Beaconing Bar Codes

9800821 Woo这个项目将研究通过主动标签在障碍物中定位没有视线的物体。在识别感兴趣对象的唤醒信号之后，标签信标。其目标是创建一个高效、坚固和低成本的室内全球定位系统。运行环境假定为计算机辅助设计格式。有两个具有挑战性的研究问题：(1)多条反射路径；(2)解的指数增长作为反射次数的函数。将开发一种涉及质数的数学结构，以便能够根据反射信号有效地确定震源位置。如果成功，这项研究将导致开发一种室内全球定位系统，应用于仓库、医院和图书馆，这些地方经常会把需要的物品放错地方。使用这种技术，工厂的在线调度、机场的行李跟踪、办公大楼中的人员定位也可能成为可能。

9800821 Woo This project will study locating objects without the line of sight amidst obstacles by means of an active tag. Upon a wake-up signal which identifies the object of interest, the tag beacons. The goal is to create an indoors global positioning system which is efficient, robust, and low-cost. The operating environment is assumed to be in a computer aided design format. There are two challenging research issues: (1) multiple paths of reflection; and (2) exponential growth of solutions as a function of the number of reflections. A mathematical structure involving prime numbers will be developed to enable efficient determination of the source location from the reflected signals. If successful, this research will lead to the development of an indoors global positioning system with applications in warehouses, hospitals, and libraries where needed items are often misplaced. On-line scheduling in factories, tracking of luggage at airports, locating personnel in office complexes may also become feasible with this technique.
