Li Houliang 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).

  • Method for measuring pressure on the substrate of spin formed catalytic converter
    Patent number: 6732429
    Abstract: The present invention is generally directed towards a catalytic converter installed in the motor vehicles. More specifically to a method of measuring the pressure on the substrate as the catalytic converter is subject to the spin forming process. A pressure-measuring device such as a sensor is contact with the substrate. In order to transfer data from the rotating catalytic converter to a stationary object, a slip ring device is connected to the pressure-measuring sensor.
    Type: Grant
