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.

在老龄化人口中，老年人的跌倒被认为是一个主要的健康问题。 由于缺乏传感器和无线通信系统，无法很好地理解体育活动模式，导致下降的情况以及识别身体运动模式不可避免地导致跌倒的方法的方法。 可以在体内佩戴的传感器，同时可以访问本地数据传输和国家通信网络，并允许以准确，方便，不引人注目和社会上可接受的方式不断监视患者。 在这项研究中，Sarcos将：1）设计，原型和测试用于记录和无线传输加速度和身体位置数据的研究系统。2）开发特征提取和初步解释性算法，以表征秋季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视系统连接到国家通信网络有关的问题，以使未来的安全网络为社区生活的老年人提供。 Sarcos员工在DARPA赞助的人员状态监测项目中既有经验和技术，该项目可以解决与老年人的卧床监测有关的关键传感器和沟通问题。拟议的商业应用：本研究的潜在商业应用包括一系列产品，例如Pager大小的监视器，通过蜂窝要求网络运行，用于疗养院的监测站和服务以及用于研究老年人群体育活动模式的研究设备。 仅根据65岁及以上的潜在用户数量，以270万美元的价格估算了该市场的Pager-Monitor细分市场，并且随着这组人口的增加而增长。
