SBIR Phase II: Through-Building Device-free Localization for Emergency and Tactical Operations

SBIR第二阶段项目的创新之处在于为警察和特警队开发并商业化了一种低成本的穿透式建筑监控产品，该产品使用部署在建筑外部的无线传感器网络来定位和跟踪整栋建筑内的人。与其他穿透式单壁成像技术不同，设备不需要靠在墙上。该项目将开发新的技术，使该系统对警察队伍最终用户有用，无需大量培训即可快速部署和使用。具体地说，生产者应该研究在较大建筑之间实现稳健连接的方法；开发2.5维(x，y+地板)成像和跟踪能力；开发自动适应环境的自适应估计算法；开发适合快速部署的设备，并开发包括用户界面在内的实时商业原型。在项目结束时，这些发展的结合应该能够将原型交付给特种部队小组，供他们在训练演习中自行部署和使用。更广泛的/商业影响是使警察和特种部队(特种武器和战术)小组的一项技术商业化，以迅速获得拯救生命的态势情报。由于执法人员在进入大楼之前不知道大楼内发生了什么，每年都会有生命损失。此外，其他拯救生命的应用将受益于开发的技术，例如：军事城市行动；建筑安全和国土安全系统；在倒塌的建筑中或火灾救援期间寻找生还者；以及工人安全系统。这些公司的技术在系统中也很有用，这些系统通过监控老年人的活动来确保他们的安全和健康，从而允许老年人在自己的家里活得更长。针对这些挑战提出的解决方案特别有用，因为它不要求人佩戴或携带任何设备，也不能想象一个人的脸或五官，从而保护隐私。这项技术能够穿透墙壁，即使在黑暗中或烟雾中也是如此。这些功能使其在室内和室外安全系统、家庭监控系统、“智能建筑”节能系统和其他情景感知计算系统中具有吸引力。该项目开发了一种具有许多引人注目的应用的新的传感方式的技术。

The innovation of this SBIR Phase II project is the development and commercialization of a low-cost through-building surveillance product for police and SWAT teams that locates and tracks people across an entire building using a network of wireless sensors deployed around the outside of the building. Unlike other through-single-wall imaging technologies, a device does not need to be held against a wall. This project will develop new technologies that make the system useful for police team end-users to quickly deploy and use without extensive training. Specifically, the produce should investigate methods to achieve robust connectivity across larger buildings; develop capabilities for 2.5-dimensional (x,y + floor) imaging and tracking; develop adaptive estimation algorithms that automatically adjust to the environment; develop devices suited for rapid deployment, and develop a real-time commercial prototype including user interface. At the end of the project, the combination of these developments should allow delivery of a prototype to a SWAT team for them to deploy and use on their own in a training exercise.The broader/commercial impact is the commercialization of a technology for police and SWAT (special weapons and tactics) teams to quickly obtain situational intelligence that will save lives. Lives are lost every year because law enforcement officers do not know what is happening inside a building prior to entering. In addition, other life-saving applications will benefit from technologies developed, for example: military urban operations; building security and homeland security systems; finding people alive in collapsed buildings or during fire rescue; and worker safety systems. The firms technology is also useful in systems that allow elderly to live longer in their own home by monitoring their activities to ensure their safety and health. The proposed solution to these challenges is uniquely useful because it does not require a person to wear or carry any device, and cannot image a person's face or features, thus preserving privacy. The technology is capable of "seeing" through walls, even in the dark or through smoke. These features make it compelling for indoor and outdoor security systems, in-home monitoring systems, "smart building" energy-conservation systems, and other context-aware computing systems. This project develops technologies for a new sensing modality with many compelling applications.
