Abstract: An eyelid opener and an eyelid opening and sensing device are provided. The eyelid opener has a housing, two eyelid pushers and one eye positioning unit. The eye positioning unit abuts the surrounding of the eye socket for positioning (e.g. one side of the nasal bridge), and then the sensing process (e.g. eye pressure, eye temperature) of an eyeball sensor is started, ensuring the inspected region remains the same for each measurement. By contacting the user's face, the eyelid opener can be operated by the user independently. The positioning process ensures the eyeball sensor and the eyeball are placed at a fixed distance to prevent the eyeball sensor from physical contacting or hurting the eyeball and to facilitate mounting the eyeball sensor near the eyeball. The two eyelid pushers can avoid unconscious blinking during the sensing process.

Abstract: A magnetic keyswitch assembly includes a movable keycap, a support plate, a magnetic element, a frame and a switch component. The movable keycap includes a pivot and a metal part. The support plate supports the pivot. The magnetic element attracts the metal part, and a direction of a magnetic attractive force between the magnetic element and the metal part is perpendicular to a movement direction of the movable keycap. The frame is for accommodating the magnetic element. The switch component is disposed beneath the movable keycap. The magnetic element attracts the metal part so as to make the switch component in an OFF state as the movable keycap is undepressed. The movable keycap moves downward to trigger the switch component as the movable keycap is depressed to exceed a force threshold.
