A system for diagnosing a vehicle terminal includes a WiFi dongle coupled to an external connection terminal of a vehicle to connect wireless communication between a vehicle diagnosis device and the vehicle terminal. A fabric is bonded to the surface of a padding material on one side so as to form a reversible toe pad. The dominant and recessive signal levels form a series of bits organized into messages by the nodes. The reactor of the invention may process a single wafer or a plurality of wafers at the same time. Each toboggan has a boss that has an upper round portion and base rounded portions. The correlator temporally identifies an event that occurs to indicate a target-reflection pulse within the combined signal.
