Kionix Sensors – CES

0

 We talked about new product releases and ongoing developments during CES. They want to address the question "where do you process the data from your sensors?" There are many tradeoffs between a MCU and CPU, but making scalable sensor solutions combined with intelligent power management can help. Their products use a combination of MEMS and ASICs to simplify design-in into systems.

They introduced a raft of new products to address the range of requirements for motion sensors. The new parts address power consumption through low power design and a configurable wake up function that powers up with a selectable level of motion.

The KXG02 is a combined 3-axis gyro and 3-axis accelerometer to enable six degrees of freedom for various consumer devices. The part can be mated with a magnetometer to provide three additional degrees of freedom.

Mobile handsets are the target for the KXTJ2 2x2x0.9 mm accelerometer. This part offers low power and high performance along with small size. The outputs are user selectable for range, resolution, and data rate.

The KXCJ9 3-axis accelerometer uses a new sense element for better performance. The part is pin compatible with earlier products for drop-in upgrades in small systems.

The second-generation gyro KGY23 offers lower power than its predecessor. The 3-axis MEMS sensor offers user programmable range and bandwidth. The part has a noise density of 0.30 deg/sec/?Hz and a 50 ms power-up time.

Developing the basic sensors and integrating them into a packaged device is only part of the product. Users cannot become sensor integration experts if they have to create the drivers and sensing code. The KXT9 3-axis accelerometer has an embedded algorithm to detect quick, light, or double taps from any axis. The output signal indicates tap and direction to offer manufacturers the ability to make new user experiences.

Another software development is the Gesture Designer. The embedded software engine
works as a code library from which user-specific, gesture-based commands can be created and managed. Although many of the functions are embedded into the products, users still need significant software development help. Kionix offers drivers, reference designs, and applications support to help their customers design motion sensing into their products.
