  • Patent number: 6561719
    Abstract: A signal generator is suggested for a mounting on holding tubes, having a base element for being placed on the holding tube and a fastening element for fixing the base element on the holding tube, which requires low expenditures during the manufacturing and ensures a reliable fixing. According to the invention, this is achieved in that the fastening element cuts form-lockingly into the material of the holding tube (4) and of the base element (1).

  • Patent number: 5359166
    Abstract: A keyboard for electronic equipment screens off RF radiation by using a conductive housing (2), preferably made of extruded aluminum, which is closed off at its two ends by conductive end pieces (25) and which is closed off underneath by a conductive base plate (30). Key switches (9) extend through openings in a conductive frame (15) that is mounted inside the housing (2), which itself has openings (5, 6) for passage of the key switches (9). The elements are configured to reduce the level of any RF radiation that escapes from inside the keyboard. Among other advantages, this reduction of escaping RF radiation prevents illicit detection and decoding of information which is being entered via the keyboard.
