Falls in elderly have been recognized as a major health problem in an aging population. Physical activity patterns, circumstances leading to falls, and methods for recognizing body motion patterns inevitably resulting in falls are not well understood due to lack of sensors and wireless communication systems for continuous recording of data required for such analysis. Sensors that can be worn on the body, with access to both local data transmission and national communication networks, and which allow continuous monitoring of patients in accurate, convenient, unobtrusive and socially acceptable manner, need to developed. In this study, Sarcos will: 1) Design, prototype and test a research system for recording and wirelessly transmitting acceleration and body position data from ambulatory persons.2) Develop feature extraction and preliminary interpretive algorithms for characterizing accelerations and body positions during fall events. 3) Analyze issues related to connecting the proposed sensor and monitoring system into a national communication network to enable future development of a practical safety network for community living elderly persons. Sarcos staff has both the experience and technology developed during the DARPA sponsored Personnel Status Monitor project that enable to solve critical sensor and communication issues related to ambulatory monitoring of the elderly. PROPOSED COMMERCIAL APPLICATIONS: Potential commercial applications of this research include a range of Products such as pager-size monitors, operating via cellular paging networks, monitoring stations and services for nursing homes and research devices for studies of physical activity patterns in elderly population. Only the pager-monitor segment of this market is estimated, based on the number of potential users aged 65 yrs and older, at 270 mln dollars, and will grow as this group of population increases.

老年人跌倒已被认为是人口老龄化中的一个主要健康问题。 由于缺乏用于连续记录这种分析所需的数据的传感器和无线通信系统，人们对身体活动模式、导致跌倒的环境以及识别不可避免地导致跌倒的身体运动模式的方法还没有很好地了解。 需要开发可以佩戴在身体上、可以访问本地数据传输和国家通信网络的传感器，并且可以以准确、方便、不引人注目和社会可接受的方式持续监测患者。 在这项研究中，Sarcos 将：1) 设计、原型设计并测试一个研究系统，用于记录和无线传输步行者的加速度和身体位置数据。2) 开发特征提取和初步解释算法，用于表征跌倒事件期间的加速度和身体位置。 3) 分析与将拟议的传感器和监控系统连接到国家通信网络相关的问题，以便未来为社区老年人开发实用的安全网络。 Sarcos 工作人员拥有 DARPA 赞助的人员状态监测项目期间开发的经验和技术，能够解决与老年人动态监测相关的关键传感器和通信问题。拟议的商业应用：这项研究的潜在商业应用包括一系列产品，例如通过蜂窝寻呼网络操作的寻呼机大小的监视器、疗养院的监测站和服务以及用于研究老年人身体活动模式的研究设备。 根据 65 岁及以上的潜在用户数量，仅寻呼机显示器部分的市场规模预计为 2.7 亿美元，并将随着该群体人口的增加而增长。
