Patents by Inventor Tirunelveli Subramaniam Sriram

Tirunelveli Subramaniam Sriram 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: 8686365
    Abstract: Optical imaging structures and methods are disclosed. One structure may be implemented as an imaging pixel having multiple photodetectors. The photodetectors may detect different wavelengths of incident radiation, and may be operated simultaneously or at separate times. An imager may include an imaging array of pixels of the type described. Methods of operating such structures are also described.
    Type: Grant
    Filed: July 27, 2009
    Date of Patent: April 1, 2014
    Assignee: Infrared Newco, Inc.
    Inventors: Conor S. Rafferty, Anders Ingvar Aberg, Tirunelveli Subramaniam Sriram, Bryan D. Ackland, Clifford A. King
  • Patent number: 8294100
    Abstract: Imagers, pixels, and methods of using the same are disclosed for imaging in various spectra, such as visible, near infrared (IR), and short wavelength IR (SWIR). The imager may have an imaging array having pixels of different types. The different types of pixels may detect different ranges of wavelengths in the IR, or the SWIR, spectra. The pixels may include a filter which blocks some wavelengths of radiation in the IR spectrum while passing other wavelengths. The filter may be formed of a semiconductor material, and therefore may be easily integrated with a CMOS pixel using conventional CMOS processing techniques.
