    ADAS Locator

    MEMS sensors provide reliable, automotive qualified components for inertial navigation in Autonomous vehicle. A 6 DOF (Degrees Of Freedom) Inertial Measurement Unit provides data of the vehicle movement independent of the climate conditions, other vehicles in traffic, velocity of the vehicle and generally works as “voice of reason” in conditions where other sensor systems are confused. Integration of the IMU to GNSS enables positioning in situations with reduced GNSS reception or lack of GNSS signal. IMU integration also enables improvement of GNSS accuracy from scale of meters to centimeters, what is needed for positioning within lane.

    Opens new possibilities in patient monitoring and elderly care in hospitals, assisted living and even at homes. Embedded heart and respiration rate and beat-to-beat time signal processing enabling patient monitoring from bed occupancy to sleep condition analysis.

    Structure health monitoring

    MEMS sensors offer reasonably priced opportunities to build systems for Structural Health Monitoring. Murata MEMS sensor portfolio has options from highest accuracy and stability to solutions with low power consumption but yet high enough accuracy to monitor minor changes in structural health. Murata sensors offer very low noise level to measure disturbing events and stability to detect smallest changes of displacement.

    Agricultural

    Achieving positional adjustments is an ideal application for MEMS-based accelerometers and gyroscopes.Stability, noise and immunity to mechanical shock, all of which are vital for such precision agricultural applications involving moving heavy mach inery over undulating terrain. In this way the slope, direction of movement, and the change of the slope can be accurately measured. An accelerometer is used to measure the angle of inclination relative to the centre of the earth and a gyroscope is used to measure the speed that the angle changes.

    Weighting angle

    MEMS sensors offer reasonable priced opportunity to build system for both measuring the angle or build system for scale balancing. MEMS accelerometers and inclinometers can be used to get accurate angle reading and in a dynamic environment gyroscope can be used to achieve reliable measurement readings during movement. Murata MEMS sensors have options for the highest possible accuracy in most demanding application and robust sensing solutions to solve issues in moving machine environment. Murata sensors have excellent stability, resolution and linearity to measure smallest possible angles in all situations.
