  • Method and apparatus for purifying exhaust gas of vessel and vessel including the same
    Patent number: 12203402
    Abstract: The present invention provides method and apparatus for purifying exhaust gas of a vessel and a vessel including the same, in which a risk for a vessel and crew of being exposed to ammonia gas used to collect carbon dioxide included in exhaust gas emitted from a vessel may be minimized and an ammonia solution may be recycled and reused to collect carbon dioxide, in order to satisfy regulations on discharge of exhaust gas by the IMO. Also, the present invention provides an apparatus 1000 for purifying exhaust gas of a vessel and a method of purifying exhaust gas of a vessel using the same, in which carbon dioxide and sulfur dioxide included in exhaust gas emitted from a vessel may be collected by using a reaction solution and may be changed into a substance that does not affect the environment so as to be stored and transported to land.

  • Device for testing smart card and method of testing the smart card
    Patent number: 7181665
    Abstract: Devices and methods are provided for testing various types of smart cards including contact, contactless, and hybrid type (contact/contactless) smart cards. A test device includes a logic tester, a contactless interface unit, and a contact interface unit. The logic tester generates a test pattern that is transmitted to a smart card to test the smart card and compares a received response pattern with a response pattern to test a status of the smart card. The contactless interface unit enables a contactless test mode of operation and the contact interface unit enables a contact test mode of operation.
