A technique for controlling a power supply with power supply control element with a tap element. The device includes a wireless signal receiving module, a storing module, a speaker module and a processing module. The data entered is processed to process and audit clinical procedures and costs. The wide FOV lens system is superposed over an outer surface of the electromagnetic radiation sensitive device, the electromagnetic radiation sensitive device is capable of interacting with the incident electromagnetic radiation. The system of the present invention provides constructs and methods for: discovering and selecting a multihoming server; selecting a primary media access control address; associating multiple link addresses with a MAC address; and forwarding packets via the multihoming server based on certain defined policies. The mobile device gateway server acts as a middle tier between one or more enterprise databases and one or more mobile devices or any network-enabled thin client.
