Patents by Inventor Shah A. Chowdhury

Shah A. Chowdhury 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).

  • Patent number: 11092564
    Abstract: A system and method for Displacement Current Phase Tomography. The present system invention obtains a linear relationship between mutual displacement current from a sensor (output current of the measuring electrode terminals) and the area (or volume) of an object to be imaged in the imaging domain. The system uses capacitance sensors and utilizes the phase of the measured current, in addition to the amplitude, to reconstruct an image.
    Type: Grant

  • Patent number: 8913491
    Abstract: Mobile network services are performed in an appliance in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. The appliance in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. The appliance has defined interfaces and defined commands on each interface that allow performing all needed functions on the appliance without revealing details regarding the hardware and software used to implement the appliance. The appliance includes overload detection and handling within the appliance. This appliance architecture allows performing new mobile network services at the edge of a mobile data network within the infrastructure of an existing mobile data network.
