This research proposed a web-based monitoring system that can help to view heart beat rate of a person while tracking his locations in real time. By using Heart Pulse Sensor and GPS Module connected to arduino microcontroller, the system collects data and transmits them to a remote server. We use GSM/GPRS Module as the network unity to send collected data over Internet. A supervisor through a web page, monitors heart beat rate and view locations on Google Map. The system can help to resolve health emergencies. In this way, it simultaneously improves the quality of care through constant attention.

In this paper, a smart stick is intended and executed to aid blind persons so that they can walk independently without much difficulty. Firstly, pothole detection and avoidance system are implemented by setting the ultrasonic sensor at 30-degree angle on a suitable blind stick to sense if there is a hole or staircase in front of the blind at about 30 cm distance to avoid a person from falling and as a result may be producing many damages. Secondly, a moisture sensor is placed at the down of stick to measure the degree of water land soil moisture in forward-facing of the user and aware him as soon as that degree exceeds a measured level that may submerge the foot of him. Thirdly, knee above obstacle detection and avoidance system is implemented by using an additional ultrasonic sensor on the top of the stick to turn an alarm and vibration ON when there is a person, obstacle or wall at a distance of 50 cm in front to avoid an accident and thus helping the person to move independently. Fourthly, an ultrasonic sensor is placed down the stick at about 20 cm from the ground level to detect and avoid knee below obstacles and stairs at a distance of 70 cm in front of the user. Fifthly, a wireless remote consisting of RF modules (transmitter and receiver) is implemented, so if a person drops stick or forget it somewhere, he can press a switch of the remote consisting of transmitter part, and as a result alarm with vibrations will turn on, so the user can know the location of the stick. The stick is implemented practically using single wheel leg blinding cane, arduino microcontroller three ultrasonic sensors RF modules. Also, two buzzers and two vibration motor are used on the stick to fit on when any difficulties occur.

This paper outlines the methodology of designing and implementation of a solar powered system which can be used to make a human comfort zone during day time without using battery backup but with the use of Supercapacitors. Basically, major converter losses are reduced in this system. In acquiring a highly efficient power supply, the charge controller plays an important role. When a DC microgrid powers DC loads based on a renewable source such as a PV system;energy storage becomes mandatory due to fluctuating nature of the source. Localized DC-energy storage within DC-DC converters could address this requirement. A variation of supercapacitor assisted regulators could provide localized energy storage with low-noise and fast transient response [1]. 12 V LED lights will be powered from this system. LEDs can be powered directly via a supercapacitor bank from the regulated Photovoltaic energy. In the case of Inverter type Air Conditioner, in order to overcome converter losses, the DC Bus inside it should be accessed. Typically, DC Bus voltage inside the Variable Frequency Drive (VFD) is 1.414 times the supply voltage. Hence DC-DC Converters are used to power up the inside circuitry of the Inverter Air Conditioner from the solar panel. In order to optimize the energy usage and reduce electricity consumption, light dimming and air conditioning control systems were added to control the light intensity and switching of the air conditioner.

Close-in weapon systems (CIWS) are an essential, computer-controlled defensive measure available on modern warships. Due to their size and weight, however, CIWS are deployed only on warships with a displacement over 1000 tons. Smaller ships, such as patrol boats, still carry and use less accurate crew-controlled heavy machine guns. We propose a small, light-weight, and portable CIWS that can be easily installed onto smaller warships. The proposed CIWS incorporates automated target tracking to reduce errors that arise from manual operation. A prototype system, consisting of a stabilizing platform and a gun control unit, was designed and constructed for this research. The prototype incorporated sensors and microcontrollers to provide an automated target tracking capability. Two independent closed-loop controllers were implemented integrating inertial and vison-based sensors to provide automatic stabilization and tracking. A support structure for the prototype was fabricated using parts made with a three-dimensional printer. Through experimental measurement and simulations, performance of the prototype was evaluated and compared favorably with that of existing CIWS systems; however, during the course of this work, we found that several improvements would be required to make the proposed portable CIWS a viable solution. The work highlighted the need for an upgraded inertial sensor, motor gear assemblies that have much less backlash, and stronger supporting structure.

This paper presents theoretical analysis and experimental implementation of a classical controller with intelligent properties. The controller has constant parameters, but it performs as an intelligent controller. The controller design mimics the fuzzy logic controller in a classical form and combines the advantages of classical controllers and properties of intelligent controllers. The designed controller parameters force the controlled variable to behave such as a first order system with a desired time constant. DC motor practical system is used to demonstrate the effectiveness of the presented controller. Root locus and frequency response using Bode diagram are used to help the design of the controller parameters. Simulation and experimental results verify the high performance of the presented controller.

With the continued establishment of hacker-spaces and fab-labs hosted in academic libraries, there is an increase in the availability of resources for designing scientific instrumentation in the undergraduate curriculum. Many available designs, however, may be too complex to fabricate in teaching environments. Presented here is OMIS, the Open Millifluidic Inquiry System, which is a platform for performing small-scale chemical synthesis and analysis. OMIS consists of a 3D printed syringe pump, control hardware based upon the arduino microcontroller and 3D printed reaction vessels. The OMIS syringe pump utilizes a low-power stepper motor which simplifies the instrument construction and allows for power to be supplied from batteries or the USB port of a computer. The simple design of OMIS allows for the instrument to be fabricated in one day, including the time to 3D print components. The OMIS syringe pump is able to deliver fluids at rates between 60 and 300 mu L/min, depending on syringe size, with a reproducibility of 3%. Several applications of OMIS are presented, including a demonstration of laminar flow in a 3D printed millifluidic chip, implementation of a low-volume flow-cell cuvette insert and the synthesis of magnetite nanoparticles.

Pipe inspection robot are used to monitor, inspect and maintain inner pipe conditions. In this paper, a wall-press type platform is fabricated. It consists of three sections that is camera section, front driving module section and back driving module section with a total length of 542mm and maximum expansion diameter of 230mm. Wall-press type has the advantage to varies its maximum diameter. Camera section located in front of the robot to provide 180 degrees unobstructed vision of the inner pipe conditions. Two driving modules prevent robot from being obstruct by obstacles. arduino microcontroller is used to control the robot operation and GUI is used to operate it. Actuator used are DC micro metal geared motor, DC motor and micro servo motor. Overall. this robot is able to successfully climb a slope not more than 30degree. However, sensors need to be implemented to detect the maximum pipe diameter.
