This project will develop and test an Ambulatory Wireless Sleep Monitoring (AWSM) System. This the AWSM system measures and transmits physiological signals for sleep monitoring and diagnostics of sleep abnormalities. This will allow at-home sleep monitoring without having the subject tethered with wires and also enables the patients to be monitored in any hospital bed. outside the specialized hospital sleep monitoring units. AWSM will be capable of recording up to 12 hours of bio-electric signals such as EEG, EOG, ECG, and EMO as well as respiratory related signals such as nasal airflow (thermistry) and chest-wall respiratory effort measurement (Piezo) on ambulatory patients in their home environment. The proposed system takes advantage of the telemetry technology that has already been developed at Cleveland Medical Devices Inc. under prior NIH Phase I and Phase II SBIR grants. All the electrodes and respiratory channels are connected to a small light-weight flexible case which transmits the data by 1 mW FM signals. This minimizes interference with the patient's normal sleep. This wireless feature has several advantages compared to the existing portable systems including: * Minimizing accidental detachment of the electrodes during sleep at the home environment. * Providing a higher reliability home sleep monitor which will reduce the cost for sleep studies by 75% and provide more natural sleep, eliminating "first-night effects" and the psychological effects of being in the hospital. * Comfortable sleeping condition, which is extremely important for the elderly patients and children, allowing patients to easily leave their beds and move around the house. * Practical system for infants monitoring. The wireless feature is very important in studying the infants because they tend to grab and pull the wires. PROPOSED COMMERCIAL APPLICATION: In addition to being used to monitor sleep, the AWSM system can be used to communicate the vital signs on patients iii the hospital or at home without interfering with similar systems of other patients. The same unit has numerous industrial and commercial applications for real time control and monitoring. The AWSM system can also be used for markets as diverse as conducting special studies in the workplace to controlling virtual reality games with brainwaves.

该项目将开发和测试一个动态无线睡眠监测 （AWSM）系统。该AWSM系统测量并传输生理 用于睡眠监测和睡眠异常诊断的信号。这 将允许在家中进行睡眠监测， 还能让病人在任何医院都能被监控 睡觉了在医院的睡眠监测中心之外 AWSM将能够记录长达12小时的生物电信号 例如EEG、EOG、ECG和EMO以及呼吸相关信号， 作为鼻气流（呼吸）和胸壁呼吸努力测量 （压电）在他们的家庭环境中的门诊病人。拟议 该系统利用了遥测技术， 由Cleveland Medical Devices Inc.开发。在之前的NIH I期和 第二阶段SBIR赠款。所有的电极和呼吸通道 连接到一个小的重量轻，灵活的情况下，传输数据， 1 mW FM信号。这最大限度地减少了对患者正常 睡吧这种无线功能与 现有的便携式系统包括： * 最大限度地减少睡眠期间电极的意外脱落， 家庭环境。 * 提供更高可靠性的家庭睡眠监测器， 睡眠研究的成本降低了75%，并提供更自然的睡眠，消除 “初夜效应”和处于 医院 * 舒适的睡眠条件，这是非常重要的， 老年患者和儿童，使患者能够轻松离开病床 在房子里走动 * 实用的婴儿监护系统。无线功能非常 这在研究婴儿时很重要，因为他们倾向于抓住并拉住婴儿。 电线. 建议的商业应用：除了用于监测 睡眠时，AWSM系统可用于传达生命体征， 患者在医院或家中，而不干扰类似的 其他患者的系统。 同一单位有许多工业和 用于真实的时间控制和监视的商业应用。AWSM 系统还可以用于各种市场， 在工作场所的研究，以控制虚拟现实游戏， 脑电波
