Record and playback system for aircraft
First Claim
1. A multi-media data collection, transmission, storage and playback system for reconstructing in flight events on an aircraft having on board time, altitude and geographic position monitors capable of sending a logging signal, the system comprising:
- a. a plurality of sensors each adapted for monitoring a selected condition aboard the aircraft, each sensor adapted for generating a unique data signal representing the specific condition to be monitored;
b. a collector adapted for collecting the plurality of data signals from the plurality of sensors and tracking the plurality of data signals with the logging signal and generating therefrom a combined signal incorporating each of the plurality of signals into a combined output signal; and
c. a processing system for receiving and processing the combined output signal, the processing system adapted for preserving critical elements in the combined output signal specifically indicating a change in condition at any of the plurality of sensors;
d. a recording and playback system for recording the time, the altitude and geographic location of the aircraft and change in condition of each of the plurality of sensors, whereby changes in condition of the sensors can be later recalled to determine the time, altitude and geographic position of the aircraft when an event occurred, as well as the time and type of event depending on the change in condition of the plurality of sensors.

Abstract
Multiple data and images are multiplexed and sequenced utilizing split screen technology in order to minimize the recording and monitoring hardware required to process the images, providing a detailed record of the time of an event, the altitude and geographic location of the aircraft and the type and location of the event within the aircraft, greatly enhancing event reconstruction efforts. The multi-media safety and surveillance system for aircraft incorporates a plurality of strategically spaced sensors including video imaging generators for monitoring critical components and critical areas of both the interior and the exterior of the aircraft. The captured data and images are recorded and may be transmitted to ground control stations for real time or near real time surveillance. The system is tied directly into the global positioning system of the aircraft so that the precise location of the aircraft may be determined when an event occurs.
