  • Publication number: 20160163524
    Abstract: The invention generally relates to zero volt mass spectrometry probes and systems. In certain embodiments, the invention provides a system including a mass spectrometry probe including a porous material, and a mass spectrometer (bench-top or miniature mass spectrometer). The system operates without an application of voltage to the probe. In certain embodiments, the probe is oriented such that a distal end faces an inlet of the mass spectrometer. In other embodiments, the distal end of the probe is 5 mm or less from an inlet of the mass spectrometer.

  • Patent number: 7644014
    Abstract: In an electronic procurement system having a portal server, an Extensible Markup Language (XML) content integration and transformation method and system. The XML content integration and transformation system includes logic for retrieving an “Open Buying on the Internet (OBI)” compliant XML file from a database which is then formatted in response to an electronic purchasing request over the Internet. In one embodiment of the present invention, the client aware XML content transformation system receives an OBI XML file and uses this information to automatically search for data objects related to the OBI XML file content from a database on the Internet and translates the content into a format suitable for internal processing by the XML content integration and transformation logic and delivers it to the purchasing requisitioner over the Internet.

  • Patent number: 7337132
    Abstract: In an electronic purchasing and procurement system having an Extensible Markup Language (XML) content transformation method and system. The XML content transformation system includes logic for identifying XML content from an external database and presenting XML content formatted in response to purchase requests from the users of the electronic purchasing and procurement system. In one embodiment of the present invention, the XML content transformation system receives an in-bound document containing XML content of a first XML data format. The XML content transformation system then maps the XML content of the first XML data format to an internal proprietary second XML data format using the tag information contained in the first XML data format. The second XML data format is subsequently transformed in a third XML data format suitable for delivery to the user in an out-bound documents.
