20090255893Interconnecting Bottles Utilized to Create Structures - The present invention consists of a water or soda bottle or vessel which is designed to allow for the bottle to interconnect with other bottles of similar design and standard dimensions to form useful second use products. A recess in the lower surface of the bottle receives the neck of another storage bottle. There are recesses perpendicular to the vertical axis of the bottle capable of receiving the mating side recess of another storage bottle. There are two such recesses on each storage bottle, one on each side of the bottle, parallel to each other. This allows for a bottle positioned on its side perpendicular to a vertically positioned bottle to be used to connect two vertically perpendicular storage bottles10-15-2009

20110242313Contamination 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
20110279278Monitoring 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
20120106357VARIABLE 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
20120135691NOISE-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

20130128786WIRELESS 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

20120014418Multi-configuration adaptive layered steered space-time coded system and method - The multi-configuration adaptive layered steered space-time coded (LSSTC) wireless transmission system utilizes Layered Steered Space-Time Codes (LSSTC), a recently proposed multiple-input multiple-output (MIMO) system that combines the benefits of the vertical Bell Labs space-time (V-BLAST) scheme, space-time block codes (STBC) and beamforming. A multi-configuration transmission scheme based on LSSTC and V-BLAST systems uses threshold-based decision making to change the modulation type and the MIMO transmission scheme in order to optimize error performance.01-19-2012
20120014462Optimal power allocation method for an LSSTC wireless transmission system - The optimal power allocation method for an LSSTC wireless transmission system utilizes Layered Steered Space-Time Codes (LSSTC), a recently proposed multiple-input multiple-output (MIMO) system that combines the benefits of vertical Bell Labs space-time (V-BLAST) scheme, space-time block codes (STBC), and beamforming. A new downlink scheme employs LSSTC with optimal power allocation based on the assumption that the user feeds the base station (BS) with the average signal-to-noise ratio (SNR) per V-BLAST layer through the uplink feedback channel. Such a system enhances the error performance by assigning power to the layers in an optimum manner.01-19-2012
20150071161AMPLIFY AND FORWARD RELAY METHOD - The amplify and forward relay method enhances QOS in wireless networks and is based on the switch-and-examine (SEC) and SEC post-selection (SECps) diversity combining techniques where only a single relay out of multiple relays is used to forward the source signal to the destination. The selection process is performed based on a predetermined switching threshold. Maximal-ratio combining (MRC) is used at the destination to combine the signal on the relay path with that on the direct link.03-12-2015
