The invention provides an ophthalmic illuminator, including a battery, an electrical resistor, an electrical switch and an LED. A substrate defined with a device region is provided. , a mainframe computer, which includes as part thereof a housing having therein an electrical assembly including a circuitized substrate which in turn includes a plurality of contiguous open segments which define facing edge portions within an electrically conductive layer to isolate separate portions of the conductive layer such that the layer can be used for different functions, e. Moreover, a distribution component can be configured to distribute the one or more service policies to one or more policy servers of the network; or forward information of the one or more service policies to another network. The data set includes parameter configurations matched with observed ratings of efficacy on patients of a similar indication. A second security state is indicative of denying delivery of the inbound message to the user.
