  • Patent number: 8274263
    Abstract: The battery saver includes a charge pump connected to a control switch to provide a time-hysteretic threshold feature wherein it takes a longer, elapsed time threshold to activate the control switch than it does to deactivate the control switch. Control switch output is connected to a main switch wherein activation of the control switch opens the main switch to de-energize a battery-powered device's battery circuit. Control switch deactivation closes the main switch, which energizes the battery circuit of the battery-powered device. A quick elapsed time threshold allows a vibration sensor, which indicates continuing use of the battery-powered device, to instantaneously deactivate the control switch when vibrations are sensed. When the vibration sensor no longer senses motion in the device, a longer elapsed time threshold is triggered in which the charge pump slowly ramps up current to activate the control switch to turn the battery-operated device off.

  • Patent number: 8263000
    Abstract: The apparatus for measuring concentrations of fuel mixtures using depth-resolved laser-induced fluorescence is a fluorometer equipped with a sample container holder that is movable in the path of the beam from the light source. Fluorescent emissions from the sample mixture pass at 90° to the excitation light path through a slit that is narrow enough that the emission intensity is effectively produced by a thin layer of the sample and focused on a monochromator, with successive thin layers receiving nonuniform excitation radiation due to reduction of intensity along the excitation light source path with increasing depth penetration and due to reabsorption of emitted fluorescence from adjacent layers. The method has a first mode in which the emission spectrum is scanned at a fixed depth, and a second mode in which the sample is moved relative to the emission monochromator slit to vary the depth while keeping the emission wavelength fixed.

  • Patent number: 8260732
    Abstract: The computerized method for identifying Hammerstein models is a method in which the linear dynamic part is modeled by a space-state model and the static nonlinear part is modeled using a radial basis function neural network (RBFNN). Accurate identification of a Hammerstein model requires that output error between the actual and estimated systems be minimized. Thus, the problem of identification is an optimization problem. A hybrid algorithm, based on least mean square (LMS) principles and the Subspace Identification Method (SIM) is developed for the identification of the Hammerstein model. LMS is a gradient-based optimization algorithm that searches for optimal solutions in the negative direction of the gradient of a cost index. In the method, LMS is used for estimating the parameters of the RBFNN. For estimation of state-space matrices, the N4SID algorithm for subspace identification is used.

  • Patent number: 8256268
    Abstract: The method for measuring porosity of concrete is a vacuum pressure saturation-based method for calculating a porosity value of a sample of concrete. The method includes the steps of first drying a concrete sample and then making a first weight measurement of the concrete sample. Following the first weight measurement, the concrete sample is placed in a vacuum pressure vessel, where the sample is subjected to vacuum. The vacuum pressure vessel and a pressure cell are next filled with water. Water in the pressure cell and vacuum pressure vessel is pressurized, and the sample remains within the pressurized water for twenty-four hours. The sample remains submerged in the vacuum pressure vessel for another twenty-four hour period to achieve equilibrium. A second weight is then taken in the water, and a third weight measurement is taken in air. The porosity is calculated based upon the first, second and third weight measurements.

  • Patent number: 8260648
    Abstract: The design and process scheduling optimization method is a technique that circumvents problems encountered in previous optimization techniques. The method performs comparison against multiple possible outcomes rather than a single-valued benchmark. Pattern Recognition (PR) techniques are utilized to classify the work planned at specified cut-off dates during the planning stage. Classification is used to monitor and evaluate the progress during the construction stage. The PR technique generalizes a virtual benchmark to represent the whole project based on multiple possible outcomes generated at a given cut-off date. The generalization feature offers a potential tool to overcome the problem of variation in the quality of data collected. Patterns are constructed to encode work of the project at different cut-off dates. The present invention utilizes a robust pattern recognition method applied to Critical Path Method (CPM) procedures to monitor and evaluate progress of construction projects.
