The aim of the invention is to provide a solution to ensure that the content sent by the IRD is the content effectively displayed on the screen. The composition may also include an extracellular matrix scaffold component of any formulation, and further include added cells, proteins, or other components to optimize the regenerative process and restore cardiac function. The method is of particular utility in a low power FPGA that desirable has low static current leakage when in a static state. The method comprises: providing a first signal indicative of a light level; providing a second signal indicative of an environmental parameter, e. The driving-signal generating unit periodically inserts a noise image in the driving signal while maintaining timing for updating display of the frame image at the first period. The method may also include creating a dynamic map from the dynamic map template in response to discovering the dynamic map template.
