Patents by Inventor John Ruf

John Ruf 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).

  • Flow control assembly having localized non- volatile memory
    Patent number: 12650687
    Abstract: An apparatus for controlling fluid flow and in particular fluid flow through a microfluidic multi-port control valve assembly of a High Pressure Liquid Chromatography (HPLC) unit. The flow control apparatus has a localized data repository for storing local valve position data and cumulative wear indications of components of the apparatus. The stored information travels with the apparatus allowing for more reliable predictive failure of components of the apparatus and translation of local valve position data for compatibility with host valve information. The translated valve position data enables determination of whether valve motion is acceptable and complete.

  • Fluid degassing system with reduced pressure pulsatility
    Patent number: 11504650
    Abstract: The pressure fluctuations in a fluid degassing system may be diminished by independently controlling the intake phase and the exhaust phase of an evacuation pump. The speed of the pump's drive element may be modulated at least during the intake phase to more closely align with a pressure set point in a degassing module.

  • Flow control assembly having localized non-volatile memory
    Patent number: 11454962
    Abstract: An apparatus for controlling fluid flow, and in particular fluid flow through a microfluidic multi-port control valve assembly of a High Pressure Liquid Chromatography (HPLC) unit includes a localized data repository for storing cumulative wear indications of components of the apparatus. The stored information may travel with the apparatus to enable predictive failure of components of the apparatus.
