Patents by Inventor Randall Roy Hume

Randall Roy Hume 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-sensing device and method for fabrication
    Publication number: 20040211254
    Abstract: A gaseous flow sensor that utilizes non-platinum resistive sensing elements and a method for fabricating such sensor are disclosed. The gaseous flow sensor is constructed by an insulating substrate; a reference resistor formed on the substrate and disposed in the gaseous flow at an ambient temperature without heating; a flow-sensing resistor formed on the substrate disposed in the gaseous flow that is heated to a temperature higher than the ambient temperature; and an electrical circuit in electrical communication with the reference resistor and the flow-sensing resistor for feeding a current into the flow-sensing resistor in order to keep the two resistors at the same temperature during the operation of the gaseous flow sensor.
    Type: Application
