Patents by Inventor Patanjali V. PARIMI

Patanjali V. PARIMI 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: 10944179
    Abstract: Orbital angular momentum (OAM) communications systems provide an additional degree of freedom to the electromagnetic waves that travel between the transmission and receiving stations, thereby enabling a dramatic increase in data transmission rates. The present invention provides a design for a very low reflectivity flat spiral phase plate that generates OAM modes and a method of making the same. The design incorporates variable sizes of perforated unit cells and may include matched layers to provide improved impedance matching, and the flat disc shape makes the phase plate compact and easy to install. The OAM phase plate can be designed to operate at frequencies from a few 100s KHz to ultraviolet frequencies and is capable of providing one or more OAM modes at the operational frequencies, irrespective of polarization. In a preferred embodiment, the OAM phase plate is designed for operation at about 30 GHz frequency, with 20 GHz bandwidth.

  • Patent number: 10819152
    Abstract: The present application provides a wireless power transfer system including a transmitter and at least one receiver, and also provides transmitters and receivers for such systems. The transmitter includes a driver coil and a transmitter coil magnetically coupled to each other and arranged along a plane, the driver coil and the transmitter coil being tuned to resonate at differing frequencies. The receiver includes a load coil and a receiver coil magnetically coupled to each other and arranged along a plane, the load coil and the receiver coil being tuned to resonate at differing frequencies. The driver coil and the transmitter coil of the transmitter, and the load and the transmitter coil of the receiver are strongly magnetically coupled to each other. The transmitter and the receiver are magnetically coupled to each to effectuate wireless power transfer from the transmitter to the receiver.

  • Publication number: 20190308514
    Abstract: The present invention comprises a wireless charging station, configured to charge remote controlled and autonomous vehicles and robots, including one or more charging pods, wherein each pod has at least two panels and at least two wireless power transmitters (WPTs) affixed to at least two of the panels, wherein the WPTs are configured to deliver power wirelessly to at least two wireless power receivers (WPRs), associated with a remote controlled vehicle, an autonomous unmanned vehicle or a robot. The present invention further comprises a method to charge a robot or vehicle at a distance from a wireless power transmitter (WPT), the method comprising: detecting a first WPR located a first distance from a first WPT and a second WPR located a second distance from a second WPT, and transmitting power from the WPTs to the WPRs to charge the robot or vehicle.
