Devices, systems and methods of using an ergonomic fore gripgun handle with a concealable and collapsible bipod. Each sub-system and system component has a sensor element for determining status information thereof. The first substrate and the second substrate may be joined together by anode coupling. The pump is configured to be operated continuously or in a pulsatile fashion, synchronous with the patient’s heart, thereby potentially reducing the afterload of the heart. The system is especially well suited to providing interworking between ANSI-based and GSM-based mobile networks, although other types of networks are contemplated.
