Patent number: 10198089Abstract: An electrode for an input device can be designed to reduce wobble over a range of input device orientations. The electrode can include a spherical portion and a tapered portion. In some examples, the electrode can linearly taper away from the spherical portion. In other examples, the electrode can non-linearly taper away forming an elliptical flare. Additionally or alternatively, the electrode can include a spring-loaded member that can couple the electrode to other circuitry of the input device. Additionally or alternatively, the electrode can include a neck portion coupled to the tapered portion, and part of the neck portion can be shielded. The input device can include a first non-conductive material disposed on part of the spherical portion of the electrode and a second non-conductive material disposed between part of the electrode and the first non-conductive material.Type: GrantFiled: September 8, 2015Date of Patent: February 5, 2019Assignee: Apple Inc.Inventors: Priyanka Bhandari, Blake R. Marshall, Li-Quan Tan, Reza Nasiri Mahalati, Aidan N. Zimmerman, Ryan P. Brooks, Kevin C. Armendariz

Patent number: 10025401Abstract: A ring electrode to determine the orientation of the stylus relative to the surface. The stylus can include a ring electrode configuration which can improve capacitive coupling between the ring electrode and the touch panel. The ring electrode configuration can include a ring electrode and ground ring, and ground plate. By varying the lengths of ring electrode, ground ring, ground plate, and the distance between these elements, the electric field emanating from the ring electrode can be tuned to optimize the capacitive coupling between the ring electrode and surface. In some examples, the ring electrode can include multiple sub-rings. In some examples, the ring electrode can comprise a crown shape including projections, each having a width that tapers to a minimum width along the length of the ring electrode.Type: GrantFiled: September 8, 2015Date of Patent: July 17, 2018Assignee: Apple Inc.Inventors: Priyanka Bhandari, Blake R.

Patent number: 9904379Abstract: A level of wear of a stylus tip can be estimated and in accordance with a determination that the level of wear of the stylus tip exceeds a threshold, the stylus input functionality of an electronic device can be disabled. The threshold can be set such that the stylus can be disabled before the stylus sensing performance degrades to a degree perceptible to a human and/or before exposing internal portions of the stylus that can scratch a touch screen. Additionally or alternatively, a notification can be provided to indicate to a user that the stylus tip should be replaced. In some examples, the estimated level of wear can also be used to provide warning notifications. Stylus tip wear can be estimated, for example, based on a detected total signal strength or based on an estimated total distance traversed by the stylus tip across a surface.Type: GrantFiled: February 29, 2016Date of Patent: February 27, 2018Assignee: Apple Inc.Inventors: Blake R. Marshall, Apexit Shah, Ari Y. Benbasat, Li-Quan Tan, Priyanka Bhandari, Reza Nasiri Mahalati, Sarah M. Bolton
