Abstract: A distance measuring receiver system and method for determining the distance of a receiving station from a transmitting station, which provides the distance information by the reception and processing of a pair of signals (preferably continuous wave carrier) transmitted by the transmitting station. The filter subsystem 106 supplies the upper signal to the first channel 501 and the lower signal to the second channel 502 of a lane expansion subsystem 108, which produces a plurality of difference frequency signals 113, 115, 117, 119 (of preselected multiples) in accordance with the upper and lower signals. A reference subsystem 112 in accordance with the oscillator signal 121 supplies a plurality of reference signals 127, 129, 131, 133 (having frequencies equal to the frequencies corresponding to difference frequency signals).

Abstract: A modified two-stroke or four-stroke internal combustion engine comprises means and a method for increasing the power output of an internal combustion engine by providing a non-combustible fluid to the engine. The engine transfers thermal energy of combustion to the non-combustible fluid, thereby causing expansion of the fluid, and includes means for converting expansion of the fluid to mechanical power.
