1. An activation circuit for an electronic device, comprising:
- a first heat sensor located on the electronic device in a first location where a user of the electronic device is expected to handle the electronic device;
a second heat sensor located on the electronic device in a second location where the user is not expected to handle the electronic device; and
an activation circuit to activate a component in the electronic device when the electronic device is ina first environment that is room temperature and a difference in readings between the first heat sensor and the second heat sensor exceeds a first threshold to activate the electronic device at room temperature;
and the activation circuit further conditionally adjusts readings from the second heat sensor to adjusted readings and activates the component whenthe electronic device is in a second environment having a second environment temperature reading that is less than room temperature whereby the second environment temperature reading is adjusted to a first adjusted reading, and the difference in readings between the first heat sensor and the first adjusted reading from the second heat sensor exceeds a second threshold to activate the electronic device at the temperature, the second threshold being different than the first threshold; and
the electronic device is in a third environment having a third environment temperature reading that is more than room temperature whereby the third environment temperature reading is adjusted to a second adjusted reading and the difference in readings between the first heat sensor and the second adjusted reading from the second heat sensor exceeds a third threshold to activate the electronic device at the temperature, the third threshold also being different than the first threshold.

Abstract
The disclosure provides a system and method for activating an electronic device. The activation circuit comprises: a first sensor to monitor for a first condition relating to an environment as affected by a user of the device; a second sensor to monitor for the first condition relating to an environment isolated from effects of the user; and an activation circuit to evaluate signals from the first and second sensors to determine whether to change an activation state of a component on the device. This may involve activating or deactivating the component.
