An apparatus includes: a process chamber for treating a substrate; a susceptor in the process chamber; a supporting frame over the susceptor; and at least one wire connected to the supporting frame. In at least one embodiment, an access terminal periodically polls at least one network device via the access point for synchronization data according to a first data-synchronization interval. The repository of consumer data comprises a plurality of data items regarding consumers, wherein at least some information in the consumer data is not in the trade data and at least some information in the trade data is not in the consumer data. The electronic and actuator assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating actuator element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure. The first and second output signals are combined to generate an estimate of the desired satellite uplink signal. One or more candidate antipodal point pairs of the convex hull are determined.
