Publication number: 20240113436Abstract: An electronic device may be provided with a phased antenna array that radiates at a frequency greater than 10 GHz. The array may include a first set of dielectric resonator antennas arranged in a first row and a second set of dielectric resonator antennas in a second row offset from the first row. Each dielectric resonator antenna may have dielectric resonating element with a base portion and a stepped portion. The stepped portions of the antennas in the first set may be arranged to be distant from the stepped portions of the antennas in the second set. The antennas in the first set may be arranged to be more distant from an electronic device sidewall than the antennas in the second set. Configured in this manner, the array may exhibit reduced inter-coupling between dielectric resonator antennas in the first set and dielectric resonator antennas in the second set.Type: ApplicationFiled: February 10, 2023Publication date: April 4, 2024Inventors: David Garrido Lopez, Panagiotis Theofanopoulos, Harish Rajagopalan, Subramanian Ramalingam, Forhad Hasnat, Rodney A. Gomez Angulo, Robert Scritzky

Patent number: 11909248Abstract: A device in a wireless power system may be operable with a removable accessory such as a case. The device may transmit or receive wireless power through the case while the electronic device is coupled to the case. The case may have a folio shape with a front cover portion that covers the display of the electronic device. The case may have an embedded ferrimagnetic core that relays magnetic flux during wireless power transfer operations. Magnetic alignment structures in the case may position the ferrimagnetic core in the case in a high magnetic flux density region between the power transmitting device and the power receiving device. The ferrimagnetic core relays the magnetic flux between a transmitting coil in the power transmitting device and a receiving coil in the power receiving device. The ferrimagnetic core may be formed in a front portion, a sidewall, or a rear wall of a case.Type: GrantFiled: February 19, 2021Date of Patent: February 20, 2024Assignee: Apple Inc.Inventors: Zelin Xu, Nan Liu, Zaki Moussaoui, Gianpaolo Lisi, Kunal Bhargava, Madhusudanan Keezhveedi Sampath, Matthew J.

Publication number: 20230352886Abstract: Methods, structures, and apparatus that are able to detect the presence of liquid, moisture, or other contaminants in or on a connector. Examples provide a connector having a dedicated liquid-detect contact that does not have a corresponding contact in a corresponding connector. Examples provide liquid-detect circuitry that can use the liquid-detect contact to determine the presence of a liquid on or in the connector and can perform self-diagnostic tests such as continuity checks and calibration.Type: ApplicationFiled: May 1, 2023Publication date: November 2, 2023Applicant: Apple Inc.Inventors: Tavys Q.

Patent number: 11784511Abstract: A personal electronic device (e.g., a tablet computer) may be configured to wirelessly charge an accessory (e.g., a stylus) through a display face of the device. At least a portion of the display face may be transparent to facilitate display viewing. A wireless charging assembly disposed within the enclosure may include a core having one or more windings disposed thereon, which may be configured to generate a magnetic flux above the display face to couple to the accessory. The core may be a pot core, a modified pot core, or may have another shape, such as a PQ core. The one or more windings may be disposed on one or more posts of a pot core, or additionally or alternatively, may be disposed on another portion of the core. A metallic shield may be disposed about the wireless charging assembly, thereby surrounding multiple sides of the wireless charging assembly.Type: GrantFiled: March 30, 2021Date of Patent: October 10, 2023Assignee: Apple Inc.Inventors: Nan Liu, Madhusudanan Keezhveedi Sampath, Robert Scritzky, Gianpaolo Lisi, Saining Ren, Kunal Bhargava, Zaki Moussaoui, Zelin Xu
