Statistics Canada reports that approximately one in three Canadian seniors encounter a fall annually, with 65% of them at night times. Fall risk is significantly higher for dementia patients with higher sleep disturbances and seniors need significantly high levels of illumination for postural orientation. In this project, the team will been developing a way-finding and fall prevention lighting system for seniors, particularly those with Alzheimer's disease and related Dementias (ADRD). These fall prevention lights should operate automatically with no user controls, as it will be very difficult for dementia patients to learn anything new. Wireless sensors such as motion, bed-occupancy, and door contact will be integrated to the system. The proposed integrated controller will unify various wireless connectivity protocols - ZigBee (for bed occupancy), RF 433 MHz (for motion and contact sensors), Bluetooth (for future integration to smoke and CO detectors and front door lock), and Wi-Fi (for Smart Home integration). Seniors also may need varying degree of brightness for these lights, depending on their vision defects, such as cataracts, macular degeneration. The lights have to operate at various dimming levels for fade-in and fade-outs. Dimming of LED lights may result in temporal modulation of the lights which is highly undesirable. The controller should thus be able accommodate a variety of power driver requirements to eliminate flicker. This project will help Lumentra launch a unique product in safety lighting for seniors. Canada spends $2 billions/year for providing health care for seniors who experience falls. Our fall-prevention lights will help substantially reduce this incremental health care expense.

加拿大统计局报告说，大约三分之一的加拿大前辈每年遇到一个秋天，夜间有65％。患有较高睡眠障碍的痴呆症患者的跌倒风险明显更高，而老年人则需要明显高水平的照明才能姿势取向。在这个项目中，该团队将为老年人，尤其是患有阿尔茨海默氏病和相关痴呆症（ADRD）的老年人开发一种方向检测和跌落的预防照明系统。这些秋季预防灯应在没有用户控件的情况下自动运行，因为痴呆症患者很难学习任何新的东西。无线传感器（例如运动，床上占用和门接触）将集成到系统中。拟议的集成控制器将统一各种无线连接协议-Zigbee（用于床占用），RF 433 MHz（用于运动和接触传感器），蓝牙（用于将来集成到烟雾和CO探测器和前门锁），以及Wi -Fi（Wi -Fi（用于智能家庭集成）。这些灯的老年人也可能需要不同程度的亮度，具体取决于他们的视力缺陷，例如白内障，黄斑变性。灯光必须在各种调度水平上运行，以使其淡入淡出和淡出。 LED灯的变暗可能会导致高度不受欢迎的灯光的时间调节。因此，控制器应该能够满足各种电动驱动器的要求，以消除闪烁。该项目将帮助Lumentra推出针对老年人安全照明的独特产品。加拿大每年为经历跌倒的老年人提供医疗保健费用。我们的秋季预防灯将有助于大大减少这笔增量的医疗保健费用。
