Patents by Inventor Narain Kumar Vijayashanker

Narain Kumar Vijayashanker 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).

  • Input device with integrated deformable electrode structure for force sensing
    Patent number: 9748952
    Abstract: Devices and methods are provided that facilitate improved input device performance. The devices and methods utilize a first electrode and a second electrode disposed on a first substrate and a deformable electrode structure. The deformable electrode structure overlaps the first electrode and the second electrode to define a variable capacitance between the first electrode and the second electrode that changes with the deformation of the deformable electrode structure. The deformable electrode structure comprises a spacing component configured to provide spacing between the deformable electrode structure and the first electrode and the second electrode. Finally, a transmission component is configured such that biasing the transmission component causes the deformable electrode structure to deform and change the variable capacitance. A measurement of the variable capacitance can be used to determine force information regarding the force biasing the transmission component.
