Slide 5 of Roth has the sensors that QUIK has worked to insure compatibility with  we have Bosch and ST and INVN, and can be happy they are there.  Some other names are there and I want to see what they have...

ADI- they sold their microphones to INVN what else do they have?

muRata- I have tracked them for a good bit

Why?

Murata and Sensor Platforms Collaborate on MEMS Sensor and PDR Algorithms for Next-Generation Smartphone/Tablet Applications

KYOTO, Japan, Jan 06, 2014 (BUSINESS WIRE) -- Murata Manufacturing Co., Ltd. (tokyo:6981) (isin:JP3914400001) (hereinafter "Murata") and Sensor Platforms, Inc. (hereinafter "SPI") announced today they have had a collaborative relationship for over three years.

The indoor navigation, activity-monitoring market will become a reality now that Murata and SPI have teamed up. The newly developed best PDR (Pedestrian Dead Reckoning) algorithm by SPI, combined with Murata's high-accuracy, low-power, low noise MEMS technology (pressure sensor currently under development), will minimize the error over distance traveled, bringing much needed accuracy to the PDR market. It will lead to a first in consumer satisfaction. By using SPI's PDR function, customers are able to detect position, utilizing a variety of sensors with their algorithm. With Murata's MEMS sensor high-accuracy height detection added into this function, it will enable precise Z-axis information, enabling users to freely move around the third dimension world. Minimum power consumption is always a critical issue for smartphone/tablet devices, however this will also be accomplished by utilizing both Murata's hardware and SPI's software.

They make some very interesting and good sensors. Pressure is a strong point for them, ie the one for the 10th axis for Indoor location.
