  • Electronic device
    Patent number: 11960332
    Abstract: An electronic device including a hinge module, a first body, a second body, and a flexible display assembled to the first body and the second body is provided. Each of the first body and the second body is pivoted and slidably connected to the hinge module, and a cover of the hinge module is exposed out of the first body and the second body. The first body and the second body are rotated relatively via the hinge module to bend or flatten the flexible display, when the flexible display is bending from a flat state, a bending portion of the flexible display leans against the cover and pushes the cover away from the first body and the second body.

  • Spherical rotary piezoelectric motor
    Patent number: 8110967
    Abstract: A spherical rotary piezoelectric motor comprises a spherical rotor, a hemispherical stator, and a plurality of piezoelectric actuators. The hemispherical stator comprises an inner surface and an outer surface, wherein the inner surface forms a hemispherical hollow portion which substantially corresponds to the spherical rotor so as to contain a portion of the spherical rotor. The plurality of piezoelectric actuators is arranged on the inner surface (or the outer surface) of the hemispherical stator respectively so as to drive the hemispherical stator. The hemispherical stator generates traveling waves with a resultant elliptical motion, so the spherical rotor can be rotated accordingly with at least one degree of freedom.
