A method for filtering a digital signal sequence with adaptive filters given assistance of discrete parameter wavelet transformation is recited that, among other things, can be utilized in telecommunication technology for echo compensation. The device produces one or more stimuli: for example, it may display words on an LED screen, emit a sound, shine a light, vibrate, induce a warming or cooling sensation, or induce a shock. In a method of the invention, the substantially non-antigenic polymer is conjugated to a TA1 peptide. The closure mechanism may then be actuated, for example, by igniting a pyrotechnic within a specially designed bolt of the closure mechanism.
