/ Technical information made easy
We all live in this wonderful technical world but sometimes it just gets a little complicated. We therefore thought we should try to explain the functions of StingRay in a more user-friendly, easy to understand way. This is because we often watch people glaze over when we get technical!
What is tri-axis, gyroscope, magnetometer and accelerometer and how does the StingRay use them?
In simple terms:
A gyroscope measures rotational speed in degrees per second - in our case per millisecond, dpms. Therefore we can determine a heading or direction from the gyroscope.
An accelerometer measures acceleration relative to the earths gravitational pull - G force, which is typically 9.81m/s - meters per second, the speed at which we accelerate towards the earth when jumping out of an aircraft.
The magnetometer measures changes in the earths magnetic filed relative to magnetic north, as with a compass, this is measured in guass.
All three devices take readings on three axis: x, y and z (think of height, width and depth) providing a three dimensional view.
The key point with the three readings, when combined they can provide important spatial positioning information of the body they are attached to. A simple comparison would be that of an aircraft. By combining the three readings we can determine: heading, speed and attitude. Attitude in this case would refer to pitch, yaw and roll.
By recording this information at very fast speeds we can determine a track (or path) the object moves through. By using recursive learning algorithms (the clever maths) we can therefore identify what an object is doing and compare tracks over time to illustrate norms, anomalies or exceptions.
By having all these abilities the StingRay can tell you how you are moving, how fast, and monitor every part of your body moving if there is a sensor on a particular limb / part of your body.
What else can StingRay do?
StingRay can read your heart rate, oxygen levels, monitor UV levels and has a pressure and temperature function. From the last two it can accurately derive altitude. Its a given that we know the relative sea level air pressure (it doesn't change much around the world, but can be adjusted if greater accuracy is required depending on location) and average pressures as we rise and fall through the atmosphere, then a simple curve can be applied to convert the pressure reading into temperature.
Very simply put air pressure, which you get from an old school weather barometer can be directly related to altitude.
How will this data be recorded?
All of this data will be sent to a device via Bluetooth where it will be downloaded, analysed in an easy to use and understand format.
