Apple Granted Two Major Apple Pencil Patents for iPad Pro

1 Cover Apple Granted Patent Report for Apple Pencil July 17  2018

 

The U.S. Patent and Trademark Office officially published a series of 40 newly granted patents for Apple Inc. today. In this particular report we cover two major patents relating to Apple Pencil, a high-precision stylus that is one of the very best on the market today that offers reduced latency over conventional stylus input systems.

 

Granted Patent: Apple Pencil

 

Apple's newly granted patent covers their invention relating to a high-precision stylus (Apple Pencil) operable with a touch screen. This is one of the most extensive patents on the Apple Pencil that covers the following detailed segments:

 

  • User Input Systems Incorporating a Stylus
  • Electronic Devices Configured to Receive Input from a Stylus
  • Locating the Stylus
  • Angular Position of the Stylus
  • Detection of Force Applied by the Stylus
  • General Operation of a User Input System
  • General Operation of a Stylus of a User Input System
  • General Operation of an Electronic Device of a User Input System
  • Coordination Between the Stylus and the Electronic Device
  • Main Controller Subsystem of the Stylus
  • Power Subsystem of the Stylus
  • Component Layout of the Stylus

 

2 Apple Pencil Patent july 2018

Apple's patent FIG. 1A depicts an electronic device with a touch-sensitive display (an "input surface") that is configured to receive input from a stylus; FIG. 3D depicts the stylus assembled, presenting a barrel, a nib, and a blind cap of the stylus in phantom, while depicting an internal chassis of the stylus as partially transparent; FIG. 11E depicts a stylus incorporating a power connector (Smart Connector) that is configured to electrically couple to an external surface of an electronic device. Apple has yet to implement this superior power feature.

 

Apple notes in one part of their patent that "the user input system embodiments described herein can operate with reduced latency over conventional stylus input systems." This is one of the advantages of Apple Pencil.

 

Apple's granted patent 10,025,404 was originally filed in Q3 2016 and published today by the US Patent and Trademark Office. There are 8 inventors listed on the patent. One of the lead engineers for Apple Pencil was Aidan Zimmerman and the information below was listed in his LinkedIn page.

Granted Patent: Active Stylus Ring Electrode

 

Apple's newly granted patent covers their invention relating to input devices for use with touch-sensitive devices and, more specifically, to the design of a ring electrode of an active stylus.

 

The invention further relates to detection of an orientation, e.g., the azimuth angle and tilt angle, of a stylus relative to a surface. In an example, the orientation of a stylus relative to a contacting surface, e.g., a touch panel can be detected by detecting a capacitance at one or more locations on the stylus relative to the surface, and then using the capacitance(s) to determine the orientation of the stylus relative to the surface.

 

In some examples, the stylus can include a ring electrode configuration which can improve capacitive coupling between the ring electrode (used for orientation detection) and the touch panel.

 

Apple's patent FIGS. 8A and 8B illustrate an azimuth angle and a tilt angle, respectively, for an example stylus and example touch-sensitive device; FIG. 9C illustrates an example stylus including a cylindrical ring electrode configured to have a more uniform electric field coupling; FIGS. 10A illustrates a perspective view of a ring electrode configuration configured to have a more uniform electric field coupling.
