With a total of six patents, Yang has made significant advancements in the field of assistive technology, particularly through his work on magnetic Braille display systems.

Latest Patents

His most notable patents include "Magnetically Programmable Actuators for Tactile Conveyance of Information" and "Electroactive, Actuated Dot Structures." The first patent describes sophisticated magnetic Braille cell actuator structures that include mechanisms for the movement and latching of Braille pins. One of the examples addresses how a Braille pin can remain in a reading position through a small spring force, while a combination of electromagnets and permanent magnets facilitates the latching mechanism. A second example explains how the Braille pin can move between reading and rest positions by leveraging the repulsive and attractive forces between programmable and permanent magnets, allowing for very low power consumption while adhering to standard Braille spacing.

The second patent, "Electroactive, Actuated Dot Structures," presents a system where an actuated dot structure comprises a housing and a pin that moves between two positions. The multimorph in the structure is responsible for displacing the pin while also latching it securely in the second position.
