| 20090048876 | SYSTEM AND PROCESS FOR A FUSION CLASSIFICATION FOR INSURANCE UNDERWRITING SUITABLE FOR USE BY AN AUTOMATED SYSTEM - A method and system for fusing a collection of classifiers used for an automated insurance underwriting system and/or its quality assurance is described. Specifically, the outputs of a collection of classifiers are fused. The fusion of the data will typically result in some amount of consensus and some amount of conflict among the classifiers. The consensus will be measured and used to estimate a degree of confidence in the fused decisions. Based on the decision and degree of confidence of the fusion and the decision and degree of confidence of the production decision engine, a comparison module may then be used to identify cases for audit, cases for augmenting the training/test sets for re-tuning production decision engine, cases for review, or may simply trigger a record of its occurrence for tracking purposes. The fusion can compensate for the potential correlation among the classifiers. The reliability of each classifier can be represented by a static or dynamic discounting factor, which will reflect the expected accuracy of the classifier. A static discounting factor is used to represent a prior expectation about the classifier's reliability, e.g., it might be based on the average past accuracy of the model, while a dynamic discounting is used to represent a conditional assessment of the classifier's reliability, e.g., whenever a classifier bases its output on an insufficient number of points it is not reliable. | 02-19-2009 |

| 20100164688 | AUXILIARY DEVICE FOR IMPLANTABLE UNITS - In at least some embodiments, an auxiliary device compatible with a biomedical implantable comprises a first transceiver and a controller coupled to the first transceiver. If the first transceiver receives a wireless data signal from an implantable unit, the controller generates a corresponding data signal for transmission to a wireless network. The corresponding data signal has at least one of a higher power level and a higher frequency band compared to the wireless data signal. | 07-01-2010 |
| 20100202494 | ULTRA WIDEBAND MODULATION FOR BODY AREA NETWORKS - A symbol modulation system applicable to a body area network is disclosed herein. The symbol modulation system includes a symbol mapper. The symbol mapper is configured to determine a time within a predetermined symbol transmission interval at which a transmission representative of the symbol will occur. The time is determined based on a value of a symbol and a value of a time-hopping sequence. The time is selected from a plurality of symbol value based time slots, and a plurality of time-hopping sequence sub-time-slots within each symbol value based time slot. The symbol mapper is configured to generate a single guard interval within the symbol transmission interval. The single guard interval is positioned to terminate the symbol transmission interval. | 08-12-2010 |

| 20090177456 | Mixed Decoupled Electromagnetic Circuit Solver - In a method, system and computer readable medium for determining a composite circuit model of a 3D geometry, first and second sides of an analytical model of the 3D geometry are discretize into first and second surface and/or volume meshes. For each mesh, a current that flows in each cell thereof and the a voltage induced in the cell in response to the application of an exemplary bias to the geometry are determined. For each mesh, from the currents flowing in the cells thereof and voltages induced in the cells thereof, a corresponding circuit model is determined. The circuit models of the meshes are then combined to form a composite circuit model for the geometry. | 07-09-2009 |
