Abstract
Data communication apparatus comprising transmission means adapted to transmit data as the ratio of pairs of frequencies between objects that are moving relative to one another. It is particularly applicable to acoustic data communications at ultrasound frequencies in air.
Claims35
Data communication apparatus comprising a coder and a transmitter, said coder being adapted to code data as the ratio of pairs of frequencies and said transmitter being adapted to transmit said coded data.
(canceled)
A method of data transmission comprising the steps of:
- encoding data as a plurality of signals comprising pairs of frequencies;
- transmitting said frequency pairs;
- receiving each pair of frequencies;
- and
- determining the ratio of said frequencies and decoding data therefrom.
A transmitter adapted to transmit data as the ratio of pairs of frequencies.
A receiver adapted to detect a pair of frequencies, determine the ratio between a pair of frequencies and decode data from said ratio.
