Volume Production of Optimized Combination Gyro-Sensor

EL SEGUNDO, CA--(Marketwire -) - Epson Toyocom Corporation's U.S.-based Timing Products Division announced it has completed commercial development and launched volume production of its newest high-sensitivity gyro-sensor. The critically enhanced XV-3700CB is the industry's first to combine a high-sensitivity gyro-sensor with a wide detection range that has been optimized as an input device for motion user interfaces. Production level samples are available now.

To-date, existing sensor products have not been able to simultaneously provide both a wide sensing range and good stability and noise characteristics. To facilitate this demand to sense the motion of persons or objects more accurately requires that angular velocity be sensed over a wide range, from slow speeds to fast. The XV-3700CB not only retains the low noise level and outstanding bias stability of Epson Toyocom's current XV-3500CB but, in addition, accurately senses motion over a wide range by simultaneously outputting two modes, a high-speed mode (sensing range: ±1500°/s) with a nominal scale factor of 0.8 mV/(° s–1), and a low-speed mode (sensing range: ±300°/s) with a nominal scale factor of 3.624 mV/ (° s–1).

Used for analyzing human motion or as an input device for a motion user interface that accurately senses, for example, the altitude of a radio-controlled helicopter, the new gyro-sensor will help improve the performance of devices designed for even the most critical and intuitive motion sensing applications, such as controllers and 3D mice.

Main Features
1) Capable of sensing both slow and fast motion, with low-speed and high-speed modes in a single package
2) Supports simultaneous dual signal output thanks to Epson Toyocom's analog circuit technology
3) Achieves a low noise level yet retains the performance of the XV-3500CB
4) High-precision QMEMS gyro element provides outstanding bias stability
