Andrew Morgan Myer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Diaphragm pump system having re-priming capabilities
    Patent number: 9441518
    Abstract: An example system includes a diaphragm pump having a suction port and a discharge port, a urea suction line fluidly coupling a urea supply to the suction port, and a urea discharge line fluidly coupled to the discharge port. A recirculation line fluidly couples the urea discharge line to the urea suction line, and has a flow regulator operationally coupled thereto. A controller is configured to interpret a prime loss condition of the diaphragm pump, and to provide a flow regulator command in response to the prime loss condition.

  • Ammonia generation system for an SCR system
    Patent number: 9353665
    Abstract: A system including a reductant source storing reductant, an ammonia generation system configured to generate gaseous ammonia via cavitation, and a gaseous ammonia delivery device in fluid communication with the ammonia generation system and an exhaust system. The system may selectively activate the ammonia generation system responsive to a detected temperature of an exhaust gas of an exhaust system being equal to or below a predetermined value. The ammonia generation system may utilize ultrasonic cavitation or laser cavitation to generate gaseous ammonia to be delivered to the exhaust system responsive to the temperature of the exhaust gas of the exhaust system being equal to or below the predetermined value. If the temperature of the exhaust gas of the exhaust system above the predetermined value, a dosing module to dose reductant to the exhaust system may be activated.
