Patent number: 12127380Abstract: A cooling assembly includes an evaporator containing a primary cooling medium, a passive condenser, and a heat exchanger. When a secondary cooling medium is provided to the heat exchanger, the primary cooling medium in the gas phase switches from being received by the passive condenser to the heat exchanger without operating any valves located between the evaporator and the passive condenser and between the evaporator and the heat exchanger. The primary cooling medium circulates between the evaporator and the passive condenser and between the evaporator and the heat exchanger by natural circulation and gravity without a pump in the flow path of the primary cooling medium between the heat exchanger and the evaporator and between the passive condenser and the evaporator to circulate the primary cooling medium.Type: GrantFiled: November 16, 2023Date of Patent: October 22, 2024Assignee: Munters CorporationInventors: Michael Boucher, Rafael Neuwald, Bryan Keith Dunnavant, John Roberts, Paul A.

Publication number: 20240185189Abstract: A method for ordering the vehicles of a fleet of vehicles according to a maintenance need includes determining a time series for each vehicle in the fleet. The time series includes, for each time step, an instantaneous value of at least one quantity of interest obtained from monitoring events acquired by a system for monitoring the vehicles of the fleet. The time series is analyzed over a predetermined time interval, considering the time series determined for all the vehicles of the fleet, and considering that at each time step, the state of a vehicle is either a “normal” state or an “abnormal” state. An optimal sequence of states over the predetermined time interval can thereby be obtained. A list of the vehicles of the fleet can be ordered according to the properties of bursts detected for each of the vehicles.Type: ApplicationFiled: October 20, 2023Publication date: June 6, 2024Inventors: Andrea STAINO, Nenad MIJATOVIC, Fabien KAY, John ROBERTS, Julien CABOT
