FlexSet offers better control of accelerometer power, noise

New York-based Kionix has unveiled the FlexSet performance optimiser for controlling accelerometer power and noise values. Featured in the Kionix KX022 (2x2mm) and KX023 (3x3mm) accelerometers, the FlexSet MEMS motion-sensing technology comes with an online graphical user interface (GUI) and has the ability to turn integrated algorithm engines on and off for a more efficient power consumption.

FlexSet improves the programmability of integrated algorithms that facilitate the implementation of system capabilities including screen rotation, Tap/Double-Tap and motion wake-up functions. The downloadable GUI in FlexSet enables system designers to tune the performance of their system through several switch selections and pull-down menus that provide various operational configurations such as sample averaging, operating modes, sample buffering and bandwidth. The interface demonstrates the resulting impact on power consumption and noise and lets designers do side by side comparisons of various accelerometer settings using the "Compare Cases" mode.

Kionix developed FlexSet to give designers "the opportunity to use their skills and experience to fine tune a critical component within their systems" using resources that are not seen in existing standard user-selectable parameters, said John Chong, the company's director of product engineering.
