Patents by Inventor Vishal Gajendrarao Yadav

Vishal Gajendrarao Yadav 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: 12076617
    Abstract: A nonlinear radar system includes a first antenna configured to generate and emit an incident signal having a first frequency, a transponder tag attached to an existing portable object, wherein the transponder tag includes an electromagnetic nonlinear element configured to be detected by the incident signal. Upon being detected by the incident signal, the transponder tag is configured to transmit a reflected return harmonic signal having a second frequency different from the first frequency, wherein the reflected return harmonic signal is an on-off keying (OOK) signal. A second antenna is configured to receive the reflected return harmonic signal having the second frequency. The transponder tag includes a conductive layer in electrical communication with the electromagnetic nonlinear element including a Schottky diode.

  • Patent number: 11892537
    Abstract: A nonlinear radar system includes a handheld unit including a display screen, a first antenna configured to generate and emit an incident signal having a first frequency, and a second antenna configured to receive a reflected return harmonic signal having a second frequency, as well as a transponder tag is attached to an existing golf ball. Such a transponder tag is in communication with and responsive to the handheld unit, and includes an electromagnetic nonlinear element configured to be detected by the incident signal without the need for a line of sight. Upon being detected by the incident signal, the transponder tag is configured to transmit the reflected return harmonic signal having the second frequency different from the first frequency. The transponder tag is passive and does not require a power source other than incident radiation.
