  • Patent number: 8124436
    Abstract: A MEMS switch with a platinum-series contact is capped through a process that also passivates the contact by controlling, over time, the amount of oxygen in the environment, pressures and temperatures. Some embodiments passivate a contact in an oxygenated atmosphere at a first temperature and pressure, before hermetically sealing the cap at a higher temperature and pressure. Some embodiments hermetically seal the cap at a temperature below which passivating dioxides will form, thus trapping oxygen within the volume defined by the cap, and later passivate the contact with the trapped oxygen at a higher temperature.
    Type: Grant

    Date of Patent: February 28, 2012
    Assignee: Analog Devices, Inc.

  • Publication number: 20110138055
    Abstract: The present application provides a scalable system for managing requests for compute resources using a cloud computing architecture. The system estimates the total processing time of each computation in advance and monitors the progress of each computation to provide a more accurate estimate of remaining processing time. In this way, a determination may be made as each new computation request is received as to whether an additional resource is required or whether an existing resource would be suitable.
