Anyone know some material that could shield/block radio frequency pulses (around 58kHz.) I think aluminum works a little, anyone know what the best material would be, or any other material that would come to mind?

I used parts where u = e^-x^2 and dv = x but I cannot seem to get it. It keeps going on forever. I know the answer is -e^-x^2/2 from the Integrator. I tried using the method to get identical integrals on the left and divide it by 2 but I can never get that.

x * e^(-x^2)

Thanks.

In both instances, flying in a plane and scuba diving there is pressure in your ear. Can anyone find a chart on height compared to depth and the amount of pressure there is on your body? Eg. 30 ft deep is equivalent to 10000 ft high, and they both have 2 times the pressure? This is just an example and has no data behind it. That's what I'm looking for. I've had extreme problems in both instances as far as pressure on my middle ear and I want to know what is equivalent in both? Thanks.

Working on stabilizing an arm, but forward motion adversely affects the tilt output of the accelerometer (ADXL103). I know a gyroscope works but can't something like the wiimote be tilited and still not have that tilt be affected by the forward and backward movement of your hand? Thank you
