Abstract

With the popularity of communication devices increasing (i.e. pagers, cellular phones), it becomes apparent that more features must be offered in order to make these devices more multi-functional and therefore more appealing to the customer. A wmmunication device with a temperature sensing circuit and a temperature readout either incorporated into an existing display or on a dedicated display would make such a device both multi-functional and more user appealing.

TEMPERATURE SENSING COMMUNICATION DEVICE

by Brad Murray

   With the popularity of communication devices increasing (i.e. pagers, cellular phones), it becomes apparent that more features must be offered in order to make these devices more multi-functional and therefore more appealing to the customer. A wmmunication device with a temperature sensing circuit and a temperature readout either incorporated into an existing display or on a dedicated display would make such a device both multi-functional and more user appealing.

   With the never ending need for higher quality wmmunication devices, it becomes apparent that new diagnostic tools must be sought in order to continually improve the quality of our products. One such tool would be the use of a temperature sensing circuit incorporated with an EEPROM that could store both high and low temperature peaks so as to better understand the environments these products are subjected to. Temperature information could also be stored at the time a product fails and could be read back during servicing to assist failure analysis.

   A third use for atemperature sensing circuit in a communication device would be for error correction in an oscillator circuit that is temperature sensitive by design or is used under extreme conditions not normally seen by most com- munication devices.

All three of these suggested uses could be incorporated at the same time in a communication device i...
