Systems and methods for automatically controlling efficient operation of a plurality of network appliances operatively linked and networked to balance network traffic load across a plurality of network appliances that are selectively enabled. A longitudinal biasing stack overlies the magnetoresistance sensor and includes a longitudinal pinned layer, and a longitudinal pinning layer overlying the longitudinal pinned layer and made of a longitudinal-pinning-layer antiferromagnetic material. For example, a method may include receiving a PLC signal and applying convolutional encoding to the received signal, the convolutional encoding producing an encoded signal. The retrieved configuration information is sent to the wireless enabled field device via at least one wireless communication link to configure the wireless enabled field device. In this way the coil tube sheets combine with other structural members to form the supporting body. Thus, a semiconductor device that can increase data read speed while guaranteeing sufficient data read time from the memory circuit to the data bus is provided.
