ELETRONICS SEMINOR:
Organic light emitting diodes (OLED):
Seminar Description:The Smart NoteTaker is good and helpful for blinds that think and write freely. Another place, where our product can play an important role, is where two people talks on the phone. The subscribers are apart from each other while their talk, and they may want to use figures or texts to understand themselves better. It's also useful especially for instructors in presentations. The instructors may not want to present the lecture in front of the board. The drawn figure can be processed and directly sent to the server computer in the room. The server computer then can broadcast the drawn shape through network to all of the computers which are present in the room. By this way, the lectures are aimed to be more efficient and fun. This product will be simple but powerful. The product will be able to sense 3D shapes and motions that user tries to draw. The sensed information will be processed and transferred to the memory chip and then will be monitored on the display device. The drawn shape then can be broadcasted to the network or sent to a mobile device.
Universal Mobile Telecommunications System (UMTS)
Seminar Description:The Universal Mobile Telecommunications System (UMTS) is a third generation (3G) mobile communications system that provides a range of broadband services to the world of wireless and mobile communications. This chapter presents an overview of the UMTS architecture specified by the Third Generation Partnership Project (3GPP), focusing on the network elements relevant to the study presented here. The evolution towards an All-IP network, within the 3GPP, is occurring in several steps, known as releases [6, 7]. Earlier UMTS specifications, with a relatively strong retention of the current 2nd generation networks, were still switch centric. However, the introduction of a new IP platform, when fully specified, will provide the UMTS system with multiple wireless access options and full IP packet support.
Wireless Energy Transfer using Magnetic Resonance :
Seminar Description:In 1899, Nikola Tesla, who had devised a type of resonant transformer called the Tesla coil, achieved a major breakthrough in his work by transmitting 100 million volts of electric power wirelessly over a distance of 26 miles to light up a bank of 200 light bulbs and run one electric motor. Tesla claimed to have achieved 95% efficiency, but the technology had to be shelved because the effects of transmitting such high voltages in electric arcs would have been disastrous to humans and electrical equipment in the vicinity. This technology has been languishing in obscurity for a number of years, but the advent of portable devices such as mobiles, laptops, smartphones, MP3 players, etc warrants another look at the technology. We propose the use of a new technology, based on strongly coupled magnetic resonance. It consists of a transmitter, a current carrying copper coil, which acts as an electromagnetic resonator and a receiver, another copper coil of similar dimensions to which the device to be powered is attached. The transmitter emits a non-radiative magnetic field resonating at MHz frequencies, and the receiving unit resonates in that field. The resonant nature of the process ensures a strong interaction between the sending and receiving unit, while interaction with rest of the environment is weak.
DIGITAL JEWELERY:
Seminar Description:Mobile computing is beginning to break the chains that tie us to our desks, but many of today's mobile devices can still be a bit awkward to carry around. In the next age of computing, there will be an explosion of computer parts across our bodies, rather than across our desktops. Basically, jewelry adorns the body, and has very little practical purpose. However, researchers are looking to change the way we think about the beads and bobbles we wear. The combination of microcomputer devices and increasing computer power has allowed several companies to begin producing fashion jewelry with embedded intelligence i.e., Digital jewelry. Digital jewelry can best be defined as wireless, wearable computers that allow you to communicate by ways of e-mail, voicemail, and voice communication. This paper enlightens on how various computerized jewelry (like ear-rings, necklace, ring, bracelet, etc.,) will work with mobile embedded intelligence. It seems that everything we access today is under lock and key. Even the devices we use are protected by passwords. It can be frustrating trying to keep with all of the passwords and keys needed to access any door or computer program. This paper discusses about a new Java-based, computerized ring that will automatically unlock doors and log on to computers.
Paper Battery:
Seminar Description:A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotube s with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and supercapacitor , combining two components that are separate in traditional electronics . This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of electronics, medical devices and hybrid vehicles, allowing for radical new designs and medical technologies. Paper batteries may be folded, cut or otherwise shaped for different applications without any loss of integrity or efficiency . Cutting one in half halves its energy production. Stacking them multiplies power output. Early prototypes of the device are able to produce 2.5 volt s of electricity from a sample the size of a postage stamp.
STARFAST: a Wireless Wearable EEG Biometric System based on the ENOBIO Sensor :
Seminar Description:Starfast is a wearable, wireless biometry system based on the new ENOBIO 4- channel electrophysiology recording device developed at Star lab. Features extracted from electroencephalogram (EEG) and electrocardiogram (ECG) recordings have proven to be unique enough between subjects for biometric applications. We show here that biometry based on these recordings offers a novel way to robustly authenticate or identify subjects. In this paper, we present a rapid and unobtrusive authentication method that only uses 2 frontal electrodes and a wrist worn electrode referenced to another one placed at the ear lobe. Moreover, the system makes use of a multistage fusion architecture, which demonstrates to improved system performance. The performance analysis of the system presented in this paper stems from an experiment with 416 test trials, where an Equal Error Rate (EER) of 0% is obtained after the EEG and ECG modalities fusion and using a complex boundary decision. If a lineal boundary decision is used we obtain a True Acceptance Rate (TAR) of 97.9% and a False Acceptance Rate (FAR) of 0.82%. The obtained performance measures improve the results of similar systems presented in earlier work.
