The present document relates to voltage regulators. The sensor is operable to detect relative distance to the emitter to thereby detect the condition of the vehicle seat assembly. Ancillary circuitry has first and second operational modes and is coupled to the first and second processing stages so as to generate a first redundancy output corresponding to the first ECC based on the first output when operating in the first mode, and to generate a second redundancy output corresponding to the second ECC based on the second output when operating in the second mode. Then, in order to condition the psychological state, physiological state, or behavior of the subject, a second set of images, based on the personalized image response profile is displayed. On a rear surface of the conveyor belt is disposed an ink absorber for absorbing ink retained in the non-water-repellent region from the rear surface.
