4-Directional Tilt Sensor - New

Right before closing the office for the holidays we released a neat new sensor. Im not sure we posted any release, so Im posting a forum message now.
The new sensor is called 4-Directional Tilt sensor and chances are that most of the gadgets you received as Christmas presents have one of these sensors inside. (If your camera or smart phone knows which way is up it has this kind of sensor inside).
This simple sensor is economically convenient (just $4.99) for applications that dont require detailed information about inclination angle or acceleration value, as you can obtain from the Memsic 2125 (for $29.99).

Keeping the hobbiest and student in mind here.

Many thanks for an inexpensive sensor.
Also, I'm a little confused by this statement on page 2: I can see how the cylinder would be in position C if the unit is spinning around by its central axis (the axis going into the paper with the centrifugal effect moving the cylinder "up against the wall"). Is that what they are talking about?
Well, maybe I'm just splitting hairs here or maybe I'm missing something, but maybe the illustration should indicate which way the gravitational or acceleration vector is meant to be aiming?
I had quite a bit of trouble with the difference between an accelerometer and a gyro and a rate gyro - now we are stepping away from 3 axis of roll, pitch and yaw and into a 4 directional Tilt sensor.
Something tells me that this terminology is going to open a can of worms. But it certainly isn't a gyro or an accelerometer - it seems that it just senses rotation when something is held perpendicular to the ground plane (just one axis).
Thanks for the informtion.
Please notice: We only consider the low speed applications, in the follow discussion we will ignore the centrifugal.
Yes, it's suiteable to call it 4- position tilt sensor, and would easier to be understood without misleading.(We would consider about this, but we had already put the product in our system. Changing names will cause some issues.)
You are right.The sensor need the help from the G-forces to change the status, so the cylinder will not respond if the sensor no tilted at all, and will remains in the last location.
I am afraid not. I'd rather to say that's a slip of the document, in this discussion we would ingore the centrifugal.
And yes it would cause some issues with the way we say in the PDF document. If we need to say so we should define how the g-force goes first, and how we put the sensor, like this:
Thanks again for the messages. We will revise the document soon.
