  • Patent number: 11747271
    Abstract: A separation device receives a known or unknown glycan that is co-injected with three different oligomers maltooligosaccharide (MOL). A detector measures the separated glycan and the separated three different oligomers as intensity peaks that are a function of migration time. The migration times of a plurality of other oligomers of MOL are calculated from the migration times of the three different oligomers. Glucose unit (GU) values for the intensity peaks of the separated glycan are calculated by comparing their migration times to the calculated migration times of the plurality of other oligomers of MOL. The processor identifies the structure of the glycan by comparing the calculated GU values of the intensity peaks of the separated glycan to a database of GU values for known glycan structures.

  • Patent number: 10026069
    Abstract: A system and method for usage metering software applications (or features or functions) by monitoring the data store underlying the software application. The data store function may be implemented in many ways, such as a Relational Database, Transactional Database, Network and Graph Database, Object-Oriented Database, Embedded Database, In-memory Database, Schema-less Database, Files and Directories, whether structured or unstructured, Configuration Registries, or Non-traditional Repositories. Business activities performed by the software application are tracked and are independent of hardware usage. Such usage data is valuable in a variety of contexts, including billing based on business activity.

  • Patent number: 7490508
    Abstract: An apparatus for testing a cleaning procedure for a material. The apparatus includes a rack having a seat configured to retain a plurality of test coupons at a predetermined angle, an upper tray that distributes a solution along the lines of the rack, a lower tray for receiving solution passed over coupons disposed on the rack, a meter that gauges a flow rate of the solution, a thermostatic heater adapted to bring the solution to a predetermined temperature, and a variable speed pump that directs the solution from a reservoir to the upper tray.
