Jules Carpentier took care of the settings of the French engineer Emile Baudot's telegraph system of Posts and Telecommunications.

Thousands of installations "Baudot" were guided workshops to equip Jules Carpentier telegraph networks in France and many foreign countries.

They studied about building new bases induction coils and mercury switches specially designed for the wireless telegraph, and soon established a complete electrical equipment for production of radio waves for downloads powerful capacitors by the age.

Jules Carpentier, always in collaboration with Gustave Ferrie, also created the special thermal wavemeters, frequency meters, ammeters and ohmmeters necessary for the introduction of measurements and calculations in the various parts of the wireless telegraph.

In 1921, the invention of the three-light electrode lamp by American manufacturer DeForest revolutionized the technique of wireless telegraphy and Carpentier was in the process of introducing its use in electrical and radio measuring instruments when his sudden death interrupted the course of his work.

After the premiere public screening held at the Salon Indien del Grand Café on 28 December 1895, was carried out immediately making the first 200 Cinematography demanded by the Lumière brothers.

In 1909, Jules Carpentier workshops, in collaboration with the Lumière brothers, also launched a 35mm camera called "Cinématolabe" but achieved very little success in a market that was already dominated by productions from Pathé and Gaumont.
