An MnZn ferrite includes base components of 44. The system has associated multiple receiving antennas. In one embodiment, the second die has a recessed edge along the perimeter of the bottom surface to provide clearance for a bonding element extending from bond pads on the first die to pads on the substrate, thus eliminating the need for a spacer between the two dies. The inflatable assembly can be operatively associated with a vacuum device to allow for selective removal of gas from the inflatable assembly. The processor can clip the audio signal from the start time to the end time to produce a portion of the audio signal.
