An amplification arrangement comprises a signal-processing element with an integrator element that is coupled on the input side with a first input for feeding the input signal and with a second input for feeding a feedback signal. As a result of the rotation of the turn-key member, the catch rod has two positions\u2014a \u201clock\u201d position that does not engage a swiveling trip lever, and an \u201cunlocked\u201d position that engages the swiveling trip lever. The at least one strap adjustably attaches the pouch to a futon frame assembly. The valve is operably coupled to an electrical actuator and is moveable between, at least, a first position and a second position. For example, both amplitude and phase coding can be applied to the sub-band signals. The first doping density and the lateral distance Lbe are selected to provide a parasitic base-emitter resistance Rbe in the range of 1<Rbe<800 Ohms.
