The Anomalous Environment Recorder (AE Recorder) provides a robust data recording capability for multiple high-shock applications including earth penetrators. The AE Recorder, packaged as a 2.4" di ameter cylinder 3" tall, acquires 12 accelerometer, 2 auxiliary, and 6 discrete signal channels at 250k samples / second. Recording depth is 213 seconds plus 75ms of pre-trigger data. The mechanical, electrical, and firmware are described as well as support electro nics designed for the first use of the recorder.

The 3AMP Interim penetrator instrumentation data recorder replaces the original 3AMP design that became unavailable due to sunset electronic components. The revised design meets or exceeds the capabilities of the original design. The 3AMP Interim records six analog channels at 75k samples per second, with a recording time of 581 milliseconds. The 3AMP was designed for sub-scale penetrator tests, but found application in a variety of testing where an extremely robust acceleration recorder was required. This report describes the 3AMP Interim design including schematics and firmware, plus the user interface software used to configure the device as well as extract data post-test.

The Burn Diagnostic and Laser Debridement project, CRADA Number SC93/01177 between Sandia and Wellman Laboratories of Photomedicine, will develop a prototype system for human trials of burn injury treatment using optical-based diagnostics and laser debridement. This quarterly progress report for July through September 1995 combines contributions from all team members on the project. The primary emphasis this quarter was completion of the Prototype Design Review. The review was conducted in two sessions, first at Sandia and second at Wellman. The objectives were to validate the requirements, compare the design intent with the stated requirements, critique the design, and conclude with a rating of acceptable, conditionally acceptable, or unacceptable. Although the design was rated conditionally acceptable at Sandia, the Wellman researchers felt too many issues were unresolved and therefore could not support that rating. The authors have initiated a plan to rapidly reach consensus on the remaining unresolved requirement issues so that construction of the Prototype II system can begin.
