Repetitive therapy can improve dexterity and hand movement among the paralyzed and stroke affected patients. The assistance of simple robotic technology may enhance the recovery rate of such patients. The study aims at developing a low cost bionic glove rehabilitation device which aids in providing effective finger exercises for physiotherapy by the use of a potentiometer. The prototype is designed in the form of a wearable glove for easy use. It includes an ATMEGA-328 microcontroller that is programmed using Arduino software for controlling the device. The motion of the fingers during therapy is achieved using a metal gear servo motor while the linear potentiometer controls the angle. This device can be used in rehabilitation to provide repetitive therapy for fingers at home with limited supervision by the physiotherapist for the paralytics. The performance of the device is simulated and evaluated using the Proteus Intelligent Schematic Input System (ISIS) software. The results obtained from the simulation can be used to improve the features of the device for effective practical implementation.

AbstractSmartphone microscopes can be useful tools for a broad range of imaging applications. This manuscript demonstrates the first practical implementation of Microscopy with Ultraviolet Surface Excitation (MUSE) in a compact smartphone microscope called Pocket MUSE, resulting in a remarkably effective design. Fabricated with parts from consumer electronics that are readily available at low cost, the small optical module attaches directly over the rear lens in a smartphone. It enables high-quality multichannel fluorescence microscopy with submicron resolution over a 10× equivalent field of view. In addition to the novel optical configuration, Pocket MUSE is compatible with a series of simple, portable, and user-friendly sample preparation strategies that can be directly implemented for various microscopy applications for point-of-care diagnostics, at-home health monitoring, plant biology, STEM education, environmental studies, etc.

Abstract. This study introduces a new control method for electromyography (EMG) in a prosthetic hand application with a practical design of the whole system. The hand is controlled by a motor (which regulates a significant part of the hand movement) and a microcontroller board, which is responsible for receiving and analyzing signals acquired by a Myoware muscle device. The Myoware device accepts muscle signals and sends them to the controller. The controller interprets the received signals based on the designed artificial neural network. In this design, the muscle signals are read and saved in a MATLAB system file. After neural network program processing by MATLAB, they are then applied online to the prosthetic hand. The obtained signal, i.e., electromyogram, is programmed to control the motion of the prosthetic hand with similar behavior to a real human hand. The designed system is tested on seven individuals at Gaziantep University. Due to the sufficient signal of the Mayo armband compared to Myoware sensors, Mayo armband muscle is applied in the proposed system. The discussed results have been shown to be satisfactory in the final proposed system. This system was a feasible, useful, and cost-effective solution for the handless or amputated individuals. They have used the system in their day-to-day activities that allowed them to move freely, easily, and comfortably.

Using QR codes to access videos in engineering laboratory classes might be a successful way of building a bridge from concrete to digital content. With QR codes placed on an apparatus, students know exactly which video to watch, allowing them to view the videos while performing the experiment or at home when writing the report. Low-cost videos do not require expensive equipment and software, and keeping them short assures a minimum download time for use with smartphones and tablets. The aim of this chapter is to evaluate the importance undergraduate engineering students attribute to these videos and their reaction to the possibility of accessing them with QR codes scanned by a smartphone or a tablet, using access statistics and video viewings to support the findings. Results show students attributed some importance to the videos, and that the QR codes are very helpful as means to quickly and easily access the videos.

This paper proposes a low-cost Light Emitting Diodes (LED) system with a novel arrangement that allows an indoor multi-robot localization. The proposed system uses only a matrix of low-cost LED installed uniformly on the ground of an environment and low-cost Light Dependent Resistor (LDR), each equipped on bottom of the robot for detection. The matrix of LEDs which are driven by a modified binary search algorithm are used as active beacons. The robot localizes itself based on the signals it receives from a group of neighbor LEDs. The minimum bounded circle algorithm is used to draw a virtual circle from the information collected from the neighbor LEDs and the center of this circle represents the robot’s location. The propose system is practically implemented on an environment with (16*16) matrix of LEDs. The experimental results show good performance in the localization process.

Motion Design

This paper presents a study of motion design and its implementation on a hybrid drive system that combines the motions of a large constant speed motor with a small servo motor by means of a mechanism in order to provide a powerful programmable drive system. In general, the most suitable function used to generate motion curves is the power form of polynomial functions. However, this function may produce some unexpected oscillations between the boundary conditions. A methodology is given to prevent this drawback of the interpolation function. A laboratory type set-up is designed and manufactured in order to realize the problems of practical implementation. An experimental application involving the hybrid drive system is included in the study presented.

Aldehyde Emission

Ever since the energy crises in 1970s, the methanol, among other alternative fuels, has been studied for automotive application. The methanol has been widely used for auto racing due to its superior anti-knock characteristics. However, aldehyde is a highly toxic pollutant and aldehyde emission out of alcohol fuel combustion could be considerably higher than spark-ignited gasoline engines. The corrosion and durability of methanol fuel components were also concerns for mass production of methanol-fueled vehicles. The authors have worked with an automotive manufacturer in China to investigate the brake thermal and emission improvement potentials of a methanol-fueled, spark-ignited engine over the original gasoline engine on a passenger car application and to demonstrate the performance and China V emission compliance over its useful life of 160,000 km. The study found that the methanol-fueled engine has 4%–6% brake thermal advantage over the original gasoline engine, and a three-way oxidation catalyst has successfully managed the tailpipe emissions under China V emission limit, consistently over the journey of 160,000 km. The test data show that the tailpipe aldehyde emission is actually reduced to a level that is below what is required by US LEV III emission standard, largely due to the three-way oxidation catalyst and the gasoline cold start assistance at the beginning of the transient emission cycle. This study indicates that methanol-fueled engine might be an attractive low-cost alternative for a more efficient and clean powertrain over conventional gasoline when a light-duty diesel engine faces challenges from future China VI emission regulations.

The general Latin American population with a physical disability or limited mobility has faced the daily basis challenge of having autonomy in home activities, with low-income or almost no-income. Needy Brazilian communities are examples of poor populations suffering from the lack of autonomy at home, aggravated by scarce financial resources. The authors developed a low-cost home automation system, aiming to assist people who live in Palmeira dos Indios city and Arapiraca city, needy communities located in the Northeast of Brazil. The system is composed of hardware and software components. The hardware comprises of microcontrollers used to actuate over electrical devices at home, while an Android application provides a simple graphical user interface (GUI) to control the devices using touch and voice commands by Bluetooth communication. They evaluated the system by implementing a home model and providing the home for four physical disability persons and one limited mobility person. They considered the system`s effectiveness, the system`s usability, and users` perceptions during the evaluation.
