Mitigation of Adverse Effects of Geomagnetically Induced Currents on TransformersGeomagnetically induced currents (GIC) are quasi-dc currents and consequently cause saturation of transformers which may be overheated and, in the worst case, be permanently damaged. Therefore, the mitigation of GIC effects on power transformers is very important. Conventional approaches to mitigate the GIC are expensive and have no sophisticated control mechanism. This invention proposes to design a novel and cost-efective methof of mitigating the adverse effects of geomanetic induced current (GIC) on power transformers by using fuzzy logic controlled variable resistor to be connected at the neutral of the transformers. Another advantage of the proposed method is that it can minimize the zero sequence current flowing through the neural of transformers during any unbalanced faults in the power network.10530144

Fully Reconfigurable Modular Body-Worn Sensors This invention is a sensor level modular and fully reconfigurable EEG system along with other body-worn sensors that will allow Lego-like connectivity of multi-modal sensors on the body. this is achieved by elimination of the DRL circuit from the traditional EEG (and ECG) circuit design with a new analog front end design that is independent for each channel. Consequentially, a system is envisioned where the number of EEG channel (sensor nodes) can be one or many, independent of the design, and can be customized at the time of deployment in a Lego-Like fashion. Subsequently, such system can incorporate any type of body worn sensors with the network. Additionally, the sensors can be equipped to perform some computation on the local sensor data that will enable distributed intelligence. The outcomes will enhance capabilities of neurological and physiological data collection at natural environments10973430
