Latest Patents

Ding is credited with 1 patent: “Electronic Devices with Compound Planetary Gearboxes.” The patent describes head-mounted electronic devices with left-eye and right-eye optical modules that can move relative to one another to accommodate users’ different interpupillary distances.

The adjustment system may use motors, compound planetary gearboxes, and lead screws to reposition the optical modules. The gearbox design uses planet gears mounted on common shafts, with carriers that support the gears and drive the lead screws. Smaller second planet gears mesh with teeth on a ring gear, helping achieve a high reduction ratio. This arrangement is intended to provide sufficient torque while keeping the actuators compact.

Career Highlights

Ding’s listed patent reflects work on mechanical systems for wearable electronics. Its gearbox configuration addresses the practical challenge of moving optical components precisely within a compact head-mounted device.
