Patent ID: 6976180

Claim:
A method of providing for the passage of information between a hand-held device and a second device displaced from the hand-held device, including the steps of: providing a first processor at the hand-held device, the first processor performing relatively simple functions, providing a second processor at the hand-held device, the second processor requiring a greater use of energy than the first processor, the second processor performing functions more complicated than the relatively simple functions performed by the first processor, providing a source of energy at the hand-held device for operating the first and second processors, providing normally for the operation of the first processor in processing data to perform the relatively simple functions and providing for the operation of the second processor, under the control of the first processor independently of the operation of the second processor, in processing data to perform the more complicated functions, storing data in the first processor for use in operating the second processor, and providing for the transfer of the data from the first processor to the second processor when the second processor is to be operated in performing the more complicated functions.
