Woon Jong Yoon has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11793695
    Abstract: A multifunction wheelchair, with fixed or folding frame, is described. The multifunction wheelchair is reconfigurable, by a transformation mechanism, between a normal use, ergonomic configuration and a roll-over-toilet configuration. This transformation involves raising the seat of the wheelchair, as needed, to position the wheelchair over the determined height of a toilet, and opening a seat closure mechanism to expose a cutout in the seat for toilet use. This transformation may be at least partially automated. In examples, the multifunction wheelchair is equipped with electronics (e.g., camera, microcontroller) to determine the toilet seat height for making height and/or steering adjustments. The transformation mechanism may be provided as a retrofit kit.

  • Patent number: 10130243
    Abstract: The image-based feedback endoscopy system includes a steering apparatus having a base platform, a pair of servomotors, a rigid tube, and a biasing member. A flexion member has a tether member and a ball screw, the tether member being in communication with the biasing member. The image-based feedback endoscopy system further includes an endoscope having a tip. The endoscope is positioned through the concentric spring such that the tip extends from the biasing member. The endoscope is in communication with the flexion member such that the endoscope is selectively movable by the pair of servomotors selectively controlling the flexion member. The endoscope includes a piezo actuator, a scanning fiber, a lens assembly, and collection fibers. The image-based feedback endoscopy system also includes an image based feedback algorithm, which selectively controls the operation of the pair of servo motors.

  • Patent number: 9946350
    Abstract: Systems and methods may utilize cutaneous feedback for enhanced control of various types of manipulandum. Embodiments of the present invention may include a haptic feedback system comprising: an actuator that exerts force to a user when engaging the actuator that provides cutaneous feedback to the user when using the system. The systems and methods may allow for adjustable and customizable operation of the system to improve the relationship between human and mechanical or virtual devices.

  • Publication number: 20090208143
    Abstract: A scanning fiber endoscope (SFE) disposed at the distal end of a flexible, small diameter imaging probe is inserted through a relatively small opening and into a larger volume, such as the bladder. Actuators disposed adjacent to the distal end of the imaging probe are selectively activated to bend the distal end of the imaging probe to assist in positioning and orienting the SFE at a plurality of points selected to image substantially all of at least a desired portion of the interior surface of the volume. The insertion depth, bending arc, and rotational position of the imaging probe can be manually and/or automatically controlled. The user can inspect the images to determine if a desired portion of the surface has been imaged and can thus ensure that a tumor or other characteristic of the surface is not overlooked due to a failure to image it.
