Title: Innovations by John H Hessler in Stair Climbing Technology
Introduction
John H Hessler is an innovative inventor based in Sunnyvale, CA, who has made significant contributions to the field of assistive technology. With a focus on enhancing mobility for individuals with disabilities, Hessler holds 2 patents that showcase his expertise in electronic control systems for stair climbing vehicles.
Latest Patents
Hessler's latest patents include an "Electronic Control System for Stair Climbing Vehicle" and a "Wheelchair Stair Climbing Control System." The electronic control system is designed for stair climbing vehicles, such as wheelchairs, and features front and back sensors that detect stairways or slopes. This system determines whether the incline is acceptable for traversing. If the incline is deemed unsafe, the vehicle is prevented from entering the stairway or slope. Additionally, the system tilts the user's seat to maintain an upright position relative to gravity as the vehicle navigates stairs.
The wheelchair stair climbing control system provides a sensor that detects the angle of an incline before the wheelchair reaches it. A control signal is sent to a motor that tilts the seat to a predetermined minimum safe angle, ensuring that the wheelchair does not roll over if the tilting mechanism fails. This minimum safe angle is influenced by the user's weight and the center of gravity of the wheelchair. If the seat does not achieve this minimum tilt, the wheelchair is prevented from descending the stairs.
