File Wireless Technology and Convergence PPT PowerPoints that can be used to Seminar topics and Slide Projects. Wireless communications originated with the demonstration by Tesla in 1893, followed by the invention of wireless telegraph by Marconi in 1896. Advances in wireless communications have led to radio, television, mobile telephones, and communication satellites. Development of wireless networks: LAN, MAN, and WAN. Wireless applications span both local area and wide area for: voice-oriented services, and data-oriented services.

Cloud and Cloud Computing

Abstract :Here are chapter online PPT Material Presentation on Cloud and Cloud Computing. File Cloud and Cloud Computing PPT PowerPoints that can be used to Seminar topics and Slide Projects. Cloud is Demand resources or services over Internet scale and reliability of a data center. Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a serve over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the “cloud” that supports them. The architecture of cloud computing system. Characteristics of cloud computing are Virtual software, databases, Web servers, operating systems, storage and networking as virtual servers. And On demand, add and subtract processors, memory, network bandwidth, storage. Grid Computing & Cloud Computing. The problems are mostly the same. manage large facilities, define methods by which consumers discover, request and use resources provided by the central facilities, implement the often highly parallel computations that execute on those resources. Virtualization Grid is do not rely on virtualization as much as Clouds do, each individual organization maintain full control of their resources and Cloud is an indispensable ingredient for almost every Cloud.

BrainGate System

Abstract :Here are chapter online PPT Material Presentation on BrainGate System. File BrainGate System PPT PowerPoints that can be used to Seminar topics and Slide Projects. Definition BrainGate Neural Interface Device- a ‘brain-computer’ interface that uses internal neural signal sensor and external processors to convert neural signals into an output signal under the users own control. The sensor consists of a tiny chip (smaller than a baby aspirin) with one hundred electrode sensors each thinner than a hair that detect brain cell electrical activity. The electrode translates brain activity and sends the information to the computer in a format it can understand. BrainGate uses a sensor that is implanted onto the motor cortex of the brain. The device analyzes brain signals then interprets and translated them into cursor movements.

Introduction, IEEE 1451 family, 1451.3 Overview, Objectives of 1451.3, 1451.3 General Model, 1451.3 Terms, Data Types, Smart Transducer Functional Specification, Addresses, Operating States, Data Sets, Messages and Packets, Triggering Methods, TransducerChannel Type Descriptions, Commands, TEDS and Conclusion. The Smart Sensors Low-cost, networked smart sensors are developed for diverse industry’s needs. Interfacing the smart sensors to all of these control networks and supporting the wide variety of protocols require very significant efforts. A universally accepted transducer interface standard, the IEEE P1451 standard, is developed.IEEE 1451 is a family of proposed standards for “A Smart Transducer Interface for Sensors and Actuators”. Together these standards provide a single generic interface between a transducer and external network,independent of the network protocol in use. A sensor shall measure some physical parameter on demand and return digital data representing that parameter. On the receipt of a trigger the sensor shall start the collection and storing of a data set within the TBIM. A sensor, in the operating state, shall respond to a read command by returning the appropriate data set. The Standard has provided the beginning of a consistent set of tools to address the issue of displaying data in a standardized way. By providing a way for a set of base units to be incorporated into the transducer, the working group has standardized the way that the units are represented in the TEDS. A transducer that is built and calibrated per the standard should be able to plug into any system.
