  • Publication number: 20120172322
    Abstract: Methods of controlling insects include applying at least one spinosyn compound to a locus of a neonicotinoid-resistant insect, such as a strain of Drosophila melanogaster resistant to a neonicotinoid compound. The spinosyn compound may be a mixture of spinosyn A and spinosyn D. The spinosyn compound may cause up to approximately ten times increased mortality in the neonicotinoid-resistant insect compared to an insect susceptible to a neonicotinoid compound.

  • Patent number: 6001981
    Abstract: The compounds of the present invention are prepared directly or indirectly by modifying the compounds that are naturally produced from Saccharopolyspora spinosa. The compounds of the invention have been shown to have activity against insects and mites. The compounds are prepared by modifying the rhamnose sugar, modification of the forosamine sugar, or starting with pseuodoaglycone and then replacement with a nonsugar derivative or different sugar, modification of the 5,6,5-tricyclic and 12-membered macrocyclic lactone part of the compounds naturally produced or of the pseudoaglycone of the natural compounds.

  • Patent number: 5204860
    Abstract: Network terminating terminal apparatus, for use in an Integrated Services Digital Network, comprises a U-interface and a S/T interface. The U-interface allows the integrated terminal apparatus to communicate with a central office directly, without a separate network terminator. Remote terminals may be connected to the network terminating terminal apparatus, via its S/T interface. The network terminating terminal apparatus then serves as a conventional network terminator. The network terminating terminal apparatus includes circuitry for controlling D-channel access by the integrated terminal apparatus. The circuitry detects the framing of the signal received at the U-interface and the D-channel information from the remote terminals and ensures that the D-channel data from the integrated terminal apparatus is supplied to the S/T interface at the appropriate time for insertion into the D-echo channel of the signal returned to the remote terminals.

  • Patent number: 4965811
    Abstract: In some digital communications systems, such as the Integrated Services Digital Network (ISDN), problems may occur in recovering timing from signals generated by several terminals located varying distances from a common transmitter. Timing recovery is facilitated by detecting a marker of a frame transmitted to the several terminal equipments, detecting a corresponding marker receives shortly afterwards from one of the terminal equipments; and sampling the received digital signal at a sampling instant delayed relative to a specific feature of the received marker, for example, a zero crossing immediately following a frame bit. Preferably, the delay between the sampling instant and the occurrence of the specific feature used as a reference point is proportional to the time elapsed between detection of the outgoing or transmitted marker and detection of the incoming or received marker and hence proportional to the round trip propagation time.
