IN-PLACE DATA RECORDER FOR AIRCRAFT TRANSPARENCY SYSTEMS

BY UTILIZMG MAGNETORESISTIVE RANDOM ACCESS MEMORY (MRAM) IN COMBINATION WITH SENSOR TECHNOLOGIES, NVE WILL DESIGN A COMPLETE DATA GATHERING AND STORAGE SYSTEM FOR AIRCRAFT TRANSPARENCY SYSTEMS WHICH WILL RECORD OPERATIONAL DATA DURING FLIGHT AS WELL AS DURING SHIPPING AND STORAGE. FABRICATION AND ASSEMBLY INFORMATION CAN EITHER BE ENTERED AFTER MANUFACTURING OPERATIONS ARE COMPLETE, OR DURING THE MANUFACTURMG PROCESS. IN ADDITION, ALL MAINTENANCE ACTIVITIES WILL BE RECORDED INTO THE SAME SYSTEM. ALL DATA MAY BE ACCESSED BY A STANDARD SERIAL PORT TO A DECOR IBM-COMPATIBLE SYSTEM MAKING THE HISTORY READILY AVAILABLE TO AIL MAINTENANCE AND RELIABILITY PERSONNEL. NVE'S "REAL TIME DATA ACQUISITION AND MAINTENANCE ASSISTANCE SYSTEM" (RTDMAS) WILL BE INSTILLED IN AND REMAIN IN THE TRANSPARENCY NODULE. USING THE HIGHLY RELIABLE SOLID STATE APPROACH OF THE MRAM TECHNOLOGY WITH ITS INHERENT BIT WRITABLE CAPABILITIES, UNLIMITED ENDURANCE AND EXCELLENT RETENTIVITY, NVE PROPOSES TO DESIGN A SYSTEM THAT WILL ALLOW THE AIR FORCE TO STORE THE COMPLETE RELEVANT HISTORY OF THE TRANSPARENCY SYSTEM.
