A method and device to further remove snow left by a locomotive snowplow while enhancing traction and control of a locomotive or powered car. In one example, the inductance of the matching filter is formed as a microstrip conductor, resulting in a significantly higher quality factor of the inductance and hence an improved linearity and an improved efficiency of the integrated power amplifier. Typically, the plate and the detector are less than about one millimeter apart. The thus produced compressed air foam ensures optimal, economical and environmentally friendly fire-fighting and decontamination. A location is received from a pointing device and one of the plurality of display instances is displayed based on the received location. A lid above and substantially parallel to the top surface of the die forms a portion of the semiconductor circuit package.
