美国发布公共安全网络技术路线图
美国 公共安全 网络
2015/5/29
美国商务部国家标准与技术研究院（NIST）近日公布了全美未来20年发展无缝宽带公共安全通信网络技术的路线图，其规划的系列技术主要集中于为警察、消防员、紧急医疗服务和其他急救等提供基于定位所需的各类服务。路线图由NIST的公共安全通信研究（PSCR）项目组完成，该机构从2002年开始就执行标准的研究、开发、测试和评价。NIST新通信技术实验室PSCR部门负责人德雷克·奥尔说：“路线图将指导和规划公共...
自2001年以来，美国的《MIT技术评论》每年都评选出十大技术榜单，关注最有可能改变世界的创新性技术。去年的评选结果包括农业无人机、脑图技术、基因编辑技术、神经形态芯片、微型3D打印技术等。
美国实现远距离电网模拟实时互动
美国 电网 数据
2015/5/18
近日，美国国家可再生能源实验室（NREL）以及爱达荷国家实验室（INL），成功展示了通过互联网进行电网模拟实时互动能力。
NREL网报道称，两个实验室能够连接其“实时数据模拟器”（RTDS）达到电网模拟效果，其中一个实验室的硬件或软件能直接与另一个的互动。连接时，本地电网能够掌控任何流入和流出硬件的真实电流。INL的多个实时数据模拟器机架与NREL的网格模拟器连接，则能同时模拟含有多个电动汽车和...

俄罗斯科学家研制成功新型“穿墙透视器”
俄罗斯科学家 穿墙透视器
2014/11/3
据《俄罗斯日报》近期消息，俄罗斯试验开发设计局的研究人员研制成功一种能穿透障碍物，搜寻目标的仪器。该仪器工作原理类似于雷达，通过发射波并回收由目标物体反射回来的波而搜寻目标。其区别于其它类似仪器的主要优点在于：一是其它仪器发射波的波段一般较窄，造成穿透能力弱，搜寻效果不佳，而该新型仪器发射波段位于1-3.5吉赫，搜寻效果较佳；二是这种新型仪器通过发射只有550皮秒的短脉冲，极大地提高了搜寻移动目标...
