Systems and methods for editing digital audio data are provided. The media processor transmits a request to a remote server including the second key; the server returns first additional content and control code associated with the second key. A transistor funnel limits leakage currents from a portion of the plurality of transistors to a single transistor of the transistor funnel. At the receiver, conventional polarization shift keying receiver can be used to restore original binary data stream. In use, waste introduced into the hopper deposits on the interior surface when the packer is retracted and is swept by the packer mechanism through the aperture during an extension stroke of the packer. When combined with a suitable activator, these compounds show activity in the polymerization of olefins, such as ethylene and propylene.
