This invention provides a driving aid to assist in detecting when a driver may become drowsy while at the wheel of a vehicle. The optoelectronic device includes an optical core feature located over a substrate, an outer cladding layer located over the optical core feature and a direct patch mask formed on an outer cladding layer. The image reject mixer further includes an in-phase transconductance stage coupled to an in-phase mixer of the quadrature phase mixer module and a quadrature phase mixer of the in-phase mixer module. The control unit controls, at the time of forward scanning by the light source, so as to detect the document size by the second document detection unit. The exposure power controller decreases the exposure power of the exposure unit for the toner-save printing mode compared to the exposure power of the exposure unit for the normal printing mode. A customizable software architecture allows customization of the image adjustment software module.
