Introduction

Denis D Shah is a notable inventor based in Union, NJ (US), recognized for his contributions to elevator technology. He holds three patents that showcase his innovative approach to improving elevator systems. His work primarily focuses on enhancing the efficiency and safety of hydraulic elevator operations.

Latest Patents

One of Shah's latest patents is the "Elevator System Monitoring Cold Oil." This invention involves a hydraulic elevator system designed to monitor a cold oil thermostat mounted on a hydraulic oil reservoir. The system prewarms the oil before passenger service by recirculating it through a pumping path that bypasses the hydraulic jack. A control circuit, including a microprocessor, manages all car and corridor functions, ensuring optimal performance and preventing damage to the pump motor windings in case of thermostat failure.

Another significant patent is the "Elevator System Adaptive Time-Based Block Operation." This invention provides an efficient control system for block operation failures. It utilizes a local area network on the traveling cable and distributed electronic control circuits in the car and near the respective floors. Each remote controller, equipped with a microprocessor-based computer circuit, communicates over a multicar-link and local area networks for car and hall calls. This adaptive system ensures that the total building remains serviced despite partial or total communication failures, thereby maintaining operational efficiency.
