Title: Channel estimation for ofdm communication systems
Inventor: KRISHNAN RANGANATHAN
IPC: H04B17/00
Filed: 2003-10-29
Abstract: Techniques to estimate the frequency response of a wireless channel in an OFDM  system. In one method, an initial estimate of the frequency response of the wireless channel is obtained for a first group of subbands based on a pilot transmission received via the subbands in the first group. An estimate of the impulse response of the wireless channel is then derived based on the initial frequency response estimate. An enhanced estimate of the frequency response of the wireless channel is then derived for a second group of subbands based on the impulse response estimate. The first and second groups may each include all or only a subset of the usable subbands. Subband multiplexing may be used to allow simultaneous pilot transmissions by multiple terminals on their associated groups of subbands.

Title: Implantable medical devices using zinc
Inventor: DAKE MICHAEL D
IPC: A61F/
Filed: 2003-10-22
Abstract: Implantable devices (10) using zinc, and methods therefore, provide one or more advantageous effects to a tissue. In one embodiment, at least one zinc- containing component is coupled with a stent via one or more zinc chelators to enhance resistance of the stent to plaque formation and in-stent restenosis. Elastin production may also be enhanced by devices coupled with zinc. Enhanc ed elastin production may be used, for example, to treat a blood vessel in a location at or near an aneurysm. In some embodiments, both elastin productio n and plaque resistance are enhanced. For example, zinc may be applied via a g el or other carrier substance to a venous graft for enhancing elastin and resisting plaque formation. Implantable devices (10) coupled with zinc may provide improved results of medical and surgical procedures involving implantable devices, thus reducing the need for repeat procedures.
