Publication number: 20190223712Abstract: 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.Type: ApplicationFiled: January 24, 2018Publication date: July 25, 2019Inventors: HORNG-JI LAI, LI-PING YU, HSIANG-CHING LEE, TE-LUN MA, CHANG-YUAN FAN, CHEN-HAO KAN

Patent number: 10016884Abstract: A pneumatic nail gun operated in automatic actuation mode includes a gun body, a trigger valve, and a shuttle valve. The gun body defines therein a main chamber and is provided with a forward air conduit and a return air conduit. The forward air conduit provides a path for the pressurized air in the main chamber to force a valve stem of the shuttle valve to conduct a forward movement for a drive stroke. The return air conduit provides a path for the pressurized air in the cylinder to force the valve stem to conduct a return movement after the nail gun has completed the drive stroke. By depressing an actuating bar of the trigger valve a single time, the valve stem can be forced to conduct repeated forward and return movements, and thus the nail gun can conduct repeated drive strokes for stably striking a nail.Type: GrantFiled: January 12, 2015Date of Patent: July 10, 2018Assignee: DE POAN PNEUMATIC CORP.Inventors: I-Tsung Wu, Hai-Lun Ma, Zhen-Liang Liao
