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.

Low-cost dynamometers - A grip measurement and logging solution
(2013) Hasandka, A.; Ghosh, A.; Shetty, P.K.; Kini, R.
The aim of the project is to develop a grip measurement and data logging product which can be used as an exercise ball for patients who have undergone orthopedic surgery and as a recovery quantification tool for the doctor treating patients with the same condition. It provides the doctor with a measure of how effective the surgery has been and how well the patient has been recovering. and allows the doctor to quantify certain each force. The device logs the pressure applied on the ball for a period of time as a part of the recovering exercise and also has an attachment to measure the grip pressure between adjacent fingers and the thumb and other fingertips. The doctor has an interface on the other side on a computer that shows the logged data and allows the device to be put in various different modes to measure the different forces. It stores the parameters after every examination. � 2013 IEEE.
