    摘要： 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.

    摘要： Block copolymer having improved compression set comprising 40-98 wt-% soft segment, 1.9-20 wt-% hard segment, and 0.05-3 wt-% monofunctional ionic endgroups. The incorporation of ionomers into diisocyanate-based thermoplastic polyurethane materials greatly improves compression set with little impact on the overall TPU formulation. A typical formulation for making the block copolymer contains 84.2% polydimethylsiloxane, 12.9% diisocyanate, 2.9% diamine chain extender, 0.15% sodium 2-[bis(2-hydroxyethyl)amino]ethylsulfonate, and 0.05% isethionic acid. The polymeric material may be configured, for instance, as a contact lens, prosthetic spinal nucleus, orthopedic bearing surface, gasket, or sealant.
