| 20110071700 | Auto-Compensating Power Converter - An auto-compensation method for compensating power regulators configured to generate a regulated output voltage. Auto-compensation may be performed dynamically by determining various coefficients of a compensation function used in compensating the power regulator, based on assumptions about the structure of the regulator and corresponding filters. The method may be used to determine at least the DC loop gain and the position of the compensation zeros, without requiring any prior knowledge of the values of the various components of the system. Furthermore, the selection of the compensation parameters (loop gain, position of zeroes) may be based on measurement of various state variables of the actual power converter, and adjustment of the various coefficients of the compensation function according to the measurements. Since no power-plant model of the power regulator is used, inaccuracies that would be inherent using any method that employs a model of the system instead of the system itself may be eliminated. | 03-24-2011 |

| 20100101027 | Innerspring Mattress System - There is disclosed a mattress comprising a first border member configured to define an upper periphery of the mattress and a second border member configured to define a lower periphery of the mattress. At least two spring assemblies are positioned within the first and second border members so as to extend between the first and second border members. Each spring assembly comprises an array of coil springs and each spring assembly is positioned such that the coil springs of one spring assembly are not directly connected with coil springs of any other spring assembly. | 04-29-2010 |

| 20080233336 | Carpet Tiles and Methods Of Making Same - Modular carpet tiles having multiple layers are described, including a laminate layer having a compatibilizing agent. The laminate layer can include at least one polyolefin functionalized with at least one unsaturated organic acid and/or at least one unsaturated organic acid anhydride, such as maleic anhydride. The functionalized polyolefin can have an acid number from about 5 to about 55 mg KOH/g. Methods of making the tiles are also described. | 09-25-2008 |
