Patent number: 11920533Abstract: A system includes an aftertreatment system heater of an exhaust aftertreatment system coupled to an engine A controller coupled to the aftertreatment system heater is configured to determine a condition of an exhaust gas from an engine and compare the condition to a predefined threshold. If the condition of the exhaust gas does not meet the predefined threshold, the controller is configured to determine whether an engine operating condition is met for activating a cylinder deactivation operating mode for the engine. If the engine operating condition is met, the controller is configured to operate the engine in the cylinder deactivation operating mode by deactivating a cylinder of a plurality of cylinders. If the engine operating condition is not met, the controller is configured to activate the aftertreatment system heater to heat the exhaust gas.Type: GrantFiled: May 27, 2020Date of Patent: March 5, 2024Assignees: Cummins Inc., Tula Technology, Inc.Inventors: Jennifer Kay Light-Holets, J.

Publication number: 20230255389Abstract: A liquid heating appliance including a reservoir including a first and second chambers and a heating arrangement is provided. A mode valve is arranged to selectively allow liquid to flow between the first and second chambers. The appliance operates in a first mode in which the mode valve is closed and only liquid in the first chamber is heated and a second mode in which the mode valve is open and liquid in the first and second chambers is heated. A dispense outlet is moveable between a dispensing position and a non-dispensing position. The dispense outlet is mechanically coupled to the mode valve such that when the dispense outlet is moved into the dispense position, the mechanical coupling closes the mode valve and when the dispense outlet is moved into the non-dispensing position, the mechanical coupling opens the valve.Type: ApplicationFiled: July 9, 2021Publication date: August 17, 2023Inventors: Colin Peter Moughton, Stephen John Donlon, Christopher Kay, Jacob Alexander John Hewins

Patent number: 7162878Abstract: Disclosed is an efficient refrigeration apparatus that provides refrigerant based energy storage and cooling. When connected to a condensing unit, the system has the ability to store energy capacity during one time period and provide cooling from the stored energy during a second time period. The system requires minimal energy to operate during either time period, and only a fraction of the energy required to operate the system during the first time period is required to operate the system during the second time period using an optional refrigerant pump.Type: GrantFiled: October 15, 2004Date of Patent: January 16, 2007Assignee: Ice Energy, LLCInventors: Ramachandran Narayanamurthy, Robert K.
