An integrated connection assembly for a global positioning satellite (GPS) receiver
and a personal digital assistance (PDA) device or cellular phone. The integrated
connection assembly includes a power adapter, an interface circuitry, a filter
circuitry, and cable links. The power adapter has an external power connector adapted
to be connected to an external power source for obtaining an external power, and
an internal transformer and charger for converting the external power to an internal
power suitable for the GPS receiver and the PDA device or cellular phone. The interface
circuitry converts different interfaces of the GPS receiver and the PDA device
or cellular phone. The filter circuitry prevents interferences between the GPS
receiver and the PDA device or cellular phone. The integrated connection assembly
also includes component parts for providing connection to the GPS receiver and
the PDA device or cellular phone. The cable links electrically and electronically
interconnect and couple the power adapter, the interface circuitry, the filter
circuitry, the GPS receiver and the PDA device or cellular phone to provide the
internal power to the GPS receiver and the PDA device or cellular phone. At least
part of the cable links between the GPS connection and the PDA or cellular phone
connection is also capable of providing data transfer therebetween.
