Systems and techniques to determine a primary route between two locations by monitor vehicle speed using transmitting wireless devices. The method includes receiving shell selection information from a user input device, identifying a set of hardware components, the set of hardware components generated based on a compatibility between the hardware components and the shell selection information, and outputting the identified set of compatible hardware components. The discrimination apparatus further includes a discriminating unit configured to perform a discriminating processing on the subject to be discriminated, based on the color signals in the wavelength ranges noise-reduced by the noise reducing unit.
