Matt, I'm hoping the tri-axial accelerometer data will sample fast enough to provide both acceleration and the integral velocity at rates fast enough to be sampled throughout the paddle stroke. The specification sheet suggests about 3000 samples per second compared to the combined GPS accelerometer with 1 sample per second for the GPS and ten samples per second for its inbuilt accelerometer. If the triaxial unit performs as per the spec then we could time link it to the paddle by fitting a blue tooth link to the paddle data stream removing the need to fasten the GPS to the paddle. The combine GPS accelerometer then becomes a measurement device to offset drift in the accelerometer integral velocity and it may not even be necessary to have this additional device. Alternatively we could take the tri-axial data from the paddle and interpret it, if its coming fast enough. I haven't heard back from the Talon people about a definite meeting time though they did say they were happy to meet. I'll try putting the questions in an email to them. We'll know just how well this could work with the Talon paddle once the triaxial unit we've ordered arrives and of course will send you the results as soon as we get them. All the best, PeterO <br><br><br>------- Original Message ------- On 7/30/2010 12:57 PM MATT MARINER BROZE wrote:<br>Thanks, <br> <br>The Bluetooth GPS device might be able to be used (attached to the Talon <br>paddle) to match in time (stroke for stroke) the angular data from the Talon <br>paddle's built in sensors and then we could know the kayak's speed via this <br>Bluetooth GPS devices GPS at the same time the Talon paddle was providing drag <br>measurements in the direction the kayak was moving with its built in strain <br>guages. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
