| 20090307148 | Method And System For Generating An Index Of Securities - A method for generating an index of securities includes selecting index constituents and weighing the selected index constituents by a measure (“an intangible asset measure”) of quality and/or value of the intangible assets of constituent entities. The index constituents can be selected from a set of potential constituents based on an intangible asset measure of each constituent in the set, and the selected index constituents may then be weighted by a desired measure or methodology or weighted equally, or by an intangible asset measure. Another method for generating an index of securities includes combining groups of constituents, which are selected based on an intangible asset measure, to be index constituents and weighing the index constituents by a desired measure or methodology. The groups of constituents may be stocks of existing indices having assigned weights in the existing indices based on intangible asset measures of the stocks. These assigned weights of the stocks may be used in a calculation of the weights of the index constituents which correspond to these stocks. | 12-10-2009 |

| 20080271803 | Cable jacket sealing, pressurization, and monitoring - An underwater power generating system includes an underwater power generating device, a closed nacelle and a connecting cable system that is provided with an open passage way extending there along that is sealed at one end to the interior of the closed nacelle. The cable system can be used in a number of ways, such as by having the second end being sealed, to prevent air from escaping the closed nacelle, or by having the second end connected to a source of positive pressure thereby permitting the cable to be sufficiently pressurized to provide a positive pressure internally within the closed nacelle that is at least slightly greater than the nacelle at depth pressure, and thus greater than water pressure acting on the exterior of the closed nacelle, to prevent water ingress within the nacelle, as well as to transmit power and/or other data between the nacelle and shore monitoring and control facilities. | 11-06-2008 |
| 20080290735 | Remanent voltage generator tachometer and control for induction machine - In a power generating system the remanent voltage of an induction machine is measured. The frequency of the remanent voltage is compared to a predetermined threshold. When the frequency of the remanent voltage is greater than the predetermined threshold the induction machine is connected to the power grid. Induction machine is disconnected from power grid once generated power drops below a predetermined threshold. Once the induction machine is disconnected, it is prevented from being reconnected to the power grid until a predetermined time period elapses. | 11-27-2008 |

| 20100264312 | SUPERCONDUCTING SOURCE FOR TUNABLE COHERENT TERAHERTZ RADIATION - A system includes a solid state source of THz radiation and a detector. The source of THz radiation may be based on a superconducting material, such as materials containing one or more Josephson junctions (e.g. BSCCO). The source may include a crystal of superconducting material on which a mesa of superconducting material is formed. The resonant coupling between the Josephson oscillations and the fundamental cavity mode of the mesa may lead to synchronization of the Josephson junctions and emission of powerful THz radiation. The mesa may be formed and/or handled such that THz radiation can be emitted by the material without requiring application of an external magnetic field (e.g. the mesa may include a non-uniform compositional gradient, a non-uniform shape, may have radiation non-uniformly applied to the mesa, etc.). | 10-21-2010 |

| 20110004864 | Method of Dynamically Linking Objects Operated on by a Computational System - In a method for presenting to a user information operated on by a computational software application, a relationship between states of a user interface mechanism located on a workspace associated with the computational software application and an underlying object operated on by the computational software application may be determined. The relationship may be defined at least in part by configuration data capable of being interpreted by the computational software application. A change in a value of the underlying object may be detected, and a current state of the user interface mechanism may be changed based on the detected change in the value of the underlying object and according to the relationship. Additionally, a change in the current state of the user interface mechanism caused by a user may be detected, and the current value of the underlying object may be changed based on the detected change in the current state of the user interface mechanism and according to the relationship. | 01-06-2011 |

| 20080250347 | Method and System for Presenting Input Expressions and Evaluations of the Input Expressions on a Workspace of a Computational System - In a method for presenting information, an interactive document, for example, may be created that includes both an input expression and a result generated by evaluating the input expression, and where the input expression can be selectively hidden. This may permit “decluttering” of the document so that it may be easier to follow. At the same time, user interface mechanisms allow a viewer to reveal the input expression if the view desires to see the input expression. In this method, an input expression and a result corresponding to an evaluation of the input expression are presented on a workspace associated with a computational software application. Additionally, a first user interface mechanism associated with the input expression is presented on the workspace. In response to an activation of the first user inter mechanism, the input expression may be hidden on the workspace, while the result is presented on the workspace. Also, a second user interface mechanism associated with the input expression may be presented on the workspace. In response to an activation of the second user interface mechanism, the input expression is presented on the workspace. | 10-09-2008 |
