  • Patent number: 11309630
    Abstract: An antenna for a communication device is disclosed. The antenna has a structure including a ground plane and a lid component. The lid component is conductive, substantially planar and has a planform shape which is lesser in a first lid component dimension (L1) than it is in a second lid component dimension (L2) perpendicular to the first lid component dimension (L1). The ground plane is conductive and substantially planar, and the size of the ground plane is greater than the size of the lid component. The lid component is conductively connected to the ground plane but also spaced apart from the ground plane, such that there is a space between the lid component and the ground plane, and the antenna is center fed.

  • Publication number: 20210387582
    Abstract: Licence plates with a data medium and a slot antenna have low transmission and reception performance for electromagnetic waves as a rule. Moreover, the positioning of the slot antenna is severely limited by an inscription on the licence plate. The invention provides a licence plate with a data medium and an antenna with improved transmission power and at the same time sufficient space for the positioning of the antenna. This is achieved by a licence plate body of the licence plate having at least one cavity, and a front of the licence plate body or a coating of the front of the licence plate body covering the cavity comprises a slot structure forming the antenna.

  • Patent number: 8131642
    Abstract: A method of controlling the value of at least one on-line transaction involving a token associated with an authorized user comprises the steps of: prior to the at least one proposed transaction, receiving at a pre-transaction authorization station, pre-transaction authorization data. The authorization data comprises first time data relating to a time window within which the at least one proposed transaction must take place and first amount data relating to an amount with which a value of the at least one proposed transaction must comply. Substantially at the time of a proposed transaction, transaction data comprising second time data relating to a time instant of the proposed transaction and second amount data relating to a value of the proposed transaction is received at the authorization station. The authentication data and transaction data are compared in real time at 34 and only if the transaction data complies with the authorization data, is the transaction enabled.

  • Patent number: 7360081
    Abstract: A method of authenticating an article includes the steps of, at an issuing station, selecting an inherent feature of the article and converting the feature into digital data to form an identification code for the article. An encryptor is used to encrypt the identification code utilizing a secret private key of an asymmetric encryption key pair and associated with the issuing party. The encrypted code is made available on a label accompanying the article. During a subsequent phase and at an authentication station, digital data relating to the feature is determined directly from the article and the code is decrypted utilizing a public key of the pair obtained from a third party in accordance with rules of a public key infrastructure. The determined data and the data relating to the feature retrieved from the decrypted code are compared to authenticate the article.
