US Classification:

706 50, 345347

Abstract:

A multi-user system for creating and maintaining a knowledge base is implemented on a variety of computer systems, including single-user personal computers, networked personal computers, and data communications networks, including the Internet. The system has a graphic user interface which can be easily learned by non-programmers. The knowledge base is displayed as a hierarchical multiplicity of nodes, in which each node is related to one or more superior nodes. Title of text, rules, references, and attributes associated with each node are displayed, and may be modified. Simulation is used to verify the knowledge base once generated. Data may be extracted from the bases in the form of hard-copy books, databases for downloading into Web browsers, and databases for downloading into hand-held computers including a multiplicity of grids, and a multiplicity of branches in the form of a logic tree. The user may choose one of the alternative display formats, and the hierarchy can be displayed in either collapsed view or expanded view. Interference between two or more users accessing the system concurrently is prevented by a locking and authorization subsystem, which also prevents unauthorized access to the environment.

International Classification:

G01N 3116

US Classification:

422 75

Abstract:

A fluorometric titrator has means to transfer a pipette between first and second positions and a buret for a chelating agent has a reversible drive powered either by a pulse generator or an oscillator. Valve controlled means are operable to place the buret in communication with the pipette or a reservoir. In the first position of the pipette, a precise sample volume is aspirated into it by the buret, then driven by the oscillator and in its second position and with the buret drive reversed but still powered by the oscillator, the sample volume is discharged from the pipette into a cuvette in the fluorometer. On the resulting fluorescence the fluorometer output drives the pulse generator to dispense chelating agent and to operate a counter until a selected end point is reached. The pipette is then returned to its second position with the buret drive again operated by the oscillator and during the return, the buret is refilled. Both before the sample volume is aspirated, and before that volume is discharged, backlash is removed from the buret drive.

International Classification:

G06F 1700

US Classification:

706 45

Abstract:

A System for screening of medical decision making is described. The system runs on a personal computer, and incorporates a knowledge base containing the data required to perform the screening, as well as the rules to be incorporated. The knowledge base is organized into criteria sets subdivided into categories, which include clinical specialties, such as surgery, and imaging, or a level of care, or a body system. The criteria sets are further subdivided into interventions, review types, and levels of care. Finally, within each subdivision, the user selects criteria points which are representations of the patient's clinical condition. Upon selection of the criteria points, the system will indicate whether or not a selected method of treatment is medically appropriate or not. The review process is recorded for subsequent examination.
