Patent number: 11419761Abstract: A glaucoma aqueous humor drainage device and a glaucoma aqueous humor drainage method, wherein the opening and closing of a pressure valve is controlled by the change in the pressure in a cavity of the valve. When the pressure in the intraocular pressure exceeds 12 mmHg, the valve is opened, and a drainage tube connected behind the valve drains the aqueous humor to the ocular surface, reducing the patient's discomfort and dry eyes, effectively draining the aqueous humor and avoiding scarring caused by embedding the device via a conjunctival flap and operation failure caused by increase of intraocular pressure caused by generation of filtering blebs.Type: GrantFiled: July 22, 2020Date of Patent: August 23, 2022Assignee: THE EYE HOSPITAL OF WENZHOU MEDICAL UNIVERSITYInventors: Yuanbo Liang, Chengtan Liu, Liang Wen, Yanqian Xie

Patent number: 10069208Abstract: A 5 dBi embedded dual-band WiFi circular polarized 50 mm patch antenna with an SMA(f) connector is described. The antenna features a high efficiency dual-band WiFi 2.4 GHz/5˜6 GHz right hand circular polarization (RHCP). The antennas improve upon the previously developed antennas by simplifying the construction and simplifying the feed, while retaining circular polarization across two widely-separated bands. In order to integrate prior antennas into a system with simple coaxial connections, additional components and devices were required. The antennas simplifies the integration whilst retaining the circular polarization and dual frequency operation. The ratio between the two frequency bands can be adjusted by changing the middle patch and the V-shaped slot size of the top layer. The V-shaped slots improve the axial ratio bandwidth and assist with setting the frequency ration between the two bands.Type: GrantFiled: December 8, 2016Date of Patent: September 4, 2018Assignee: TAOGLAS GROUP HOLDINGS LIMITEDInventors: Max J.
