According to one aspect, a portable electronic device having a heat generating component, a thermal sensor, an energy storage device for powering the portable electronic device, a thermal element thermally coupled to the heat generating component, the energy storage device, and the thermal sensor. The thermal element is sized and shaped so that heat generated by the heat generating component flows through the thermal element towards the thermal sensor and interacts with the energy storage device. The thermal sensor is used to monitor a thermal profile for the thermal element, and the monitored thermal profile is compared with an expected thermal profile to determine if the integrity of the portable electronic device has been compromised.

Methods and apparatus for detecting unauthorized batteries or tampering by monitoring a thermal profile

Systems and methods for facilitating an input to an electronic device are described herein. An example method for facilitating an input field of an electronic device includes presenting a menu item for selection while the electronic device is in a first physical state and identifying the menu item selected when the electronic device is in the first physical state. The method includes detecting whether the electronic device is in a second physical state after selection of the menu item and presenting an input field associated with the menu item selected.

A keypad assembly, and an associated method, is constructed in a manner to permit application of a finish, such as a decoration or painting, to any desired portion of the keys of the assembly, including at interstitial portions between adjacent keys. The keypad assembly includes a carrier membrane upon which keys forming a keypad array and key membrane pieces are supported. The carrier membrane is wrapped about a cylindrical fixture to position all portions of the keys in orientations to permit application of the finish thereto.
