A wireless system is provided which comprises a test and control device, and a power distribution device. The medical devices comprise a therapeutic agent and a polymeric release region that controls the release of the therapeutic agent upon administration to a patient. A third embodiment of a semiconductor package includes a leadframe having a lead with a first level downset lead extension, a quad flat nonleaded package connected to the first level downset lead extension, and a first wirebondable die attached to a top or bottom surface of the quad flat nonleaded package. The DCU imparts an angular dispersion, group-velocity dispersion and a spatial chirp to a beam propagating in the cavity.
