Abstract: A method and communications device for providing antenna tuning to compensate for antenna de-tuning caused by a presence of an object detected using an antenna element within a capacitive touch and proximity sensor (CTPS). The CTPS propagates object detection signals associated with a detected object to a detection IC. An object detection and antenna tuning (ODAT) logic uses object detection signal information to generate tuning control signals to trigger compensatory antenna tuning, based on pre-established mappings of object detection signal data and antenna tuning states. The tuning control signals indicate at least one of (a) a level of compensatory antenna impedance tuning and (b) an amount of compensatory antenna length adjustment. In response to generating the tuning control signals, the ODAT logic triggers the propagation of the tuning control signals to the antenna matching and control circuit to provide the corresponding antenna tuning.

Abstract: Disclosed is a lid having a perimeter, a pre-scored line that defines a rupturable tear panel, and a pull tab rotatably and pivotally attached to the lid. The pull tab is rotatable between a closed position in which the entire length of the pull tab is contained within the perimeter of the lid, and an opening position in which the handle portion of the pull tab extends beyond the perimeter of the lid. In the opening position, the lid-piercing portion of the pull tab is juxtaposed with the pre-scored panel and is configured to pierce the rupturable tear panel when the handle portion of the pull tab is lifted.
