Between the sides of the runway there is a monitoring member which provides an electrical signal in accordance with the depth of standing water on the runway. A series of spaced electrode sensors which are calibrated in spaced-apart relation to each other provide signal outputs directly related to water depth. At the sides of the runway are a second series of electrode sensors which are spaced by graduated vertical distances to measure the depth of standing water at the sides of the runways. The signals from all these sensors are then communicated to a display device which provides a visual readout of the depth and location of standing water on the runway, which information can then be communicated to pilots of aircraft prior to landing or taking off. Information of standing water is essential to the safe operation of aircraft since excessive standing water on runways can cause a drowning out of the aircraft jet engines or cause dangerous sliding and skidding of the aircraft on the runway. The sensor signals are transmitted for example, through the runway light system, and a multiplexing device then conveys the signals to a display for visual readout of the water depth-and-location information.,下面是Apparatus for continuously monitoring standing water on aircraft runways专利的具体信息内容。

1. Apparatus for continuously sensing and monitoring standing water at remote locations on aircraft runways and the like comprising a plurality of nonelectrically conductive blocks disposed at selected locations on the runway and superimposed thereon each such block having calibrated electrode sensor means embedded at spaced vertical calibrated positions within said block and having an exposed probe means at the outer surface of the block and which is insensitive to water except in the liquid phase thereof, such electrode sensor means being selectively energized in response to the water depth at a particular height at the preselected location, electrical signalling means responsive to said electrode sensor means and electrically connected with said sensing means, and a display which is responsive to said electrical sensing means to provide a visual indication of the location and depth of standing water on the runways.
2. The apparatus in accordance with claim 1 wherein said blocks are configured with a hemispherical outer surface to provide for a rolling action of aircraft tires thereover without disturbance of the location of said block.
3. The apparatus in accordance with claim 1 wherein said electrode sensors are spaced calibrated distances apart whereby said electrodes provide direct information as to the standing water at the particular location.
4. The apparatus in accordance with claim 1 wherein said electrode sensor means provide electrical signals, of alternating current, and said display includes liquid crystal materials.
5. The apparatus in accordance with claim 1 wherein said display consists of liquid crystal elements in parallel with a microammeter.
6. The device in accordance with claim 1 including collector means disposed at the runway level and including an inlet for receiving standing water on the runway, and for developing a standing column of water equal to the depth of standing water at the same location, and a plurality of electrodes disposed at calibrated heights and responsive to the height of fluid which is standing on the runway surface.
7. The apparatus in accordance with claim 6 wherein said plurality of electrodes are disposed at the side of the runway and spaced at graduated distances from the runway surface to be responsive to water level at successive levels on said runway.
