GPS and cellphone unit having add-on modules
First Claim
1. A hand-held communication device providing a position-locating function and a cellular telephone function, comprising:
- a hand-held core module having means for entering information including control information, means for displaying information, and first means for providing a first function;
a removable add-on module containing a battery and removably fixed to said core module for providing power to said first means, said removable add-on module also having second means integral therewith for providing a second function;
wherein said first function and said second function includes a GES function and a cell phone function; and
means for removably coupling power from the battery as well as control and information signals between said core module and said removable add-on module, wherein said core module includes means for controlling the second function provided by the removable add-on module;
whereby the hand-held core module and the removable add-on module are fixed together to provide an integral hand-held communication device containing a battery and having a position-locating function and a cellular telephone function.

Abstract
A GPS unit and a cellular telephone unit each have add-on modules for providing additional functionality. A battery powered hand-held GPS unit has a battery power module with a built-in cellular telephone. The controls on the GPS unit are used to control cellular telephone operations. The GPS controlled cellular telephone transmits position location information obtained by the GPS unit. Alternatively, a battery powered hand-held cellular telephone unit has a battery power module with a built-in GPS device. The controls on the cellular telephone portion are used to control GPS device operations. The cellular telephone portion is able to transmit position location information obtained by the GPS device. The GPS and a cellular telephone device can function with either a standard battery module, or with a battery module having a cellular telephone or a GPS device built into the battery module.
