Abstract: Controlling and reconfiguring a display system that includes at least two screens that are installed in a cockpit of an aircraft in case of a failure of one of the screens. For example, a control unit of the display system may detect occurrence of a screen failure. In response to detecting the screen failure, the control unit may determine whether a critical flight relevant information has not been displayed on an operational screen during a predetermined period of time, and in response to determining that the critical flight relevant information has not been displayed on the operational screen during the predetermined period of time, command display of a message on the operational screen that suggests displaying the critical flight relevant information on the operational screen.

Abstract: The present invention relates to a method for localizing a sound source, in particular, a human speaker, comprising detecting sound generated by the sound source by means of a microphone array comprising more than two microphones and obtaining microphone signals, one for each of the microphones, selecting from the microphone signals a pair of microphone signals for a predetermined frequency range based on the distance of the microphones to each other and estimating the angle of the inci-dence of the sound on the microphone array based on the selected pair of micro-phone signals.

Abstract: A method of locating a sound source based on sound received at an array of microphones comprises the steps of determining a correlation function of signals provided by microphones of the array and establishing a direction in which the sound source is located based on at least one eigenvector of a matrix having matrix elements which are determined based on the correlation function. The correlation function has first and second frequency components associated with a first and second frequency band, respectively. The first frequency component is determined based on signals from microphones having a first distance, and the second frequency component is determined based on signals from microphones having a second distance different from the first distance.
