| 20110267038 | SHUNT SENSOR AND SHUNT SENSOR ASSEMBLY - The present disclosure describes configurations for current shunt sensors and current shunt sensor assemblies having improved electromagnetic cross-talk rejection that can be used in single-phase/split-phase and poly-phase power metering applications. Some embodiments of the current shunt sensors and current shunt sensor assemblies reduce the need for a shielding material around current shunt sensors in single-phase/split-phase and poly-phase power metering applications. Some embodiments of the current shunt sensors achieve improved electromagnetic cross-talk rejection through a substantially symmetrical arrangement of component parts along the primary path of current flow. Some embodiments of the current shunt sensors achieve improved electromagnetic cross-talk rejection by symmetrical configurations that, in operation, induce complementary parasitic currents or voltages that substantially cancel each other out and do not substantially affect primary current flow through the current shunt sensor. | 11-03-2011 |

| 20100023464 | Systems and methods for parameter adaptation - A method of parameter adaptation is used to modify the parameters of a model to improve model performance. The model separately estimates the contribution of each model parameter to the prediction error. It achieves this by transforming to the time-scale plane the vectors of output sensitivities with respect to model parameters and then identifying the regions within the time-scale plane at which the dynamic effect of individual model parameters is dominant on the output. The method then attributes the prediction error in these regions to the deviation of a single parameter from its true value as the basis of estimating individual parametric errors. The proposed Signature Isolation Method (PARSIM) then uses these estimates to adapt individual model parameters independently of the others, implementing, in effect, concurrent adaptation of individual parameters by the Newton-Raphson method in the time-scale plane. The Signature Isolation Method has been found to have an adaptation precision comparable to that of the Gauss-Newton method for noise-free cases. However, it surpasses the Gauss-Newton method in precision when the output is contaminated with noise or when the measurements are generated by inadequate excitation. | 01-28-2010 |

| 20090150918 | SYSTEM AND METHOD FOR INDEPENDENT MEDIA AUDITING AND MEDIA SERVING FOR MARKETING CAMPAIGNS PRESENTED VIA MEDIA DEVICES IN PUBLIC PLACES - An independent auditing and ad service system that may be utilized in conjunction with a system for presenting marketing campaigns to audiences via a network of players located in public locations. Independent agents in the players monitor media content that is presented to audiences during marketing campaigns and generate independent agent playlogs that are provided to a content registry service. The content registry service compares the independent agent playlogs with playlogs that are provided by a network operator to validate the network-operator-generated playlogs. The independent agent playlogs may also be provided to an analytics service where they are used to analyze the performance of marketing campaigns. Based on the analyzed performance, the service may determine that the media content being presented to audiences via the media players should be changed. The independent agents may be instructed to implement recommended changes by modifying the media content being presented on the players. | 06-11-2009 |

| 20090051496 | Method and Apparatus for Low Power Modulation and Massive Medium Access Control - An ultra low power, low complexity, low collision, deterministic modulation method that also works as a massive medium access mechanism for communication systems is based on positioning data in a communication resource space, such as time and frequency, such that the position of a symbol in that space determines its value and its access to the medium. The number base of the symbol is determined by the size of the subset of the resource space it is positioning itself in and, thereby, a few sparsely located symbols can convey a large value, while the remainder of the space can be simultaneously and massively used by other sparsely resource using members of the network. | 02-26-2009 |
| 20090264067 | Inductive antenna coupling - This invention pertains to the connection between a radio frequency circuit and its antenna. Miniaturization of radio frequency integrated circuits has made attaching these circuits to their antennas increasingly difficult and costly. This invention uses magnetic coupling, as performed in transformers, between circuits and antennas as a practical solution to reduce cost and effort in attaching the two sides as well as to protect the circuit against electrostatic discharge. Furthermore a simple pre-assembly testing methodology is accounted for as an additional benefit of the method. | 10-22-2009 |
