A method for manufacturing a compound refractive lens for focusing X-rays in two dimensions. The first stage is a high input impedance voltage amplifier utilized to amplify the received RF carrier signal from the antenna. In addition, the kiosk may automatically and wirelessly connect the user’s cell phone through the kiosk to a call center representative or emergency service. The drawer assembly further includes a radius limiter secured to the center rail. The node also receives local metrics for the possible actions from the neighbor node. The method further includes generating a deactivation signal and deactivating the corresponding rectifying FET upon a reception of the deactivation signal and deactivating the primary FET after delaying the deactivation signal.
