Abstract: The recent pandemic has shown its different shades across various solicitations, especially in the healthcare sector. It has a great impact on transforming the traditional healthcare architecture, which is based on the physical approaching model, into the modern or remote healthcare system. The remote healthcare approach is quite achievable now by utilizing multiple modern technological paradigms like AI, Cloud Computing, Feature Learning, the Internet of Things, etc. Accordingly, the pharmaceutical section is the most fascinating province to be inspected by medical experts in restoring the evolutionary healthcare approaches. Covid 19 has created chaos in the society for which many unexpected deaths occur due to delays in medication and the improper prognosis at an irreverent plan. As medical management applications have become ubiquitous in nature and technology-oriented, patient monitoring systems are getting more popular among medical actors. The Internet of Things (IoT) has achieved the solution criteria for providing such a huge service across the globe at any time and in any place. A quite feasible and approachable framework has evolved through this work regarding hardware development and predictive analysis. The desired model illustrates various approaches to the development of a wearable sensor medium that will be directly attached to the body of the patients. These sensor mediums are mostly accountable for observing body parameters like blood pressure, heart rate, temperature, etc., and transmit these data to the cloud storage via various intermediate steps. The storage medium in the cloud will be storing the sensor-acquired data in a time-to-time manner for a detailed analysis. Further, the stored data will be normalized and processed across various predictive models. The model with the best accuracy will be treated as the resultant model among the numerous predictive models deployed in the cloud. During the hardware development process, several hardware modules are discussed. After receiving sensor-acquired data, it will be processed by the cloud's multiple machine-learning models. Finally, thorough analytics will be developed based on a meticulous examination of the patients' cardinal, essential, and fundamental data and communicated to the appropriate physicians for action. This model will then be used for the data dissemination procedure, in which an alarm message will be issued to the appropriate authorities.

Background: Since the first industrial robots were created in the middle of the last century, robotics has shown strong growth prospects. Robotics has developed rapidly over time and is being used in more and more areas. Because of the need to minimize impact forces during robot movement, traditional rigid robots are no longer sufficient, flexible joints are more adaptable to the environment due to their adjustable stiffness and have higher application value in humancomputer interaction. Therefore, flexible jointed robots have become one of the research hotspots in recent years. Objective: Through a detailed analysis of the existing hardware and software control technologies of flexible joint robots, referring to papers and recent patents on flexible jointed robots, we aim to find ways to reduce the impact of flexible joint deformation of flexible joint robots and improve the overall force and position control accuracy of flexible joint robots. Methods: To categorize the hardware and software technologies of flexible jointed robots, to briefly explain the directions of the technologies categorized and to study them, to summarize the advantages and disadvantages of each type of technology respectively, and to outlook the future development trend. Results: Through the study and analysis of the various parts of the flexible joint robot, it can be seen that joint flexibility is mainly achieved through the drive motor and flexible components to achieve flexibility and then through the fusion control technology to control the deformation of the joint. Differences in structural materials affect the mechanical properties of robot motion. The detection and feedback accuracy of the sensor also has a significant impact on the control accuracy. Conclusion: The use of new motor technology, flexible component technology, material technology, and sensor technology, combined with improvements in software fusion control technology can reduce the impact of joint deformation, improve the control accuracy of joint flexibility, and achieve high-precision force-level control capability of flexible joint robots.

Objective: The objective of this study is to analyze the performance difference between simplified and digital models based on medical images. Methods: According to the characteristics of human anatomy, the finite element simulation software COMSOL Multiphysics 5.5 was employed to construct a simplified arm model using cylinders and a digital arm model based on Chinese digital human regarding electroacupuncture therapy as an example. A comparative analysis was then performed considering three aspects: mesh number, potential distribution, and resource consumption. Results: Through analysis, the digital arm model based on Chinese digital human requires significantly more mesh cells than the simplified arm model in mesh generation. Meanwhile, because the digital arm model based on the Chinese digital human fully expresses the nonuniformity of the tissue distribution in a real human body, its signal distribution in its interior is also relatively scattered, and the coupling potential slightly differs at the electrode vertex with the smallest change. In addition, the digital arm model has much higher resource consumption and computer hardware resource requirements compared with the simplified arm model. Conclusion: As a result, the digital model based on the Chinese digital human can more fully express the tissue distribution and electrical signal characteristics of a real human body. However, due to its high computational requirements, appropriate simplification can be selected to improve the computational efficiency of the model in practical applications.

Abstract: The scientific community is currently very concerned about information and communication technology security because any assault or network anomaly can have a remarkable collision on a number of areas, including national security, the storage of private data, social welfare, economic concerns, and more. As a result, many strategies and approaches for this goal have been developed over time, making the anomaly detection domain a large research subject. The primary concern of this study is to review the most crucial elements relating to anomaly detection, including an overview of background analysis and a core study on the most important approaches, procedures, and systems in the field. To make the structure of this survey easier to understand, the domain of anomaly detection was examined along with five dimensions: Detection methods in network traffic, objectives of the paper, various datasets used, accuracy, and open issues/ gaps. The gap which has been identified after the survey can be extended as a future scope might be helpful for the researcher.

Background: With the advent and rapid development of 5G technology, many electronic products have been developed in the miniaturized direction. However, excessive operating temperature generated by these electronic products in a small space results in serious runaway problems, such as battery failure and dead equipment. To solve the heat dissipation problem of small electronic products, ultra-thin vapour chambers are widely used in the heat dissipation field of these electronic products due to the characteristic of rapid heat conduction and thermal expansion. Therefore, optimizing the performance of ultra-thin vapour chambers is critical. Over the years, optimizing the performance of ultra-thin vapour chambers has piqued the industry's interest. Objective: This study aimed at exploring the structural features, optimization method, and development status of the ultra-thin vapour chambers. Methods: This study reviews various representative patents related to ultra-thin vapour chambers and discusses the problems existing in the process of achieving ultra-thinning to provide a reference for designers of ultra-thin vapour chambers in the future. Results: Through the investigation of a large number of patents on ultra-thin vapour chamber, some existing problems are summarized and analyzed. Finally, the future trend of ultra-thin vapour chambers is discussed. Conclusion: The optimization of ultra-thin vapour chambers benefits the heat dissipation of small electronic products and improves product safety. More related patents will be published in the future.

Therefore, optimizing the performance of ultra-thin vapour chambers is critical. Over the years, optimizing the performance of ultra-thin vapour chambers has piqued the industry's interest. Objective: This study aimed at exploring the structural features, optimization method, and development status of the ultra-thin vapour chambers. Methods: This study reviews various representative patents related to ultra-thin vapour chambers and discusses the problems existing in the process of achieving ultra-thinning to provide a reference for designers of ultra-thin vapour chambers in the future. Results: Through the investigation of a large number of patents on ultra-thin vapour chamber, some existing problems are summarized and analyzed. Finally, the future trend of ultra-thin vapour chambers is discussed. Conclusion: The optimization of ultra-thin vapour chambers benefits the heat dissipation of small electronic products and improves product safety. More related patents will be published in the future.","PeriodicalId":40022,"journal":{"name":"Recent Patents on Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134945071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background:: Most of the patients with limb paralysis caused by stroke and traumatic brain injury are unable to take care of themselves, which not only causes great physical and psychological stress to the patients but also poses a heavy burden on their families and society. The global population is entering the aging phase. The number and proportion of older people is increasing in almost every country in the world. Population aging has the potential to become one of the most important social trends of the 21st century, and almost all areas of society are affected by it, including labor and financial markets, demand for goods and services, such as housing, transportation, and social security, family structures, and intergenerational relationships. Rehabilitation robotics is a research field that has emerged from this demand. Objective:: Through the analysis of the current situation and development of upper limb rehabilitation robots, several types of upper limb rehabilitation robots with the most widely used structures today are extracted from the representative results, and each robot is analyzed and elaborated in detail. It provides a reference for readers to choose the appropriate upper limb rehabilitation robots. Methods:: We have classified the upper limb rehabilitation robots through several patents, briefly explained and analyzed the robots grouped, summarized the advantages and disadvantages of various robots, and provided an outlook on future development trends. Results:: Through the research and analysis of the degree of freedom and control system of the upper limb rehabilitation robot, it can be seen that certain upper limb rehabilitation robots have large structures and complex systems, and their application scope is limited; most domestic rehabilitation robots have fewer degrees of freedom and can only provide rehabilitation training for single joints or a few degrees of freedom, especially for the shoulder, which has a small spatial range, too low range of motion and amplitude, and a single mode of motion, and cannot complete a wide range of motion for certain joints, as well as a compound motion for multiple joints, thus failing to provide adequate stimulation of the central nerve. Conclusion:: The analysis shows that the existing upper limb rehabilitation robots are poorly adaptable and not well-suited for situations, such as for different patients and different recovery periods of the same patient. The upper limb rehabilitation robot solution needs to be more appropriately designed to meet all requirements in the rehabilitation movement of patients.
