Title: Lizon Maharjan: Innovator in Propeller Damage Detection and Power Management Systems
Introduction
Lizon Maharjan is a prominent inventor based in Richardson, TX (US), known for her innovative contributions to technology. With a total of six patents to her name, she has made significant strides in the fields of propeller damage detection and power management systems.
Latest Patents
One of her latest patents is the "Sensorless Propeller Damage Detection Systems and Methods." This invention utilizes motor quadrature-axis currents to extract current ripples and fast average current values. The system processes these values to generate normalized root-mean-square (rms) values of the current ripples. By comparing these calculated values to threshold values over time, the system can accurately detect propeller damage without the need for additional sensors or dedicated hardware, thus minimizing false positives and reducing computational costs.
Another notable patent is the "Power Limiting Control for Shared DC Bus Loads." This invention describes systems and methods for monitoring and managing power sharing across multiple loads connected to a shared direct current (DC) bus. It is particularly useful for managing power sharing between multiple propulsion mechanisms in aerial vehicles, such as unmanned aerial vehicles (UAVs). The system establishes current limits based on the DC bus voltage and shape functions for each load, ensuring efficient power management.
