Brief of Invention: Notch filters find immense applicability in numerous fields, for instance, in biomedical instrumentation, notch filters are used to remove unwanted power line interference and to obtain error free important diagnostics from biomedical signals like ECG, fetal ECG and surface EMG; in body imaging and diagnostics; in the field of automation, for motion control; in GPS and GNSS anti-jamming systems; for estimation and tracking of frequency; and in communication systems in multiple capacities.

Therefore, where ever trimming of a specific frequency is required the instant innovation shall be applicable.

This invention, purely technical, provides a technical solution for how to design a notch filter meeting the two contradictory specifications together. One is the shortest transient (the time filter takes to remove the notch frequency) and other is the highest quality. Overall, the present invention provides an efficient time-varying-pole-radius (TVPR) infinite impulse response (IIR) notch-filter from its complete design to testing and complete development of the filter to solve the above-mentioned technical problem.

Patent: 02

 TITLE OF INVENTION: A GROOVED PROPELLER APPARATUS FOR HIGH THROUGHPUT 

APPLICATION NUMBER:  202411050969  

Date of Filing : 03/07/2024

Patent No. : 600571 

Date of Grant : 27/08/2026

Patentee: Nipun Raj, Hardik Chhabra, Arnav Talwar, Prof. K.P.S. Rana, Prof. Vineet Kumar, Dr. Geetanjali     

Brief of Invention: The present invention relates to a drill-based propeller apparatus for high throughput. The invention relates to an improved drill-based propeller apparatus designed for high-throughput propulsion. The design comprises a propeller body with a cap featuring a drill-like tip with a cutting edge configured to interact with a fluid medium. The cap's top surface includes a plurality of grooves designed to influence airflow across the propeller and vary air density, thereby increasing the thrust generated by the propeller blades. The propeller body has multiple blades mounted at a user-defined angle to a horizontal plane. Additionally, the cap may feature spiral splines on its lateral surface, oriented in the same direction as the blade angle to guide airflow and enhance thrust generation. The apparatus also includes a mounting mechanism for securing and adjusting the blades, allowing for easy replacement and adjustment.

The present disclosure provides a drill-based propeller design for high throughput. The apparatus comprises a propeller body having a cap with a top surface, wherein said cap has a drill-like tip with a cutting edge configured to interact with a fluid medium. The apparatus further comprises a plurality of grooves fabricated on the top surface of the cap, wherein the grooves are configured to influence airflow across the propeller body and vary air density, and wherein the grooves are fabricated on the propeller cap at a user-defined angle. The apparatus further comprises a plurality of propeller blades mounted on the propeller body, wherein the blades are inclined at a user-defined angle to a horizontal plane, and wherein the thrust of the propeller blades is increased by the influenced airflow across the propeller body and the varying air density generated by the grooves inclined toward the blades.
