20130227474 | CLICLKESS GRAPHICAL USER INTERFACE FOR DISPLAYING AND SELECTING A POP-UP MENU - The clickless graphical user interface provides a pop-up window when a cursor is moved over designated areas on the screen. The pop-up window includes menu item choices, e.g., “double click”, “single click”, “close” that execute when the cursor is moved over the item. This procedure eliminates the traditional ‘mouse click’, thereby allowing users to move the cursor over the application or file and open it by choosing among the aforementioned choices in the file or application being focused on. The pop-up window shows the navigation choices in the form of a text, e.g., yes/no or color, e.g., red/blue, or character, such as triangle for ‘yes’ and square for ‘no’. Pop-up window indicator types are virtually unlimited and can be changed to any text, color or character. The method is compatible with touch pads and mouse interface devices. | 08-29-2013 |
20140174946 | SYSTEM AND METHOD FOR ESTIMATING IMPEDANCE IN ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY - The method for estimating impedance in electrochemical impedance spectroscopy is an iterative method, combining high order statistic (HOS) deconvolution and adaptive filtering (AF) to estimate impedance in electrochemical impedance spectroscopy for such applications as measuring the degree of electrolytic corrosion in a coated metal pipe, for example. | 06-26-2014 |
20140190113 | ULTRA-HIGH PERFORMANCE CONCRETE REINFORCEMENT BARS - The ultra-high performance concrete reinforcement bars replace conventional steel tension bars and the like in the reinforcement of construction elements, such as concrete beams. The ultra-high performance concrete reinforcement bars are formed from ultra-high performance concrete reinforced with steel fiber. The reinforcement bars are preferably deformed to improve bonding at the interface between conventional concrete in the beam and the reinforcement bars. The bars are disposed in the area of the beam known as the tension area when the beam is subjected to a bending stress to provide tensile reinforcement. | 07-10-2014 |
20140209253 | FLEXIBLE BELT EVAPORATOR - The flexible belt evaporator employs an endless woven textile belt serving as a carrier for saline or otherwise contaminated water for evaporation of the water therefrom, and also serves as the evaporator surface. Mechanical equipment immersed in the saltwater and corresponding maintenance difficulties are largely avoided by placing most or all belt rollers clear of the liquid water tank of the system. Saltwater or contaminated water is sprayed onto the belt from above. The continuing passage of the belt about the exposed rollers results in water evaporation from the belt. Scale and residue buildup on the belt is removed by passing the belt through a wash tank. The wash tank preferably contains an ultrasonic generator to produce ultrasonic energy for removal of residue from the textile belt. The flexible belt evaporator system may be applied to evaporative cooling systems, humidifying systems, and salt or residue recovery systems. | 07-31-2014 |
20140218239 | SINGLE-ANTENNA DIRECTION FINDING SYSTEM FOR MULTI-ROTOR PLATFORMS - The single-antenna radio frequency (RF), direction finding (DF) system includes a single-element directional antenna, which is mounted on a multi-rotor UAV (Unmanned Aerial Vehicle) and integrates with a DF algorithm for tracking an RF source in the 2.45 GHz ISM band (or any other frequency band). The algorithm will depend on the rotating nature of the platform to scan the azimuth, as well as several elevation angles with respect to the platform axis of rotation, and thus be able to accurately locate the coordinates of the RF transmitter based on the recorded power levels. The RF source determination step is performed during the search mode of the algorithm. The RF transmitter location is saved, and the UAV takes actions accordingly by commencing movement towards that location in the action mode of the algorithm. After some time, the UAV enters the search mode again in case the RF source has moved. | 08-07-2014 |
20140219054 | METHOD OF FIRST ARRIVAL PICKING OF SEISMIC REFRACTION DATA - The method of first arrival picking of seismic refraction data is embodied in software that uses the τ-p transform on energy-ratio seismic records. First, the seismic shots are gathered. Next, the energy ratio (ER) is computed, and then the τ-p transform of the energy ratio is computed. Using a binary mask, a corresponding first arrival energy is selected. The transform is combined with the binary mask and presented as input to an inverse τ-p transform. The inverse transform data is then thresholded, and indices of ER first arrivals are detected based on the thresholds. The software then creates a vector of indices or time samples of picks. This method can be used to better guide the subsequent careful picking of first arrivals. Moreover, the method automatically interpolates missing picks. | 08-07-2014 |
20140249284 | CROSS-LINKED POLYAMINOCARBOXYLATES FOR THE REMOVAL OF METAL IONS FROM AQUEOUS SOLUTIONS - The cross-linked polyaminocarboxylates for the removal of metal ions from aqueous solutions of the present invention are cross-linked anionic polyelectrolytes CAPE 6 and CAPE 9, containing pH-responsive amino acid residues. The cross-linked anionic polyelectrolytes have been synthesized via cycloco-polymerization and ter-polymerization of a diallylammonioethanoate monomer (90 mol %) and a cross-linker, 1,1,4,4-tetraallylpiperazinium dichloride (10 mol %) in the absence of SO2 (CAPE 6) and in the presence of SO | 09-04-2014 |
20140306451 | ADAPTIVE PITCH CONTROL SYSTEM FOR WIND GENERATORS - The adaptive pitch control system for wind generators is utilized in variable speed doubly fed induction generator (DFIG) systems. An adaptive neural network generates optimized controller gains for pitch control. The pitch controller parameters are generated using intelligent differential evolution, a type of genetic algorithm. A back propagation neural network is trained using the generated pitch controller parameters, thereby tuning the weights of the network according to the system states in a variable wind speed environment. | 10-16-2014 |
20140310326 | ADAPTIVE FILTER FOR SYSTEM IDENTIFICATION - The adaptive filter for system identification is an adaptive filter that uses an algorithm in the feedback loop that is designed to provide better performance when the unknown system model has sparse input, i.e., when the filter has only a few non-zero coefficients, such as digital TV transmission channels and echo paths. In a first embodiment, the algorithm is the Normalized Least Mean Square (NLMS) algorithm in which the filter coefficients are updated at each iteration according to: | 10-16-2014 |

20140333376 | SCALABLE DIGITAL PREDISTORTION SYSTEM - The scalable digital predistortion system provides a behavioral model that can be used to model and compensate for the nonlinear distortions of power amplifiers and transmitters. The predistorter and update algorithms make the model/DPD scalable in terms of signal bandwidth and average power, allowing for low complexity update following changes in the signal's bandwidth and/or power level. Experimental validation carried on a 300 Watt Doherty power amplifier shows that the scalable model and the predistorter architecture achieve performance similar to their conventional counterpart. However, the present model/predistorter requires the update of up to 50% fewer coefficients than the conventional model/predistorter. | 11-13-2014 |
