Marie-Helene Froger, an accomplished inventor based in Chateaugiron, France, has made significant strides in the field of product monitoring and reservoir management. With a remarkable portfolio of ten patents, her work focuses on developing advanced methods and devices that enhance the efficiency of industrial processes, particularly in the printing industry.

Latest Patents

Among her latest innovations is a patent describing a method and device for monitoring the consumption of a product, specifically a printing ink. This technology utilizes a low-pass filter to effectively track the consumption of an electrically conductive product housed within a storage chamber made from electrically non-conductive materials. The process involves the application of an excitation signal to a capacitive arrangement, which generates a measurement signal indicative of the product's quantity. The amplitude of this signal is then filtered and analyzed to provide accurate information on the quantity of product available.

Another significant patent details a method for monitoring the operational state of a reservoir. This invention focuses on reservoirs made from electrically insulating materials that contain conductive products like ink. By connecting the outlet channel to a predetermined potential and employing dual measurement procedures, it ensures real-time monitoring of both the product quantity and the conductivity of the channel. Importantly, the system can trigger abnormality correction procedures or alarms if inconsistencies arise in the monitoring signals, enhancing reliability in operation.
