MULTIFUNCTIONAL CHARGER SYSTEM AND METHOD
First Claim
1. A mobile device, the mobile device configurable for use in a wireless telecommunications network, comprising:
- a Universal Serial Bus (“
USB”
) interface configured to allow reception of a USB cable;
a charging subsystem, the charging subsystem operably connected to the USB interface V-bus power line;
the charging subsystem operably connectable to a battery, and configured to charge a batter if a battery is operably connected;
the charging system further configured to use power from the V-bus power line for the charging of a battery; and
,where the mobile device is configured to detect an identification signal at a D+ and a D−
data line of the USB interface, the identification signal being different than USB enumeration.

Abstract
An adapter for providing a source of power to a mobile device through an industry standard port is provided. In accordance with one aspect of the invention, the adapter comprises a plug unit, a power converter, a primary connector, and an identification subsystem. The plug unit is operative to couple the adapter to a power socket and operative to receive energy from the power socket. The power converter is electrically coupled to the plug unit and is operable to regulate the received energy from the power socket and to output a power requirement to the mobile device. The primary connector is electrically coupled to the power converter and is operative to couple to the mobile device and to deliver the outputted power requirement to the mobile device. The identification subsystem is electrically coupled to the primary connector and is operative to provide an identification signal.
