A system and method for synchronizing distributed table buffers is disclosed. By utilizing the existing configuration efficiently, the cost increase due to the system change is minimized. Both antennas are coupled to a receiver via a switch. The source region comprises a second III-nitride epitaxial material. The robot combines the advantages of vacuum-fed robots and pressure-fed robots. Two segment legs, of the large and small segment respectively of such a pair, constitute first and second conductor layers of a first stator slot and have their tip portions mutually connected.
