中风发生时，一切都是以秒来计算的。延误治疗可能导致大脑重大损伤。伦敦大学医学院的一位博士Alistair McEwan已经获得行为医学研究所(Action Medical Research)的同意，为急救人员开发一种无线诊断系统来减少时间延误。感谢抗血栓药物，一些病人在病情发作的三个小时之内可以完全恢复。但出血也会导致中风。医生在治疗之前需要确定发病原因，因为不适当的服用抗血栓药物会加重损害。...[详细]
随着阅读器与标签价格的降低和全球市场的扩大，射频标识 RFID(以下简称RFID)的应用与日俱增。标签既可由阅读器供电(无源标签)，也可以由标签的板上电源供电(半有源标签和有源标签)。由于亚微型无源 CMOS 标签的成本降低，库存和其他应用迅速增加。一些评估表明，随着无源标签的价格持续下降，几乎每一个售出产品的内部都将有一个 RFID 标签。由于无源 RFID 标签的重要性及其独特的工程实现...[详细]
