  • STAIR NAVIGATION ASSIST SYSTEM
    Publication number: 20240099924
    Abstract: A system for assisting a user with navigating a set of stairs includes a pulley system positioned adjacent to the stairs, the pulley system including a first pulley, a second pulley, and an elongated member coupled to and looped around the first pulley and the second pulley. The system further includes a motor coupled to the first pulley, a sensing assembly operatively coupled to the pulley system, the sensing assembly being structured and configured to sense that a force is being applied to or that is about to be applied to the elongated member by the user, and a controller coupled to the motor and the sensing assembly. The controller is structured and configured to, responsive to the sensing assembly sensing the force, turn the motor on to drive the first pulley.

  • Motorized robotic walker guided by an image processing system for human walking assistance
    Patent number: 11396314
    Abstract: A motorized robotic walker is capable of moving automatically with the user through an algorithmic process using a 3D camera image processing system. The image processing system can measure relative motion of the user versus the robotic walker and a microprocessor can generate PWM signal to drive motors of the robotic walker so that the robotic walker can follow the user's motion automatically and provide assistance if needed.
