  • Patent number: 8280802
    Abstract: A computerized system alerts a change in direction of the price of a tradable financial instrument. The system plots a resistance line, a support line, and a transition point at which the price is changing. The transition point occurs when the price of the tradable instrument is either higher or lower than both the corresponding resistance point on the resistance line and a corresponding support point on the support line. Resistance points are calculated sequentially as the lowest averaged values of a series of critical prices for a particular time period. Support points are calculated sequentially as the highest averaged values of a series of critical prices for a particular time period, wherein the critical prices comprise the highest price, the lowest price, and the closing price of the tradable instrument for that particular time period.

  • Patent number: 8280652
    Abstract: An apparatus, method, and system for measuring the magnetic field produced by phase conductors in multi-phase power lines. The magnetic field measurements are used to determine the current load on the conductors. The magnetic fields are sensed by coils placed sufficiently proximate the lines to measure the voltage induced in the coils by the field without touching the lines. The x and y components of the magnetic fields are used to calculate the conductor sag, and then the sag data, along with the field strength data, can be used to calculate the current load on the line and the phase of the current. The sag calculations of this invention are independent of line voltage and line current measurements. The system applies a computerized fitter routine to measured and sampled voltages on the coils to accurately determine the values of parameters associated with the overhead phase conductors.

  • Patent number: 8274647
    Abstract: A method of classifying a graded-index multimode optical fiber includes taking a series of individual measurements at a single wavelength, and using the measurements to characterize the departure of the multimode optical fiber's actual index profile from the corresponding nominal index profile. The measurements, coupled with intermodal dispersion or EMB measurement, may be used to predict the approximate transmission properties of the optical fiber at wavelengths other than the measurement wavelength.

  • Patent number: 8265442
    Abstract: A bend-insensitive glass fiber with a novel coating system yields exceptionally low losses. The coating system features (i) a softer primary coating with excellent low-temperature characteristics to protect against micro-bending in any environment and in the toughest physical situations and, optionally, (ii) a colored secondary coating possessing enhanced color strength and vividness. The secondary coating provides improved ribbon characteristics for structures that are robust, yet easily entered (i.e., separated and stripped). The optional dual coating is specifically balanced for superior heat stripping in fiber ribbons, with virtually no residue left behind on the glass. This facilitates fast splicing and terminations. The improved coating system provides optical fibers that offer significant advantages for deployment in most, if not all, fiber-to-the-premises (FTTx) systems.
