Accelerometer
An accelerometer is a tool that measures proper acceleration. Another MEMS-based accelerometer is a thermal (or convective) accelerometer. It contains a small heater in a very small dome. wikipedia.org

How to extract specific frequencies in Discrete Fourier Transform. I'm collecting accelerometer data and interested in extracting frequencies from 1-10 Hz. I'm aware of how to do the FFT but not sure how to extract th...
Just take the inner product of your data with a complex exponential at the frequency of interest. If $g$ is your data, then just substitute for $f$ the value of the frequency you want (e.g., 1, 3, 10, ...): $$ \int_{-\infty}^{+\infty} g(t) e^{ -j2\pi f t } dt $$ Or if discrete: $$ \sum_{n=0}^{N-1} g...

Obtaining rotation matrix from Euler angles if all three rotations happen at once. Does order of multiplication matter? I'm having a problem getting my head around Euler Angles. Specifically if I wish to obtain a rot...
If you know the sequence of roll, pitch and yaw that you want to do in succession, you can find their matrices and multiply them together in the right order, and the three operations are performed "simultaneously." The order is important because the group of rotations is nonabelian. If you can produ...

Sensor fusioning in Kalman filter I'm interested, how is the dual input in a sensor fusioning setup in a Kalman filter modeled? Say for instance that you have an accelerometer and a gyro and want to present the "hor...
The Kalman filter can be used as is for two separate sensors, just consider a measurement at time $t$ to be $$y_t = [y^\mathrm{accel}_t, y^\mathrm{gyro}_t]'$$ and write the appropriate sensor noise covariance matrix ($H$). Your levels of confidence of the "good and bad" parts of the sensors, encoded...

How does a metronome help in controlling breathing rate? I'm new to the Bio/Medical field so kindly bear with me. I am doing studies on volunteers to formulate algorithms for evaluating Respiration rate from ECG and a...
The paper in question used metronome to aid test subjects control their breathing rate. This seems like a good approach, much better, than asking "please, breath with 0.1Hz frequency". > The subjects were asked to remain at rest in a supine position for 10 min, and then to **control their respirator...

DC SS009 7 PDF | PDF | Accelerometer | Electrical Engineering - Scribd
It is the first generation 3 axis acceleration sensor. Users could get acceleration values of X, Y, and Z axises. And it is widely used in. shock, slope, and moving detection. Output sensitivity could be selected by simply. setting voltage levels on a few pins. The measuring range is selectable among 1.5g, 3g, and 6g.
