Abstract: A method and apparatus for thermal management of components and functional subsystems of a handheld device, including for a peripheral device electrically coupled to thereto. A power source provides power to a plurality of functional subsystems of the handheld device and optionally the peripheral device. The components and functional subsystems comprise predetermined thermal signatures.

Abstract: A novel capacitive sensing keyboard allows for keypads to be easily changed for repair or reconfiguration purposes. The keypads can be made of a deformable and resilient material, such as an elastomer, which can provide tactile feedback to a user and which are relatively inexpensive to manufacture. An array of overlying pairs of driver elements and sense elements are located adjacent the keypad and changes in the dielectric value of materials about the driver/sense element pairs are detected when a key on the keypad is pressed by a user. These detected changes are processed in view of a defined key map to determine which key or keys have been pressed by the user.
