Introduction

Ketan Lakhera is an inventor based in San Jose, California. His work includes innovations in lighting controllers, with a focus on reducing electromagnetic interference and improving the reliability of sensor inputs. He is associated with Unitx, Inc. and holds 2 patents.

Latest Patents

Lakhera’s latest patents address noise reduction in lighting control systems.

“Lighting controller with noise and signal isolation” describes a controller designed to limit electromagnetic interference through several hardware measures. Its control board uses separate grounds for different circuits, isolating their ground planes instead of connecting them to a shared ground. The design also includes a common-mode filter on the alternating-current input and a high-frequency filter on a digital input line.

“Software filter for noise reduction in lighting controller” describes software that filters input signals so that noise is ignored while valid sensor pulses are processed. The software compares the widths of incoming pulses with an expected pulse width to distinguish legitimate signals from interference.

Career Highlights

Lakhera’s patent work focuses on practical improvements to lighting controller performance. His inventions combine circuit-level isolation and filtering with software-based signal processing to help controllers operate reliably in electrically noisy environments.
