Lower-limb assistive wearable exosuits can reduce occupational injuries of manual workers by assisting strenuous and repetitive lifting tasks. This study aims to develop a lower-limb assistive wearable exosuit using a mechanism called SwitchSpring to assist users during lifting. The base structure of the SwitchSpring functions as a spring rod and can switch between rigid and soft states by adjusting the cable tension on the rod. When the SwitchSpring is switched to its rigid state, the energy is harvested and released as the user squats down and stands up. The lower limb joint angles and muscle activations of a female subject lifting a 5 kg box with and without the device were measured. The results show that the SwitchSpring wearable robot manages to reduce the muscle activation level by up to 30% on the rectus femoris (RF), 35% on the biceps femoris (BF), and 37% on the tibialis anterior (TA), showing the potential of lower limb power assistance in lifting. © 2024 IEEE.

Raman spectroscopy, a non-destructive chemical analysis technique, is an extremely useful chemical identification tool that provides detailed information about the chemical structure. However, some challenges are inevitable in practical applications, mechanical and electromagnetic noises, fluctuations in laser light, and background fluorescent signal;especially, variance is observed for the same substance under different environmental conditions. In this study, a small-step center weighted moving average (CWMA) algorithm was used to process the Raman spectra of pesticides to obtain optimized spectral data. Then the EAN-13 international universal barcode was used as the carrier of detection information to generate barcode images by adopting the python-barcode function library. In this study, the pesticide barcode database was established with the Raman detection platform. © The Author(s), under exclusive license to Springer Nature Switzerland AG. 2024.

This work investigates the position control in Cartesian space of a soft continuum manipulator with pneumatic actuation. To this end, we employ a feedback integral action initialized using an optimized mapping between pressure and tip position. This approach is detailed for a manipulator consisting of either a single actuated segment or of two actuated segments connected in series. Experiments are conducted on individual prototypes and with a teleoperation setup including a master unit from our track record. © 2023 IEEE.

The human brain can effortlessly imagine a 3D image from only 2D images with a little expertise and imagination, but for machines, this is not a trivial task. Because of this, reconstructing 3D images from 2D ones is a hot topic and has many applications. In this paper, we propose a Generative Adversarial Network (GAN)-based approach that generates CT-like images using pairs of orthogonal X-ray projections taken from different angles. In this work, a variety of orthogonal pairs from different angles, ranging from 0 &90 to 60 &150, were considered as input to the 3D image generation model. The effectiveness of the proposed method was assessed by measuring the Structural Similarity Index (SSIM) and Peak Signal-to-Noise Ratio (PSNR), which resulted in values of 0.641 and 29.21, respectively. Furthermore, the model's ability to capture the respiratory motion in the input projections and reflect it in the generated images was also assessed. This work demonstrated the feasibility of generating CT-like images from X-ray projections captured from different orthogonal angles taking into consideration the respiratory motion exhibited in these projections. © 2023 IEEE.

Determining the life stage of animals is crucial for assessing their overall health and making informed decisions for their care. However, traditional veterinary practices often rely on subjective methods, resulting in fuzziness or ambiguity. A quantitative metric via measurable vital signs has yet to be developed, which could be due to lack of a sophisticated methodology that can correlate the vital signs with age. To tackle this challenge, we present a method for equine life stage (young to old) classification from photoplethysmography (PPG) waveforms collected from 50 equine subjects with various ages, sex, and breeds. The data were collected using compact, wearable PPG sensors on their tails. The collected waveforms served as the input for the classification by an echo state network (ESN). It was found that the classification accuracy depended on the age split, suggesting a fussiness in classifying the youth and elder. Using the 17th year as the splitting age, the highest training and testing accuracies of 81.3% and 81.1% were achieved, respectively. In addition, input features from the reservoirs of the ESN were extracted and analyzed by a kernel principal component analysis, which afforded a 3D PCA map with clear clusters according to the age groups. This suggests that the ESN can learn hidden information from the PPG waves to classify the life stage. The proposed algorithm exhibits immense potential in veterinary medicine by offering a more objective and reliable approach to animal life stage assessment. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.

In this paper a new variant of the widely used Rapidly exploring Random Tree (RRT∗) algorithm is proposed. The main goal of this variant is to improve the efficiency of the generated path, in both computation time and the quality of the path. In a previous work by the authors, an improved version RRT∗N was proposed, where a normal probability distribution was used to control the generation of the random nodes. The proposed variant utilizes an intelligent fuzzy logic system (FLS) to control the generation of the random nodes and commands the robot to the required target introducing an intelligent fuzzy adaptive RRT∗N path planning approach (FA-RRT∗N). The proposed approach not only reduced the time required about 29.5 % of the time required by the RRT∗, but also generally resulted in shorter path about 63% of the path generated by the traditional RRT∗. © 2023 IEEE.

The accuracy of pulse and tissue oximeters has been questioned due to potential bias related to skin pigmentation. Current commercial oximeters use a limited number of wavelengths to estimate tissue blood oxygen saturation (StO2), failing to account for additional light absorption caused by melanin which particularly important in individuals with darker skin. This limitation has resulted in inaccurate readings, missed diagnoses, and delayed treatment for these people. Interestingly, the absorption spectrum of melanin in the near-infrared region decreases quasi-monotonically with wavelength, similar to light scattering, which can be effectively mitigated by applying spectral derivatives to hyperspectral near-infrared spectroscopy (h-NIRS) measurements. Consequently, we hypothesize that h-NIRS can mitigate the confounding effects of melanin, to provide more accurate measurements of StO2 across diverse skin tones. This study evaluates the accuracy of h-NIRS in comparison to few-wavelength spectroscopy (i.e. simulated commercial tissue oximeters) through simulations and tissue-mimicking phantom experiments. The accuracy of h-NIRS for determining StO2 was assessed against two "virtual devices", each mimicking a commercially available tissue oximeter (INVOS-5100c and NIRO-200NX). Results showed significant skin tone-dependent biases of the simulated commercial devices, while h-NIRS demonstrated consistently low errors ( © 2025 SPIE.

This study aims to give an accurate estimate of the effective thermal-mechanical properties of a coreless circuit substrate for advanced IC packages. To achieve the goal, a subdomain-based effective method is proposed, incorporating a sub-domain three-dimensional (3D) copper trace mapping and modeling (TMM) method, a volume-averaging rule of mixture (ROM) technique and finite element modeling. Furthermore, the proposed effective method is combined with an FEA-based process simulation framework to investigate the process-induced warpage of a flip-chip chip scale package during fabrication. At last, parametric analysis is performed to identify the crucial factors influencing the process-induced warpage of the package. © 2023 Japan Institute of Electronics Packaging.
