A plurality of radio base stations connected to a network are divided into radio base stations of the upper-level version having a specific function and radio base stations of lower-level version not having the specific function. A request to establish a communications link between a communications module of the vehicle and an external device associated with a user of the vehicle from the external device is received by a communications module. The filling apparatus can comprise an assay input layer having a first surface and an opposing second surface. The signal processing circuitry communicates with the sensor, and includes data analysis circuitry and memory. The matrix is solved resulting in an eigenvector that holds the optical centers that are used to output image information. One of the stages of the water treatment is subjecting the water to electrocoagulation so that colloidal solids can be reduced, emulsions broken, and hydrocarbons and complex organics removed, without the application of substantial chemical substances to the contaminated water or even the use of any chemical substances.
