Publication number: 20240059384Abstract: Methods and systems to provide breathing air to underwater divers in response to the divers' respiration at pressures less than 25 psi above atmospheric pressure during inspiration while delivering no or minimal air during exhalation, by controlling the actions of a pump during the time course of breathing. Methods and systems that sense a diver's need for breathing air, determine inhalation demand or exhalation state, and control the operation of a pump which delivers breathing gas to the diver via a tube. An integrated system for the same which incorporates at least an energy source, pump, air tube, breathing aperture, sensor, and logic processor is disclosed.Type: ApplicationFiled: October 31, 2023Publication date: February 22, 2024Applicant: Setaysha Technical Solutions LLCInventor: John Craig COLBORN

Publication number: 20210388778Abstract: A fuel metering system for an internal combustion engine having a fuel injection timing unit to indicate a timepoint during one or more engine strokes, a fuel metering element have a predetermined full stroke volume for metering fuel into an air-fuel mixing location during one or more of the engine strokes, and a fuel metering element controller to control the delivery of fuel by causing the fuel metering element to deliver one of a full stroke volume and a fraction of a full stroke volume to achieve a desired AFR. In some embodiments, power generator circuitry is provided to harvest power from the ICE to power at least one of the fuel injection timing unit, the fuel metering element, and the fuel metering controller.Type: ApplicationFiled: August 29, 2021Publication date: December 16, 2021Applicant: Setaysha Technical Solutions LLCInventor: John Craig COLBORN

Patent number: 11181052Abstract: Methods for controlling an air-to-fuel (AFR) ratio in the metering of fuel to an operating internal combustion engine (ICE) are provided using software-implemented logic controls to enable the determination of one or more of a maximum-power AFR fiducial and a maximum-efficiency AFR fiducial. Control of the fuel delivered to achieve any desired AFT using the fiducial values and/or a known or derived power-AFR curve for the ICE, and pressures of 5 psi or less, without chemical or temperature sensing of the exhaust gas of the ICE.Type: GrantFiled: September 25, 2020Date of Patent: November 23, 2021Assignee: SETAYSHA TECHNICAL SOLUTIONS, LLCInventor: John Craig Colborn
