Title: Joseph J Barna: Innovator in Elevator Rescue Systems
Introduction
Joseph J Barna is a notable inventor based in Trumbull, CT (US). He has made significant contributions to the field of elevator safety, holding a total of 3 patents. His work focuses on innovative solutions for rescuing trapped elevator passengers, enhancing safety and efficiency in emergency situations.
Latest Patents
One of Barna's latest patents is a system for the remote rescue of trapped elevator passengers. This elevator rescue system provides rescue signals from a remote control station, which typically monitors multiple elevators. The system operates a release mechanism, such as the brake, allowing the elevator to move to an appropriate door zone. The rescue signal is initiated when the remote control station receives an alert from the elevator monitoring system indicating that passengers may be trapped. The remote control station first ensures that it is safe to move the elevator before commanding the operation of the elevator component that allows movement.
Another significant patent is the elevator rescue system that includes a backup power source. This system features a manually-operated rescue enable switch that allows electrical power to be transmitted to the motor brake coil of the elevator car during a rescue operation. A speed detector measures the elevator car's speed and generates a corresponding speed control signal. An overspeed detection circuit ensures that electrical power is transmitted to the motor brake coil only when the speed control signal is below a predetermined value, enhancing the safety of the rescue operation.
