Publication number: 20240087828Abstract: Microelectromechanical systems (MEMS) switches are disclosed. Parallel configurations of back-to-back MEMS switches are disclosed in some embodiments. An isolation connection of constant electrical potential may be made to a midpoint of the back-to-back switches. In some embodiments, a separate MEMS switch is provided as a shunt switch for the main MEMS switch. MEMS switch device configurations having multiple switchable signal paths each coupling a common input electrode to a respective output electrode are also disclosed. The MEMS switch device includes shunt switches each coupling a respective output electrode to a reference potential. The presence of a shunt switch coupled to an output electrode enhances the isolation of the signal path corresponding to that output electrode when the path is open.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Applicant: Analog Devices International Unlimited CompanyInventors: Padraig Fitzgerald, Philip James Brennan, Jiawen Bai, Michael James Twohig, Bernard Patrick Stenson, Raymond C.

Patent number: 9053437Abstract: Techniques are disclosed for extracting information through analysis of provenance data. For example, a computer-implemented method of extracting information regarding an execution of an enterprise process comprises the following steps. Provenance data is generated, wherein the provenance data is based on collected data associated with an actual end-to-end execution of the enterprise process and is indicative of a lineage of one or more data items. A provenance graph is generated that provides a visual representation of the generated provenance data, wherein nodes of the graph represent records associated with the collected data and edges of the graph represent relations between the records. At least a portion of the generated provenance data from the graph is analyzed so as to extract information about the execution of the enterprise process based on the analysis.Type: GrantFiled: November 6, 2008Date of Patent: June 9, 2015Assignee: International Business Machines CorporationInventors: Sharon C. Adler, Francisco Phelan Curbera, Yurdaer Nezihi Doganata, Chung-Sheng Li, Douglas C. Lovell, Axel Martens, Kevin Patrick McAuliffe, Huong Thu Morris, Nirmal K. Mukhi, Aleksander A. Slominski

Patent number: 8229775Abstract: Techniques are disclosed for capturing, storing, querying and analyzing provenance data for automatic discovery of enterprise process information. For example, a computer-implemented method for managing a process associated with an enterprise comprises the following steps. Data associated with an actual end-to-end execution of an enterprise process is collected. Provenance data is generated based on at least a portion of the collected data, wherein the provenance data is indicative of a lineage of one or more data items. A provenance graph that provides a visual representation of the generated provenance data is generated, wherein nodes of the graph represent records associated with the collected data and edges of the graph represent relations between the records. The generated provenance graph is stored in a repository for use in analyzing the enterprise process.Type: GrantFiled: November 6, 2008Date of Patent: July 24, 2012Assignee: International Business Machines CorporationInventors: Sharon C. Adler, Francisco Phelan Curbera, Yurdaer Nezihi Doganata, Chung-Sheng Li, Axel Martens, Kevin Patrick McAuliffe, Huong Thu Morris, Nirmal K. Mukhi, Aleksander A. Slominski
