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]
便携式医疗设备的特殊性决定了它们应该是对用户友好的、必须工作在无菌环境下,并且空间占用小、耗能低。 同时,便携式医疗设备还需要足够的计算能力以便处理医疗数据,能够连接到无线或有线接口以便记录和发送数据。从设计人员的角度考虑,上述需求需要低功耗的单片机(MCU)和数字信号控制器(Digital Signal Controller,DSC)。 正是有了嵌入式处理器,设计人员才有可能设...[详细]
