Implementation of Oriented Filters for Arc Detection. [PDF]

open access: yesProcedings of the British Machine Vision Conference 1995, 1995
This paper is concerned with the implementation of oriented Gaussiantype filters with several possible decomposition schemes, including the steerable approach and the wavelet transform. A novel spatial decomposition scheme is introduced, in which the filters are projected onto a set of Gaussian basis functions which are not dependent on the orientation

Detection of electric arcs in large batteries

open access: yes2013 World Electric Vehicle Symposium and Exhibition (EVS27), 2013
This paper addresses the precocious detection of electric arcs in an electric vehicle battery generated by a connector fault. The detection principle is based on the acoustic emission of the arc. First, the identification of the electric arc acoustic signature as well as disturbances in the environment of detection has been realized.
