This study introduced a capacitive sensing interactive game platform aimed at promoting emotional stability, which we have named the 'Sunrise and Sunset' game. This game primarily consists of two pieces of regular textile fabric enveloping conductive silver fabric. A microcontroller was employed to extract the sensed capacitive values, and a game named 'Sunrise and Sunset' is designed to complement the slow raising and lowering of both hands. The development of this gaming platform has the potential to offer a novel method of emotional management, particularly in high-stress living environments. It can serve as an effective relaxation tool, aiding individuals in emotional balance, anxiety reduction, and stress alleviation. Simultaneously, this platform can contribute to the promotion of mental well-being, providing an engaging and beneficial means for people to manage their emotions and moods. © 2024 IEEE.

Arm-based electrocardiogram (ECG) offers a more comfortable and user-friendly alternative to traditional chest ECG for wearable cardiac monitoring in daily health applications. However, arm ECG faces challenges such as capturing extremely low-amplitude signals in the microvolt range and significant electromyogram (EMG) noise contamination. The aim of this study was to evaluate the performance of dry electrodes for arm and chest ECG monitoring using gold standard BIOPAC and proposed mDAQ systems. This study consisted of two phases. In Phase 1, we evaluated different dry electrode materials, including silver knit fabric and gold-plated electrodes, with six healthy adult participants (N = males and N =3 females) having upper arm circumference ranging from 27 to 42 cm. We used a BIOPAC system as a gold standard to collect arm ECG, upper arm EMG, and reference chest ECG during standardized movement tasks. Results showed that silver knit electrodes demonstrated superior QRS energy (0.705 ± 0.151), surpassing chest gel floating ECG QRS energy (0.328 ± 0.026), with lower EMG interference across movement conditions. In Phase 2, we developed a bioinstrumentation system (mDAQ) optimized for dry electrodes, demonstrating reliable ECG acquisition in both chest Lead I and arm configurations. -We validated our bioinstrumentation with sixteen healthy adult participants (N = 8 male and N = female. The mDAQ system maintained high signal consistency with a skewness effect size of 0.963 and showed a mean heart rate bias of only -1.842 bpm compared to the BIOPAC system, confirming its viability for wearable ECG monitoring applications. © 2024 Fraunhofer IZM.

In spatial frequency domain imaging (SFDI), tissue optical properties are estimated by projecting spatial frequencies on the tissue and measuring back-scattered reflectance. We characterize the measurement error in camera-defocused SFDI and evaluate 1) dividing the defocus response and 2) cubic phase mask approaches in recovering SFDI performance. Camera-defocused SFDI underestimates tissue optical properties and loses spatial resolution. Both methods are shown to double the object distance range over which optical property measurements are within 25% of best focus values, though spatial resolution is lost. This work extends SFDI’s potential applications to remotely monitoring cardiovascular health in clinics and homes. © 2025 SPIE.

Cone-Beam Computed Tomography (CBCT) provides superior image quality in dentistry, but involves higher radiation exposure. To address this, lower radiation levels in CBCT imaging are used, resulting in higher noise levels. Although numerous efforts have been made to improve the visual quality of low-dose CBCT images, they often fail to achieve an optimal balance between noise reduction and edge preservation. This paper introduces a novel denoising algorithm surpassing previous methods, aimed at enhancing diagnostic accuracy by improving visual quality. Our approach begins with an adaptive median filter, followed by a fusion of frequency and spatial domain filtering techniques, supplemented by nonlocal means (NLM) smoothing and Laplacian sharpening. Subjective evaluations show a significant performance improvement over current state-of-the-art methods, marking a substantial progress toward achieving visual fidelity parity between low and high radiation CBCT scans. © 2024 IEEE.

Modern industrial pollution requires proactive measures to mitigate its environmental effects. This paper advances eco-friendly production forecasting using IoT and Logistic Regression (LR). Optimizing output, reducing pollution, and minimizing industrial activities' environmental imprint are goals. Industrial IoT sensors keep track of energy consumption, raw material use, and pollution in real-time. Processing and analyzing this data identifies production patterns and trends. LR is used to predict production factors and pollution levels. The model's use has several advantages. First, it provides real-time production environmental effect data. This lets firms alter production on the go, optimizing resource use and reducing emissions. The system can estimate future pollution levels based on projected production scenarios, enabling proactive pollution management and environmental compliance. LR and IoT enable sustainable industrial production. Company eco-friendly policies, waste reduction, and manufacturing efficiency may be improved by recognizing pollution drivers. This method supports global sustainability and environmental preservation. This technology is shown to revolutionize industrial pollution management, decrease ecological damage, and encourage environmentally aware production forecasting. It's a promising move toward eco-friendly production and meets the rising need for a responsible and sustainable industry. © 2024 IEEE.

This paper investigates the selection of the optimal number of modules in an Input-Series-Output-Parallel (ISOP) LLC resonant DC-DC converter for motorsport applications. The study employs a Genetic Algorithm (GA) multi-objective optimization of the High Frequency Transformer (HFT) power losses and total volume. The analysis is repeated for converters with different numbers of modules, considering both commercially available and custom transformer cores, as well as air and water cooling systems. The Pareto front of solutions is determined and presented in each scenario. Optimization results indicate that for commercial cores, the range of optimal solutions is significantly constrained by thermal limitations. Conversely, a wider range of solutions can be obtained with custom cores. Furthermore, a lower number of modules is preferable for achieving high efficiency. On the other hand, increasing the number of modules can increase the converter power density, although this results in lower efficiency. © 2024 IEEE.

Obstructive sleep apnea (OSA) has become more common in recent days due to overweight, obesity, stress, and depression. It is a serious disorder where the patient's breathing repeatedly stops and starts. It is linked to social, economic, and health consequences. Due to the complicated design of the existing work, a new design of a simplified Continuous Positive Airway Pressure (CPAP) device with LabVIEW software has been proposed. In lab view software, the different virtual components like the blower, relay, and respiratory sensor will be placed. First, the virtual patient is positioned in virtual LabVIEW to check whether the patient is affected by OSA or a normal level patient. The blower is mainly used to level the flow of air (i.e., inhale and exhale). Further, the relay is employed to provide a time delay function, and it is utilized to control high-voltage and current circuits. In LabVIEW, the breathing level and threshold level frequencies are fixed with the aid of a respiratory sensor. The key aim of this proposed work is to control OSA patients. If the patient suffers from OSA, the respiratory sensor can supply the air pressure to the OSA patients based on different respiratory rate ranges. © 2024 IEEE.

Quantifying temporal intensity fluctuations is crucial yet challenging in many biomedical applications, e.g., assessing blood flow, tissue perfusion, and particle sizing. These fluctuations arise from dynamic scattering processes within biological tissues and are commonly characterized in the time domain by the intensity autocorrelation function g2(τ ). However, measuring g2(τ ) across a wide field of view often requires short exposures (high frame rates) or specialized high-speed cameras to capture rapid dynamics. In this work, we propose two wide-field speckle-based approaches for quantifying temporal intensity fluctuations using only standard cameras. Different from the existing laser speckle contrast imaging approaches which keep the laser intensity a constant within camera exposures, we modulate the laser intensity (temporal modulation) within camera exposures. With the temporal intensity modulations, we show that the speckle contrast can be taken as a sampling of g2(τ ) or the power spectrum density functions of the temporal intensity fluctuations. We validated the performance of the proposed approaches on blood flow imaging using both microfluidics phantom and mouse cranial windows. Experimental results demonstrate the effectiveness of both approaches in accurately quantifying temporal intensity dynamics. The proposed laser intensity modulation speckle imaging enables 2D wide-field quantification of fast temporal intensity fluctuations with significantly reduced instrumental costs associated with high-speed cameras. © 2025 SPIE.
