  • Patent number: 5933355
    Abstract: A power line ampacity system called LINEAMPS is invented by object oriented modeling and expert rules of the power line environment. Ampacity is estimated by the solution of conductor temperature differential equations using synthetic generation of meteorological data adjusted to national weather service forecast. The line ampacity system provides hourly values of present and future power line ampacity up to seven days in advance. The program has steady state, dynamic and transient ampacity models which can accurately respond to any weather condition or line currents. The system does not require real time meteorological data, conductor temperature measurements or new hardware on power lines. In the absence of real time meteorological data the system generates power line ampacity from the stored weather patterns of the region located in the weather station objects. LINEAMPS is applicable to all overhead power lines and is easily implemented in all geographic regions.

  • Patent number: 5825670
    Abstract: The present invention allows for calibration of a scanning probe microscope under computer control. The present invention comprehends either the removal of nonlinear artifacts in the microscope output data after measurement has been taken (a off-line process), or the correction of nonlinear movements in the microscope scanner such that the scanner moves in a linear fashion during measurement (a realtime process). The realtime process may be operated in both an open-loop and a closed-loop process. The processes of the present invention uses an average cross-section of the scan in order to simplify the calculation and to improve the signal-to-noise ratio. Interpolation methods and centroid calculations are used to locate features on the scanned sample to subpixel precision.

  • Patent number: 5826018
    Abstract: A method and apparatus are disclosed for determining the starting location and starting protocol of LAN data in a WAN frame. A list of offsets and a list of LAN protocols are maintained. For each offset in the offset list, the WAN frame is parsed beginning at the offset and each LAN protocol in the LAN protocol list is looked for, one at a time. If no LAN protocol is recognized to begin at this offset, the next offset in the offset list is chosen and all of the LAN protocols are tried once again beginning at the newly-chosen offset. This process is repeated until all of the LAN protocols are tried at all of the offsets, or until a LAN protocol is recognized. If a LAN protocol is recognized, the offset at which the protocol was recognized is reported, together with the identity of the LAN protocol that was recognized at the offset. If a LAN protocol is not recognized, an appropriate error message is reported.

  • Patent number: 5812404
    Abstract: A method for the continuous overall regulation of a single-layer or multi-layer headbox of a paper, board or pulp-draining machine. A physical fluid flow model of a pulp suspension flow discharged from the headbox to be regulated is formed and solved to obtain a simulated flow state based, e.g., on data on the geometry of the headbox and initial and boundary conditions related to the headbox. A target flow state based on the quality requirements of the paper produced from the pulp suspension flow and the costs of operation and runnability of the machine is obtained and a difference between the simulated flow state obtained as the solution of the flow model and the target flow state is determined. This difference constitutes a cost function which is optimized to determine optimal regulation values and set values for instrumentation devices and actuators of the headbox which affect the pulp suspension flow.

  • Patent number: 5801962
    Abstract: A method and apparatus for calibrating an image system is disclosed. The method according to the present invention includes inputting data by scanning a plurality of lines into a computer, and analyzing the input data for generating intensity of the scanned lines. The inputting step is repeated when the intensity is less than a low threshold value or the intensity is higher than a high threshold value. Next, any scanned line that includes at least a special point is filtered out. After averaging the corresponding points of the scanned lines not filtered out in order to generate a calibration line, a predetermined number of points of the calibration line are averaged to generate a reference point, wherein the predetermined number of points of the calibration line are brighter than other points of the calibrated line. Finally, the calibration data are obtained by taking ratio of the reference point to each of the points of the calibration line.

  • Patent number: 5796628
    Abstract: Given the current operating condition of a power-generating system (obtained from real-time data), the near-term (e.g., after 25 min.) load demand at each bus (obtained from short-term load forecast) and the generation dispatch (based on economic dispatch), a load margin measure (MW and/or MVAR) is determined in order to assess the system's ability to withstand the forecasted load and generation variations. The invention has a method to predict near-term (e.g., after 25 min.) system voltage profiles. The proposed look-ahead measure and/or the system voltage profiles are then applied to contingency selections for the near-term power system, in terms of load margins to collapse and bus voltage magnitudes. The proposed load margin measure and the voltage profiles are based on the power flow technique and the saddle-node bifurcation theory.

  • Patent number: 5784284
    Abstract: A data acquisition device permits plotting of cylinder firing cycles, of varying-frequency, on a fixed-plot area of a CRT screen. Each cylinder firing cycle is sampled, at a constant sample rate, and consecutive sets of sample points, each containing a fixed number of sample points, is generated. On the basis of a unique data reduction technique triggered after the collection of each consecutive sample-point set, certain of the sample points considered superfluous are deleted from the set and the remaining appended to a temporary buffer. The sample-points in the temporary buffer further undergo reduction of the sample points when certain conditions occur, such as buffer full, at which time certain ones are discarded and others are kept. At the end of a cylinder firing cycle, the remaining points are further reduced and a final-set is generated, representative of a full cylinder firing waveform, consisting of sample points equal in number to the plot-width of the CRT screen.
