PUTTING SENSORS TO WORK
TOC Image Flight Testing the Black Hawk A sophisticated software program is helping Army test pilots and data analysts evaluate helicopter airworthiness.   Daniel R. Bryant and Randy Frank

TOC Image App Snaps Application Snapshots
Monitoring the temperature of curing concrete with a build-your-own DA system, securing a Flash drive with a fingerprint sensor, and using lasers to monitor vibration for the Air Force Institute of Technology.

INTELLIGENT SYSTEMS
Cover Story
TOC Image Modeling a MEMS Gyro to Determine the Maximum Operational Angular Rates and g-Forces A “virtual” MEMS gyro’s behavior was analyzed using software capable of modeling the mechanical and electrical effects of high rates and high accelerations.  Mark Weber et al.

An Attitude and Heading Reference System Based on Gyros, Flux Gates, and GPS Taking advantage of both solid-state gyros and GPS satellite data, a new attitude and heading reference system promises increased accuracy for experimental aviation pilots.   Mike Horton and Darren Liccardo

SENSOR TECHNOLOGY AND DESIGN
TOC Image IC Thermal Sensors Simplify Your Design Silicon-based IC temperature sensors may be the new kids on the block, but with their small size, integrated signal conditioning, and easy interfacing to microcontrollers, they’re rapidly increasing in popularity.  Matt Smith

A Magnetostrictive Torque Sensor A new fabrication technique solves the problem of an external magnetic field’s adverse effects on a magnetostrictive torque sensor.  Radu Andreescu et al.
