DEVELOPMENT OF A MECHATRONIC GLOVE FOR SIGN LANGUAGE INTERPRETATION
ABSTRACT
Communication barriers between hearing-impaired individuals and the general public remain a major challenge, particularly in environments where sign language interpreters are unavailable. This study presents the design and development of a mechatronic glove for real-time sign language interpretation, aimed at enhancing accessibility and promoting inclusive communication. The glove integrates flex sensors, accelerometers, and pressure sensors to capture hand gestures and finger movements associated with common sign language symbols. Sensor data are processed using an embedded microcontroller, which applies a gesture-classification algorithm based on threshold analysis and pattern recognition. The interpreted gestures are then translated into audible speech output and text display through a wireless communication interface.
Prototype testing demonstrated an average gesture-recognition accuracy of 92.4% for the selected signs, with an average system response time of 0.8 seconds, indicating the glove’s potential for real-time application. Findings also showed that the device was lightweight, user-friendly, and adaptable to different hand sizes. The study highlights the potential of mechatronics and assistive technologies in bridging communication gaps for individuals with speech or hearing impairments. It recommends further development using machine learning models, extended gesture datasets, and enhanced wireless modules to improve robustness, speed, and scalability.
The mechatronic glove represents a practical, low-cost innovation capable of supporting inclusive communication in schools, hospitals, workplaces, and public service environments

INTRODUCTION
1.1 Background of the Study
The aerospace industry has witnessed significant advancements in materials technology over the past decades, driven by the need for improved performance, fuel efficiency, and cost-effectiveness in aircraft manufacturing. Traditionally, aluminum has been the material of choice due to its favorable properties, including its light weight, strength, and ease of fabrication. However, the growing demand for enhanced performance and efficiency has led to the exploration and adoption of composite materials, which offer unique benefits and pose distinct challenges.
Composite materials, typically consisting of a matrix (such as epoxy) reinforced with fibers (such as carbon or glass), have gained prominence in various sectors due to their exceptional strength-to-weight ratio, corrosion resistance, and design flexibility. In aerospace applications, composites have been increasingly used in components such as wings, fuselage sections, and tail assemblies. Their adoption aims to reduce weight, increase fuel efficiency, and enhance overall aircraft performance.
Despite their advantages, the use of composite materials presents certain drawbacks, including higher initial costs, complex manufacturing processes, and challenges related to repair and maintenance. These factors necessitate a comprehensive evaluation of the benefits and limitations of composites in comparison to traditional materials like aluminum.
The aerospace industry is continuously evolving, driven by the quest for innovations that enhance performance, efficiency, and safety in aircraft manufacturing. One of the most significant advancements in materials technology has been the shift from traditional metals, such as aluminum, to advanced composite materials. This transition is fueled by the desire to improve aircraft performance, reduce operational costs, and address the increasing demands for fuel efficiency and environmental sustainability.
Aluminum has long been the material of choice in aircraft manufacturing due to its favorable properties, including a high strength-to-weight ratio, excellent workability, and relative affordability. It has been used extensively in various structural components of aircraft, from the fuselage to wing assemblies. However, with the advancement of aerospace technology, composite materials, particularly carbon fiber-reinforced polymers (CFRPs) and glass fiber-reinforced polymers (GFRPs), have emerged as formidable alternatives. These composites offer remarkable benefits, such as enhanced strength-to-weight ratios, improved resistance to environmental degradation, and greater design flexibility.
Despite their advantages, the use of composite materials also introduces challenges. The complexity of manufacturing processes, higher initial costs, and issues related to repair and maintenance pose significant drawbacks.

Melon (citrulus Vulgaris or lanatus) is one of the most popular vegetable crops in Africa. It has tendril climbing herbaceous annual crop, which grows better in some part of the savannah belt region of Nigeria. The seed belongs to the cucumber family, which is used for extracting oil, and is popularly called ‘’egusi’’, a name widely used throughout West Africa. The crop had been in cultivation for at least 4000 years mainly for seed schippers. The crop does well on a sandy free chaining soil. It can also be planted as an intercrop with crops like maize, okro, cassava, yam because they are weed suppressors. When planted, it can be harvested between two and half to three months and with good management there can be a seed yield of 350 – 400kg per hectare. The main cultivars found in Nigeria are Bara, Serewe and Sofin. Bara also known as papa has large brown seeds with thick black edges thickened towards the apex, about 16 x 9.5mm and is common in the northern and western part of Nigeria. While Serewa seeds are smooth, light brown, with a light whitish edge that is not thickened about 15 x 9mm in dimension. They are mainly found in eastern Nigeria. Analysis made on melon by Ajilola et al (2011) indicates that melon seed consists about 50% oil by weight, 37.4% of protein, 2.6% fibre, 3.6% oil, 6.4% moisture. Out of the oil content of the seed 50% is made of unsaturated fatty acids which are Linolectic (35%) and oleic (15%) and 50% saturated fatty acids which are stearic and palmitic acid. The presence of unsaturated fatty acid makes melon nutritional desirable and suggests a possible hypocholestroleric effect (lowering of blood cholesterol). Research has shown that the consumption of melon seeds and its products reduces the chances of developing terra arterial or heat diseases. Melon has an amino acid profile that compares favourably with the soybeans and even white of egg. Also USDA Nutrient database has shown that melon is rich source of sodium (Na), Iron (Fe), Manganese (Mn), Copper (Cu), Zinc (Zn) and fat. The melon seed has a lot of advantages among which are the following: the oil extracted from it can be used in manufacture of margarine, shortening and cooking olis, while the residual cake is used for producing melon snacks known as ‘’robr’’. Despite the large productivity and nutritional benefit of this crop, there has been a hindrance to the use of melon for large scale production of oil and protein sources. This is as a result of the inability to process melon to meet the capacity required for industrial use over a specified period of time. The origin of the melon is Africa and Asia (Douglas, I982) and areas where it is widely cultivated include the Caribbean, Indonesia, and Africa. In Nigeria, the existence of melon dates back to the 17th century. Egusi belongs to a family of vegetables, or preferably pseudo-pulse crops known as Citrullus Lanatus. It is an important source of edible oil, vitamin E, protein, potassium, calcium magnesium, iron and sodium. Its soft cotyledon is encased in a hard outer shell. The cotyledon could have its edible oil extracted (44 to 50% oil content in seed), ground and used for sauces’ (36 to 60% protein content in seed), roasted or boiled and eaten. Egusi is a luxury; it costs $6 per kg after the coat is removed. All over Nigeria, egusi is eaten by those who can afford it. The factor that makes it so expensive is the time spent by women and children to dehull or shell the seed.
1.2 Statement of the problem
Though there are some experimental decorticators on trial, there are no efficient machines at EnuguNigeria to releave the process of dehulling by hand..This work has attempted a different shelling technique to bring a better efficiency at dehulling egusi. Egusi comes under the family of vegetables known as Cucurbitaceae, which are found mainly in the warmer parts of the world. They consist of 118 genera with about 825 species.
1.3 Objectives of the study
i. test the existing melon depodding machine and identify its deficiencies;
ii. carry out design modifications on the machine components to improve its performance;
iii. fabricate and assemble the modified components of the machine; and
iv. evaluate the performance of the machine in depodding freshly sliced, fresh and unsliced, and fermented pods.
1.4 Research Questions
i. test the existing melon depodding machine and identify its deficiencies;
ii. What are the design modifications on the machine components to improve its performance;
iv. What is the performance of the machine in depodding freshly sliced, fresh and unsliced, and fermented pods.
1.5 Research Hypothesis
H0: Modification does not have a significant impact on the productivity of the melon shelling machine
H1: Modification have a significant impact on the productivity of the melon shelling machine

HEART BEAT MONITORING SYSTEM WITH WIRELESS PC
CHAPTER ONE
INTRODUCTION
The heart is a muscular organ in humans and other animals which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, and also assists in the removal of metabolic wastes. It is located in the middle compartment of the mediastinum in the chest and it performs its functions with repeated heartbeats.
A heartbeat refers to a two-part pumping action of the heart that takes about a second. These are the diastole and the systole.
As blood collects in the upper chambers (the left and right atria), the heart’s natural pacemaker (the SA node) sends out an electrical signal that causes the atrium to contract. This contraction pushes blood through the tricuspid and mitral valves into the resting lower chambers (right and left ventricles). This part of the two-part pumping phase (the longer of the two) is called the diastole.
This is the second part of the pumping phase which occurs when the ventricles are full of blood. The electrical signals from the SA node travel along a pathway of cells to the ventricles causing them to contract. This is called the systole. As the tricuspid and mitral valves shut tight to prevent a backflow of blood, other valves open thus blood is pushed from the right ventricle to the lungs first to pick up oxygen before it is transmitted to the heart and other parts of the body.
1.1.3 Heartbeat Rate
The rate at which the heart beats is not constant. A heartbeat rate refers to the number of heartbeats per unit time, usually expressed in beats per minute (BPM). The heartbeat rate can vary according to the demands of the muscles to absorb oxygen and excrete carbon dioxide, thus, it changes during sleep and exercises. It also varies significantly between individuals based on age, fitness and genetics.
1.2 ELECTRICAL SYSTEM OF THE HEART
Fig 1.1 Electrical system of the heart (Culled from Google images)
The heart’s muscle is made of tiny cells and the electrical system of the heart controls the timing of the heartbeat by sending an electrical signal through these cells. Two different types of cell in the heart enable the electrical signal to control the heartbeat. These are:
This electrical signal travels through the network of conducting cell pathways which stimulate the upper and lower chambers to contract. The signal is able to travel along these pathways by means of a complex reaction that allows each cell to activate the one next to it, stimulating it to “pass along” the signal in an orderly manner. As each cell rapidly transmits this electrical charge, the entire heart contracts in one coordinated motion, creating a heartbeat.
The electrical system starts in a group of cells at the top of the heart called the “Sino-Atrial (SA) Node”. The signal then travels down the heart, triggering first the two atria and ventricles. In a healthy heart, the signals travel very quickly through the heart, allowing the chambers to contract in a smooth orderly fashion.
The heart’s electrical system controls the timing of the heartbeat by regulating:
The heart’s electrical system during normal functioning should maintain a heart rate of 60 to 100 beats per minute when a person is at rest. It increases this rate to meet the needs of the body during physical activities and lowers it during sleep. It also maintains an orderly contraction of the atria and ventricles. This is called “Sinus Rhythm”.
1.3 HEARTRATE MONITORING SYSTEMS
Generally, the patient monitoring system is one of the major advancements in the global health care program due to its improved technology. It is capable of measuring various body conditions of a patient like the temperature, heartbeat rate or the level of oxygen in the blood, using embedded technology. This advancement in technology was necessitated by the increased occurrence of cardio-vascular diseases which usually occur as a result of abnormalities in the heart condition of an individual (WHO, 2007). Obviously, it is difficult to keep track of the abnormalities in the heart by manual means, hence the need for heartbeat counters.
It is synonymous with a heart rate monitor hence these two terms will be used interchangeably throughout this project. Since the heart is one of the most important organs in the human body, it is imperative that these devices are designed with a very high degree of accuracy. Apart from construction defects and sensor technologies, the accuracy of the heartbeat counter depends on the part of the human body from which it is measured. The three most popular areas are the chest, the fingertip and the wrist.
1.3.1 The Chest
This is the most accurate means of heart rate monitoring as it remains very close to the heart. This type of monitor is strapped to the chest region with the help of appropriate support and it is linked to a display unit which displays the rate of the heartbeat. The display unit can be a simple monitor placed on a wristwatch, which signals by giving a beep sound when the heart rate crosses a certain limit.
1.3.2 The Fingertips
These may also be called pulse-type monitors and they measure the heartbeat rate when the finger is placed on it. This technology employs the use of optical sensors to measure the alteration in blood volume at the fingertips, with each heartbeat. This little alteration can be converted to a pulse, which is counted to determine the heart rate.
1.3.3 The wrists
These monitors operate on the same basic principle as the pulse-type monitors but their circuits are usually built into a wristband for the comfort of the user. Some wrist-based monitors utilise the pressure felt on the wrists with each heartbeat, to determine the heart rate. It is the least accurate type of monitor because by the time the blood reaches the capillaries in the wrists, it could have slowed down significantly. Most of them also require the user to remain absolutely still, while taking measurements.
1.4 PROBLEM STATEMENT
The human health is one of the most important concerns in the world today. Anything/everything becomes meaningless when one becomes sick and dies due to improper medical care. The heart is a very delicate organ in the human body (once it stops beating, nothing else matters). Thus, if early action actions are taken (and on time) the heart condition can be managed effectively and many patients can be cured and saved. The major problem is to reduce the rate of mortality due to heart failure among people.
1.5 AIM OF STUDY
The major aim of this project is to design and construct a digital heartbeat counter using a micro-controller, a sensor and a display, and capable of measuring the heart rate in beats per minute (BPM).
1.6 OBJECTIVES OF PROJECT
The objectives of the project are:
1.7 SCOPE OF PROJECT
This project is a simple university project and hence, it is not constructed with any intent for industrial application. The scope of this study is to design an efficient and cost-effective heart rate monitor using some electronic component such as microcontroller, operational LCD displays, phototransistors, e.t.c.
1.8 SIGNIFICANCE OF THE PROJECT
The main project objective is to monitor the human heartbeat and by so doing, the health condition can be determined. The significance of this project is thus:

CHAPTER ONE
The construction of a two-face gas burner as a project topic that we embark upon become necessary as a way of way of putting into application the engineering and technological knowledge acquired so far. It is a starting point of actualizing a functional technology in the country. Irrespective of the fact that there are several breads of gas burners in the market, especially the ones imported, we deemed it necessary to work further on it as a way of modifying the brand with cast not left out in such modification.
1.2 LITERATURE REVIEW
The development of simple gas burner started in the eighteen countries when people began to use coal gas for burning. The application was fast put into practice by William Mulock who designed the simple gas cooker to be used in his office, home and workplace
The first experimental gas cooker was made and in use in 1850. The improvement of this has multiplied greatly and is up to date widely used in homes, restaurants and large catering establishments. The different types of gas cookers available in the in the market are based on skills and techniques of the designer or producer.
Based on the nature of energy supply, some gas cookers are made up of combustion devices of an electric heating element. The well-constructed ones are properly adapted and form an integral combustion of which of which they generate and utilize heat. It is often quite different to draw a line where heat generation stops and where heat utilization starts in a fuel forced cooker. That is the fuel fired cooker being on the pack in the market these days.
The releasing of heart starts with mixture of air and fuel gas in the nozzle and combustion of the mixture to release heart takes place at the burner.
1.3 SPECIFICATION OF PROBLEM
In the course of fabricating the two-face gas burner, as a copied project with some propose modification, some condition which ought to be met are found as a standard of comparison with the already existing ones. This posed a difficulty in the course of this construction. Since choice between already existing gas cooker lies on service available, durability, connivance cost.
The following specifications were considered a problem when we started the design.
How to fabricate a two-face gas burner that will occupy the minimum space in the kitchen was a problem. A two-face gas burner that is easily to be met in met in our design.
THE BURNER: This being the main component where combustion takes place to release heat. There is gas delivery line, which leads to it in addition to an adjustment to control the rate of atmospheric air mixing with the natural gas

DESIGN AND FABRICATION OF A SOLAR GRAIN DRYER
ABSTRACT
Drying crops or grains by solar energy is of great economic importance the world over, especially in Nigeria where most of the crops and grain harvests are lost to fungal and microbial attacks. Proper drying could easily prevent these wastages, which enhances storage of crops and grains over long periods. India is blessed with abundant solar energy all the year round. Drying is one of the important and most energy consuming processes in the food- processing, chemical, printing, fabric dying industries, etc. In farmer level drying is being done on open yards without any good hygienic conditions. Generally thermal energy, maintained between 45 0C to 25 0 C depending on the products and production methods. A conventional fuel like electricity, firewood, diesel, furnace oil, kerosene, etc is producing that energy. The objective of this project is to modify design of a forced convection indirect solar dryer and its performance test on Grapes. The system consists of an air heating section. The solar dryer consists of different components such as solar panel, battery, heating element and blower. The blower is used to passing the hot air to the required place, so that the moisture contents in the place was removed. It offers a better control over drying and the product obtained is of better quality than sun drying. Solar Dryer Can be operated at higher temperature, recommended for deep layer drying.

CHAPTER ONE
1.0 INTRODUCTION
In the majority of countries, agriculture represents the biggest part of the economy. 80-90% of the working population is employed in agriculture. Despite these large numbers, national food production still does not meet the needs of the population. The lack of appropriate preservation and storage systems caused considerable losses, thus reducing the food supply significantly. The dent in food production caused by crop-failures as well as significant seasonal fluctuations in availability can be ironed out by food conservation, e.g., by drying. Sun drying of crops is the most widespread method of food preservation in a lot of countries due solar irradiance being very high for the most of the year. There are some drawbacks relating to the traditional method of drying, i.e., spreading the crop in thin layers on mats, trays or paved grounds and exposing the product to the sun and wind. These include poorer quality of food caused by contamination by dust, insect attack, enzymatic reactions and infection by micro-organisms. Also this system is labour and time intensive, as crops have to be covered at night and during bad weather, and the crops continually have to be protected from attack by domestic Animals. Non-uniform and insufficient drying also leads to deterioration of the crop during storage. Serious drying problems occur especially in humid tropical regions where some crops have to be dried during the rainy season. Traditional sun drying of sweet pepper and coffee. In order to ensure continuous food supply to the growing population and to enable the farmers to produce high quality marketable products, efficient and at the same time affordable drying methods are necessary. Studies have shown that even small and most simple oil-fired batch dryers are not applicable for the most farmers, due to lack of capital and insufficient supply of energy for the operation of the dryers.
The high temperature dryers used in industrialized countries are found to be economically viable in developing countries only on large plantations or big commercial establishments. Therefore the introduction of low cost and locally manufactured solar dryers offers a promising alternative to reduce the tremendous post harvest losses. The opportunity to produce high quality marketable products seems to be a chance to improve the economic situation of the farmers. However, taking into account the low income of the rural population in developing countries, the relatively high initial investment for solar dryers still remains a barrier to a wide application. 1.2 Solar radiation- The Energy Source For Solar Dry-ing The sun is the central energy producer of our solar system. It has the form of a ball and nuclear fusion take place continuously in its centre. A small fraction of the energy produced in the sun hits the earth and makes life possible on our planet. Solar radiation drives all natural cycles and processes such as rain, wind, photosynthesis, ocean currents and several other which are important for life. The whole world energy need has been based from the very beginning on solar energy. All fossil fuels (oil, gas, coal) are converted solar energy. The earth’s atmosphere is being changed at an unprecedented rate by pollutants resulting from wasteful fossil fuel use. These changes represent a major threat to international security and are already having harmful consequences over many parts of the globe. It is imperative to act now. So it’s the time that we have to make some alternatives that will be helpful for overcoming the shortage and need of today. That is why there are alternatives sources that we are using like solar energy, wind energy, geothermal energy etc.
1.1 BACKGROUND OF THE STUDY
Energy is the most important need of today’s society and economy. Our work, leisure, and our economic, social and physical welfare all depend on the sufficient, uninterrupted supply of energy. The energy demand continues to grow, year after year. Drying is one of the methods used to preserve food products for longer periods. The heat from the sun coupled with the wind has been used to dry food for preservation for several thousand years.
Sun drying is still the most common method used to preserve agricultural products in most tropical and subtropical countries. However, being unprotected from rain, wind-borne dirt and dust, infestation by insects, rodents and other animal, products may be seriously degraded to the extent that sometimes become inedible and the resulted loss of food quality in the dried Products may have adverse economic effects on domestics and international markets.
Solar thermal technology is a technology that is rapidly gaining acceptance as an energy saving measure in agriculture application. It is preferred to other alternative sources of energy such as wind and shale, because it is abundant, inexhaustible, and non-polluting. Solar air heaters are simple devices to heat air by utilizing solar energy and it is employed in many applications requiring low to moderate temperature below 80°C, such as crop drying and space heating.
In ancient times, the sun and wind would have naturally dried foods. Evidence shows that Middle East and oriental cultures actively dried foods as early as 12,000 B.C. in the hot sun. Later cultures left more evidence and each would have methods and materials to reflect their food supplies—fish, wild game, domestic animals, etc.
Vegetables and fruits were also dried from the earliest times. The Romans were particularly fond of any dried fruit they could make. In the Middle Ages purposely built “still houses” were created to dry fruits, vegetables and herbs in areas that did not have enough strong sunlight for drying. A fire was used to create the heat needed to dry foods and in some cases smoking them as well. [1]
The importance of food drying is likely to increase. The global population is predicted to exceed eight billion by the year 2025 (Cliquet and Thienpont, 1995). Food production must therefore be increased to meet the rising demand but this is unlikely to come from simply growing crops on previously uncultivated land (Dyson, 1996). One strategy to increase food supplies is to minimize crop wastage. In developing countries alone, the minimum estimates of post-harvest losses, including those from poor drying, vary between 10-20% (Pariser, 1987). A 1978 report by the National Research Council of the National Academy of Sciences in Washington, D.C., cited by Salunkhe and Kadam (1998), puts post-harvest losses as high as 30-40% in both industrialized and developing countries.
In addition to foods for human consumption, many other products require Drying. These include organic crops like timber and rubber and inorganic materials like this has focused our attention on energy intensive processes like drying where fossil fuels can often be replaced by renewable and non-polluting sources of energy. Drying paint. All of the above arguments emphasize the importance of drying in people’s lives.
However, according to Mujumdar (1990), “drying is the most energy-consuming industrial process”. It requires approximately 2.4 MJ to evaporate one liter of water. To dry one metric ton of most fruits in a conventional dehydrator to the safe moisture, content for long-term storage requires approximately 100 liters of oil. The shortage of energy is an issue in many countries, particularly those in the developing world. Even where conventional energy is plentiful, there is pressure to reduce the amount of fossil fuels used. Concern over global warming is universal and one metric ton of fruit in a conventional dehydrator produces approximately 300 kg of carbon dioxide. Technology the growers dry many crops at the point of production themselves so there is usually adequate land area available for the solar drying system.
Solar energy is an obvious energy source for drying various products, particularly food crops. Many crops are harvested in the summer months and are usually dried at temperatures below 700C – a temperature which can be readily attained by solar [2].
Some of the problems associated with open-air sun drying can be solved using a solar dryer, which comprises of collector, a drying chamber and sometimes a chimney.
Solar drying may be classified into direct, indirect and mixed-modes. In direct solar dryers the air heater contains the grains and solar energy passes through a transparent cover and is absorbed by the grains. Essentially, the heat required for drying is provided by radiation to the upper layers and subsequent conduction into the grain bed.
In indirect dryers, solar energy is collected in a separate solar collector (air heater) and the heated air then passes through the grain bed, while in the mixed-mode type of dryer, the heated air from a separate solar collector is passed through a grain bed, and at the same time, the drying cabinet absorbs solar energy directly through the transparent walls or roof.
1.2 PROBLEM STATEMENT
Solar air dryer is old concept, but in modern world many different parameters are been considered during its manufacturing. The design of solar dyer which gives some advantages as well as disadvantages such as friction losses ,vibration, expansion of acrylic glass due to heat and air flow, friction losses at the reducing cross- sections and leakages of air at small portions which cannot be identified . By considering all factors, we have taken decision to make solar food dryer, which is less costly, more efficient to poor people.
The objective of this study is to develop a mixed-mode solar dryer in which the grains are dried simultaneously by indirect radiation through the transparent walls and roof of the cabinet and by the heated air from the solar collector. The problems of low and medium scale processor could be alleviated, if the solar dryer is designed and constructed with the consideration of overcoming the limitations of indirect type of solar dryer. So therefore, this work will be based on the importance of a mixed mode solar dryer which is reliable and economically, design and construct a mixed mode solar dryer using locally available materials and to evaluate the performance of this solar dryer.

DESIGN AND CONSTRUCTION OF AUTOMATIC COIL WINDING MACHINE
CHAPTER ONE
INTRODUCTION
Typically, a winding machine winds a material such as metal wire, thread, or paper, onto a core, spool, or bobbin. There are several different types of winding machines, from simple manual feed machines to complex computer-numeric-control (CNC) machines. Some of the more common uses for winding machines are coil winding, rope winding, and continuous filament winding. Many industries use these devices, including textile, electronics, and wire industries. A manual winding machine usually has a core on a spindle and the user feeds wire, rope, or other material onto the core. The user controls the spindle speed and feeds the material through user hand, guiding it to control the tension and load pattern. These simple machines may be of a bench-top size or large stand-alone winder.
A coil winding machine is a machine for winding coil onto a spool, bobbin and many more. This coil winding machine is one of types of winding machine that available in industries today. The coil winders can be classified according to their speed levels and capacity. From multi speeded machines to medium, large and extra-large machines, these machines come in various types and categories, performing a range function. The common applications for a coil winding machine are to wind coils for transformer, inductors, motor and chokes. Coil winding machine design is dictated by a coil’s complexity, material tension limitations, machine versatilities, and automation / operator intervention, production volume and budgetary considerations [3]. Complete types of winding machine ideal for educational institutes, small and medium enterprise.
To complete a coil using manual coil winding machine will be inconvenience and waste of time. Furthermore, to have a good quality of automatic coil winding machine requires expensive tools and not user-friendly. Therefore, fabrication of coil winding machine will be done in this project which is controlled by two stepper motor using Arduino . This machine is inexpensive, easy to operate and build in a small-scale size. This project also can be used for training students in winding of small transformers & relay coils.
Basically these projects are listing three main objectives. The objectives are a guideline in order to complete this project. This project is conducted to achieve the following objectives:
Project scope is the part of project planning that involves determining and documenting a list of specific project goals, deliverables, tasks, costs and deadlines. In this project, the scope of the project is including a design and fabrication a small-scale coil winding machine at a lower cost. In this project, the coil winding machine size will be only in desktop size. All the programming and coding project will be using Arduino program to control two stepper motor motion. Some of the coils winding machine components are available at the faculty laboratory such as stepper motor, aluminium plate, and lead screw. Certain component such as round bobbin, guide pulley and motor coupling is fabricated using rapid prototyping machine.

CONSTRUCTION OF DUAL POT CHARCOAL STOVE
1.0 INTRODUCTION
One of the earliest sources of energy utilized by man was his own muscle. Food, water and other loads were borne by the arm, head, shoulder or back. Latter, animals such as dogs, donkeys, oxen and mules, etc were used as beasts of burden. Next to that was the discovery of fire, probably obtained by striking rocks together. The fire was used to cook food, keep warm, clear bush, preserve farm produce, harden pottery for bowls and produce tools from metals. Subsequently, other sources of energy such as solar energy, wind energy, electrical energy, nuclear energy and fossil fuels were discovered (Sutkhame, 1990 ).
The energy available to us can be divided into two main groups based on their sources. These are renewable and non-renewable sources. Renewable energy is obtained from animals and plants in the form of food, wood, and alcohol. These can be replaced when more is needed and are in the form of solar energy, wind energy, tidal or geothermal energy. Non renewable energy belongs to that group of energy that cannot be replaced once utilized. Examples are coal, oil and natural gas. These are known as fossils (Wikipedia, 2006).
The energy at man’s disposal is limited in supply. It is now an indisputable fact that our energy consumption habit which has been with us for many years cannot be treated with levity as our fossil fuel resources are being depleted at a fast rate. This consumption pattern has sky-rocketed the cost of conventional sources of energy with its observable side effects on our industries, domestic lives, agricultural production and commerce.
It is a well-known fact that more than half of the people in third world countries depend heavily on bio-fuels such as charcoal, fuel wood, crop residues and dung to meet their energy requirement for cooking. Going by the persistent low level of poverty and under-developments in these countries, it is unlikely that a major transformation to the use of petroleum fuels and electricity would be effected in the near future.
Due to poor storage facilities and inefficient transportation system, much of farmers’ produce are wasted after harvest even in the face of bumper harvests. In view of the Nigerian government’s recent “Cassava for Export Programme”, it is hoped that production of cassava will witness a boom and that calls for prudent handling of the fruits of the programme for it to yield the expected results.
Garri frying is a means of processing and preserving cassava. First the cassava tuber is harvested, peeled, washed and grated using a cassava grating machine. The grated cassava is then stored in a sack or other containers that will allow the fluid to drain for days depending on the quality of the garri to be produced. Sometimes a screw jack is employed to facilitate the squeezing of the sack containing the grated cassava. In the rural areas, the sacks containing the grated cassava are placed on logs of wood or stones and heavier logs of wood or stones are placed on them. Around the third day, the dried and fermented cassava is brought out of the sacks, sieved and dried in a frying pan.
The use of fuel wood has a tendency to aggravate the current state of deforestation. In the attempt to combat deforestation which leads to loss of forest cover and environmental degradation, many programmes have been put in place to conserve the supply and production of fuel-wood. Such measures include planting of fast growing trees, better land management and fuel importation. These programmes have not produced the anticipated magic.
The United Nations Food and Agricultural Organization (UNFAO) cited four causes of global deforestation which are: Shifting agriculture, opening pasture land to grow beef for export, commercial timber operation including timber access roads and uncontrolled bush burning. (Baldwin,1987). The foregoing shows that the use of charcoal for cooking is not a primary cause of deforestation on the global scale. Undoubtedly, the effect may become significant in urban areas and in arid regions where demand for fuel wood is high and the biomass
productivity of the land is small.
A restrained use of charcoal as fuel is a way of limiting energy losses due to the utilization of fuel woods. The petroleum fuels are nonrenewable and scarce in supply. Prudent domestic use of charcoal as fuel helps in making more petroleum fuels available for industrial and heavy duty purposes.
A stove can be defined as a heat-producing device. The word describes an appliance employed either for cooking or for generating warmth. In British English, however, the term cooker is normally used for cooking appliance and stoves for wood- or coal-burning units in roomheating devices. According to Wikipedia (2006), another American English word for a cooking stove is range.
There are many kinds of stoves. A kitchen stove is used to cook food, and refers to a device that has both burners on the top (also known as the cook top or range or, in British English, the hob) and, often, an oven. A cook top just has burners on the top and is usually installed into a counter top as shown in fig. 1.1.
Fig. 1.1 Glass-Ceramic cook-top
(Source: Stove-Wikipedia, the free encyclopedia)
A drop-in range has both burners on the top and an oven and hangs from a cutout in the counter top (that is, it cannot be installed freestanding in its own). In industrial usage, stove may refer to the place where fuel is burnt before the heat is fed to a large heat consumer such as an open hearth furnace.
A stove generates heat by one or more of the following means: A) Burning of natural gas, liquefied gases (e.g. Propane, butane), heating oil, bio-fuel (such as wood, coal, corn) or synthetic heating
pellets.
B) Electrically, by either electrical resistance (by way of a heating element) or induction (Wikipedia, 2006).

CARDIAC MONITOR
CHAPTER ONE
INTRODUCTION
1.1 Background of the study
The human heart pumps blood by the contraction and relaxation of the heart. Specifically, a small group of specialized muscle cells located in the upper right-hand corner of the right atrium (upper part of the heart) called sinoatrial (SA) node. Cells in the SA node generate their electrical signals more frequently than cells elsewhere in the heart. On the other hand, the ventricle which is the lower part of the heart pumps blood with much more force because of the thick muscle which it’s walls are composed of. Both the atrium and the ventricle perform their operations with the help of cells. These atrium cells in the cause of discharging their duties generate electrical signals which is passed through the help of some connected tissues partitioned by a small bridge of muscle called the atrio-ventricular conduction system down to the ventricle. The delay (lag time) between the signals reaching the ventricle is about two-tenth of a second. This delay allows time for the blood in the artria to empty into the ventricle before the ventricle begins contracting.
It is therefore paramount to note that the atrium and the ventricle do not pump blood simultaneously but take turns to do so. The activities of cells in the heart can be monitored by a heartbeat monitor called an Electrocardiogram (ECG or EKG). Electrocardiogram is derived from the Greek word “electro” for “electric”; “kardio” for “heart” and “graph” for “to write”) and the German word “electrocardiogram”. An ECG machine is used to detect and record electrical activity for diagnostic purposes. An ECG records the heart’s own electrical impulses to create an electrocardiograph, a reading that helps physicians learn more about the heart. It is important to note that the ECG is not a form of treatment but allows physicians diagnose heart diseases by taking a close look at the heart and its activities.
An electrocardiogram can:
i) Evaluate damaged and diseased tissue or other physical irregularities.
ii) Monitor any surgical repairs, pacemakers, or effects of drugs used to treat existing heart conditions.
iii) Determine whether the heart is performing normally or suffering from abnormalities (extra or skipped heartbeats cardiac arrhythmia).
iv) Indicate acute or previous damage to heart muscle (heart attack).
v) Be used for detecting potassium, calcium, magnesium and other electrolyte disturbances.
vi) Allow the detection of conduction abnormalities (heart block). vii) Suggest non-cardiac disease (pulmonary embolism).
The ECG records electrical activity by the aid of electrodes that are connected at strategic points on the body of the patient. These strategic placements which give the readings are recorded in pairs and these pairs are called leads. There are 3 types of leads which are 3-lead, 6-lead and 12-lead.
Each lead views the heart from a different angle. 3 and 6-lead ECGs, record limited heart activity, and are primarily used to monitor a patient’s heart during surgery, and can be used to diagnose early heart conditions. 12-lead machines look at the heart from twelve different angles and provide the type of readings necessary to diagnose and monitor patients with advanced heart conditions [4].
In a 12-lead ECG, six electrodes are attached to the skin on the chest around the heart. Four more electrodes are added, one on each arm and leg. The ten electrodes combine in twelve different ways to read twelve different angles on the heart.
When the heart depolarizes which occurs when the heart muscle which is negative at rest moves closer to a neutral charge with each heartbeat, the electrodes sense the tiny electrical impulses on the skin that are created as a result. The impulses travel back to the machine where they are interpreted and printed on a graph.
A healthy heart will print out an orderly wave of progression with each heartbeat, while a heart with diseased or damaged tissue will show certain irregularities in the heart’s rhythm, size, or position.
1.2 The normal ECG
A typical ECG tracing of a normal heartbeat consists of a P wave, a QRS complex and a T wave.
Axis: The axis is the general direction of the electrical impulse through the heart. It is usually directed to the bottom left.
P wave: The P wave is the electrical signature of the current that causes atrial (top chamber of the heart) contraction. Both the left and right atria contract simultaneously.
Fig. 1: Drawing of the EKG, with Labels of Intervals; P=P Wave, PR=PR Segment, QRS=QRS Complex, QT=QT Interval, ST=ST Segment, T=T Wave [5].
QRS: The QRS complex corresponds to the current that causes contraction of the left and right ventricles, causing a greater
ECG deflection due to more muscle mass.
The Q wave, when present, represents the small horizontal (left to right) current as the action potential travels through the inter-ventricular (lower chamber of the heart) septum.
The R and S waves indicate contraction of the myocardium (the thickest muscular wall of the heart around the ventricle where the pressure is greatest).
T wave: The T wave represents the repolarization of the ventricles, which is when the heart muscles go back to their negative state at rest after a heartbeat. The QRS complex usually obscures the atrial repolarization wave so that it is not usually seen. In most leads, the T wave is positive. Negative T waves can be signs of diseases; however an inverted T wave is common amongst black people.
The ST segment connects the QRS complex and the T wave.
An ECG is not usually performed as a preventative measure that is prior to any symptoms of possible heart conditions, it is only utilized to diagnose or rule out the presence of diseases, disorders, and other irregularities. ECG machines are often found in general practice clinics, as well as in ambulances, emergency rooms, hospitals, and cardiology centers [5]. Strong indications have emerged that people in under-developed countries are now at great risk of developing cardiovascular (heart) diseases which currently accounts for one-third of all deaths worldwide. Cardiovascular disease (CVD) is an umbrella term that refers to any of a number of diseases affecting the heart and blood vessels [7]. Electrocardiographs (results of ECG analysis) are usually complex and can only be interpreted by medical practitioners. This leaves the patients in the dark regarding the meaning of their ECG results. Also, most ECG machines print out the result in a sinusoidal wave form on a special tracing paper which makes subsequent accessibility rather tedious and traditional.
Consequently, the need for a device that addresses this issue is needed hence the birth of this project. The aim of this project is to provide the average person suffering from a heart condition with a portable device that can be used to monitor the heart, with results that are easily understandable to the patient and a form of storage for perusal later and analysis by medical personnel. Objectives of this project are to reduce the size of the heartbeat monitoring device currently available and making it more portable, furthermore, interpreting results to an extent and making it easily understood by non-medical personnel (layman), also to provide storage for heartbeat readings on the device which when connected to a computer system, can be analyzed by a doctor or printed for documentation.
