US Patent 7786892 Method for interpretation of a radio-electrical command

A method for the interpretation of a radio-lectrical command for equipment in which the command is interpreted as a function of the emission zone is provided. This is achieved whereby the electromagnetic characteristics of the field generated by the radio-electrical command in the vicinity of a device for reception of radio-electrical commands are determined. The characteristics are compared to determine if the point of the radio-electrical command is located in a near-field or in a far-field zone. A command is then carried out as a function of the command received and as a function of the emission zone of the command. This permits the same command to have two meaning for the equipment.
