The U.S. Patent and Trademark Office officially released a series of 58 recently granted patents to Apple Inc. today, hours before the iPhone 12 event. In this special report, we briefly cover 3 granted patents related to Urban Canyons, an HMD or AR eyeglass monitoring system and a method for improving the strength of future coverslips for iPhones, other iDevices and Macs. As always, we end this week’s granted patent report with our traditional list of remaining granted patents issued to Apple today.
Eye monitoring sensors
Apple has received patent 10,802,585 covering a future Head-Mounted Display Device (HMD) that includes sensors such as eye monitoring sensor system that collects information about eye activity such as information about saccades and flashes. An HMD can be translated to a VR headset or AR glasses.
By making adjustments to display circuit and image content during periods of suppressed visual sensitivity, potentially visually intrusive changes in displayed images can be hidden from a user of the electronic device. Screen operation adjustments can help reduce burn-in effects, reduce power consumption, and otherwise improve device performance.
Improve coverslip strength
Apple has obtained patent 10,800,141 which generally covers the improvement of coverslips on iDevices. Some traditional glass cover parts may be subject to cracking when subjected to severe shocks, such as when the electronic device falls.
The techniques described in Apple’s assigned patent are generally directed to components which may include a residual internal pressure range in a glass or glass ceramic member. The components described may have improved resistance to cracking and therefore provide improved durability for the components and electronic devices including the components.
Apple’s patent FIG. 2 below shows a simplified example of a cover member for and iPhone; FIG. 11 shows a flow chart of a process for making the cover part; FIG. 12B illustrates a beam of radiation that crystallizes an inner portion of a glass cover to form a glass ceramic.
3D city models with shadow mapping
Many mobile devices, such as smartphones, tablets, and portable devices (such as smart watches), have navigation applications that rely on Global Navigation Satellite System (GNSS) signals. In challenging GNSS signaling environments, as an “urban canyon” with its tall buildings and narrow streets, mobile devices may malfunction in terms of positioning accuracy and accessibility solution. The poor performance worsens in direction and height across the street because GNSS signals with field of view (LOS) are more likely to be blocked by a building or other tall structures.
Apple’s patent designs use 3D city maps and shadow mapping to enhance elevation solutions in urban environments.
Apple’s patent FIG. 1 below illustrates an example of GNSS signaling environment where 3D urban models and shadow mapping are used to improve elevation fixation in urban environments; FIG. 2 is a block diagram of an example of a system for using 3D urban models and shadow mapping to improve elevation solutions in urban environments.
Apple’s patent FIG. 3B above is a perspective view of the example of a 3D candidate position grid.
Apple’s granted patent 10,802,157 is a very detailed patent filing which those in this field can appreciate reading in full here. For the rest of us, it’s clear that Apple is constantly working to allow iDevices to work on performance performance, especially in areas of the Urban Canyons as a downtown area in a large city with many skyscrapers.
