| 20110242313 | Contamination monitoring of high voltage insulators - Contamination monitoring of high voltage insulators provides a system and method producing an early predictor for high voltage insulator failure, allowing repairmen to either already be on site when a high voltage insulator fails in order to expedite repair time, or allowing repair and/or replacement of a faulty insulator before the failure actually occurs. The system and method provide transmission of an alarm signal when contaminant levels (such as equivalent salt deposit density (ESDD) levels) formed on a high voltage insulator exceed pre-selected threshold values, indicating the likelihood of high voltage insulator failure. | 10-06-2011 |
| 20110279278 | Monitoring and early warning alarm system for high voltage insulator failure - The monitoring and early warning alarm system for high voltage insulator failure provides an early predictor for high voltage insulator failure, allowing repairmen to either already be on site when a high voltage insulator fails in order to expedite repair time, or allowing repair and/or replacement of a faulty insulator before the failure actually occurs. The monitoring and early warning alarm system includes a housing adapted for mounting on a high-voltage power line in proximity to a high voltage insulator associated therewith. A temperature sensor, a contamination sensor, a humidity sensor, or combinations thereof are mounted on the housing and the measured ambient temperature, pollutant contamination and humidity are compared with pre-selected threshold values of temperature, humidity and pollutant contamination. A transceiver transmits an alarm signal when the measured ambient temperature, the measured humidity and/or the measured ambient pollutant contamination are greater than the respective pre-selected threshold values. | 11-17-2011 |
| 20120106357 | VARIABLE STEP-SIZE LEAST MEAN SQUARE METHOD FOR ESTIMATION IN ADAPTIVE NETWORKS - The variable step-size least mean square method for estimation in adaptive networks uses a variable step-size to provide estimation for each node in the adaptive network, where the step-size at each node is determined by the error calculated for each node, as opposed to conventional least mean square algorithms used in adaptive filters and the like, where the choice of step-size reflects a tradeoff between misadjustment and the speed of adaptation. | 05-03-2012 |
| 20120135691 | NOISE-CONSTRAINED DIFFUSION LEAST MEAN SQUARE METHOD FOR ESTIMATION IN ADAPTIVE NETWORKS - The noise-constrained diffusion least mean square method for estimation in adaptive networks is based on the Least Mean Squares (LMS) algorithm. The method uses a variable step size in which the step-size variation rule results directly from the noise constraint. | 05-31-2012 |

| 20130128786 | WIRELESS SENSOR NETWORK WITH ENERGY EFFICIENT PROTOCOLS - The wireless sensor network with energy efficient protocols includes a network of external sensors in communication with a data sink. The network utilizes an algorithm integrating a modified S-MAC (an algorithm for medium access control) protocol for decreasing energy usage in operating the node and associated sensors. A routing protocol is further integrated into the algorithm, the routing protocol being based upon cluster head rotation. | 05-23-2013 |
