Patent number: 11615257Abstract: Disclosed is a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to communicate wirelessly with an implant device associated with a proprietary system provided by a first entity. An external device, that may not be associated with said first entity, is provided and is configured to be calibrated to communicate with the implant device that is located within a patient. The external device may be used in place of an existing reader device that was initially calibrated to communicate with the implant device prior to the implant device being placed within the patient. The external device may be particularly useful for implant devices that communicate wirelessly with external devices where said implant devices are intended to be located within the human body on a permanent or indefinite duration of time.Type: GrantFiled: January 4, 2021Date of Patent: March 28, 2023Assignee: ENDOTRONIX, INC.Inventors: Nicholas Chronos, Michael L. Nagy, Douglas A. Nielsen, Balamurugan Sundaram, Suresh Sundaram

Patent number: 10801430Abstract: Air to fuel ratio management comprises sensing a power output request for the engine and determining a fuel-efficient air to fuel ratio. A current air to fuel ratio is sensed in one or both of an intake manifold and an exhaust manifold connected to the engine. An air to fuel ratio adjustment is determined based on the fuel-efficient air to fuel ratio and based on the current air to fuel ratio. An in-cylinder exhaust gas recirculation technique is selected. The in-cylinder exhaust gas recirculation technique adjusts an oxygen and particulate content of exhaust gas resulting from combustion. A number of cylinders of the multiple-cylinder engine are selected to implement the in-cylinder exhaust gas recirculation technique. The intake valves and the exhaust valves are controlled to adjust the oxygen and particulate content of the exhaust gas by applying a second compression stroke of the respective reciprocating pistons to the exhaust gas.Type: GrantFiled: January 19, 2017Date of Patent: October 13, 2020Assignee: Eaton Intelligent Power LimitedInventors: James E.
