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。当一个唤醒信号识别出感兴趣的对象时，标签就会发出信号。目标是创建一个高效、稳定、低成本的室内全球定位系统。操作环境假定为计算机辅助设计格式。存在两个具有挑战性的研究问题：(1)多重反思路径；(2)作为反射次数函数的解的指数增长。将开发一种涉及素数的数学结构，以便从反射信号中有效地确定源的位置。如果成功，这项研究将导致室内全球定位系统的发展，应用于仓库、医院和图书馆，这些地方经常放错需要的物品。有了这项技术，工厂的在线调度、机场的行李跟踪、办公大楼的人员定位也可能变得可行。

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.
