An image capturing device includes a pre-capturing module, a conversion module, a division module, a ranging module, a calculation module, and an image capturing module. Also included are methods of treating patients suffering from or susceptible to at least one symptom of abuse of, dependence on, or withdrawal from at least one substance. By observing network behavior instead of necessarily relying on user self-reported data, accurate and objective user profiles can be formed; user profiling is accomplished based on the observed network behaviors with or without the knowledge of the user being profiled. An insulation layer is arranged at least in places on the first semiconductor body and the insulation material, on which layer a planar conductive structure is arranged for planar contacting of the first semiconductor body, which conductive structure is electrically conductively connected with the electrical connection region. The Al2O3 layer is expected to provide similar antireflection properties and chemical protection for doped layers fabricated using other methods, such as MBE, ion implantation and CVD deposition. The request identifies a source and a destination of a path.
