摘要 <p>The driver's commands are converted into a series of binary sequences, each including synchronisation bits occupied by a periodic binary signal and data bits conveying the means of the commands in two-phase binary form. The modulated carrier wave is received and the binary sequences are restored for conversion into appropriate electrical signals. - The generally portable transmitter (E) has input switches, cursors or pushbuttons (PC) and logic (LS) for regrouping and channelling only commands which are suitable for simultaneous transmission in accordance with pre-established priority rules. 04 the receiver (R) a binary decoder (DB) is followed by processing logic (LS') and a controlling output stage (S).</p>
