Abstract

This device transmits data in asymmetrical pulse form so as to penetrate noise environments. Such noise is symmetrical and, hence, easily distinguishable to a wave-peak asymmetry detector AD.

Asymmetry Communication

This device transmits data in asymmetrical pulse form so as to penetrate noise environments. Such noise is symmetrical and, hence, easily distinguishable to a wave-peak asymmetry detector AD.

The upper drawing shows a transmitting unit in the form of an asymmetry wave generator AG, possibly in conjunction with transmitting means T, so as to generate a wave or plurality of waves having asymmetrical characteristics. Communication is established when these waves are detected by receiver R. This sends the transmitted asymmetrical wave to an asymmetry detector AD. Here the degree of asymmetry is measured and displayed at D. Generators AG for the asymmetrical waves can be any source operable according to an unequal peak compression or phase modulation of an electrical wave.

Also suitable are acoustic sources for generating asymmetrical sounds, for instance, such as mechanical thumpers employed in Sonar systems or geophysical sounding. These thumpers can be used in tandem to generate pulses of positive and negative asymmetry to establish a homing type glide path. Its location can be found by receiver R and asymmetry detector AD according to null balance of negative and positive thump pulses. Such a thumper system is shown in the lower drawing. The asymmetry generator AG' has a pair of positive and negative thumpers, T+ and T. These generate waves having positive and negative asymmetry respectively. The receiving mechanism comprises a hydrophone H...
