An endograft for a vessel having a vascular branch extending from the vessel is provided. More specifically, a method and system for controlled access to content services where a terminal user can be allowed or refused access to a content service and the use thereof are disclosed. For example, the method may sequentially expose adjacent areas of semiconductor film to gated light in a first direction; and, simultaneously exposing adjacent areas of semiconductor film to gated light in a second direction, different than the first direction. In a particular embodiment of the invention, an electronic tool, such as a bi-directional scan tool, is used to perform the first and second requesting steps. The article can be any article, including but not limited to clothing and pictures. The compounds, compositions, and methods of the invention are also useful for treating and preventing Alzheimer’s Disease, Syndrome X, peroxisome proliferator activated receptor-related disorders, septicemia, thrombotic disorders, obesity, pancreatitis, hypertension, renal disease, cancer, inflammation, and impotence.
