Patent number: 11739681Abstract: A far square or diamond architecture engine with tumble flow to support spark-ignited fuel usage. The engine may be provided in a configuration generally suited for swirl flow, compression combustion fuel usage. However, the introduction of a unique, replaceable valve head assembly may be utilized to induce tumble flow within a combustion chamber of the engine. Thus, spark-ignited fuel may be utilized without requiring vast overhaul of the engine to accommodate such fuels. Notably, with the addition of such an assembly, diesel fuel may be replaced with natural gas on large scale equipment without the requirement of impractically burdensome or expensive measures.Type: GrantFiled: September 7, 2021Date of Patent: August 29, 2023Assignee: Southwest Research InstituteInventors: Kevin L. Hoag, Anthony S. Perkins, Ian P. Gilbert, Christopher L. Wray, Marc C Megel, Zainal Abidin

Patent number: 11639682Abstract: A method of providing a passive ignition pre-chamber for an internal combustion engine. The pre-chamber is typically implemented as a cap on the electrode end of a spark plug and encloses a pre-chamber volume in which fuel is mixed with air to form a consistently ignitable mixture. The pre-chamber is passive in the sense that gas exchange with the engine's main combustion chamber is realized by local flow fields near nozzles into the main chamber and by pressure differences between the pre-chamber and the main chamber. The nozzles are sized such that at least one of the nozzles has a larger diameter than the remaining nozzles, as optimized using flow field and pre-chamber turbulence analysis.Type: GrantFiled: February 4, 2022Date of Patent: May 2, 2023Assignee: Southwest Research InstituteInventors: Kevin L. Hoag, Matthew M. Hoffmeyer, Bansal Shah, Zainal Abidin

Publication number: 20200196075Abstract: A manufacturing method for a hearing device, in particular for a hearing aid device, includes preassembling at least one signal processor and at least one microphone in a predetermined position spatially fixed in relation to one another to form an electronic base module. The electronic base module is subsequently inserted into a plastic molding tool and positioned and held in the plastic molding tool by using at least one structural element of the electronic base module, which is in contact with the surroundings in an intended final manufacturing state. Plastic is then introduced into the plastic molding tool to form a main housing for the electronic base module, in which the electronic base module is embedded. A sound channel is kept free for a fluidic connection of the microphone to the surroundings. A hearing device is also provided.Type: ApplicationFiled: December 13, 2019Publication date: June 18, 2020Inventors: RUBAN SUNDARA RAJ THASAPPARAJ, Zainal Abidin Bin Mohd Yahya
