Musculoskeletal disorders (MSDs), often caused by working in non-ergonomic circumstances, are the most important category of work-related diseases. Different methods exist for examining ergonomics through a variety of postural evaluation techniques (e.g. Rapid Entire Body Assessment (REBA)), which are mostly performed through manual survey-based observations. Consequently, measuring ergonomics of operators is time-consuming and happens only sporadically, often after problems occur. Furthermore, as an ergonomist must assign a score to the performed activity, the ergonomics evaluation is subjective. These problems can be resolved by continuous and automated ergonomic load monitoring methods that directly provide feedback to operators. In order to monitor the operator without interfering the task at hand, a vision-based ergonomics monitoring system is developed. Here, ergonomic features (e.g. joint angles) are estimated based on multiple video streams, which are used to calculate an objective ergonomic score using a standard ergonomics evaluation technique. Although cognitive operator support systems (i.e. digital work instructions) for manual assembly environments are widely used, they do typically not include ergonomics information. The goal of the methodology presented in this work is to a) formulate or update digital work instructions, b) provide the operator feedback on its ergonomic soundness via work instructions and c) generate ergonomic risk level reports in an automated way based on the outcomes of the vision-based ergonomics evaluator. Making the ergonomic guidelines context-aware ensures that interventions occur at the right time. The methodology is integrated in a framework for context-aware work instructions and is validated via a proof of concept, based on an actual industrial case. Results show that context-awareness enhances user acceptance and ergonomics of the operator. © 2022 Elsevier B.V.. All rights reserved.

The lack of design methodologies integrating sustainability into the design processes of medical devices has been identified as a hindrance in developing sustainable solutions. This research aimes to overcome this by creating such a methodology, developed through a “Research through design approach, incorporating design for Sustainability (D4S) into the design process applied at the ULB BEAMS research group. As an illustration, this methodology was used in the development of electroencephalogram (EEG) dry electrodes. A simplified Life Cycle Assessment (LCA) was utilized to quantify the environmental impact of the final concepts. These calculations showed a significant reduction in $\mathrm{C}{{\mathrm{O}}_{2}}$ emissions of the final concept, a filled silicone electrode (at the embodiment design phase), compared to initially developed EEG electrodes, a coated silicone electrode (developed without the sustainable design methodology). Methodologically considering sustainability throughout the design process of medical devices can thus help achieve preferable outcomes. Further research is proposed to refine the methodology, explore variations in the implementation of medical device design processes, conduct additional case studies, and develop a new quantification tool to assess the full impact of medical devices. Overall, the paper highlights the importance of integrating sustainability into medical device design to effectively address environmental and potentially social challenges.

Software plays a key role in modern automated systems. Testing the control software is one of the final steps in the development process and when done on the physical set up, it creates risks (e.g. project delay, system damage and operator injury). In addition, with flexible systems it is almost impossible to test every possible scenario on the real system. Using a digital model allows testing different configurations before the physical hardware is available and thus without risk for the operator and the system hardware. A digital model of the reconfigurable system can also help validate new configurations virtually while the real system still operates in its current configuration, allowing for a quick risk-less changeover. Depending on the level in the control hierarchy, the simulations can run faster than real time. This paper demonstrates the use of a digital model during the commissioning at different levels. On each level, other requirements need to be fulfilled and a different level of detail is needed in the model. Every level asks for a different set of input data, that needs to be consistent to result in a reliable emulation/simulation. The methodology is evaluated on a reconfigurable assembly system, consisting of multiple base units with modular, relocatable add-on modules. The most detailed level is the process and machine level, considering the low-level control logic, movements of the machine and robots, collisions, etc. Cell and plant level commissioning focuses on the interaction of multiple machines, transport, production schedule and assignment of tasks to the individual machines. This level typically covers a longer time span and requires less detail of the actions on the machine level. It interacts with higher level control software and a simplified version of the low-level control logic is implemented in the model itself. This paper describes the methodology and lessons learned to reuse the digital model at different levels of the control hiera

Microneedles (MN) are micron-sized devices used for transdermal delivery of a variety of active pharmaceutical substances with minimal pain. MN eliminates the issues such as trypanophobia which is the fear of needles and injections, by providing a pain-free experience. Moreover, it can also be used as an alternative for oral drug delivery (ODD) and the complications associated with an ODD route. Also, the MN technique avoids passing through some human organs such as kidneys and liver and reduces the risk of transmitting infection into the body. The applications of MN include immunization, cosmetics, therapy, sample extraction, cancer treatment, wound healing, and disease diagnostics applications. In this research, our group proposes an additive manufacturing (AM) technology: stereolithography (SLA) for the fabrication of MNs for transdermal drug delivery purposes. The advantages of AM technology include high resolution, low cost, and lower fabrication time. We propose to improve the printing accuracy of the microneedle compared to the original computer-aided design (CAD) model and produce a high-quality microneedle array. In this study, a 10 x10 conical microneedle array with different aspect ratios using the stereolithography (SLA) method was fabricated. MNs were characterized using a scanning electron microscope (SEM) and an optical microscope. SEM and optical microscopy analyses were conducted to evaluate the morphology and quality of printed microneedles. A single microneedle array took about 20 minutes for 3D printing. The diameter and height of the microneedles were within 10% and 15% of the original CAD specifications, respectively. This research work establishes a framework for optimizing the 3D printing process parameters for fabricating microneedle arrays. © IISE and Expo *** rights reserved.

New technologies are being used in industry automation, like service, and communications. Industry 4.0 is the next fourth industrial revolution that promotes organisational effectiveness. Automation is an exponentially growing field with various challenges. Robotic arms also known as articulated robotic arms, are widely used in the process of automation in industry 4.0. The main function of automation using robotic arms is to perform a given task repeatedly, which is greatly reducing the manual efforts and increasing the efficiency of the task performed. This paper consists of the development of a three-axis robotic arm for industry 4.0, which performs the instantly learned task repeatedly. This is designed using a servo system for more accuracy and an analog system to control the servo system using an Arduino UNO microcontroller. The designed 3-axis robotic arm performs various operations and basic services which may be difficult for human being to do so and shows accurate and fast performance in industry operations to enhance more productivity. © 2023 IEEE.

As the amount of product iterations within high variety low volume assembly environments increases, the need for efficient management of variability and engineering changes within assembly instructions rises. This work proposes a methodology and a system architecture that facilitates the interplay between product lifecycle management (PLM) systems and digital assembly instructions, using an ISA-95 based data model. The framework consists of three main components: (1) a product variability model that integrates PLM information, (2) a digital instructions authoring tool, and (3) an assembly instruction variability model that connects to instruction platforms. Finally, the approach is applied to a validation case.

Reconfigurable assembly systems (RAS) are designed to operate in highly volatile market environments, which establishes the need for constant redefinitions of the production planning activities. These planning activities are usually modeled as complex mathematical optimization problems, and as such, increased responsiveness of the system will be directly linked to the prompt and efficient solution of these problems. In this work, we investigate the use of Per-instance algorithm configuration (PIAC) methods to select, at runtime, the best configuration of an algorithm designed to solve these optimization problems. We compare and evaluate the performance of Hydra, a state-of-the-art PIAC method designed for heterogeneous instance spaces, and a simpler Case Base Reasoning (CBR) approach to PIAC. Our experiments suggest that CBR methods for PIAC could be more suitable to highly homogeneous instance spaces, such as those observed in a RAS context, with reductions of up to 17% over the default algorithm configuration settings.

This paper proposes a two-phase boost converter using an integrated winding coupled inductor (IWCI) that achieves high-power density and common-mode (CM) noise reduction. As an attractive feature of the proposed circuit using IWCI, two output diodes are eliminated compared to the conventional circuit using loosely coupled inductor (LCI) and symmetry-balanced technique. The CM noise of the proposed converter is effectively reduced by fulfilling the balancing conditions derived from the CM equivalent circuit. Additionally, components are inherent to the circuit, and it can be done without compromising other design parameters or requirements. To confirm the validity of the derived balancing conditions, experimental evaluations are carried out by using a 300W prototype of the proposed circuit using Gallium Nitride (GaN) devices. The experimental results demonstrated a significant common mode noise reduction effect, achieving up to 50 dBµV across a frequency range of 1 MHz to 30 MHz compared to conventional circuits.
