DMU41 Highlights • 9 DoF inertial measurement unit • Unit volume, weight and power consumption reduced 40%+ • 50 x 50 x 50mm

Last month Silicon Sensing Systems launched a new 9 degrees of freedom (DoF) • Weighs 200g inertial measurement unit (IMU) which offers a dramatic reduction in volume, • Typical power consumption weight and power consumption. Dr. Mark Marshall (above) Consultant Engineer, of less than 1.5w

Silicon Sensing, discusses the unit and the technology behind it.

Obviously we’re here to discuss the capabilities and the It appears that you certainly have packed a lot into a very technical aspects of the new DMU41, but to start in the small package. From an engineering and manufacturing macro, what was the impetus?

Basically we went and asked our customers (and prospects) We’ve used a lot of advanced manufacturing techniques. We’ve what they required next, what they needed for their future borrowed some ideas from the mobile phone industry and products. It became very apparent that the customer wanted we’ve used some very high-performance processors within the something a little smaller, equally as well performing as the package itself.
