Abstract: Methods, systems, and apparatuses are described causing light to be emitted, causing a frequency at which the light is emitted to vary, receiving, based on the frequency variation, a user input, determining a critical flicker frequency (CFF) corresponding to the user input, and determining, based on the CFF, a disease state.

Abstract: A method and apparatus for displaying an image of terrain obtained from a position above the terrain. An image of an object is detected in the image of the terrain for an object that is positioned between the terrain and the position above the terrain. The detected image of the object is replaced in the image of the terrain with replacement image data. For example, the replacement image data may be image data for the terrain below the object. The image of the terrain with the replacement image data may be displayed. The method and apparatus may be used to replace images of clouds in images of the surface of the earth below an aircraft with image data for the surface of the earth below the clouds.

Abstract: A flight portal apparatus for displaying a virtual view of a surface of the earth below an aircraft. The apparatus comprises a data processing system and a display device, connected to the data processing system, wherein the display device is positioned to generate a display that is substantially horizontal relative to a floor of an aircraft in a manner that simulates a portal in the aircraft. A camera system is connected to the data processing system, wherein the camera system generates video data of the surface of the earth below the aircraft. A user input system is connected to the data processing system.

Abstract: An interactive switch system for a stowage compartment system for a mobile platform (for example, commercial aircraft) is provided. An electronic latching system adapted for use on a moveable compartment that moves relative to a support structure from an opened to a closed position is provided. The electronic latching system includes a switch coupled to the moveable compartment for receiving an input signal indicative of a desired operation of the moveable compartment, and a latch pin coupled to the moveable compartment. The system also includes a latch receiver coupled to the support structure to receive the latch pin to secure the moveable compartment in the closed position, and for releasing the latch pin to enable the moveable compartment to enter the opened position. The system further includes a control system in communication with the switch and the latch receiver to receive the input signal. The control system signals the latch receiver to secure or release the latch pin based on the input signal.
