Background: Today, living standards and medical tech.ology are improving, and the aging global population is increasing. However, more and more older adults are suffering from knee diseases. This will seriously affect patients’ daily life and their mental state. In many studies, repeti-tive physical exercises and motor activities in real-world environments have been shown to help im-prove knee muscle strength and restore damaged nerves. Therefore, physical knee therapy is very nec-essary. The use of rehabilitation training devices for movement therapy has shown great potential. Objective: This study aimed at exploring the structural features, functions, and development status of the knee rehabilitation training device. Methods: This review explores the structure and function of various current knee rehabilitation devices based on structural and kinematic properties of the knee joint in relation to requirements of physical knee rehabilitation. This paper aims to present a systematic guideline and outline a refer-ence for future designers of rehabilitation devices. Results: By analyzing the structure and movement of the knee joint and combining the strategies of physical knee rehabilitation, movement requirements during knee rehabilitation training are con-cluded. According to the structure, drive form, transmission mode, and rehabilitation environment of knee rehabilitation devices, the devices are classified and compared;some typical features are summarized;some current problems are analyzed, and the future trends and development directions of rehabilitation devices are discussed. Conclusion: Current rehabilitation equipment has a variety of structures and functions, but a good balance between weight and volume is hardly maintained. The protection of the body needs to be further improved. Many knee rehabilitation devices are only concepts, not physical objects, and lack clinical trial data. Power sources and drives are large and heavy, which can compress the knee jo

Recent Patents on Mechanical engineering 2022年第2期15卷 106-121页

作者： Jiang, Jingang Gao, Ziwen Wu, Dianhao Yu, Xiaoyang Guo, Yafeng Key Laboratory of Advanced Manufacturing and Intelligent Technology Ministry of Education Harbin University of Science and Technology Harbin150080 China Intelligent Machine Institute Harbin University of Science and Technology Harbin150080 China School of Measurement-Control Tech and Communications Engineering Harbin University of Science and Technology Harbin150080 China

Background: After a smooth development of life expectancy per capita and fertility in the nineteenth century, the global population increased in size. Along with the demographic shift in the late nineteenth century, the phenomenon of population aging began to appear in developed countries. A survey from UN reports that by 2050, one in six people worldwide will be over 65 years old (16%), compared to 11 (9%) in 2019. According to another survey, 55% of people over the age of 60 suffer from joint diseases, and the number of people suffering from stroke, arthritis and other knee diseases will also increase accordingly. Objective: An overview of the classification and characteristics of today's knee rehabilitation devices and future developments. Methods: This review discusses the existing knee rehabilitation devices, including various prod-ucts on the market, patents and some conceptual devices, in the context of the structural characteristics of the knee joint and the rehabilitation requirements of different knee conditions or after knee arthroplasty, and systematically introduces their structural features, differences and the rehabilitation effects achieved. Results: A comparative analysis of three types of passive knee rehabilitation devices according to their use was conducted to summarize the typical characteristics. The problems that exist in today's rehabilitation devices are also analyzed, and their development trends are looked forward to. Conclusion: Knee rehabilitation equipment has a high degree of structural richness, but it does not achieve a good balance of convenience, comfort and functionality, and there should be some room for improvement in the materials, volume of the power source and transmission form of the power system. There will be a good development in the future of knee joint recovery. © 2022 Bentham Science Publishers.

ISBN: (纸本)9788895608655

In the petrochemical and coal chemical industries, in order to avoid production accidents caused by harmful gas leakage, this paper uses a kind of AlN-based semiconductor MEMS four-array sensor to identify the four kinds of harmful gases of Cl2, CO, NO2 and SO2. Through wireless sensor network, it uses the iterative smoothing l0 norm minimization algorithm to compress and reconstruct the odor identification data, and finally realizes the odor identification and data transmission in the chemical environment. The experimental results show that the method used in this paper reconstructs the odor identification data with less observations. While reducing the data collection cost of the wireless sensor network, it can effectively identify and detect harmful gases to achieve the purpose of risk warning. © 2018, AIDIC Servizi S.r.l.
