Patent number: 8178356Abstract: Naturally present chloride concentration in natural water is utilized for the development of the technique to gauge the performance of percolation tanks in space and time. The chloride mass balance technique is simple, sensitive, reliable and yet powerful enough to resolve the temporal variation due to the effect of silting or climate factors.

Patent number: 8180577Abstract: Techniques for determining effects on a biological system include determining rate constants for a particular time interval starting at an initial time. Each rate constant indicates a rate of transition from one of four states to a different one of the four states for a component of a biological system in presence of an external factor. A temporal change in a probability that the component is in a particular state after the initial time is determined without numerical iteration over multiple time steps. This includes determining three relaxation time constants that describe exponential changes based on the rate constants. The effect of the external factor on the biological system is determined based on the temporal change in the probability that the component is in the particular state. The probability at an arbitrary time is determined based on the rate constants and initial probabilities.Type: GrantFiled: December 17, 2010Date of Patent: May 15, 2012Assignee: University of Maryland, BaltimoreInventor: Lawrence Goldman

Patent number: 8175815Abstract: The invention deals with a method for the assessment of the effect of excipients, pH and combinations thereof on the predicted absorption properties of low solubility compounds, comprising the step of assessing a change in a flux function for a combination of a low solubility compound and an excipient at at least one predefined pH value. The method allows a fast, accurate, and economic evaluation of an excipient being capable of optimizing the absorption of drug molecules, i.e. low solubility compounds. Furthermore, animal experiments can be excluded and use of compounds can be reduced in such evaluation. Thus, screening for future formulation efficacy (pH and excipient effects on solubility and permeability) of drug candidates can be justified, since the method is fast, compound-sparing, cost-effective, and reasonably accurate.Type: GrantFiled: February 27, 2007Date of Patent: May 8, 2012Assignees: F.

Thus, the present invention enables a user to analyze a series of complex data sets in a visual display that may indicate the presence of the selected metabolites across the group of samples. Furthermore, the visual display generated by embodiments of the present invention also expedites the subjective analysis of the spectrometry data sets.Type: GrantFiled: April 12, 2011Date of Patent: May 8, 2012Assignee: Metabolon Inc.Inventors: Thomas Henry Barrett, Jr., Corey Donald DeHaven, Danny C.

Patent number: 8160730Abstract: A control system (300) for optimizing a power plant includes a chemical loop having an input for receiving an input signal (369) and an output for outputting an output signal (367), and a hierarchical fuzzy control system (400) operably connected to the chemical loop. The hierarchical fuzzy control system (400) includes a plurality of fuzzy controllers (330). The hierarchical fuzzy control system (400) receives the output signal (367), optimizes the input signal (369) based on the received output signal (367), and outputs an optimized input signal (369) to the input of the chemical loop to control a process of the chemical loop in an optimized manner.Type: GrantFiled: February 27, 2009Date of Patent: April 17, 2012Inventor: Xinsheng Lou

Patent number: 8158436Abstract: The invention provides methods and apparatus for characterizing complex polymeric mixture of interest. Candidate solutions are eliminated from a solution space using one or more experimental measurements of a polymeric mixture of interest. The elimination step can be repeated one or more times using different experimental measurements produced by various chemical and physical protocols, so that the remaining candidate solutions converge to describe the actual polymeric mixture under investigation. Once the composition of the complex polymeric mixture has been characterized, the information thus generated can be used to facilitate, for example, the manufacture of a bio-equivalent of the complex polymeric mixture.Type: GrantFiled: September 3, 2010Date of Patent: April 17, 2012Assignee: Momenta Pharmaceuticals, Inc.Inventor: Sasisekharan Raguram

Patent number: 8160820Abstract: Scoring functions can be markedly improved by taking into account the status environs of ligand rings (or indeed other bulky rigid ligand structures) on the ligand when the ligand is complexed with the receptor. In its most general form, the invention features, quantifying a particular component of binding affinity between a ligand and a receptor molecule. Specifically, the component in question takes into account the spatial relationship between ligand ring structure(s) (or bulky rigid ligand structures) and their ambient surroundings when the ligand is bound to the receptor molecule. The method steps may be used when quantifying a component that reflects these particular ligand features alone, or the steps may be part of a comprehensive method of quantifying binding affinity which includes numerous other factors that relate to binding affinity in addition to the component.Type: GrantFiled: May 12, 2008Date of Patent: April 17, 2012Assignee: Shrodinger, LLCInventors: Richard A. Friesner, Robert Murphy

Patent number: 8154399Abstract: A CBRNE detection system and method for operating same are disclosed. The method provides a relatively increased Probability of Detection and a relatively decreased Probability of False Alarms for a networked system of detectors. In the illustrative embodiment, a central controller of the system is capable of receiving information from individual CBRNE detectors and of determining whether or not to issue an alarm indicating that a CBRNE event has occurred. Data obtained from individual CBRNE detectors is evaluated based on one or more “sensor alert-to-system alarm” processing modes. The various processing modes specify the requirements that must be satisfied before a system-wide “alarm” is issued.Type: GrantFiled: March 10, 2009Date of Patent: April 10, 2012Assignee: Lockheed Martin CorporationInventors: Francesco Pellegrino, Thomas J. Psinakis, Raymond Morrissey, Robert D'Italia, Edward J. Vinciguerra, Kevin J. Tupper, Marie Catherine Bruzzi
