Cilia-like micro surface actuators are applied to fins of a heat sink to improve heat dissipation. The method continues by creating light dose extension implants in the semiconductor material by bombarding the device structure with ions at a non-tilted angle relative to an exposed surface of the semiconductor material. The adaptor may include other features for preventing unauthorized use of protected content, for example authenticating the source of a content signal before providing an output audio or video signal, encrypting the output video signal, responding to commands to renew or revoke cryptographic keysets, and embedding forensic tracking information in an audio or video signal. The fascia includes a horizontal portion. The releasable attachment device has a retainer and an operator for moving the retainer from an engaged position, in engagement with the bezel for retaining the bezel on the case body, to a disengaged position, disengaged from the bezel, for releasing the bezel.
