Title: The Innovations of Christophe Jean Jacques Devaucelle
Introduction
Christophe Jean Jacques Devaucelle is a notable inventor based in Boudevilliers, Switzerland. He has made significant contributions to the field of technology, particularly in the area of communication systems. With a total of 4 patents to his name, Devaucelle continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is a Doppler ranging system, which is an extension of the LoRa modulation with an improved ranging mode. In this system, a master and a slave device exchange requests and replies that contain sequences of chirps, which are carefully aligned in time, frequency, and preferably also phase. This alignment allows the master device to ascertain the propagation delay to the slave by demodulating the reply. The request and reply include chirps with different slopes, which permits an unbiased estimation of the Doppler shift.
Another significant patent is for a transmitter, receiver, and method for chirp-modulated radio signals. This invention features a LoRa transmitter and corresponding receiver where the detection sequence in the preamble is phase-modulated. It includes information that encodes the position in the preamble, such as a countdown index. Nodes that wake up to receive a scheduled download can determine how far the end of the detection sequence is and manage their energy consumption accordingly. The phase modulation is also compatible with legacy devices.
