    摘要： An airborne Icing Hazard Detector for aircraft uses dual frequency radar beams which are transmitted into a cloud ahead of the aircraft. The reflected signals at each of the two frequencies are compared and processed to determine the presence, amount and location of regions of liquid water in the cloud. The presence of liquid water is determined as a result of liquid water attenuating the power of one of the signals a greater amount than the other signal, due to different attenuation characteristics of the two signals at the two frequencies. A temperature sensor provides ambient temperature information to determine if the detected liquid water is super-cooled. Upon detection of a predetermined amount of liquid water and the determination that it is super-cooled, an advance warning indication is provided to allow the pilot to avoid flying through the volumetric region of supercooled liquid water and risking ice formation on the aircraft.

    摘要： The virtual reality imaging system takes a multidimensional space that contains real world objects and phenomena, be they static or dynamic in nature, and enables a user to define a point in and/or a path through this multidimensional space. The apparatus then displays the view to the user that would be seen from the point in and/or path through the multidimensional space. This view is filtered through user definable characteristics that refine the real world phenomena and objects to a perspective that is of interest to the user. This filtered view presents the user with a virtual view of the reality contained within this multidimensional space, which virtual reality presents data to the user of only objects, views and phenomena that are of particular interest to the user. The system also stores a plurality of states of the multidimensional space so that the user can replay the generated display or can modify the user selected point in and/or path through this multidimensional space and/or modify the user definable characteristics that define the filtered view.
