20090069615 | METHOD AND EQUIPMENT FOR PREPARING ISOBUTYLENE USING TERTIARY BUTYL ALCOHOL - This invention discloses a method and equipment for preparing isobutylene using tertiary butyl alcohol. The equipment comprises a reaction vessel and a separating column. The upper portion of the separating column is fitted with a column top condenser, and the bottom of the column is fitted with a heater. The reaction vessel and the separating column are connected to each other by means of a pipe. One end of the dehydration column is connected to the heater at the bottom of the separating column, and the other end, after passing through a cooling unit, is connected to a distributor at the top of the separating column. A condenser with an outlet is connected to the outside of the said column top condenser. Isobutylene gas, which is generated as the solid superacid catalyst continuously reacts with and splits the tertiary butyl alcohol being introduced into the reaction vessel, flows together with boiling tertiary butyl alcohol gas into the separating column and is conducted by the distributor to the dehydrated extractant. Isobutylene gas flows out of the top of the column and passes through the condenser whereby it is cooled to become liquid isobutylene finished product. Unreacted tertiary butyl alcohol is condensed by the column top condenser to form liquid condensate, part of which is refluxed within the column and part of which flows out, returning to the reaction vessel. The dehydrated extractant passes through the distributor and enters the separating column from the top of the column. After the moisture in the rising gas is extracted and separated, it flows to the bottom of the column. After the dehydrated extractant has absorbed water, it is sent to the dehydration column where it is heated, the steam is separated from it, and the product is obtained. | 03-12-2009 |

The optical navigation module includes a substrate defining a base plane that is perpendicular to the operation plane; a light source installed on the base plane of the substrate and configured to emit light to a side of the substrate; an optical structure installed at the side of the substrate; a light sensor installed on the base plane of the substrate; a light shield installed on the base plane of the substrate spatially separating the light source and the light sensor so that light emitted by the light source is not directly shed on the light sensor, the light shield having an aperture formed thereon; and a tactile switch for executing a command installed at a side of the light source that is opposite to the side facing the operation plane. The optical structure is configured to guide the light emitted from the light source to the object so that at least a portion of the light scattered by the object passes to the light sensor through the aperture on the light shield and forms a light intensity pattern on the light sensor. | 01-10-2013 |

20150376112 | Photoactivatable Caged Compounds with AIE Characteristics: Method of Preparation and Applications - A photoactivatable caged compound (TPE-C) with AIE characteristics is designed and synthesized. TPE-C is non-emissive either in solution or in aggregated state, but its luminescence can be induced to emit strong cyan emission in aggregated state by UV irradiation. Such property enables TPE-C to be applied in photo-patterning and anti-counterfeiting related areas. | 12-31-2015 |

20130089889 | Aggregation Induced Emission Active Cytophilic Fluorescent Bioprobes for Long-Term Cell Tracking - Fluorescent bioprobes comprising fluorogen formed nanoparticles comprising fluorogens with aggregation-induced emission (ATE) properties, which can be used for long-term cell tracking. The fluorogens are nonemissive in organic solution but become highly emissive when aggregated in aqueous solution. The fluorescent molecules can readily pass through cell membranes, stain only the cell cytoplasm, and form highly emissive nanoaggregates in aqueous media without any obvious cytoxicity in the living cells. Furthermore, the molecules can be retained inside the cells without noticeable leakage to the outside. Therefore, these ATE-based compounds can be used as selective and cell-compatible fluroescent bioprobes for long-term live cell tracking and imaging. | 04-11-2013 |

20140212373 | Multi-Vinylsulfone Containing Molecule - A multi-vinylsulfone containing molecule is described herein. The multi-vinylsulfone containing molecule can be formed by dissolving a water soluble polymer containing a hydroxyl group in an aqueous solution to form a polymer solution; adding a molecule containing two vinylsulfone groups to the polymer solution; and forming a modified polymer by controlling a number of the vinylsulfone groups that are added to the polymer. A hydrogel is also described herein that can include the multi-vinylsulfone containing molecule and a multi-thiol containing molecule. The hydrogel can be formed from an aqueous solution that includes the multi-vinylsulfone containing molecule and the multi-thiol containing molecule by undergoing gelatation upon delivery to a site in the body. Also described is a drug delivery system that employs the hydrogel. | 07-31-2014 |
20150087725 | Injectable Gelling Material - A material is described herein. The material includes a multi-vinylsulfone containing molecule and a multi-nucleophile containing molecule. The material can form a hydrogel from an aqueous solution with dissolved multi-vinylsulfone and a multi-nucleophile. The aqueous solution can undergo gelation with a controllable gelation time to form the hydrogel upon administration to a space in a body. The hydrogel can form in situ with controllable properties, which allow the hydrogel to be used in many biomedical applications. Examples of biomedical applications include, but are not limited to, a volume/filler expander, a storage and delivery mechanism for biologics, and as a tissue interacting surface. | 03-26-2015 |
20160038599 | Biocompatible in situ Hydrogel - The present invention provides compositions, and related kits and methods, for formation of hydrogels.

20100016072 | Group users authentication and authorization using time reversal transformation - Alphabets consisting of letters (‘A’-‘Z’) minus ‘O’ and digits (‘0’-‘9’) are used to form a sequential code where all the codewords are unique. A sequential codeword is used to generate another unique pseudo-random codeword with larger code length using the Time Reversal Transformation (TRT). A TRT codeword is divided into a number of equal-sized sub-codewords which are used to authenticate a group of users to play Internet-based hand-held video games. A sub-codeword has the format that every two alphabets are followed by a digit to avoid the possibility of the occurrence of any obscene words. | 01-21-2010 |
