CHANGING MODES IN A DEVICE

摘要

A method is provided of changing between modes in a device. The method comprises changing the mode of the device in response to a change in the temperature of a first point of the device relative to the temperature of a second point of the device. Such a change in temperature may be created, for example, by the body heat from a user picking the device up. In certain embodiments, this allows the device to be switched between a completely powered-down mode to a powered-on mode without consuming any power in the powered-down mode. Further, the method provides a convenient and user- friendly way of operating the device.
