Cyber-physical systems combine computational, communication, and physical components. They are employed in many fields, such as manufacturing, transportation, and robotics. CPS's master side overseas, directs, and organizes the entire system. Usually, it provides instructions to actuators on a slave side which gathers information from sensors on the physical parts and sends them back to the master side to control the overall system behavior. Building a CPS system for research purposes is not a simple task, using simulations is a viable choice to explore the possibility and feasibility of such systems before building them. In this work, we suggest the utilization of the simulation tool Modelica to build the master side of a CPS system. This mainly consists of a haptic interface that can manipulate and intervene in a distant physical system, through the slave, while feeding back the force-torque information from the slave. Modelica's choice is based on this software's electromechanical simulation capability. The result of the work shows the utility and usefulness of the simulation tool to generate force signals for the remote end control while receiving torque feedback to simulate the kinesthetic feeling of a haptic interface.

This paper studies the trajectory tracking problem of the unmanned surface vehicle with sensor deviation faults. Firstly, the trajectory tracking controller based on model predictive control is designed according to the physical characteristics of the unmanned vehicle system. Moreover, an event trigger mechanism is explored in the controller to reduce the waste of computing resources. Then, a H ∞ fault estimator is designed to accurately estimate the value of sensor deviation faults. Finally, the influence of sensor faults on the designed controller is analyzed. At the same time, the faults information was used for improving the tracking performance. The proposed trajectory tracking method with the fault-tolerant algorithm is verified by simulation examples.

In today’s computer systems, the mouse is an essential input device. Touch interfaces are high-contact planes that we use on a regular basis and frequently throughout the period. As a result, the input device gets infested with bacteria and pathogens. Despite the fact that wireless mouse have eliminated the bunch of tangled wires, there is still a desire to tap the gadget. In light of the epidemic, this proposed method employs a outlying webcam or an in-built image sensor to capture arm gestures and identify fingertip detection, allowing users to execute standard mouse activities such as left click, scrolling and other mouse activities. The algorithm is trained using machine learning with the use of image sensor and the fingers are identified efficiently. As a result, this reliance on corporeal devices to manage the computational system cancels out the requirement of man-machine interface. Thus the suggested approach will prevent the proliferation of Covid-19.

Brain-computer interface (BCI) provides a direct pathway from the brain to external devices, which have demonstrated potential in rehabilitation and human-computer interaction. One limitation of current BCI lies in the low precision and stability in control, thus the user scenario and the interaction process play an important role in BCI applications. We propose to leverage the ability of artificial intelligence (AI) to improve the easy-of-use of BCIs. We designed a brain-controlled mahjong game with AI augmentation. As the user plays the game, an AI system continuously monitors the game and suggests several optimal candidate options, and the user directly selects from the candidates rather than from all the mahjong tiles in hand. This design enables the mahjong game with easy control, thus improving the user experience. Our system is evaluated by a human subject with an invasive BCI system. Results demonstrate that the subject can fluently control the system to play the mahjong game.

The human population is only growing, and certain steps are to be implemented to meet the future requirements with respect to food. This paper discusses the implementation of a smart farm using Internet of Thing. IoT has led to a faster form of gathering data and inferring from our surroundings. A farmer, with the help of this smart farm system, will be able to keep track of plant and soil vitals in real-time and use the recommendation system, based on a model trained from a dataset, to suggest the best suitable crop based on sensor values. IoT-enabled Smart Farming will enable growers and farmers to enhance productivity and reduce the wastage of resources. The proposed system is a more reliable concept and can be easily implemented as it consists of sensors that can collect vital information about the environment from soil nutrients, temperature, humidity, and soil moisture regularly which is displayed on an easy-to-understand interface to be interpreted by the growers and farmers to understand the best conditions to give their plants.

Recently, the automotive industry has increased rapidly and provided a number of efficient solutions for daily life, science, and manufacture. An auto-balancing system is such an automated solution that attracts much attentions from scientists and engineers. Designing a 3-dimension auto-balancing system is challenging in terms of accuracy, responsiveness, and noise reduction. In this paper, we introduce a model of a three-dimension auto-balancing system with high accuracy and low noise. We applies the inverse Kinematics for high accuracy of motor control and sensor fusion technique to reduce noise and increase reliability with sensor fusion of output data from sensors. The proposed system is built and simulated using Matlab model. Simulation results show that the proposed system can significantly reduce noise of sensors and achieve a response of fewer than two milliseconds.

Detectors applying sensor technology are popular with people. sensor technology is an advanced, scientific and intelligent technology, just like human sensory system, which can feel the changes of the external environment and then transmit the perceived external data to the computer. This paper discusses the application of sensor technology in automatic production line, and puts forward an automatic production line and controlsystem based on multi-sensor fusion algorithm. The simulation results show that with the increase of the quantity of experiments, the accuracy of the algorithm is stable at about 94%, and the real-time wavelength tends to be stable. Comparing the accuracy of the multi-sensor fusion algorithm with that of the traditional algorithm, it can be seen that the accuracy of the improved algorithm is obviously superior to that of the traditional algorithm. In order to improve the application level of sensor technology, technicians need to do further research on sensor technology, and better transmit, store, analyze and process information and data, so as to meet the development requirements of various fields.

Sleep apnea is a prevalent sleep disorder characterized by repetitive interruptions in breathing during sleep. Timely detection and monitoring of sleep apnea are crucial for effective diagnosis and treatment. We propose a novel approach for sleep apnea detection using Ultra-Wideband (UWB) sensor technology. The UWB sensorsystem offers several advantages, including high precision, low power consumption, and the ability to penetrate through different materials. By leveraging these features, we aim to develop a non-intrusive and cost-effective method to detect sleep apnea events accurately. Our research focuses on designing a wearable UWB sensor device that can be comfortably placed near the user’s sleeping area. The sensorsystem utilizes UWB technology to measure and analyze subtle movements and physiological signals during sleep, such as oxygen and heart rate variability. To detect sleep apnea events, we employ advanced signal processing algorithm, By extracting specific features from the UWB sensor data, we can identify the characteristic patterns associated with sleep apnea episodes. The proposed system has the potential to provide an accessible and effective solution for early detection and continuous monitoring of sleep apnea, leading to improved diagnosis, treatment, and overall patient care. Further research on creating a website for hospitals to monitor the apnea patients.
