    • Systems and methods are disclosed for performing duplicate document analyses to identify texturally identical or similar documents, which may be electronic documents stored within an electronic discovery platform. A process is described which includes representing each of the documents, including a target document, as a relatively large n-tuple vector and also as a relatively small m-tuple vector, performing a series of one-dimensional searches on the set of m-tuple vectors to identify a set of documents which are near-duplicates to the target document, and then filtering the near set of near duplicate documents based upon the distance of their n-tuple vectors from that of the target document.

    • An electronic ballast for driving a gas discharge lamp includes an EMI filter, a bridge rectifier coupled to a DC bus without a conventional electrolytic capacitor, a passive valley fill circuit built as a network having 4 charge/discharge energy storage capacitors and 9 diodes (4C9C), and a resonant DC to AC high frequency inverter for powering gas discharge lamp. The 4C9D circuit divides the rectified peak voltage by four and the low output voltage of the circuit is used to provide continuous lamp operation. The result is a ballast having substantially improved power factor, total harmonic distortion, and current crest factor. The electronic ballast is provided with a dimming capability from a TRIAC based wall dimmer.

    • This disclosure concerns a cleaning and inspection system for fiber optics that is rapid, reliable and useful for various types of fiber optics. In an embodiment, the system includes a wide field of view (FOV) camera to image the ferrule and rapidly locate the fiber ends and a narrow FOV camera to provide detailed inspection of fiber ends. A cleaning module with a cleaning tip and a cleaning media that is drawn through the tip is used to clean the fiber ends. Images captured by the dual cameras are automatically enhanced and analyzed to determine the effectiveness of the cleaning process and to identify the types and quantity of defects present. In another embodiment, a single higher resolution camera is provided with a lens that can image an entire fiber array and yet enable defects to be detected by analysis of sub-images of each fiber in the fiber array.
