  • Patent number: 6499504
    Abstract: The present invention is a more efficient compressor control system and a more efficient method of operating a multiple compressor system because the method and control system are a function of both the system pressure and the volumetric flow rate capacity of the system. Specifically, a compressor is loaded or unloaded from the compressor system after sensing the actual system pressure and volumetric flow rate capacity. The inventor(s) of the present invention have discovered that it is more efficient to control the compressors upon sensing both the pressure and volumetric flow rate capacity of the fluid. Moreover, controlling the compressor system in response to sensing both the pressure and volumetric flow rate capacity of the fluid insures that the appropriate blend of compressors is loaded to the system in order to produce the most suitable pressure and volumetric flow rate capacity.

  • Patent number: 6453079
    Abstract: A document image that is the source of Optical Character Recognition (OCR) output is displayed. Recognition confidence parameters are determined for regions of the document image corresponding to words in the OCR output. The regions are displayed in a manner (e.g., highlighted in various colors) that is indicative of the respective recognition confidence parameter. Preferably, a user can select a region of the displayed document image. When the region is selected, text of the OCR output corresponding to the selected region is displayed in a pop-up menu.

  • Patent number: 6430559
    Abstract: A novel approach for filtering documents involves the use of delivery ratio threshold setting technique to set an initial profile score threshold and the use of beta-gamma regulation for dynamic threshold updating. A group of documents is scored pursuant to a user profile. The score for each document is indicative of the relevance of the corresponding document to the user profile. The score can be compared with a profile score threshold to decide if the document should be accepted or rejected. According to one aspect of the invention, the initial threshold is set to a score threshold that approximates an expected ratio of acceptable documents calibrated with respect to a set of reference documents. According to another aspect of the invention, the score threshold can be updated based on the accumulated example documents, user's relevance judgment, and the user's utility function. The accumulated example documents are first scored against a profile and a ranked list of scored documents is obtained.
