Inertial measurement unit takes position
The MMQ50 is a compact inertial measurement unit designed to accurately measure vehicle movement and rugged enough to withstand the most demanding environments.
The MMQ50 is a compact inertial measurement unit (IMU) designed to accurately measure vehicle movement and rugged enough to withstand the most demanding environments In response to today's requirements for a small moderate performance IMU, the MMQ50 can be incorporated into either stabilisation or guidance and control applications in missiles, aircraft and robot vehicles

Two-axis positioning with voice-coil actuators
BEI Kimco Magnetics has a two-axis precision positioning system using a direct linear magnetic drive based on voice coil actuators which achieves sub-micron positioning with 50g+ acceleration rates
First electronic water level monitoring system?
BEI Edcliff Instruments introduces FluidTrax, an easy-to-use system for monitoring water levels in wells.
The small size, light weight, low power (4W) and wide bandwidth allow it to be incorporated into gimballed systems or provide the basis of a strap-down flight control system in smaller vehicles.
The MMQ50 provides attitude and velocity information enabling short-term guidance during loss of GPS signal.
With a volume of approximately 80cm3 (smaller than most mobile phones), it includes three solid-state quartz MEMS gyros and three silicon based MEMS linear accelerometers.
The MMQ uses existing inertial components already in volume production for the automotive market.
The internal digital signal processor thermally models the inertial sensors to correct for drift.
It outputs an RS644 serial digital signal, composed of angular velocities and linear accelerations, about the three orthogonal axes.
These are in incremental angle and velocity format (delta q, delta V).
Designed to meet stringent avionic environmental requirements, this rugged unit incorporates novel internal packaging techniques and is capable of meeting the demands of both manned and unmanned aircraft.
The MMQ incorporates flexibility in both the angular velocity and acceleration ranges available to meet specific customer requirements.
The MMQ50 offers high levels of performance at a low cost, combining the advantages of conventional IMU's with the accuracy and innovation normally associated with BEI products.
