Publication number: 20120041887Abstract: An arrangement for enabling an acting party, e.g. a natural person or an automatic inspection line, to retrieve information from a product (150), e.g. for genuineness verification, includes an optical device (102) for optically receiving auxiliary information from the product, a processing system (103) for retrieving instruction data from a database (104) on the basis of the auxiliary information, and a data interface (105) for delivering the instruction data to the acting party for enabling the acting party to retrieve the information. In the genuineness verification application, the verification is provided with two separate components. A first component resides in the auxiliary information on the surface of the product and a second component resides in the instruction data. The division of the genuineness verification into the two components makes it more difficult for a counterfeit manufacturer to analyze the counterfeit protection and to follow changes in the counterfeit protection.Type: ApplicationFiled: March 29, 2010Publication date: February 16, 2012Applicant: TEKNOLOGIAN TUTKIMUSKESKUS VTTInventors: Eero Hurme, Jouko Hyvakka, Caj Sodergard

Patent number: 6279384Abstract: A method for detecting a leak in a resilient, semi-hard and hard package includes a test gas supplied to the package to subject the contents of the package to a first pressure. The package is then maintained for a predetermined time in a chamber having a gas pressure, and the presence of gas is detected in a measuring space in gas flow relationship with the chamber by a detection apparatus. In order for the method to be rapid enough to be suitable for detecting very small holes in packages and for use in production plants without a change in their operating rate, a hydrogen gas having a hydrogen gas concentration from 0.0001-6% by volume is used as the test gas supplied to the package, and the hydrogen gas concentration of the gas within the chamber is maintained below a reference concentration that is lower than the hydrogen gas concentration in the package immediately after the addition of hydrogen gas to the package.Type: GrantFiled: April 21, 1999Date of Patent: August 28, 2001Assignee: Espoon Paineilma OyInventors: Eero Heikkinen, Eero Hurme, Raija Ahvenainen
