At least one exemplary embodiment is directed to an imaging apparatus which can include a plurality of pixel sections disposed in a two-dimensional pattern. The combination also includes a furniture support and carpet protection apparatus for supporting furniture and reducing damage to the underlying carpet. Photoresist etching is performed through the hard mask and the doped polysilicon by using a photoresist mask. The gate structure is disposed on the substrate between the first and third doped regions. The load circuit is driven by the fourth power and has first and second operating modes and outputs an operating mode signal to the control circuit indicating in which mode it is being operated.
