  • Patent number: 8522326
    Abstract: A system for authentication comprises a mobile unit and a smart card reader. The mobile unit includes a security application that prevents access to functionalities and data stored thereon and further includes an authentication application that securely stores an authentication token. The smart card reader communicatively connects to a smart card. The smart card includes authentication data. The authentication application transmits the authentication token to the smart card reader to verify the smart card. The authentication application shares the authentication token with the security application when the verification is successful. The authentication token indicates to the security application to grant access to the functionalities and the data.

  • Patent number: 7384041
    Abstract: A document transfer buffer device for holding temporarily a document between an upstream document feeding device and a downstream envelope inserter has a transporting device for moving the document from the upstream document feeding device to the envelope inserter and an envelope holding device for temporarily holding the document in a holding location between the upstream document feeding device and the envelope inserter and a controlling program that selectively activates the transporting device and the temporary holding device and is responsive to the upstream feeding device and the envelope inserter possible error conditions that initiate document holding and releasing situations.
