A time-critical automatic, instantaneous and direct vehicle to vehicle, auto-routing PoliceEmergency Medical Service vehicle, notification and response system that provides interactive and direct communication between a vehicle, non-vehicle, e. A multiplicity of abrasive elements distributed along the groove are in direct contact with the groove inner surface. The decoder may also utilize a single format conversion on data read from an edge memory for bit node processing or check node processing. In another aspect of the invention, wireless communication or computing devices can interact and perform social filtering. The coil includes capacitive elements connecting pairs of conductors. A parallel form of the received data is formed under the control of modified version of the first clock signal.
