    • Silicone containing reactive monomers with hydrophilic end-groups of formula I useful in the manufacture of biocompatible medical devices are disclosed, wherein R1 is H or CH3, a is 0 or 1, p is an integer from 1 to 6, q is an integer from 1 to 3 and for each q, the end groups R51, R52, R53 are independently an alkyl, alkyl ether, trimethylsiloxy group, or a substituted or non-substituted aromatic group and at least one of them has a hydrophilic group attached, preferably to the terminal end of R51, R52, R53, X is O or NR54, where R54 is H or a monovalent alkyl group with 1 to 4 carbons, n is an integer from 1 to 100, R2 and R3 are independently an alkyl, alkyl ether, or a substituted or non-substituted aromatic group, preferred R2 and R3 include methyl, ethyl, and phenyl, L is a divalent linker comprising substituted and unsubstituted alkylene groups having 1-14 carbon atoms, which may be straight or branched, substituted and unsubstituted alkoxy groups having 2-12 carbons, polyethers, oxazolines, and substituted and unsubstituted heterocyclic groups. Suitable substituents include aryl, amine, ether, amide, hydroxyl groups, combinations thereof and the like. In another embodiment, L comprises a straight or branched alkylene group having 2 to 12 carbons. The reactive monomers combine oxygen permeable silicone components with hydrophilic terminal groups capable of reaching to the device-bio-logic interface thus providing bulk and surface characteristics useful in the manufacture of medical devices, particularly ophthalmic devices.

    • A data communication method includes providing a sender node having a data packet of information. The data packet includes at least one first field and a second field. The second field has content that is dependent upon actual content of the at least one first field. The content of the second field of the data packet is transmitted from the sender node to a receiver node. The receiver node is used to predict the actual content of the first field of the data packet. The receiver node is used to calculate the content of the second field of the data packet based upon the predicted content of the first field. The predicted content of the first field is confirmed to be equivalent to the actual content of the first field. The confirming step includes comparing the calculated content of the second field to the transmitted content of the second field.
    • 数据通信方法包括提供具有信息的数据分组的发送者节点。 数据分组包括至少一个第一场和第二场。 第二字段具有取决于至少一个第一字段的实际内容的内容。 数据分组的第二字段的内容从发送方节点发送到接收方节点。 接收器节点用于预测数据包的第一个字段的实际内容。 接收器节点用于基于第一场的预测内容来计算数据分组的第二场的内容。 确认第一场的预测内容等于第一场的实际内容。 确认步骤包括将计算出的第二场内容与第二场的发送内容进行比较。
