Overview
Murata Manufacturing Co., Ltd. completed the acquisition of VTI Technologies Oy (hereinafter "VTI" ) in January of this year, and integration is proceeding with the aim of making use of the synergies between the two companies. VTI's MEMS sensor products will be exhibited as part of the Murata Group for the first time at the 2012 AUTOMOTIVE ENGINEERING EXHIBITION to be held at the PACIFICO Yokohama from May 23 to May 25. At this exhibition, Murata will introduce VTI's acceleration sensors, gyro/accelerometer combo sensors, and pressure sensors.
Summary
VTI is a MEMS (Micro Electro Mechanical Systems) technology-based sensor manufacturer. MEMS technology is key for reducing device size, increasing accuracy and reliability, extending service life, increasing robustness, achieving lower prices, and reducing power consumption. By integrating MEMS technology into its own product lines, Murata aims to strengthen its development and sales abilities and ensure continued future growth for the expanding MEMS market, including a wide range of industrial and consumer applications such as automotive, information and communications equipment, energy, life care, and biotechnology.

Pressure sensors
Features
VTI's pressure sensors are low-noise, high-sensitivity MEMS element-type pressure sensors that use bulk MEMS technology*11. These sensors are manufactured under the same process and control conditions as VTI's MEMS elements, which have a solid record of over a decade of use for on-board applications.
Applications
- Medical devices
- Flow meters
- Barometers
- Altimeters

Terminology
- *1 Electronic parking brake (EPB)
This system adjusts the braking strength according to the angle of inclination in the longitudinal direction of the vehicle. The brake is locked simply by pressing a button on the instrument panel, and releases automatically when starting and accelerating the vehicle.
- *2 Hill start assistance (HAS)
This system automatically controls the brake pressure to prevent the vehicle from rolling backwards when starting on inclines.
- *3 Electronically controlled suspension (ECS)
ECS adjusts the suspension according to the driving conditions, taking into account the speed, the road surface condition, cornering, and acceleration and deceleration. The aim is to increase steering stability and driving comfort for the driver.
- *4 Anti-roll control (ARC)
This function prevents the vehicle from swaying heavily in the roll direction.
- *5 Roll over sensor (ROV)
These sensors detect vehicle body roll-over (roll-over in the roll direction) for airbag controllers.
- *6 Anti-vibration
This function detects and reduces engine vibration with the aim of reducing fuel consumption.
- *7 High bias stability
Extremely stable sensor output
- *8 Inertial measurement unit
A measuring instrument equipped with a three-axis gyro sensor and a three-axis accelerometer for monitoring the motion of an object.
- *9 Platform control
A system that controls a dynamic horizontal platform to always remain level.
- *10 Robotic technology control system
A control system for robots and devices that perform robotic operations.
- *11 Bulk MEMS technology
A MEMS manufacturing technology. This is the general term for technology used to manufacture MEMS devices by processing a substrate or thick film (thickness: several ten µm or more).
