Abstract: An electronic device that includes a circuit board and a shield designed to cover the circuit board is disclosed. The shield can provide radio frequency shielding, thermal energy dissipation, and desense mitigation. The shield provides added structural benefits. For example, the thermal assembly can be made with a non-metal material, such as graphite. Further, the thermally assembly may include multiple graphite layers secured by adhesive layers. Additionally, the shield can rely upon adhesives/tapes to adhere to a metal wall located on a perimeter of the circuit board. In this manner, the shield can provide a compliant body that conforms to the position and location of the metal wall, account for tolerance variations in the metal wall, and thus prevent bending of the metal wall, as opposed to using rigid metal bodies. Based on the adhesive properties, the shield requires no holes for fasteners.

Abstract: An electronic device is disclosed. The electronic device may include an enclosure and a transparent cover. The electronic device may include a display assembly. The electronic device may further include an inductive charging unit designed to inductively charge a stylus, or other object suitable for use with the display assembly. The electronic device may further include audio modules, at least some of which are designed to cause resonation of the enclosure to produce acoustical energy in the form of audible sound. Some audio modules produce acoustical energy in relatively low frequencies, while other audio modules produce acoustical energy in relatively high frequencies. The electronic device may further include a vision system designed for facial recognition. The display assembly may include a metal chassis as well as antennae for wireless communication. In order to prevent antennae interference, the metal chassis can be electrically grounded to the enclosure.
