Patents by Inventor Chonghua Zhou

Chonghua Zhou 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: 7649374
    Abstract: One example of a test board includes first and second communication ports configured for communication with a master device and a DUT, respectively. A bit error rate tester of the test board is arranged for communication with the master device and with the DUT by way of the first and second communication ports, respectively, and the bit error rate tester includes at least one IC whose maximum data rate is temperature sensitive. Finally, the test board includes a temperature control system arranged to control the IC temperature so that a maximum data rate of the IC can be adjusted through the use of thermal effects.
    Type: Grant
    Filed: September 1, 2006
    Date of Patent: January 19, 2010
    Assignee: Finisar Corporation
    Inventors: Alexander Fishman, Denis Y. Lefebvre, Serguei Dorofeev, Dmitri Bannikov, Chonghua Zhou, Robert L. Fennelly

  • Patent number: 6391653
    Abstract: A fluorescent fiber-optic biosensor system using ultrasonic concentration of particles and cells for the detection of Salmonella typhimurium. A biosensor test chamber serves as an ultrasonic standing-wave cell that allows microspheres or cells to be concentrated in parallel layers or in a column along the axis of the cell. A fiber probe along the axis delivers laser excitation to fluorescent-labeled antibodies of Salmonella and collects the fluorescent signal. The Salmonella-antibody complexes are moved acoustically to the axis of the cell, increasing the fluorescent signal. Alternatively, the Salmonella-labelled antibody complexes attach to unlabeled antibodies that have been immobilized on the surface of polystyrene microspheres. This entire structure can be manipulated acoustically and the increase in the fluorescent signal, which can be an order of magnitude, indicates the presence of Salmonella.
