Artificial retinas have been desired to recover the sight sense for sight handicapped people. Recently, artificial retinas using external cameras, stimulus electrodes, and three dimensional large scale integrations (LSIs) have been actively developed for patients suffering from retinitis pigmentosa and age related muscular degeneration. So in this seminar, we will discuss about the possibilities of artificial retina using thin film transistors (TFTs), which can be fabricated on transparent and flexible substrates. Electronic photo devices and circuits are integrated on the artificial retina, which is implanted on the inside surface of the living retina at the back part of the human eyeballs. In addition wireless power supply is used to drive the object. This helps to eliminate the connection wires and to realize complete artificial internal organs to improve the quality of life.

In this ECE seminar topic, we propose a new non-volatile FPGA circuit based on Spin-RAM technology (Spin Transfer Torque Magnetisation Switching RAM), new generation of MRAM (Magnetic RAM). This Spin-RAM based FPGA circuit could process securely the information in low power dissipation and high speed; meanwhile all the data processed are stored permanently in the distributed Spin-RAM memory. In this non-volatile FPGA design, MTJs (Magnetic Tunnel Junction) are used as storage elements.

Swarm intelligence is the emergent collective intelligence of groups of simple autonomous agents. Here, an autonomous agent is a subsystem that interacts with its environment, which probably consists of other agents, but acts relatively independently from all other agents. The autonomous agent does not follow commands from a leader, or some global plan.

This ECE Seminar Topic on Adaptive Active Array Phased Multifunction Radars, discuss about features and implementation of Radars. Over the years radar systems have been changing on account of the requirements caused by Increase in the number of wanted and unwanted targets, reduction in target size either due to physical size reduction due to the adoption of stealth measures, the need to detect unwanted targets in even more sever levels of clutter and at longer ranges, the need to adapt to a greater number of and more sophisticated types of electronic counter measures. Radar designers addressed these needs by either designing radars to full fill a specific role, or by providing user selectable roles within a single radar. This process culminated in the fully adaptive radar, which can automatically react to the operational environment to optimize performance.

Blue Eyes system provides technical means for monitoring and recording the operator’s basic physiological parameters. The most important parameter is saccadic activity1, which enables the system to monitor the status of the operator’s visual attention along with head acceleration, which accompanies large displacement of the visual axis (saccades larger than 15 degrees). Complex industrial environment can create a danger of exposing the operator to toxic substances, which can affect his cardiac, circulatory and pulmonary systems. Thus, on the grounds of plethysmographic signal taken from the forehead skin surface, the system computes heart beat rate and blood oxygenation.

Driverless city vehicles for civilian,non-military applications are not likely to gain a wide wide public acceptance unless they prove to be safer than conventional human-driven vehicles. Therefore, road safety is the highest objective in the effort of developing such vehicles, as is the case for any transportation system. The correctness of driverless vehicles’s control software is one of the crucial requirements to ensure safety. As a hard real-time (mission-critical) system, correctness refers not only to functional correctness, but also includes temporal correctness i.e. the control software needs to produce correct results within specified time intervals. In order to achieve this objective, the design and implementation of the control software for driverless vehicles needs to be focused on enabling the proof of correctness through verification and validation procedures.

In the past few years, the cost of access to public wireless data networks has been dropping while the capabilities of these networks continue to increase. Machine-to-machine (M2M)communications is a new technology that leverages these networks to bring smart services to a much wider audience. Differentfrom the traditional human to human (H2H)communications for which the current wireless networks are designed and optimized, M2M communications is seen as a form of datacommunications between entities that do not necessarilyneed any form of human intervention. It is different from current communication models in the sense that it involves new or different market scenarios, low cost and low effort, a potentially very large number of communicating terminals, and small and infrequent traffic transmission per terminal. The industry has already been working on providing M2M communications and smart services offerings across a wide variety of market segments, including healthcare, manufacturing, utilities, distribution, and consumer products.

This presentation on ECE Seminar topic, Metamorphic Robots gives a detailed info about these special type of robots which can change their shape without human intervention. Robots used indoors are constrained by their programming and geometry. For those used outside, their mission and topography are unpredictable. PolyBot (Xerox Palo Alto Research Centre) and Conro Robots (Information Sciences Institute, University of South California) are examples.

In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating current of radio frequency,Carbon nanotubes are expected to help in the miniaturization of electronic circuits. They are expected to bridge contact between macroscopic and nanoworld. CNTs working as antennas is a field still in its infancy. They are predicted to work efficiently in the high frequency range. Enhancement of radiation efficiency at tera hertz range was achieved using a bundle of single walled carbon nanotube (SWCNT) instead of a single SWCNT. However still a lower cut off frequency limit (100GHz) occurs. The structure proposed in the paper was used to enhance the radiation efficiency and radiation resistance at the lower part of tera hertz band or sub tera hertz band. The nanotube antenna differs from an ordinary antenna due to to its high kinetic inductance, characteristic impedance, etc.
