The aim of this work is to design and simulate low cost, portable efficient solar power inverter for standalone applications using MATLAB SIMULINK and MSP430 Micro controller. The designed expected output is 300 W, 230 V pure sine wave signal. The incremental conductance based Maximum Power Point Technique (MPPT) algorithm has been implemented using synchronous buck converter at the first stage. Since this project is designed for standalone applications, lead acid battery is selected, which has maximum charge storage capacity of 100 Ampere-Hour and charge/discharge rating of 10 i.e. 100 Ah and C/10, 12 V Lead Acid). Half bridge dc-dc converter is designed to boost the battery voltage from 14.5 V to 400 V DC. The final stage of the project is single phase full bridge inverter which produces the distorted quasi sine wave signal as output, which is later filtered to remove unwanted harmonics using designed LC low pass filter. Since this project is designed for low power applications, MOSFET is used as the switch in all the power circuit stages. The control strategy here is designed and accomplished by employing MSP-430F5132 micro controller which is user friendly and cost effective solution.

Banks and ATMs often rely on alpha-numeric passwords and biometric systems for authentication and secure access. Yet, a large number of cases on the misuse of accounts by miscreants continue to be reported. In this paper, we propose a novel security system based on Brain-Computer Interfaces that have the potential of providing higher security when compared to the above two methods. This system utilizes the Steady State Visually Evoked Potentials (SSVEP) generated by flickering visual stimuli for keying in the passwords. Both the Analog Front End and Digital Filtering & Analysis have been designed and implemented successfully. The Analog Front End includes a Pre-Amplification stage comprising of Instrumentation Amplifier, a Butter worth Filter and an Isolation Amplifier. The Digital Filtering and Analysis have been carried out using the ADS1298ECGFE-PDK and the computer. The simulation and individual module tests have shown promising results. Our final aim is that the integrated modules will provide enhanced security for password authentication.

In today's fast moving life, with everyone involved in the busy schedule, least attention is given towards one's own personal health. The health condition does not come to the notice until it goes alarming. By that time, they are vulnerable to serous risks. So it is advisable to continuously monitor one's own health so that preventing that serious condition is better than treating it. But continuous monitoring is not that feasible as visits to the clinic and getting tested consumes a lot of their working time. Only if the continuous monitoring could be done at ease, things will get a lot better. So, considering all these factors, the idea of monitoring at home could be offered in hand. This device incorporates electrical circuits that continuously measure the vital body parameters like the heart rate, temperature and the oxygen content in blood and also the concerned person is alerted if the condition goes abnormal.

Though various methods for controlling the robot have evolved over the last few years, an easy solution for this problem can be obtained by using human gestures as a mode of control for the robot. Gestures are the most significant means of interaction among humans, therefore the most intuitive solution for problem of controlling the robot lies in imitation, where the user adopts the role of a master and his/her actions are replicated by the robot, slave. Our mobile robot (slave) has two arms that can mimic the actions of human (master). The navigation is controlled using a joystick and the arm is controlled by the human actions.

Hostage crisis has become a common act by terrorists. Recent siege in Algeria has shook the world and the death toll still remains uncertain. Algerian Prime Minister, Abdelmalek Sellal, said 37 foreign nationals from eight countries and one Algerian died in the siege with five more people unaccounted for. Soldiers need to act spontaneously and contain the situation. They need to have a rough picture about the situation. RC controlled planes move fast and cannot go inside the buildings without being noticed. And also during battles on hilly terrains, spying becomes a difficult task and few examples mentioned above will not be able to do the task. Anything that helps soldiers survive and do their jobs better is certainly welcome. An autonomous robotic vehicle is an excellent choice as it meets the requirements. The vehicle should be able to spy in areas where human access is restricted and also it should not topple when spying on rough terrain and could be controlled from anywhere without range restrictions. In future there might be a time when all the human soldiers are replaced with robots.

User interfaces are important from the view point of ergonomics and user-friendliness. In this paper, we describe a user interface for a music player that can be used by both normal users as well as those who may be visually challenged. We explain how a simple "search" option can be added to enhance the listening experience without significant addition to the hardware resources. Our solution is based on the low-cost "launchpad" learning kit for the MSP430 micro controller from Texas Instruments and the associated capacitive sense booster pack for creating a user-interface. The audio booster pack (ABP) for the MSP430 launchpad was used as the music player.

Security is an integral part of our life, be it personal or providing it for our belongings. Constant technological advancements have been made in the field of developing security systems over the past few years. 'Radio frequency identification' (RFID) and 'Global system for mobile communication' (GSM) are a few fields in which security systems have propelled to new heights. RFID has been used widely for database management in places like malls and office areas. GSM is also used as a medium of interaction between the customer and back end devices in various fields. Our project is the first of its kind which brings together these popularly used systems in developing a three level security system. To give a complete overview of our project, the individual needs to have the pre-defined card, an RFID tag and a mobile phone whose contact number is given beforehand. Thus there are three levels of security for the secured place.

In this work, compact maximum power point tracking method of solar photo voltaic (PV) systems using analog ICs is presented. The analog circuit realizes the maximum power point tracking (MPPT) algorithm which exploits the non-linear characteristics of PV array. This algorithm tracks the maximum power of the solar PV array and maintains the same irrespective of the intensity and the fluctuations in the solar radiation, thus improving the efficiency of the PV system. To implement the proposed algorithm, TI components LM311, LM318 and SN7474 are used. In this work, the simulation of the proposed system has been simulated using Pspice at different operating conditions and results are presented with hardware implementation.

The project aims at developing a prototype boat that is capable of autonomously sailing and navigating its way through obstacles present around it. Apart from moving on a pre defined path the boat can intelligently avoid obstacles in the path through its ability of decision making using fuzzy logic. Calculations of fuzzy logic as well as deciding inputs for the path direction to be sent to the micro controller are done at the MATLAB workstation. The electronic system designed for the boat has excellent scalability and can be used for larger ships as well, but with some modifications. The project also includes the in house fabrication of the BLDC motor controller and the wireless communication board using various TI chips. The system developed is complete in terms of the hardware and software required for making a ship autonomous.

This project focuses on combining cognitive cues with the conventional physiological cues to have an improved approach for detecting stress. Current stress detection techniques rely on the measurement of certain physiological parameters based on which they determine stress. However, these techniques are not completely reliable because of the effect of other phenomenon on the physiological parameters. In this paper, an alternative method is proposed for the same purpose which involves the extraction of various cognitive features along with the traditional physiological data and processing it through neural networks aiming to make the results more accurate than existing system.
