  • Publication number: 20240152885
    Abstract: Methods and systems are presented for providing a framework to securely integrate third-party logic into electronic transaction processing workflow. Third-party programming code that implements different third-party logic may be obtained and stored in a repository. A transaction processing request is received from a third-party server, and an instance of a transaction processing module is instantiated within an operating runtime environment to process a transaction according to a workflow. When the instance of the transaction processing module has reached an interruption point, the instance of the transaction processing module is suspended, and a third-party programming code is executed within an isolated runtime environment. The third-party programming code is configured to provide an output value based on attributes of the transaction. The instance of the transaction processing module then determines whether to authorize or deny the transaction based in part on the output value.

  • Publication number: 20050193946
    Abstract: A vacuum process apparatus for preventing corrosion of a vacuum gauge is disclosed. The apparatus includes a process chamber used to proceed a vacuum process reaction. A vacuum gauge is connected to the process chamber. A protective gas source without water vapor which supplies a protective gas without water vapor into the process chamber to break vacuum in the process chamber after the vacuum process reaction within the process chamber is over. An isolation device between the process chamber and the vacuum gauge is actuated to isolate the process chamber from the vacuum gauge in an atmospheric pressure state caused by the protective gas without water vapor to avoid a pressure differential between the process chamber and the vacuum gauge.
