This invention provides a cost effective process and new Janus dendrimers where at least two dendrons are attached at the core and where at least two of the dendrons have different functionality. An optical lens is disposed above the package body and includes a hollow dome structure located above and encompassing the lateral extent of the light emitting chip within the well of the package body. After completing a surgical procedure, the separated bone portion of the tibial tubercle is reattached to the remaining portion of the tibial tubercle. The queue-management apparatus then receives a subset of the tags for the device from the host bus adapter and uses the set of tags to queue commands from the host to the device and track the status of the queued commands. The outputs from the first and second digital filters are input to an operational amplifier, and the difference between the restored signals and the ideal restored signals is taken for each sampling of the recording signals.
