A transparent resin film for an electronic display and its manufacturing method are disclosed, the transparent resin film having an ultraviolet light transmittance of not less than 50%, the ultraviolet light having a wavelength range of from 250 to 450 nm, and having a glass transition temperature of not less than 180\xb0 C. A kit for use in rapid identification of these pregnancy complications is also provided. The first eye-tracking data can be associated with a first component. A detector is provided to detect by said slow dynamics induced material elastic modulus changes as indications of damages of the material or object. Both the diameter of each braking cylinder set and ratio of diameters between different braking cylinder sets are chosen to produce the optimum rear wheel braking pressure allocation for a given braking control system and vehicle configuration with no changes to the master cylinders or the front wheel braking system.
