Latest Patents

Marchal’s patent, “Machine for dispensing a controlled amount of a cosmetic composition,” describes a device that transfers cosmetic product from a reservoir through a nozzle into a receptacle. A weighing cell measures the reservoir, and a controller uses the resulting weighing data to determine the difference between the delivered amount and a target weight. The controller then signals an electromechanical member to adjust product delivery. The patent’s distinguishing feature is its use of reinforcement learning to control the dispensing process.

Career Highlights

The patented device applies machine learning to a practical challenge in cosmetic-product dispensing: delivering a specified amount with feedback from a weighing system. Marchal’s association with L’Oréal connects this invention to the cosmetics industry.

Collaborations

Robin Kips and Thibault Chauffier are identified as Marchal’s coworkers. The available information does not specify their roles in the patent or the dispensing technology.

Conclusion

Vincent Marchal’s patent combines weighing feedback, electromechanical dispensing, and reinforcement learning to control the amount of cosmetic product delivered.
