  • Patent number: 9589140
    Abstract: The invention provides a digital asset authentication system and method. The invention includes a digital asset metadata register storing details of parties enrolled with the system, including at least one end user and at least one digital asset supplier, and details of digital assets available from the digital asset supplier. A security module is provided for producing a unique tag and for creating a digital asset security container for the tag comprising data relating to events involving the tag, and the tag and the security container are stored in a store. A processor executes authentication software in response to a request from said one end user for a respective digital asset to validate the request by reference to the metadata register to verify that the metadata register lists said one end user and the respective digital asset.

  • Patent number: 6316721
    Abstract: A shielding device is formed by a wall having a top edge arranged to fasten a foil comprising an electrically conducting material. In order to fasten the foil, the wall can be provided with teeth at its top section. Also the wall(s) can be formed with arbitrary angles with respect to each other when forming a whole shielding device. The cover can be formed by one large or several smaller pieces. The cover is fastened to the walls by means of an adhesive, glue or soldering and an electrical contact is provided by the teeth projecting from the wall(s).

  • Patent number: 6222500
    Abstract: The present invention relates to an impedance-matching device of antenna units, and in particular to antenna-matching in small radio units. An impedance-matching device is arranged in a radio equipment having an antenna, between said antenna and a feeding unit, e.g. an output power unit, the impedance quotient of which units exceeding a factor 3. The invented impedance-matching includes at least two quarter-wave transformers connected in series, which consist of a dielectric material having a dielectric coefficient ∈, the value of which is exceeding a factor 10. The device may be made with dimensions so small that it may be integrated with the antenna to an antenna unit and despite the small dimensions, good frequency characteristics are achieved, such as good precision, easy tuning and sufficiently broad bandwidth.
