    • A system and method for enhancing the security of signal exchanges in a network system. The system and method include a process and means for generating one or more replacement encryption key sets based on information and events. The information that may cause the generation of a replacement encryption key set includes, but is not limited to, a specified period of time, the level and/or type of signal traffic, and the signal transmission protocol and the amount of data sent. A key manager function initiates the replacement encryption key process based on the information. The replacement encryption key set may be randomly or pseudo-randomly generated. Functions attached to the network system required to employ encryption key sets may have encryption key sets unique to them or shared with one or more other attached functions. The system and method may be employed in a wireless, wired, or mixed transmission medium environment.
    • 一种用于增强网络系统中信号交换安全性的系统和方法。 该系统和方法包括用于基于信息和事件生成一个或多个替换加密密钥集的过程和装置。 可能导致生成替换加密密钥集的信息包括但不限于指定的时间段,信号业务的级别和/或类型以及信号传输协议和所发送的数据量。 密钥管理器功能根据该信息启动替换加密密钥过程。 替换加密密钥集可以是随机或伪随机生成的。 使用加密密钥集所需的附加到网络系统的功能可以具有对它们唯一的或与一个或多个其他附加功能共享的加密密钥集。 该系统和方法可以用于无线,有线或混合传输介质环境中。

    • Multi-purpose solutions for contact lens care provide substantial lens wearer/user comfort and/or acceptability. Such solutions include an aqueous liquid medium; an antimicrobial component, preferably a biguanide polymer present in an amount of less than about 5 ppm; a surfactant component, preferably a poly(oxyethylene)-poly(oxypropylene) block copolymer surfactant, in an effective amount; a phosphate buffer component in an effective amount; a viscosity inducing component, preferably selected from cellulosic derivatives, in an effective amount; and a tonicity component in an effective amount. Such solutions have substantial performance, comfort and acceptability benefits, which, ultimately, lead to ocular health advantages and avoidance of problems caused by contact lens wear.
