Patent ID: 7231531

Claim:
In combination for processing information in a hand-held device, a hand held source of energy, a first system processor operatively coupled to the source of energy for performing first functions that are relatively simple, a second system processor operatively coupled to the source of energy for performing second functions more complicated than the first functions, the first and second system processors being operably coupled to provide for the first system processor to regulate the operation of the second system processor, without instructions to the first system processor from the second system processor, in performing the individual ones of the second functions, and a temperature regulator responsive to changes in the temperatures of the first and second system processor above a particular value for providing for variations in the frequency of operation of the first system processor to maintain the temperature of the first system processor below the particular value, the first system processor being operative in accordance with the changes in the frequency of operation of the first system processor to change the frequency of operation of the second system processor in a direction to reduce the temperature of the second system processor below the particular value.
