摘要： 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.

摘要： 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).

摘要： 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. In response to a valid request, the processor firstly causes the security module to produce the tag and to create the security container containing data relating to the end user, the digital asset request and the digital asset, and secondly generates a message for said one end user including the tag and authorizing release of said digital asset for download, play or use.
摘要翻译：本发明提供一种数字资产认证系统和方法。本发明包括一个数字资产元数据寄存器，用于存储系统注册的各方的细节，包括至少一个终端用户和至少一个数字资产提供者，以及从该数字资产提供者获得的数字资产的细节。一个安全模块被提供用于产生一个独特的标签，并为标签创建数字资产安全容器，该容器包括与涉及标签的事件相关的数据，标签和安全容器被存储在商店中。处理器响应于来自所述一个最终用户的相应数字资产的请求执行认证软件，以通过参考元数据寄存器来验证该请求，以验证元数据寄存器列出所述一个最终用户和相应的数字资产。响应于有效请求，处理器首先使安全模块产生标签并创建包含与最终用户，数字资产请求和数字资产有关的数据的安全容器，并且其次产生用于所述一端的消息用户包括用于下载，播放或使用的所述数字资产的标签和授权发布。
