Disclosed is a composite diving board supported by nonlinear leaf springs, in which the spring cross section transitions from wide and thin at the ends to narrower and thicker at the center, while always maintaining approximately the same cross section at all points. The amount of elapsed time a user spends on a program channel is monitored. A method of fabricating the semiconductor structure is also described. In either embodiment, the membrane or foam contain a penetration zone defined by any number of intersecting slits. A second optimization is performed to meet a second objective allowing uniquified instances of the at least one reused cell to be independently modified. The first command has the unique behavior when the first command only operates in the first color space.
