| 20110321154 | SYSTEMS AND METHODS FOR GENERATING CONSTRAINTS FOR USE IN ACCESS CONTROL - In one embodiment the present invention includes a computer-implemented method for generating constraints for use in an access control system. In one embodiment, roles, document types, and permissions are stored in a 3-D model, such as a matrix or table. The 3-D model is converted to 2-D models, where users are inserted for roles and documents are inserted for document types. The 3-D model and 2-D models represent access rights. Supplemental information about the access rights is added to the 2-D tables. In one embodiment, attribute exploration is used to generate supplemental information. Constraints are generated from the 2-D tables for use in controlling access rights in a computer system. | 12-29-2011 |

| 20100190911 | METHOD FOR PRODUCING A DISPERSION COMPRISING A TWO STAGE REACTION PRODUCT AND AN ASSOCIATED COATING - The present invention is directed to a method for producing a dispersion comprising: (a) forming a first reaction product by reacting: (a1) at least one monomer comprising an ethylenically unsaturated double bond; (a2) at least one carboxylic acid group-containing monomer; and (a3) at least one glycidyl ester compound; wherein the molar ratio of (a2) to (a3) is substantially 1:1; (b) forming a second reaction product in the presence of the first reaction product by reacting: (b1) at least one monomer comprising an ethylenically unsaturated double bond; and (b2) at least one carboxylic acid group-containing monomer; and (c) reacting an amine compound with the second reaction product; and wherein steps (a), (b), and (c) are conducted in a substantially solvent free environment. | 07-29-2010 |
| 20100190923 | METHOD FOR PRODUCING A DISPERSION COMPRISING A ONE STAGE REACTION PRODUCT AND AN ASSOCIATED COATING - The present invention is directed to a method for producing a dispersion comprising: (a) reacting (i) a monomer comprising an ethylenically unsaturated double bond; (ii) a carboxylic acid group-containing monomer; and (iii) a glycidyl ester compound to form a reaction product comprising a carboxylic acid group; and (b) reacting the reaction product of (a) with an amine compound; and wherein there is a molar excess of (ii) to (iii); wherein steps (a) and (b) are conducted in a substantially solvent free environment and wherein the reaction product of (b) is not further reacted with a polyester polyol. | 07-29-2010 |

| 20110063838 | Solid State Bidirectional Light Sheet Having Vertical Orientation - A solid state, bidirectional light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. An array of LEDs (e.g., | 03-17-2011 |
| 20110163681 | Solid State Lamp Using Modular Light Emitting Elements - A solid state lamp, such as one that can replace an incandescent light bulb, has a base portion having an electrical connector for connection to a source of power, such as an Edison-type connector for connection to the mains voltage. An AC/DC converter in the base converts the mains voltage to a suitable light emitting diode (LED) drive voltage. A plurality of receptacles on the base connects to electrodes of plug-in modules. Each plug-in module supports a plurality of low power LEDs connected in series. The strings of LEDs on different modules are connected in parallel when connected to the receptacles. The modules and base are configured to allow a user to operate the lamp with different combinations of modules to generate a desired light output from the lamp. For example, the user can recreate the lumens equivalent of a 20 W, 40 W, or 60 W bulb by using one, two, or three modules. | 07-07-2011 |
| 20110163683 | Solid State Lamp Using Light Emitting Strips - In one embodiment, an LED lamp has a generally bulb shape. The LEDs are low power types and are encapsulated in thin, narrow, flexible strips. The LEDs are connected in series in the strips to drop a desired voltage. The strips are affixed to the outer surface of a bulb form to provide structure to the lamp. The strips are connected in parallel to a power supply, which may be housed in the lamp. Since many low power LEDs are used and are spread out over a large surface area, there is no need for a large metal heat sink. Further, the light emission is similar to that of an incandescent bulb. In other embodiment, there is no bulb form and the strips are bendable to have a variety of shapes. In another embodiment, a light sheet is bent to provide 360 degrees of light emission. Many other embodiments are described. | 07-07-2011 |
