Abstract: A system and a method for measuring leakage current in an electrical transmission network. The system contains a plurality of electric current measurement devices distributed along the electrical transmission network and at least one central controller. The current measurement devices measure the electric current substantially continuously or repeatedly and report to the central controller. The central controller performs analysis of the measurements of the electric current along the transmission network and calculates the leakage current.

Abstract: A method and apparatus for reliably and accurately matching tooth color, in which a light source is provided with an illumination lens and a relay lens to direct light to illuminate a measurement point in a chosen zone of a tooth selected in a patient's mouth. Light reflected from the tooth is passed through a third lens which focuses the reflected light simultaneously on three detectors. Each detector is provided with a color filter positioned in front of it to allow for only one of the basic red, green and blue (R,G,B) colors to reach the detector. The three detectors produce an output signal representing the R,G,B color coordinate related to the measurement point. These signals are converted to digital data suitable to be further processed by a data processing and control unit, which maps the R,G, B values into values of Hue, Saturation and Intensity (H, S, I) which are normalized to represent a tooth color vector. The process is repeated for a total of three zones on the tooth, developing a color vector set for comparison with a predetermined color vector set to match the closest color vector, allowing the tooth color to be classified as corresponding to one of the colors in the Master Teeth Set.
