Vishwanath V. Subramaniam 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: 11411227
    Abstract: Disclosed and described herein are systems and methods of energy generation from fabric electrochemistry. An electrical cell is created when electrodes (cathodes and anodes) are ‘printed’ on or otherwise embedded into fabrics to generate DC power when moistened by a conductive bodily liquid such as sweat, wound, fluid, etc. The latter acts, in turn, as the cell's electrolyte. A singular piece of fabric can be configured into multiple cells by dividing regions of the fabric with hydrophobic barriers and having at least one anode-cathode set in each region. Flexible inter-connections between the cells can be used to scale the generated power, per the application requirements.

  • Patent number: 11249068
    Abstract: A non-invasive, continuous, and direct system for detecting the presence of malaria parasites that exploits the paramagnetic properties of hemozoin in red blood cells. An electromagnetic probe (EM probe) is comprised of a dual coaxial coil used to detect iron oxide particles by using sensitive lock-in amplification of detector voltage or phase shift.

  • Publication number: 20090208417
    Abstract: A method for detecting gold or other nanoparticles conjugated to preferential locators commences by contacting tissue suspected of being neoplastic with gold nanoparticle/preferential locator conjugates for a time adequate for the conjugates to bind with the tissue. A beam of gamma photons (such as from, 99mTc) is directed at the conjugate bound tissue to remove electrons from the K-shell or L-shell, for example, of the gold nanoparticles. The removed electrons can be detected for locating neoplastic tissue or X-ray fluorescence corresponding to an electron transitioning from one shell to another shell can be detected, or by detecting resulting X-ray fluorescence corresponding to an electron transitioning from one shell to another shell, such as X-ray fluorescence arising from K-alpha emission corresponding to an electron transitioning from the L shell to the K shell. Additional X-ray fluorescing detecting molecules include Ag, I, Fe, Tc, Zn, Mn, Cr (trivalent).

  • Patent number: 5094915
    Abstract: The invention relates to a method for forming a carbon film on a substrate by irradiating a carbon monoxide-containing gas with an emission from a carbon monoxide laser without irradiating the substrate with the laser emission. The carbon film can be diamond, amorphous carbon, or graphite and the carbon film can be C.sup.13 -enriched or pure C.sup.13 by varying the isotope content of the CO gas in the chamber and/or in the laser.
