Patent number: 9972934Abstract: An electronic device with a port is disclosed. To expel liquid in the port, the port includes modifications to form a capillary pressure gradient with the liquid, causing uneven capillary forces to act on the liquid in the port. For example, the port may include an asymmetric profile with one section having a curved profile and another section having one or more linear profiles that join at an edge. The edge may form a relative higher curved surface as compared to the curved profile. As a result, the capillary pressure gradient may exert a higher capillary pressure in a location associated with the edge, as compared to a capillary pressure along the curved profile. The capillary pressure gradient causes ambient air into the port along the edge, and separates the liquid from the edge, allowing gravity to overcome atmospheric pressure and causing removal of the liquid from the port.Type: GrantFiled: June 2, 2017Date of Patent: May 15, 2018Assignee: Apple Inc.Inventors: Warren Taylor, Jesse A.
