An electrical actuator has a DC motor which is provided with a rotor having a permanent magnet for forming a plurality of magnetic poles around a periphery thereof and a stator having a plurality of energizing coils and being disposed around a periphery of the rotor to thereby generate a rotary force for the rotor. The intermediate substrate holder includes at least one of a vacuum holder and a mechanical clamp. The openshort digital signal may be supplied as a signal representative of applied key pressure to a legacy keyboard key matrix and controller or other processing device of an information handling system that is configured to measure keyboard input based on \u201cmomentary-on\u201d digital signals. The invention provides in-gel chemical tagging method for phosphoaminoacid residue of phosphoproteins retained in polymeric gel matrix. The reinforcer can be positioned integrally within the beam, or attached to a rear of the beam where the beam has a rearwardly open section, or attached to a front of the beam such as to stiffen the front of the beam.
