Abstract: A portable electronic device for providing real-time interaction between a user performing an exercise routine and a virtual competitor. Some embodiments of the portable electronic device may include a sensor for receiving a plurality of user performance metrics associated with the user, a processor for generating a comparison between the plurality of user performance metrics and a competitor workout file associated with the virtual competitor, and a display for displaying a summary of the comparison in real-time.

Abstract: A method and system is disclosed for facilitating miniaturization of an electronic device by efficiently utilizing available space. Specifically, in an exemplary embodiment, there is provided an electronic device comprising a substrate, a cavity formed in the substrate, and a bridge coupled to the substrate such that it spans the cavity. Further, the device may include a semiconductor device coupled to the bridge such that the semiconductor device is positioned within the cavity. In some embodiments, the bridge may include a tape automated bonding (TAB) tape having various layers, including a layer configured to provide electromagnetic shielding.
