gas is introduced into a second fluidized bed regenerator and contacted with steam and an optional oxygen-containing gas stream to carry out a further regeneration reaction, and then the regenerated catalyst is introduced into the reactor. A second aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a fluidized dense bed regenerator and contacted with an oxygen-containing gas stream and steam to carry out a coke combustion reaction, and then the regenerated catalyst is introduced into the reactor. The inventive processes result in a more uniform distribution of the regenerated catalyst activity; due to the exposure of the catalyst to a low temperature for a long time, a part of the heavy metals are buried by the matrix and the remaining are passivated. Thereby dry gas and coke yields decrease sharply when hydrocarbons are subjected to a catalytic cracking reaction on the regenerated catalyst. | 09-30-2010 |
| 20100326888 | CATALYTIC CRACKING CATALYST HAVING A HIGHER SELECTIVITY, PROCESSING METHOD AND USE THEREOF - The present invention provides a catalytic cracking catalyst, processing method and use thereof. When the catalyst is added into a commercial catalytic cracking unit, it has an initial activity of not higher than 80, preferably not higher than 75, more preferably not higher than 70, a self-balancing time of 0.1-50 h, and an equilibrium activity of 35-60. Said method enables the activity and selectivity of the catalyst in the catalytic cracking unit to be more homogeneous and notably improves the selectivity of the catalytic cracking catalyst, so as to obviously reduce the dry gas and coke yields, to sufficiently use steam and to reduce the energy consumption of the FCC unit. | 12-30-2010 |
| 20110000818 | PROCESS FOR CONVERTING INFERIOR FEEDSTOCK TO HIGH QUALITY FUEL OIL - A catalytic conversion process can convert inferior feedstock to high quality fuel oil and propylene. A inferior feedstock is introduced into first and second reactor zone, wherein the feedstock carry out first step and second step reactions by contacting with catalytic conversion catalyst. Product vapors separate from spent catalyst by gas-solid separation. The spent catalyst is stripped, regenerated by burning off coke and then returns to reactor. The product vapors are introduced into separation system to obtain propylene, gasoline, diesel, fluid catalytic cracking gas oil (FGO) and other products. The FGO is introduced into hydrotreating unit and/or extraction unit to obtain hydrotreated FGO and/or extracted FGO. Said hyrotreated FGO and/or extracted FGO return to the first reactor zone and/or another catalytic cracking unit to obtain propylene and gasoline. The extracted oil of said FGO is rich in double ring aromatics which are good chemical materials. The raffinate of said FGO is rich in chain alkane and cycloalkane which are suitable for catalytic cracking. More particularly, the invention relates to a process to utilize petroleum oil resources efficiently for decreasing the yield of dry gas and coke significantly. | 01-06-2011 |
| 20110073523 | CATALYTIC CONVERSION PROCESS FOR PRODUCING MORE DIESEL AND PROPYLENE - The present invention relates to a catalytic conversion process for producing more diesel and propylene, comprising contacting the feedstock oil with a catalyst having a relatively homogeneous activity in a reactor, wherein the reaction temperature, weight hourly space velocity and weight ratio of the catalyst/feedstock oil are sufficient to obtain a reaction product containing from 12 to 60% by weight of a fluid catalytic cracking gas oil relative to the weight of the feedstock oil; the fluid catalytic cracking gas oil is fed into the fluid catalytic cracking gas oil treatment device for further processing. Catalytic cracking, hydrogenation, solvent extraction, hydrocracking and process for producing more diesel are organically combined together, and hydrocarbons such as alkanes, alkyl side chains in the feedstocks for catalysis are selectively cracked and isomerized. Meanwhile, aromatics in the feedstocks, which enter into the diesel fraction, are minimized, and the retention of other components in the diesel fraction by the production of aromatics via the reaction such as aromatization and the like is avoided. While the feedstocks are converted into high cetane number diesel and propylene, the yields of dry gas and coke are significantly reduced, and the breaking tendency and consumption of the catalyst are decreased. | 03-31-2011 |
