    摘要： The present invention concerns a silane of formula (1)

    R1aSIR4-a  (1)



    where
    the group R1 or each of the groups R1 independently

    is bound to the silicon via an oxygen atom,
    comprises a straight or branched hydrocarbonaceous chain having one or more elements, wherein
    (a) each of the elements has not more than 8 consecutive carbon atoms, each of plural elements of the hydrocarbonaceous chain being separated from the next element by a cleavable group and/or
    (b) the elements have one or more cleavable groups and any hydrocarbonaceous chains remaining upon cleavage of said group(s) are water soluble,
    wherein said cleavable groups are selected from ester, anhydride, amide, carbonate, carbamate, ketal, acetal, disulfide, imine, hydrazone and oxime groups,
    has at least one thiol or a primary or secondary amino group,


    the group R or each of the groups R is independently a hydrolytically condensable group, and
    a is 1,2,3 or 4.




    The invention further relates to organically modified, polymerized silicic acid polycondensates which have been obtained by reaction and optionally subsequent hydrolytic condensation of such a silane or of silicic acid polycondensates therefrom with a bridging compound, which undergo an addition reaction with the at least one thiol or primary or secondary amino group of the radical R1 of the silane of the formula (1).

    摘要： Communication method, comprising: transmitting at least one data packet with a header and a coded packet, wherein the header includes, from a group, at least one first information relevant for interpreting the coded packet, wherein the group includes one or several of the following information: —information with respect to one or several sources of the coded packet and information with respect to one or several sinks of the coded packet or information with respect to one or several sources or sinks of the coded packet in combination with information with respect to a transmission direction or with respect to one or several further communication partners; —a coding vector, wherein the coding vectors is included separately, included integrally, pre-specified, or referenced, wherein coding coefficients are allocated to the coding vector; and deriving, from the at least one first information under consideration of pre-configured information, one second information of the group that is relevant for interpreting the coded packet.
