Methods and apparatus that seek to increase the diversity seen in wireless communication systems by intelligently implementing a joint multi-dimensional permutation approach. Termination elements in the capacitor assembly, including a porous conductive layer in the capacitor assembly may reduce an amount of vibrational energy transferred from the capacitor to the PCB. , a non-contact color developing system by a simple arrangement, and can output a high-quality image. The controller routes cordless data packets in the cordless signals through the cordless transceiver and amongst the plural cordless terminal devices. In either variation the unsigned values of the N integrations, respectively, may be combined for several data bit time periods.
