SHOCK HARDENED ON-BOARD DATA ACQUISITION SYSTEM

THE OBJECTIVE OF THIS PROGRAM IS TO DEVELOP A COMPACT, RUGGED, TWELVE-CHANNEL (MINIMUM) DIGITAL DATA ACQUISITION SYSTEM CAPABLE OF MEASURING AND RECORDING SHOCK EXPERIENCES ASSOCIATED WITH WEAPON DELIVERY AND USE. THE SYSTEM MAY BE MODULAR, BUT EACH MODULE MUST CONTAIN FOUR DATA CHANNELS AND BE NO LONGER THAN 2.5 INCHES MAXIMUM DIMENSION. MECHANICAL DESIGN OF THE SYSTEM MUST BE SUCH THAT IT WILL OPERATE UNDER EXTREMES OF SHOCK, VIBRATION, PRESSURE, TEMPERATURE, AND HUMIDITY. SAMPLE RATES OF 10 KHZ AND 200 HZ ARE REQUIRED WITH SUFFICIENT MEMORY TO RECORD 400 MS OF 12-BIT DATA PER CHANNEL AT THE MAXIMUM SAMPLE RATE (I.E., 4000 SAMPLES OF 12 BITS EACH). EACH DATA CHANNEL SHALL HAVE INDEPENDENT, SOFTWARE-SELECTABLE TRIGGERING CRITERIA. PRE-TRIGGER DATA CAPTURE OF REFERENCE BASELINE IS REQUIRED. DATA RETRIEVAL SHALL BE COMPATIBLE WITH AN IBM PC/AT OR COMPATIBLE MICROCOMPUTER. THE SYSTEM SHALL BE POWERED BY INTERNAL BATTERIES AND BE CAPABLE OF RETAINING ACQUIRED DATA FOR A MINIMUM OF ONE MONTH. THE PROPOSED SYSTEM SHALL DIGITIZE ANALOG SIGNALS TO 12-BIT DIGITAL WORDS AT PROGRAMMABLE SAMPLE RATES FROM 200 SAMPLES PER SECOND (OR LESS) TO 10,000 SAMPLES PER SECOND (OR MORE).
