An exemplary embodiment of a method of making an electromagnetic interference absorber includes stretching a material that includes EMI absorbing particles along at least a first axis to align at least some EMI absorbing particles. When a movement of the outer sleeve is stopped, the outer sleeve moves the inner sleeve for releasing the inner sleeve from the first rotor and for releasing the inner sleeve from the outer sleeve. The switch includes two voltage followers, one of which turns off the switch to set the time constant in a longer state; while, the other of which turns on the switch and reflects the input of the integrator to set the time constant in a shorter state.
