Latest Patents

One of her latest patents is a helium management control system. This refrigerant management system controls the supply of refrigerant from two or more variable speed and fixed speed compressors to a plurality of cryogenic refrigerators. The system employs a variety of sensors to monitor and regulate the overall refrigerant supply, ensuring that each cryogenic refrigerator receives an appropriate amount of refrigerant. The supply is determined based on the aggregate demand from the refrigerators and a refrigerant correction metric. By adjusting the speed of the variable speed compressors or selectively turning the compressors on or off, the system optimizes refrigerant distribution. If the aggregate demand exceeds the compressors' capacity, the speed of a refrigerator within the system is adjusted accordingly.
