Abstract: The present disclosure pertains to a system for providing persistent mission data to a fleet of vehicles. In some implementations, the system receives (i) information related to a first vehicle's location, the altitude of the first vehicle, and the first vehicle's orientation from the one or more first sensors and (ii) imagery data from one or more second sensors disposed on the first vehicle, wherein the imagery data includes instantaneous imagery and previously recorded imagery. The system geolocates the imagery data based on the first vehicle's altitude and the first vehicle's orientation relative to the terrain. The system transmits one or both of the instantaneous imagery or the previously recorded imagery to a fleet of vehicles. The system effectuates presentation of the imagery data on a three dimensional topographical map of the terrain.

Abstract: The present disclosure pertains to a system for effectuating presentation of a terrain around a vehicle on a display in the vehicle. In some implementations, the system receives information related to the vehicle's location, the height above the ground surface of the terrain, and the vehicle's orientation from one or more first sensors coupled to the vehicle; obtains a three dimensional topographical map of a terrain around the vehicle based on the location of the vehicle; and receives imagery data from one or more second sensors coupled to the vehicle, the imagery data corresponding to the terrain, wherein the imagery data comprises instantaneous imagery and previously recorded imagery. The system effectuates presentation of the imagery data corresponding to the terrain on the three dimensional topographical map based on the location, the height above the ground surface of the terrain, and the orientation of the vehicle.

Abstract: An improved airplane toilet drain valve assembly comprising a rotatable valve mounted within a housing and a moveable sealing member which is arranged in contact with the valve surface when the valve is in a closed position and which during operation of the valve is moved away from the valve surface thereby avoid wear or damage due to friction between the seal and rotating valve. The invention further comprises a scraper member mounted within the valve housing which prevents solid waste materials from coming into contact with the seals.
