ABSTRACT:
An apparatus for selectively activating a plurality of functional devices, including a charging circuit for a battery, has a connector for making connection intermediate a battery and its associated devices, such as a cellular telephone, a portable computer, a battery charger or a combination telephone/charger. The connection is coupled to a plurality of signal distinguishing devices, at least one of which is coupled with the battery charging circuit. Each signal distinguishing device is coupled directly or intermediately to one or more additional signal distinguishing devices or to more or more functional devices.
The plurality of signal distinguishing devices preferably includes a first frequency discriminating filter and a second frequency discriminating filter. The first frequency discriminating filter is coupled intermediate the charging pole of the battery and the battery charging circuit. The second frequency discriminating filter is coupled intermediate the charging pole of the battery and a second functional device. At least one selected frequency discriminating filter is a low pass filter and at least one selected frequency discriminating filter is a high pass filter. The apparatus, which may be connected by a single connection intermediate a battery and its associated electronic device, is preferably integrally packaged with the battery.
