By Business Wire News


Qualtré, Inc, a leader in the development and commercialization of Bulk Acoustic Wave (BAW) MEMS inertial sensors, announced today the availability of a MEMS sensor evaluation platform with 11 degrees of freedom (DOF). This evaluation platform combines 3 axes of gyroscopic data, 3 axes of accelerometer data, 3 axes of magnetic (compass) data, plus barometric pressure/altitude, and temperature. Qualtré’s sensor fusion application software library leverages the Atmel® SMART SAM4E Flash microcontroller based on the high-performance 32-bit ARM® Cortex®-M4 RISC processor and floating point unit (FPU).

“With an integrated sensor fusion framework, designers can focus on their unique motion based application,” said Dr. Sreeni Rao, Vice President of Vertical Markets, Qualtré, Inc. “It’s all about bringing the relevant data together from multiple sensors to provide a more comprehensive and accurate picture of what’s going on in a system. The Qualtré 11 DOF evaluation platform makes it easy to interface multiple sensors and get started immediately writing, compiling and running sensor based applications which can easily be ported to the end-user platform.”

11-DOF Sensor Platform

  • Qualtre 3-axis Gyroscope, Temp Sensor
  • ALPS Electric 3-axis Magnetometer, Pressure Sensor
  • Analog Devices 3-axis Accelerometer
  • Atmel Microcontroller

The current version of the sensor fusion platform provides software support for the following functions:

  • Wi-Fi-based 11-DOF Real-Time Telemetry
  • Sensor Fusion Quaternion Outputs
  • Corrected Heading Direction
  • 2nd Order Temperature Compensation

The key challenge in sensor fusion is effectively separating signal, motion, and noise. Qualtré’s algorithms aim to take data from different sensors that observe the same event to distinguish between noise and signals, then compute more accurate information. Sensor fusion encompasses a variety of techniques which leverage the environmental monitoring of the individual sensors and combine them intelligently to achieve broader and more accurate results.

Qualtré’s QGYR330Hx BAW MEMS™ Gyro was recently cited as a finalist for the “Best of Sensors Expo” awards to be announced on June 10. Previously, Qualtré was cited by EETimes as one of the top 15 MEMS/Analog startups to watch in 2015 and was included in EETimes list of “Silicon 60: Hot Startups.”
