    • 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。

    • Performance and reliability of microelectromechanical system (MEMS) components enhanced dramatically through the incorporation of protective thin film coatings. Current-generation MEMS devices prepared by the LIGA technique employ transition metals such as Ni, Cu, Fe, or alloys thereof, and hence lack stability in oxidizing, corrosive, and/or high temperature environments. Fabrication of a superhard, self-lubricating coating based on a ternary boride compound AlMgB14 is described in this letter as a potential breakthrough in protective coating technology for LIGA microdevices. Nanoindentation tests show that hardness of AlMgB14 films prepared by pulsed laser deposition ranges from 45 GPa to 51 GPa, when deposited at room temperature and 573 K, respectively. Extremely low friction coefficients of 0.04-0.05, which are thought to result from a self-lubricating effect, have also been confirmed by nanoscratch tests on the AlMgB14 films. Transmission electron microscopy studies show that the as-deposited films are amorphous, regardless of substrate temperature; however, analysis of FTIR spectra suggests that the higher substrate temperature facilitates formation of the B12 icosahedral framework, therefore leading to the higher hardness.
    • 微机电系统(MEMS)组件的性能和可靠性通过并入保护性薄膜涂层而显着提高。 通过LIGA技术制备的当前一代MEMS器件采用过渡金属如Ni,Cu,Fe或其合金,因此在氧化,腐蚀性和/或高温环境中缺乏稳定性。 在本文中描述了基于三元硼化物AlMgB 14的超硬自润滑涂层的制造,作为LIGA微型器件的保护涂层技术的潜在突破。 纳米压痕测试显示,当分别在室温和573K下沉积时,通过脉冲激光沉积制备的AlMgB 14 N膜的硬度范围为45GPa至51GPa。 认为是由自润滑效应引起的非常低的摩擦系数0.04-0.05也已经通过AlMgB 14膜的纳米尺度试验证实。 透射电子显微镜研究表明,沉积膜是无定形的,不管基底温度如何; 然而,FTIR光谱的分析表明较高的底物温度有助于形成B 12二十面体骨架,因此导致更高的硬度。
