Method and apparatus for touch temperature management based on power consumption history

Abstract

Certain aspects of the invention relate to techniques for touch temperature management of wireless communication devices based on power drawn over time and possibly internal temperature readings. For example, information about power consumed over time may be used along with monitored internal temperatures of the device's internal circuitry to reduce transmit power and / or data rates as needed to keep the wireless device's surface temperature below specified limits. Knowledge of how a device's touch temperature varies with power consumed and knowledge of power consumption history can be used to determine when to reduce transmit power to avoid overheating (eg, exceeding touch temperature limits).

AI Technical Summary

Problems solved by technology

However, existing methods for measuring touch temperature can often be expensive and inefficient

[0008] Methods known in the art for limiting the touch temperature of a wireless communication device may throttle, for example, transmit power and / or data rate prematurely or more often than needed

These methods may not even be aware of touch temperature, and transmit power and data rates may be throttled based on one or more internal integrated circuit (IC) temperatures observed in the wireless device
