    Low cost black box for cars
    (IEEE Computer Society, 2013) Patil, C.; Marathe, Y.; Amoghimath, K.; Sumam David, S.
    Automotive electronics plays a significant role in the automobile industry and provides luxurious features and more importantly addresses the safety and security concerns. The work presented in this paper aims at providing a cost effective solution to the design and development of an event data recorder which has been basically adopted from the aviation sector considering the need and the correlated benefits. The paper presents an integrated design of the black box with the basic features of the data recorder which could be very useful for domestic vehicles and at the same time it also hosts several additional features that could assist in mitigating the number of accidents, or at bare minimum, will serve as an analysis tool to prevent future accidents by analyzing the previous accidents. The black box also provides automatic accident notification system which helps in informing the nearest hospital and the traffic authority by providing not only the coordinates of the accident but also the exact physical address for immediate medical attention which can save numerous lives every day. The black box also hosts several other features like CAN compatibility, attractive user console and advanced web tracking anytime and from anywhere. Thus the overall cost is highly optimized by integrating such multiple features. © 2013 IEEE.

    Implementation and characterization of a numerical distance relay using a relay test-bench on RTAI-Linux platform
    (2013) Padmasali, A.; Amoghimath, K.; Hazarika, P.P.; Shetty, P.K.; Shubhanga, K.N.
    This paper deals with the implementation, evaluation and characterization of a numerical distance relay using a laboratory relay test-bench implemented on real-time application interface (RTAI)-Linux platform. The numerical distance relay has been realized on RTAI-Linux platform based on the full-cycle recursive discrete Fourier series algorithm. This relay provides a selectable relay characteristic such as Mho or Quadrilateral or Elliptical characteristic. The relay test-bench not only can be used to obtain steady-state relay characteristics, but also facilitates to generate any fault signals to perform dynamic testing of the relays. In this paper, Mho and Quadrilateral type numerical relay characteristics have been chosen for demonstration. It is found that such an experimental setup provides a hardware-in-the-loop facility in the lab environment to enhance the understanding about protective systems and thereby augmenting the classroom learning. © 2013 IEEE.
