Brain Machine Interface Seminar Topic

Introduction to brain machine interface:

In this paper, we will see how the brain machine interface is made and how the capabilities of the human being can be extended. We will about the advantages of using brain machine interface and the problems faced by this.

The capabilities of a human being are limited and a capability of a machine is higher but it cannot think of its own. Research is going on for making a machine to interface with the brain by which the capabilities of a human being are far extended.

Brief on brain machine interface:

The human brain takes decisions based on the impulses generated in the body and in a human body we find millions of neurons which generate impulses. So a chip is designed and it is placed in the human body and it is made to integrate with the nerve fibers. The chip is interfaced with a remote computer outside.

The chip senses the impulses generated in the body and performs the tasks with the help of the remote computer or the server located outside. The chip is designed by using nano technology and it is constructed in such a way that it can generate the power required for it through heat generated in the body or by the flow of blood circulation.

The chip has successfully placed a body of professor in a university and he could control the appliances without lifting his hand from a given range.

Proposed Brain Systems in Future:

The proposed brain machine interface chip can be very helpful to make the organisms to work properly for the paralyzed patients. By using brain machine interface the human capabilities gets increased a lot and many technological advancements can be made.

But due to this there may differentiation in between the persons who are using the interface chips and the normal human being. All details about this system explained in the given ppt presentation.

Smart Antenna Technology for Mobile Communication Systems

Introduction:

In mobile communication networks we find antennas which work in Omni directional pattern. Due to Omni direction antennas the signals gets transmitted in all the directions but due to this we cannot find the same signal strength in all the directions.

As all the antennas are Omni directional we find interference of the signals due to which the signal disturbances occur. So as to transmit the signal in a particular direction we need to use smart antennas in this Smart Antenna Technology for Mobile Communication Systems paper we will see how smart antennas work and the principle behind the transmission of the signals.

Brief on smart antennas:

By using this antenna we can emit the beam of the spectrum to the particular user only and it allows us to separate the users by space division multiple access technique.

By using switching lobes which consists of basic switching functions by which we can separate the directive paths of the projected beams of the directive antennas. In order to use the received signal from the user we need to use dynamically phased arrays.

To decide the antenna pattern in up link and down link directions the array elements are calculated based on the complex weights which are done by signal processing unit.

Conclusions:

To meet the growing traffic needs we need to use smart antennas by which the potentiality of the network increases. By introducing the smart antennas we can increase the capacity of the time division multiple access systems by three times and we can find five times increase in code division multiple access technique.

The major drawbacks of smart antennas are the increase in transceiver complexity and difficulty in radio management. By using smart antennas we can use the radiation pattern in a specified direction by which we can improve the quality of communication.

In this Wireless Power Transmission for Solar Power Satellites Seminar paper we will look into solar power sources for power generation and transmitting them in wireless pattern.

Space satellites need power and by using this technology we can transmit power wirelessly in the form of microwaves.

Wireless Power Transmission for Solar Power Satellites Seminar

Wireless power transmission pattern:

We use solar panels which consist of photo voltaic cells which trap the power and we transmit the stored energy in the form of microwaves. Previously there is no technology to convert microwaves to electricity but in the present days due to advancements it is possible. To convert the power in to microwaves we need to use a magnetron and it gets transmitted to the free space.

To receive the micro wave power we need a receiver which is called rectenna which consists of two dipoles which absorbs the transmitted power and the power received in this pattern has an output efficiency of 85 percent.

Technology Requirements:

By using this technology we can meet the energy requirements and the solar technology does not cause pollution. By using wireless power transmission we can transmit power to the space satellites and other devices by using microwave receivers. By using this technology we can transmit power to the required sources without the need of wires.

At present the wireless power transmission technology is still in a developing stage and will come into usage in the future.

Optical Performance of the Grating Light Valve Technology Seminar

Introduction to grating light value technology:

The grating light value technology is used to enhance the performance capabilities in optical systems. These are mainly used in projection display systems to improve the quality of the picture. In this paper we will be discussing about the linear array module of 1080 GLV pixels. The GLV pixels cab is fabricated in such a way by which switching rates can be obtained at the speed of 20 nano seconds. In this Optical Performance of the Grating Light Valve Technology Seminar paper we will discuss grating light value pixel implementation and its working model.

Brief on grating value technology:

These produce an electro-mechanical response which can be tuned and this used for increasing the performance in various applications. The grating light value pixels are in an addressable diffraction grating form which consists of moving parts made on a silicon chip.

In each grating light value pixel we find dual supported parallel ribbons which are made of silicon nitride and they are coated with reflected aluminum as a top layer. When all the pixels form a flat reflective plane then they get turn off. The GLV driver chips receive the data in a linear rate which is similar in function like LCD driver chips.

Conclusions:

The linear grating light value has the capability to support 3 value color, frame sequential and line sequential systems. By employing this technology an unparalleled on screen response is achieved which has 99% uniformity, high contrast and greater corner to corner efficiency.

The efficiency of the grating light value pixels mainly depends on the aperture ratio, diffraction efficiency and reflectivity of the aluminum surface.

This Paper Includes:

  • GLV Device Fundamentals
  • The Linear GLV Array
  • Optical System Architecture
  • Image Quality and System Performance
