As the global elderly population continues to grow and the elderly home care needs grow correspondingly, having family members take care of or hire 24-hour nursing care at any time will inevitably affect the employment of other members of the family and increase their costs. Nowadays, through the development of the Internet of Things technology, Elderly people's position and movement at home Internet of Things monitoring technology real-time tracking of indoor activity of the elderly As the global elderly population continues to grow and the elderly home care needs grow correspondingly, it is bound to affect the workforce and school attendance of other members of the family and increase the huge care cost expenditure by requiring them to take care of or take part in 24-hour care. The IoT ) Technology has developed indoor positioning system (IPS) technology to keep track of the location and mobility of elderly people in their homes at any time to help families or support agencies save the cost of huge human-care and to provide higher quality seniors Care solution. According to the Iot Solution Provider website, the global surging population of the elderly continues to surge, with the so-called "Silver Tsunami," according to a survey conducted by the National Center for Health Statistics at the Centers for Disease Control and Prevention (CDC) The 1.4 million elderly population live in support institutions and it is estimated that by 2030 this number will be close to the doubling scale. Experts also expect that by 2030, the average life expectancy of mankind will grow to 110 years. This shows that the global elderly population will continue to increase in the future. Under such circumstances, the elderly care and maintenance needs of home care care providers are bound to escalate simultaneously. It is bound to form a major expenditure and care burden on families. The supporting agencies must also employ more manpower to monitor the elderly at any time to prevent accidents such as falls occur. However, with the advent of IoT technology, it is now possible to detect precisely the indoor location and movement of seniors using IPS technology in combination with mobile devices and beacons installed on the wall or ceiling of an interior, Living habits and other information to move the path prediction, help to grasp the situation of indoor activities of the elderly without human care at any time, allowing the elderly to live longer independently at home, or reduce the human resources expenditures in the maintenance center. In addition, cloud-based applications based on machine-to-machine (M2M) technology can also be provided through a combination with Intel's Intelligent Systems Framework to provide the necessary networking requirements for geriatric safety monitoring and Can avoid the leakage of private investment. Such IPS and smart home gateway solutions, such as the ultrasound-based indoor positioning technology commonly deployed in hospitals to track and locate the patient's location, can be used to assist indoor seniors in tracking applications with nearly 100% accuracy at Automatically track the elderly in a complex indoor environment. This type of device is easy to install, usually battery-powered and affordable, as long as there is a wide area communication interface and emergency call zone settings available. This type of ultrasound technology is continuously monitored by the Smart Home Care Gateway. Ultrasound indoor location signals are highly accurate and provide 3D data with an accuracy of only 3 cm. Once an accident is detected in any seniors, the built-in wireless The WAN will automatically and quickly send alert signals to inform relatives, home care providers or secure call centers for immediate assistance through the M2M platform. In addition, there is no need to install the technology can be applied indoors, such devices built a small waterproof sensor, for example, wearable devices worn by the elderly on the wrist, the device will be fixed every 15 to 20 seconds will be delivered with Wearer positioning signal to the ultrasonic receiver, and then through the standard wireless WLAN and home care gateway link, you can provide real-time indoor tracking service. These wearable positioning devices do not require any physical network link requirements, are easy to use and maintain, are battery powered, and have a useful life of up to three years. There is no charging port for such devices for charging and a new battery can be replaced every 2-3 years , Will help provide more convenient and long-term positioning tracking service. Robot has been used widely in modern industry. With the deeply urge for automation in polishing field, robot has been a smart mehtod to realize grinding automation. Our active contact flange connects with robot, can work in grinding polishing sanding, high working efficiency, low cost and cleaning working environment. More and more manufacturers choose this method to realize automation reform. So this method has been used in metal,plastics,acrylic, wood, compound material processing in 3c, household sanitary ware, auto parts, transportation tools etc. polishing use robot,robot use in polishing,robotic polishing machine DARU Technology (Suzhou) Co., Ltd. , https://www.szdaruactivecontactflange.com
