DESCRIPTION (provided by applicant): Falls and fall-related injuries in seniors are more common than strokes and can have equally serious consequences; they represent a signicant health care problem with a substantial associated morbidity and reduction in overall mobility and function. Thirty percent of adults 65 years and older fall each year, often suering dangerous closed head injury and long bone fractures. Fall-related injuries are the number one reason for emergency room visits and the leading cause of injury-related deaths among elderly adults. Studies have shown that half of elderly fallers cannot get up without assistance after they have fallen, often lying in anxiety and/or pain for far too long until discovered. The majority of eldes prefer to lead an independent lifestyle, with a minimum of caregiver intervention. Many seniors, however, are frail and suer from imbalance as a result of their health status; they are at risk for falls and would benet from having a safety net in place. Barron Associates proposes to develop the EverWrist fall monitoring system. The EverWrist will employ a novel, patent-protected paradigm to detect falls, and will automatically summon assistance by sending a wireless signal to a console unit that delivers an alert to a prioritized list of caregivers, ensuring that it is received by a human being. A button on the EverWrist monitor will also enable wearers to initiate personal emergency alert calls and to cancel an alert call in progress if assistance is no needed. Additionally, the EverWrist monitor will be able to detect and log near-fall events, which are of particular interest to health care personnel to identify individuals in need of further intervention to avoid future falls. The majority of previously available commercial fall detectors were waist-mounted; as such, they were not true all-day monitors, since they could not be worn comfortably during sleep and had to be removed to bathe or change clothes. The relatively large size of these fall monitors caused them to be conspicuous, resulting in very low adoption rates. Additionally, the fall detection algorithms used in nearly all previously-available devices were simplistic, leading to an unacceptably high rate of false alarms and/or missed detections. To overcome the problems of earlier devices, a patent-pending sensing technique will be utilized in the EverWrist system that greatly improves accuracy and reliability in detecting falls. The new approach will be productized in the form of a commonly worn and socially acceptable accessory, making it discreet and unobtrusive to wear. A novel algorithmic methodology, motivated and supported by recent research, will be incorporated into the monitor to detect near-fall events and discriminate these events from actual falls and other activities of daily livig. The approach challenges existing paradigms for fall and near-fall event detection. The resulting EverWrist system will be well positioned in terms of market demand (i.e., need for an ergonomic monitor that can be worn 24/7).

描述（由申请人提供）：老年人中的福尔斯和跌倒相关损伤比中风更常见，并且可能具有同样严重的后果;它们代表了一个显著的卫生保健问题，具有显著的相关发病率和整体活动性和功能降低。每年有30%的65岁及以上的成年人摔倒，经常造成危险的闭合性头部损伤和长骨骨折。跌倒相关的伤害是急诊室就诊的首要原因，也是老年人与伤害相关的死亡的主要原因。研究表明，有一半的老年跌倒者在跌倒后无法在没有帮助的情况下站起来，通常在焦虑和/或疼痛中躺了很长时间，直到被发现。 大部分长者都喜欢独立生活，很少有照顾者介入。然而，许多老年人由于健康状况不平衡而身体虚弱，他们有患上糖尿病的危险。 福尔斯和将benet从有一个安全网到位。 巴伦联合公司建议开发EverWrist跌倒监测系统。EverWrist将采用一种新颖的、受专利保护的模式来检测福尔斯，并将通过向控制台单元发送无线信号来自动召唤援助，该控制台单元将警报发送给护理人员的优先列表，确保它被人类接收。EverWrist监视器上的一个按钮也将使佩戴者能够启动个人紧急警报呼叫，并在不需要帮助的情况下取消正在进行的警报呼叫。此外，EverWrist监护仪将能够检测和记录接近跌倒事件，这对医疗保健人员特别感兴趣，以识别需要进一步干预的个人，以避免未来的福尔斯。 大多数以前可用的商业跌倒探测器 腰挂式;因此，它们不是真正的全天监测器，因为它们在睡眠时不能舒适地佩戴，并且必须在洗澡或换衣服时取下。这些跌倒监测器相对较大的尺寸导致它们很显眼，导致采用率很低。此外，在几乎所有先前可用的设备中使用的跌倒检测算法都过于简单，导致不可接受的高误报警率和/或误检测率。 为了克服早期设备的问题，EverWrist系统将利用一种正在申请专利的传感技术，大大提高检测福尔斯的准确性和可靠性。这种新的方法将以一种普遍佩戴和社会可接受的配件的形式产品化，使其佩戴起来谨慎而不显眼。由最近的研究激发和支持的一种新的算法方法将被纳入监测器中，以检测接近跌倒的事件，并将这些事件与实际的福尔斯和其他日常生活活动区分开来。该方法挑战了现有的跌倒和接近跌倒事件检测的范例。由此产生的EverWrist系统将在市场需求方面处于有利地位（即，需要一个符合人体工程学的监视器，可以佩戴24/7）。
