    Abstract: Rapid characterization and screening of polymer samples to determine average molecular weight, molecular weight distribution and other properties is disclosed. Rapid flow characterization systems and methods, including liquid chromatography and flow-injection analysis systems and methods are preferably employed. High throughput, automated sampling systems and methods, high-temperature characterization systems and methods, and rapid, indirect calibration compositions and methods are also disclosed. In preferred high-temperature embodiments, the polymer sample is maintained at a temperature of not less than about 75° C. during sample preparation, loading into a liquid chromatography or flow-injection analysis system, injection into a mobile phase of a liquid chromatography or flow-injection analysis system, and/or elution from chromatographic column. The described methods, systems, and device have primary applications in combinatorial polymer research and in industrial process control.

  • Patent number: 5940594
    Abstract: The present invention is directed to a method and system for storing and managing objects, such as binary large objects (blobs) in a digital library system which includes a plurality of clients, an object server for storing an object, a cache server for storing an copy of the object, and a centralized server for storing information identifying the object as being stored in the object server and associating one or more of the clients with the cache server, in which one of the clients, as a requesting client, requests retrieval of an object, a copy of the requested object is sent from the cache server to the requesting client if the object is stored in said cache server, and a copy of said object is sent from the object server to said requesting client if the object is not stored in the cache server; and a copy of the requested object is sent from the object server to the cache server after the object server sends the object to the client, in which the object sent to the client is made available to the client r

  • Patent number: 5802524
    Abstract: The invention relates to directing one or more object-based search engines to an object store, which stores information archived according to parametric classifiers. In order for the object-based search engine to access the objects, a special index class, in the form of a SQL table is created. The index class comprises attributes of a part number, an object identification number, an item identifier, a search state attribute, and a search engine identifier, an object being assigned a corresponding value for each attribute and each object being uniquely identified by the item identifier attribute. The search engine is activated depending on the type of data object to be indexed, in accordance with the search state attribute the catalog table. A computer readable medium is provided with program code to implement the above integration.

  • Patent number: 5737500
    Abstract: The present invention is a mobile redundant dexterous manipulator with a seven-degree-of-freedom robot arm mounted on a 1 degree-of-freedom mobile platform with a six-degree-of freedom end effector including a real-time control system with multiple modes of operation. The manipulator-plus-platform system has two degrees-of-redundancy for the task of hand placement and orientation. The redundancy resolution is achieved by accomplishing two additional tasks using a configuration control technique. This mobile manipulator with control system allows a choice of arm angle control or collision avoidance for the seventh task, and platform placement or elbow angle control for the eighth task. In addition, joint limit avoidance task is automatically invoked when any of the joints approach their limits. The robot is controlled by a processor employing a 6-by-7 Jacobian matrix for defining location and orientation of the end effector.
