  • Patent number: 5726978
    Abstract: A method and system of adaptive channel allocation in a frequency division multiplexed system is provided. In the method and system a subset of M subcarriers is chosen from a larger set of N subcarriers available for communications on a link. As communications take place on the link, signal quality (C/I) measurements on the subcarriers of the subset of M subcarriers and interference (I) measurements on the subcarriers of the group of N subcarriers are periodically performed. The C/I and I measurements are then used to reconfigure the subset of M subcarriers to reduce co-channel interference on the link.

  • Patent number: 5722585
    Abstract: The invention relates to a folding box with self-adhesive seal and a method for sealing the folding box. The folding box has a cover (6) which can be locked in the sealing position at one of its free edges by a mechanical locking (10, 11), flaps (14, 15) that can be folded in under the cover, and contact adhesive strips (17) with covering strips (19) able to be pulled off, for gluing the cover (6) together with the flaps (14, 15). The covering strips (19) have at their free end a tab (19a) that protrudes from the closed folding box. By pulling on the tab (19a), the covering strips (19) can be pulled out laterally under the cover (6) locked in sealing position, in order to glue the cover (6) together with the flaps (14, 15). On perforated tear lines (23), the middle section of the cover (6) can be opened again, without having to undo the adhesive connection in doing so.
