Patent number: 11680134Abstract: A method for synthesizing polyolefin materials with a controlled degree of branching includes the following steps: polymerizing cyclic olefin monomers under catalyst conditions. The cyclic olefin monomer is shown in formula I, where n?0, n is an integer. By changing monomers and reaction parameters such as reaction temperature, solvent type, catalyst concentration, monomer concentration and reaction time, the degree of branching, the molecular weight and molecular weight distribution of polyolefin can be controlled. Compared with the existing process, the present invention is a new polymerization process, which can prepare the hyperbranched polyolefin with precise and controllable branching structure.

Patent number: 9964495Abstract: Near-field spray characteristics are established from local measurements which are acquired by data acquisition sub-system capable of complete scanning of the area (volume) of interest in the spray which uses different laser-based probes (shadowgraphy, PIV, diffraction) to obtain drops related measurements. A mechanical patternator measures volume flux distribution of the spray under study. The measurement data are post-processed to obtain spatially-resolved spray characteristics which are mapped in a spherical coordinate system consistent with the kinematics of the spray. A data compression scheme is used to generate compact analytical functions describing the nozzle spray based on the measurement data. These analytical functions may be useful for initiating the nozzle spray in computational fluid dynamics (CFD) based spray dispersion and fire suppression modeling.Type: GrantFiled: November 4, 2013Date of Patent: May 8, 2018Assignee: University of MarylandInventors: Andre W.

Patent number: 9355062Abstract: An initial (near-field) spray generated by a sprinkler under study is fully characterized using a laser-supported Shadowgraphy/PTV system. Near-field spray characteristics are established from local measurements, which are mapped in a spherical coordinate system consistent with the kinematics of the spray. A novel data compression scheme is introduced to generate analytical functions describing the sprinkler spray based on the measurements. These analytical functions are useful for initiating the sprinkler spray in computational fluid dynamics (CFD) based spray dispersion and fire suppression modeling. The near-field spray measurements and associated data compression approach are validated by comparing volume density measurements 1 meter below the sprinkler with volume density predictions generated from spray dispersion calculations initiated with the analytical spray functions.Type: GrantFiled: October 18, 2012Date of Patent: May 31, 2016Assignee: University of Maryland, College ParkInventors: Andre W.

Patent number: 8339667Abstract: Methods for processing print jobs in rendering devices include representing multiple to-be-printed objects with fewer such objects before processing of the objects occurs. In this manner, processing and memory requirements are optimized. Examples include utilizing a single raster operation function of one object for an entirety of objects; using fewer raster operation functions than originally required for the entirety of objects; creating a no processing (NOP) situation; and effectively creating a mask. Other aspects include modifying raster operation functions of one or more objects to have fewer variables than originally specified by the print job. Printers having stored or accessible computer executable instructions for performing the steps are also disclosed as are host devices that may direct or control the printer to perform the same.Type: GrantFiled: August 31, 2010Date of Patent: December 25, 2012Assignee: Lexmark International, Inc.Inventors: Raymond E.
