Design of IOT enabled robust control of an artificial ventilator

To breathe, the human lungs use the reverse pressure generated by the diaphragm's contraction motion to suck in air. A ventilator uses a contradictory motion to inflate the lungs via a pumping motion. A ventilator mechanism must be capable of delivering between 10 and 30 breaths per minute, with the ability to adjust rising increments in sets of two. In addition, the ventilator must be able to adjust the amount of air pushed into the lungs with each breath. The last but not least option is to change the time duration for the inhalation to exhalation ratio. Emergency situations aside from that, the ventilator must be able to monitor the patient's blood oxygen level and exhaled lung pressure in order to avoid complications. To adjust the time duration for inhalation, an option command given in the IoT application. The entire system is driven by PIC controller to achieve desired results and to assist patients.

An Automatic Cash Detector for PID Controller Based Self-service Petrol Dispenser

In this paper, we propose a design and implementation of an automatic self-service petrol dispenser that receives payment from a customer in the form of cash, instead of e-money of or credit card as those in many similar machines existing in Indonesia. Hence, the system can facilitate a vast majority of potential customers who have no access to any form of e-money, credit card, or simply because of personal preference of using cash. The experimental results show that every component can communicate smoothly; thus, relevant parts in the system received information as intended. Furthermore, the system is capable of recognizing the value and authenticity of the cash inserted to the machine using the template matching technique with an accuracy level of 95,83%. As equally important, the amount of petrol which is pumped out-flowing to the customer's tank using a PIC controller with an accuracy level of 98.22%.

A NOVEL BIDIRECTIONAL QUASI Z SOURCE INVERTER FOR ELECTRIC VEHICLE APPLICATIONS

The fixed frequency sliding mode control method for this project is a single-phase grid-connected LCL filtered quasi-Z-source inverter (QZSI). In the proposed method, smoothing is applied to the function of the sliding surface, thereby eliminating jitter and achieving a fixed switching frequency.

The DC output of the battery is converted to AC using a DC AC inverter after withstanding or increasing demand. The inverter function must change the DC input voltage to the desired voltage and voltage as the asymmetric AC output voltage achieved through the control branches of Quasi by using simple boost control technology.

Experimental study on modified water injected four stroke petrol engine

The aim of the present study in “Water Injected four stroke petrol Engine” is to reduce the pollution and the consumption of the fuel. From the name we can get that there are two modifications made in the engine. The first modification is the installation of the water injector in the flanged GI pipe running between carburetor and engine and the second one is the introduction of the oxy hydrogen gas into the inlet manifold. Various research papers have proved that injection of the water directly into the engine will lead to the decrease in the emission of the oxides of nitrogen. The water is first pumped by using a water pump and then injected into the inlet manifold by using the petrol injector. The oxy hydrogen gas is obtained by the electrolysis of the water by using the neutral plates. The injection of the water into the engine is controlled by using the PIC controller board. The water is injected at certain timing which is controlled by using a relay. Both the injector and the pump is controlled by the circuit board. Power supply is given separately for water injection circuit and the oxy hydrogen set up. The emission tests that are done on this prototype as shown a reduction in the level of the pollutants emitted from the engine and also a slight increase in the performance of the engine is noticed.

Object Identification for Visually Impaired

Objectives: This paper is based on a device that helps blind people to identify a set of objects used in everyday routine thereby enabling them to work independently. Method/Analysis: A new portable camera based method to recognize indoor objects for helping blind people is introduced. A more improvised algorithm called as the Coarse Description Technique has been employed. The coarse description technique can be implemented in two ways: Euclidian distance measurement method and another method that relies on semantic similarity measure modeled by means of Gaussian process estimation. Findings: The techniques used currently perform the recognition task by limiting it to a single predefined class of objects. The proposed concept in this paper utilizes a completely different alternative scheme termed as coarse description. Its main objective is to expand the recognition task to multiple objects and keep the processing period under control at the same time. While the Euclidian distance measurement method evaluates every image based on a matrix created using details regarding the pixels of each image, the Gaussian process estimation method compares images using a number of image attributes. Novelty/Improvement: PIC controller used in the existing system is replaced by a Raspberry Pi board which provides a computation speed twice as fast as the former.

<b>Pulse Mask Controlled HFAC Resonant Converter for high efficiency Industrial Induction Heating with less harmonic distortion

This paper discusses about the fixed frequency pulse mask control based high frequency AC conversion circuit for industrial induction heating applications. Conventionally, for induction heating load, the output power control is achieved using the pulse with modulation based converters. The conventional converters do not guarantee the zero voltage switching condition required for the minimization of the switching losses. In this paper, pulse mask control scheme for the power control of induction heating load is proposed. This power control strategy allows the inverter to operate closer to the resonant frequency, to obtain zero voltage switching condition. The proposed high frequency AC power conversion circuit has lesser total harmonic distortion in the supply side. Modeling of the IH load, design of conversion circuit and principle of the control scheme and its implementation using low cost PIC controller are briefly discussed. Simulation results obtained using the Matlab environment are presented to illustrate the effectiveness of the pulse mask scheme. The obtained results indicate the reduction in losses, improvement in the output power and lesser harmonic distortion in the supply side by the proposed converter. The hardware results are in good agreement with the simulation results.
