20140266967 | Metamaterial Particles for Electromagnetic Energy Harvesting - Antennas developed for electromagnetic field energy harvesting, typically referred to as rectennas, provide an alternative electromagnetic field energy harvesting means to photovoltaic cells if designed for operation in the visible frequency spectrum. Rectennas also provide energy harvesting ability or power transfer mechanism at microwave, millimeter and terahertz frequencies. However, the power harvesting efficiency of available rectennas is low because rectennas employ traditional antennas whose dimensions is typically proportional or close to the wavelength of operation. This invention provides a device for electromagnetic field energy harvesting that employs a plurality of electrically-small resonators such as split-ring resonators that provide significantly enhanced energy harvesting or energy collection efficiency while occupying smaller footprint. The invention is applicable to electromagnetic energy harvesting and to wireless power transfer. | 09-18-2014 |

20160124031 | SMART MULTI-PURPOSE MONITORING SYSTEM USING WAVELET DESIGN AND MACHINE LEARNING FOR SMART GRID APPLICATIONS - A new voltage-based index is formulated in the time-frequency domain (using wavelets) and the energy of the wavelet coefficients associated with the change in mean voltage is used to extract the islanding features rather than using the energy of the wavelet coefficients themselves as in the prior art. Procrustes analysis is used to design the new wavelet, namely WGM1.0, by only satisfying the minimum properties on the wavelet filter of length 6 (i.e., six coefficients). Machine learning is then used to develop islanding classification models based on the calculated voltage index and the new wavelet. Two classifiers are used for the present invention: Support Vector Machine (SVM) and Ensemble Tree classifier (ETC). | 05-05-2016 |
