An eye-mountable device for measuring an intraocular pressure is provided. One example of soluble CTLA4 mutant molecule is L104EA29YIg. This is done because a display size may have a significant impact on the effectiveness of certain applications. The degree of cross-linking is selectively modified by the degree of UV exposure to which the balloon article is exposed, andor the relative proportion of the cross-linking agent, to achieve corresponding product characteristics ranging from semi-compliant to non-compliant polyurethane film properties, including low creepsemi-compliant films. The bit fail map provides all the fail memory locations derived by the logical-to-physical mapping software. When controlling the position of the object lens in the tracking direction, first, an attempt is made to read address information recorded on the recording medium, and if the address information is not readable, the polarity of the tracking error signal used for servo control is reversed.
