Patent number: 11670972Abstract: An electronic device includes a housing coupled to a display window, a battery and a plurality of inductive charging transmit coils coupled to the battery. The plurality of inductive charging coils are positioned within the enclosure to generate an inductive charging region that extends through the display window and across at least a portion of an exterior of the display window. Sensing circuitry is configured to sense a position of a stylus at the display window and a processor is configured to selectively engage and disengage one or more of the plurality of inductive charging transmit coils based on the sensed position of the stylus. The stylus receives power when it is positioned within the inductive charging window.Type: GrantFiled: September 11, 2019Date of Patent: June 6, 2023Assignee: APPLE INC.Inventors: Joel N. Ruscher, Blake R. Marshall, Marco Soldano, Liquan Tan, Todd K. Moyer, Reza Nasiri Mahalati, Victor Luzzato, Wai Man Raymund Kwok

Patent number: 9905345Abstract: Coatings for magnetic materials, such as rare earth magnets, are described. The coatings are designed to reduce or prevent the release of one or both of nickel and cobalt from the coatings or from the underlying magnetic material. The coatings are designed to resist corrosion and release of nickel and cobalt when exposed to moist conditions. The coatings are also designed to be robust enough to withstand damage due to scratch forces. In some embodiments, the coatings include multiple layers of one or of metal and non-metal materials. The coated magnets are well suited for use in the manufacture of wearable consumer products.Type: GrantFiled: March 30, 2016Date of Patent: February 27, 2018Assignee: Apple Inc.Inventors: Katie L. Sassaman, Wai Man Raymund Kwok, Amy Qian, Andrea L. Blakemore

Patent number: 9808829Abstract: Coatings for filling cracks within anodic films formed from, for example, a laser marking process are described. The cracks generally have widths of nanometers in scale and can extend from an external surface of an anodic film to an underlying metal substrate. The coatings fill the cracks to prevent liquid and contaminants from entering the cracks and reaching the metal substrate, thereby preventing corrosion of the underlying metal substrate. The coatings can be hydrophobic such that water is wicked away from the cracks. In some cases, the coatings are fluoropolymer coatings. Methods include spray-on techniques that provide a thin and uniform layer of the coating. The spray-on technique can be configured to spray on a fluoropolymer precursor onto the anodic film such that the fluoropolymer precursor diffuses into and polymerizes into the fluoropolymer coating within the cracks.Type: GrantFiled: September 4, 2015Date of Patent: November 7, 2017Assignee: Apple Inc.Inventors: Jared M. Kole, Ashutosh Y. Shukla, Yi Zhang, Vincent Yan, Wai Man Raymund Kwok
