An SOI substrate has a first region isolated from a second region. A surface association system for a healthcare facility may comprise a plurality of beds. LEDs satisfy the relationship of: a distribution range of light emitted from G-LEDs<a distribution range of light emitted from R-LEDs, or a distribution range of light emitted from G-LEDs<a distribution range of light emitted from B-LEDs. Once executed, the at least one control script may be configured to access a native application programming interface of the second computing device to cause graphical data to be presented via an output interface communicatively coupled to the second computing device based on a context defined by the at least one control object.
