Integrated connection assembly for global positioning system (GPS) receiver and personal digital assistance (PDA) device or cellular phones

摘要

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.
