The method includes the steps of determining an eye gaze direction relative to a given frame of reference for at least one eye of the pilot, determining a reference direction relative to the given frame of reference, comparing the eye gaze direction with the reference direction, and if the eve gaze direction and the reference direction are equal to within a given degree of accuracy, generating audio output audible to the pilot and indicative of information associated with the reference direction.

Abstract: An optical system for receiving an incoming beam of electromagnetic radiation, for dividing it into a transmitted beam, containing a part of the wavelength band of the incoming beam, and a reflected beam, containing the remainder of the wavelengths in the incoming beam, and for transferring the transmitted beam continuously to a detector. The system is capable of switching the reflected beam between any one of two or more detectors. The system comprises an objective lens, a dichroic beamsplitter cube, a first detector, capable of detecting radiation in a first wavelength band, a second group of two or more detectors, each capable of detecting radiation in a second wavelength band and means of rotating the dichroic beamsplitter cube, so as to switch between the detectors of the second group.

Abstract: A method and system for monitoring a region of interest are presented. Incident radiation is transmitted towards the region of interest with a certain transmitting angle and with a predetermined angular intensity distribution of the incident radiation. The transmitting angle defines a plane of propagation of the incident radiation, the region of interest being located within this plane. Reflections of the incident radiation are collected with a solid angle of collection intersecting with said plane. A region of intersection presents a detecting window of a predetermined geometry containing at least a portion of the region of interest. The collected radiation coming from within the detecting window is detected, and output signals indicative thereof are generated.

Abstract: Method and apparatus for generating superheated steam from industrial grade hydrogen peroxide. Hydrogen peroxide and a combustible fluid are injected into a first part of the combustion chamber to form a reactant mixture. The reactant mixture is ignited, to allow for the decomposition of hydrogen peroxide and the generation of superheated steam, which exits from a second part of the combustion chamber. An improved combustion efficiency is realized with the implementation of a flame holder.

Abstract: A soft removable thermal shiled for protecting a heat-sensitive element of a projectile. The shield includes a main body and an attachment arrangement forconnecting the main body to the projectile. The main body is designed to cover part of a window of the projectile, behind which the element is disposed. The main body is designed also to thermally protect the element during part of the flight of the projectile, and to be soft enough when released from the projectile, so that the main body does not harm the projectile after it is released.
