Ideal for Vehicle Test Applications in Dynamic Settings,

Including Auto, Instrumentation

Crossbow Technology, Inc., the leading supplier of low-cost, intelligent digital sensing solutions, today introduced the DMU(TM)-H6X six-axis inertial measurement unit (IMU) that provides six degrees of freedom with high performance and at a fraction of the cost of IMUs now available. The DMU-H6X is the second in a family of inertial subsystems with performance previously not available in sensors based on Micro-Electro-Mechanical Systems technology. It is designed for vehicle test applications, including automotive test, military vehicle test, instrumentation, and other measurement and test applications in dynamic environments. It is priced at only $2,995, far below the typical six-DOF IMU price of at least $5,000.

The DMU-H6X offers bias stability over temperature of +/- 1 degree in temperatures ranging from -40(Degree) to 85(Degree)C. The DMU-H6X measures X, Y, and Z acceleration as well as roll, pitch, yaw, and angular rates. No calibration is required.

The key to the outstanding performance of the DMU-H6X is the integrated Digital Signal Processor (DSP) coupled with proprietary algorithms that compensate the outputs for offsets, scale factors and alignment. All six of the DMU-H6X sensor elements (three angular rate sensors and three accelerometers) are highly reliable solid-state MEMs devices.

Crossbow's X-View software is shipped with the DMU-HDX for use on PCs running Microsoft Windows 95, 98 or 2000. X-View provides a convenient way to start system development, evaluate the performance of the DMU, and perform data acquisition.

The DMU-H6X package measures 3.0" x 3.75" x 3.25". It is available now. Crossbow Technology, Inc. is the leading supplier of low-cost, intelligent digital sensor solutions. Crossbow's sensors integrate silicon micromachining (MEMS) technology with digital signal processing. The sensors incorporate the company's proprietary SoftSensor(TM) embedded firmware, which includes algorithms for stabilization and navigation applications coupled with internal compensation and communication functions.
