Addressing the limitations of existing solitary elderly monitoring systems, this paper employs embedded technology, mobile communication technology, and artificial intelligence imageprocessing technology to develop a remote monitoring robot system for the children or guardians of solitary elderly individuals. This robot system aims to overcome the shortcomings of traditional fixed camera monitoring systems, achieving more flexible and efficient remote monitoring of the elderly with a cheaper solution. The hardware part of the robot system uses the CH32V307VCT6 microcontroller as the processor, combined with the HC-SR04 sensor for obstacle avoidance detection, utilizes an LED pillbox to remind the elderly to take their medication, employs a K210 camera module to monitor falling behavior, and achieves wireless communication through the esp8266 module. The hardware programming uses MRS IDE, the server side adopts Bafa Cloud and MQTT transmission protocol, and the mobile app is created through WeChat Developer Tools. At the same time, a vision algorithm based on deep learning is used to determine whether the elderly person has fallen. Test results prove that this intelligent monitoring system for the elderly, based on embedded technology, performs well in terms of real-time performance, accuracy, and stability.

Revolutionizing industries with aerial vehicles using mobile for surveillance is the proposed title of this paper. The availability of drones has created several opportunities, particularly in the areas of agriculture, transportation, and security. This study is a follow-up to the creation of a drone controlled by Wi-Fi-based UAV and advanced imageprocessing. To provide simple and seamless control, a mobile application has been released. Drone-taken photos and videos can also be processed and studied right away. Increasing the degree of autonomous vehicle operations, improving the accuracy of picture identification/analysis algorithms, and ensuring continuous communication between the drone and the control software are perhaps the key objectives of this work. The imageprocessing component aims to take into account sophisticated improvements such as terrain analysis, object detection, and anomaly detection, which are crucial, particularly in the context of security surveillance. Ensuring steady and long-range connectivity while taking certain environmental elements into account can be critical. Enhancing the imageprocessing technique to run smoothly on the off-board drone's hardware constraints is also a crucial step. However, integrating hardware and software continues to be a major challenge in the implementation of a dependable, high-accuracy, real-time analog-to-digital conversion system. The purpose of this research is to develop novel ways for improving UAV systems by integrating tough control systems with complicated image analysis capabilities. Keeping the aforementioned limits in mind, the purpose of this work is to improve understanding of how to create more self-sufficient and adaptive drones that can contribute to a broader range of professions or do more specific activities with minimal human interaction.

Lasers are imperative in quantum simulation experiments to trap and cool atoms. With the growing complexity of experimental setups, precise control and stability of the position and exotic shape of lasers have become essential for high-fidelity operations. However, disturbances such as temperature fluctuations, mechanical vibrations, deformation of materials, and acoustic noise pose challenges to fulfill these requirements. In this paper, we propose and evaluate the first system for stabilizing the laser's beam position using two high-resolution cameras with high frame-rates, and imageprocessing in a field-programmable gate array (FPGA) with low latency and subsequent in-loop feedback to the laser control. The proposed imageprocessing hardware extracts the Gaussian beam distribution from two 5 MP cameras at 47 fps and 435 ns latency. These are fed to four proportional-integral-derivative (PID) controllers implemented on the FPGA. The PID modules provide feedback through parallel digital-to-analog converter (DAC) channels for steering mirrors to stabilize the beam within 5 mu m accuracy. Using two cameras at distinct sample distances on the optical axis allows for controlling the incidence angle of the laser beam onto the image planes. The current system is a building block for future extensions allowing real-time phase-feedback on optical lattices, stabilization of independent optical tweezers in an array, and focus position stabilization of transverse electromagnetic (e.g. TEM01) modes enabling large-scale quantum simulations.

Running deep neural networks for large medical images is a resource-hungry and time-consuming task with centralized computing. Outsourcing such medical imageprocessing tasks to hybrid clouds has benefits, such as a significant reduction of execution time and monetary cost. However, due to privacy concerns, it is still challenging to process sensitive medical images over clouds, which would hinder their deployment in many real-world applications. To overcome this, we first formulate the overall optimization objectives of the privacy-preserving distributed system model, i.e., minimizing the amount of information about the private data learned by the adversaries throughout the process, reducing the maximum execution time and cost under the user budget constraint. We propose a novel privacy-preserving and cost-effective method called PriCE to solve this multi-objective optimization problem. We performed extensive simulation experiments for artifact detection tasks on medical images using an ensemble of five deep convolutional neural network inferences as the workflow task. Experimental results show that PriCE successfully splits a wide range of input gigapixel medical images with graph-coloring-based strategies, yielding desired output utility and lowering the privacy risk, makespan, and monetary cost under user's budget.
