<p class="p1">Testing of underwater system for defence application is carried out from submersible platform at specified depth. The underwater platform houses the article under test, equipment and instruments required to conduct the test and to control the platform. During development phase of defence systems, large numbers of sensors are mounted on the test article and data is collected to validate the design. Data acquisition system, video camera and high speed video cameras are positioned on the platform to record physical parameters and observe visually the performance of the article under evaluation. Since the data and video signals are parallely recorded on ship, the bandwidth demand for real-time data communication from underwater platform to control station is very high. The existing technology presently used for underwater communication has limitation of bandwidth and not suitable for defence application. This paper describes in detail the design and development of a re-deployable data communication link by laying a specially designed negatively buoyant fibre optic cable in high-sea from ship to underwater platform to provide higher bandwidth required for defence application. The link has been successfully used for sea state less than one during evaluation of underwater defence system. The availability of bandwidth from underwater platform to control system can be increased significantly by laying fibre optic cable in high sea. It also provides unlimited bandwidth for the above requirement.<span class="Apple-converted-space"> </span></p>

Picture Archiving And Communication

Using the JAVA language we have developed a Web-based picture archiving and communication system PACS which allows a remote hospital to access medical images. An asymmetric satellite data communication system ASDCS provided a receive-only link for data delivery and a conventional terrestrial link which could be the conventional telephone network allowed data transmission. The satellite communication link was 10- 30 times faster than the conventional terrestrial link. To increase image transmission speeds over the Internet connection, JPEG and wavelet compression methods were used. The resulting images were evaluated quantitatively by measuring the peak signal:noise ratio and qualitatively by radiologists. Compression ratios of 10:1 or less were deemed acceptable for diagnostic purposes. The system appears to be suitable for teleradiology and telemedicine.

We present rotational misalignment and bending effects on a hybrid system to transfer power and data wirelessly for an implantable device. The proposed system consists of a high-frequency coil (13.56 MHz) to transfer power and an ultra-high frequency antenna (905 MHz) for data communication. The system performance and the transmitted power were studied under two misalignment conditions: (1) receiver rotation around itself with reference to the transmitter, and (2) bending of the implanted receiver under three different radii. Implanted receiver was printed on a flexible Kapton substrate and placed inside a layered body tissue model at a 30 mm depth. It is shown that the inductive link is stable under rotational misalignment and three bending conditions, whereas the communication data link is suitable to be used if the rotation angle is less than 75° or larger than 150°. The results show that the resonance frequency varies by 1.6%, 11.05%, and 6.62% for the bending radii of 120 mm, 80 mm, and 40 mm, respectively. Moreover, transmission efficiency varies by 4.3% for the bending radius of 120 mm. Decreasing the bending radius has more effects on antenna transmission efficiency that may cause severe losses in the communication link.

At present day’s wireless sensor networks, obtain a lot consideration to researchers. Maximum number of sensor nodes are scattered that can communicate with all others. Reliable data communication and energy consumption are the mainly significant parameters that are required in wireless sensor networks. Many of MAC protocols have been planned to improve the efficiency more by enhancing the throughput and energy consumption. The majority of the presented medium access control protocols to only make available, reliable data delivery or energy efficiency does not offer together at the same time. In this research work the author proposes a novel approach based on Receiver Centric-MAC is implemented using NS2 simulator. Here, the author focuses on the following parametric measures like - energy consumption, reliability and bandwidth. RC-MAC provides high bandwidth without decreasing energy efficiency. The results show that 0.12% of less energy consumption, reliability improved by 20.86% and bandwidth increased by 27.32% of RC-MAC compared with MAC IEEE 802.11.

In this chapter, we report on the use of the TINI (Tiny InterNet Interface) microcontroller platform, DSTINIM400, as a cost effective solution to deploy feedback control laboratory experiments online. The DSTINIM400 has a built-in 10/100 Base-T Ethernet capability and provides 24 digital inputs/outputs. A TINI runtime environment, embedded in the DSTINIM400, allows developers to interact with the microcontroller like a network terminal where Java program code is downloaded and executed via the Ethernet communication protocol. The use of Java programming environment on the TINI microcontroller yields a simple interface to many Ethernet protocols allowing programmers to intuitively define a data communication link between the TINI microcontroller and a remote graphical user interface (GUI) control panel. We utilize the DSTINIM400 to interface with a variety of laboratory experiments, execute user-selectable control algorithms, and establish Internet data communication with remote GUI control panels. We provide remote GUI control panels in the form of Java applet webpages, where sensor data is presented to remote users as a plot GUI component and control system structure and parameter values are presented as binary switches, sliders, and text boxes. Finally, safety protocols are evaluated and implemented to safeguard online laboratory experiments.
