This proposal is aimed to support a collaborative research initiative between the applicants at the University of Waterloo and Lockheed Martin Canada (LMC). The main goal of this work is to develop a prototype external active compression device with military and medical applications. For the military, the device aims to reduce fatigue and improve recovery time of active soldiers, while medical applications include treatment and prevention of venous insufficiency disorders. The latter is a concern for military personnel subjected to long bouts of immobility, such as drone pilots. The proposed compression system is based upon a novel "smart" compression protocol developed by the applicants that shows considerable physiological benefits to the blood circulation in the legs upon application; increased blood flow in the extremities dramatically reduces the risk of venous disorders while also flushing out waste products to reduce fatigue and improve recovery time from exercise. For both the military and medical applications, the primary remaining research challenge is the development of a working prototype for ambulatory users. The current laboratory system consists of pneumatic compression cuffs and a series of laboratory-grade wired physiological instruments, which tethers the user to the wall. Transitioning to a wireless, ambulatory prototype requires: exploration and characterization of wireless biometric sensors (data rate, signal-to-noise, etc.), design of an in situ pressure measurement system for monitoring compression levels in real time, development of a robust closed-loop compression control strategy using the new biometric sensing platform, and development and validation of novel actuation strategies for applying the external compression. During the course of the proposed work, a LMC backed start-up company will be founded in Canada to commercialize the developed product. This company will serve as a technology supplier to LMC for the military market, while also advancing a product to the medical market.

该建议旨在支持滑铁卢大学和加拿大洛克希德·马丁（LMC）的申请人之间的合作研究计划。这项工作的主要目标是开发具有军事和医疗应用的原型外部主动压缩装置。对于军队而言，该设备旨在减少疲劳并改善活跃士兵的恢复时间，而医疗应用包括治疗和预防静脉疾病不足。后者是军事人员的关注点，遭受了长期不可动作的行为，例如无人机飞行员。拟议的压缩系统基于申请人开发的一种新颖的“智能”压缩方案，该协议在施用后对腿部的血液循环显示出很大的生理益处。四肢的血流大大降低了静脉疾病的风险，同时还会冲洗废物以减轻疲劳并改善运动中的恢复时间。对于军事和医疗应用，主要剩余的研究挑战是开发为门诊用户的工作原型。当前的实验室系统由气动压缩袖口和一系列实验室有线生理仪器组成，它们将用户置于墙壁上。过渡到无线的卧床原型需要：无线生物特征传感器的探索和表征（数据速率，信号到信号等），用于实时监控压缩水平的原位压力测量系统的设计，使用新的生物识别传感平台和外部验证的新型生物识别策略来实现强大的闭环压缩控制策略的强大压缩策略。在拟议的工作过程中，将在加拿大成立一家LMC支持的初创公司，以商业化开发产品。该公司将在军事市场上担任LMC的技术供应商，同时还将产品推向医疗市场。
