A method for performing resource specific channel estimation at a user equipment in a wireless communication system is disclosed. Collector nodes and applications may employ secured, high bandwidth network connections. Still other embodiments of the present invention provide stimulation systems and components for selective stimulation andor neuromodulation of one or more dorsal root ganglia through implantation of an electrode on, in or around a dorsal root ganglia in combination with a pharmacological agent. , having a transverse dimension greater than 1 centimeter, a length greater than 1 millimeter, and a top surface defect density of less than 107 defects cm\u22122. A second insulating layer is then deposited on top of the resistive layer. A unique seating assembly that can be advantageously incorporated into the vehicle taking advantage of the load distributing features of the inventive frame is also disclosed.
