Title: The Innovations of Christophe Buton
Introduction
Christophe Buton is a notable inventor based in Gemenos, France. He has made significant contributions to the field of contactless communication technology. With a total of 2 patents, Buton's work focuses on enhancing the efficiency and effectiveness of radio-frequency communication systems.
Latest Patents
One of his latest patents is titled "Contactless communication method with negative modulation." This invention concerns a method of radio-frequency communication between a contactless transponder and a reader. In this method, at least one sideband of the carrier frequency is utilized for communicating a response from the transponder by modulating the amplitude of the carrier frequency. The unique aspect of this method is that the modulation applies a level greater than 100%, resulting in negative modulation. Additionally, the invention includes a corresponding communication circuit.
Another significant patent is "Method, circuit and contactless communication device with activated emitting." This activated contactless communication circuit comprises a device for receiving and transmitting a data-carrying electromagnetic field. It features a first circuit resonating with a first antenna for receiving data and a second circuit resonating with a second antenna for transmitting data. Notably, the first and second resonating circuits are separate from each other, and the transmission occurs at a frequency phase-synchronized with the electromagnetic field for reception.
