(Warning)The protector functions only improve the IC’s tolerance and they do not guarantee the safety of the IC if used under the conditions out of
safety range or ratings. Use of the IC such as use under overcurrent protection range or thermal shut down state may degrade the IC’s reliability and
eventually damage the IC.

performed with pulse load to minimize the increase of junction temperature(Tj).
2008年7月9日, CombOLED 研究项目的工作重点是开发出高性价比的生产工艺，以实现有机发光二极管 (OLED) 的量产。欧司朗光电半导体公司固态照明部主管 Bernhard Stapp 表示：“该项目由欧盟提供资金支持，欧司朗负责协调运作，旨在为推行新型照明光源应用创造必要的条件。”这包括采用性价比卓越的方法构建新型元件架构，从而生产出大幅面透明光源。作为 LED 市场的创新推...[详细]
UHF和HF都是一般的技术分类，不过每一类都有独立的支持协议。HF在13.56MHz频段更具有一致性，虽然国际业内行业标准很多。UHF RFID在858-960MHz频段已商业化。同时也有多种国际标准支持，包括EPC global Gen 2。 标签与读写器通过无线链接交换数据。链接可以通过适合任何频段的、具有不同读取范围和抗干扰性的EMF或RF场实现。HF RFID技术主要通过电磁场传送信...[详细]

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]
