简介：摘要模拟器对功耗有严格要求限定，为了进一步降低模拟器平视显示系统能量损耗，必须提出新的开关控制器来降低静电MEMS驱动器的能耗。在这种情况下，本文提出了一种在非连续导通模式下(DCM)强迫电路工作的谷开关控制器，能有效减小损耗。

简介：摘要目的验证防自调输液滴数控制器在临床中的使用效果。方法将300例患者做为对照组，300例患者做为临床使用组，比较2组患者自行调节输液滴数的发生率。结果对照组的自行调节率26.33%，临床使用组竟无1例自行调节者。结论防自调输液滴数控制器操作简单、使用方便、实用性强、效果显著。

简介：摘要医用负压吸引设备系统是一般大中型医院（特别是综合性医院）的重要共用医疗设备，各临床科室都要使用，部分医技科室也需使用，特别对于手术室、ICU等科室显得特别重要，直接会影响到患者手术和救治，因此系统的稳定可靠性要求高。我们应用PLC可编程控制器对老系统进行升级改造，就是为了提高负压吸引系统的可靠性，降低设备故障发生几率，提高设备完好率。

简介：摘要随着汽车电子技术的不断发展，汽车上各种电子控制单元的数目不断增加，传统汽车电子控制单元(ElectronicControlunit)间采用点对点的通信方式，导致车内连接导线显著增加并且布线复杂，所以提高各个控制单元间通讯可靠性和降低导线成本就成为迫切需要解决的问题。为此德国BOSCH公司开发了CAN总线协议，并使其成为国际标准(ISO11898)。
