Title: Innovations of Karma Vir Sangwan

Introduction

Karma Vir Sangwan is an accomplished inventor based in East Amherst, NY (US). She holds an impressive portfolio of 16 patents, showcasing her expertise in the field of vehicle climate control systems and refrigerant compressors. Her innovative contributions have significantly advanced technology in these areas.

Latest Patents

One of her latest patents is a humidity-based defog control method for a vehicle climate control system. This invention develops a fog index based on the relative humidity at or near the inner surface of the windshield. It uses this fog index to variably override the normal control settings, ensuring optimal visibility for drivers. The relative humidity is combined with a pair of humidity thresholds to form a dimensionless fog index. Fog index values within a predetermined range are applied to a variable path function for transitioning between existing control settings and those that maximize defogging.

Another notable patent is the integrated control valve for a variable capacity compressor. This invention includes an integral pressure sensor that continuously measures the refrigerant discharge pressure. The plunger of the control valve is positioned by pneumatic and electric control elements to regulate the refrigerant suction pressure. The design ensures that the pressure sensor is continuously exposed to the discharge pressure, allowing for precise control and efficiency in refrigerant management.
