Patent number: 11983370Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.Type: GrantFiled: July 24, 2020Date of Patent: May 14, 2024Assignee: Apple Inc.Inventors: Supratik Datta, Karan Jain, Zhiyuan Sun, Ho Hyung Lee, Da Yu, Wei Lin, Nathan K.

Patent number: 5486117Abstract: A locking system is provided for an electrical connector assembly which includes first and second electrical connectors. The first connector includes a housing having a mating face and a latching surface facing in a direction generally opposite the mating face. The second connector includes a housing having a complementary mating face for interfacing with the mating face of the first connector and a metal spring latch arm cantilevered from the second connector, with a hook portion for latchingly engaging the latching surface of the first connector. The latch arm is located for manual deflection to move the hook portion out of engagement with the latching surface to allow unmating of the connectors with minimal force. The hook portion is radiused therefore deflecting the latch arm in response to an unmating force applied directly to the connectors, i.e. without manual deflection of the latch arm, that is greater than the minimal force.Type: GrantFiled: August 9, 1994Date of Patent: January 23, 1996Assignee: Molex IncorporatedInventor: Wei-Sun Chang
