A method and user interface for informing a user of the status of a network connection are provided. The method includes the steps of preparing an initial reference dye solution of unknown concentration from an initial reference dye concentrate and creating an electronic signal based upon the absorbance of the initial reference dye solution. A cap is removably attachable to the vial and when attached, the applicator portion of the applicator tip is accommodated in a cavity of the cap and a sealing stopper extends into the internal passage to thereby seal it. The motor is located within a space defined by the lens barrel and the film accommodating chamber, such that an output shaft extends in a plane normal to the optical axis. The sub-picture image includes a pixel data for each pixel in the sub-picture image indicative of a sub-picture pixel type including a background pixel type and a pattern pixel type. The ski has in its middle sliding skid zone a zone where its two lateral side edges are substantially parallel, each of the portions of the plate being connected to the ski via two lower wings that extend beneath the plate, both wings being pressed against the lateral side edges of the ski, and each wing being fixed to the ski via a single binding journal element.
