Patent number: 11456669Abstract: Implementations described and claimed herein provide systems and methods for supplying voltage to a load and battery. In one implementation, a first regulated DC-to-DC converter is electrically connected to a first energy source to down convert a first voltage supplied by the first energy source. A load is electrically connected to the first regulated DC-to-DC converter to receive the down converted first voltage. A second regulated DC-to-DC converter is electrically connected to the first regulated DC-to-DC converter to regulate the down converted first voltage to a second voltage. A second power source is electrically connected to the second regulated DC-to-DC converter to charge the second power source using the second voltage, and the second power source is switchably connectable to the load.Type: GrantFiled: August 7, 2020Date of Patent: September 27, 2022Assignee: Apple Inc.Inventors: Jeffrey M. Alves, Peng Wu, Yehonatan Perez, Kisun Lee, Philip Juang

Patent number: 11088567Abstract: Examples of the disclosure are directed to methods of managing power of various modules of an electronic device to prevent the voltage of the battery from falling to an undervoltage lockout (UVLO) threshold. In some examples, software operating on the electronic device or an associated electronic device (e.g., a paired electronic device) may assign power budgets to one or more modules, thereby preventing each module from drawing its maximum current capacity and causing the battery's voltage level to fall to the UVLO threshold. In some examples, a pre-UVLO threshold (i.e., a threshold higher than the UVLO threshold) may be used to modify the states of one or more modules to save power as the voltage of the battery approaches the UVLO threshold, but before the device must be fully powered off.Type: GrantFiled: July 3, 2019Date of Patent: August 10, 2021Assignee: Apple Inc.Inventors: Cyril De La Cropte De Chanterac, David A. Hardell, Matthew L. Semersky, Yehonatan Perez

Patent number: 10998121Abstract: An inductor coil includes a wire which is wound in alternating layers such that the surface area of the wire in each winding viewed from above or below the coil is substantially equal in each half of the coil defined by a line bisecting the center point in each layer. The layers are also wound in a serpentine fashion to balance the capacitance between layers. The substantially equal surface area of wire in each half of a coil layer and in adjacent coil layers results in a balanced capacitance of the coil which, in turn, results in reduced common mode noise.Type: GrantFiled: July 31, 2017Date of Patent: May 4, 2021Assignee: Apple Inc.Inventors: Yehonatan Perez, Makiko K. Brzezinski, Karl Ruben F. Larsson, Christopher S. Graham

Patent number: 10977642Abstract: Methods for operating a portable electronic device to conduct a mobile payment transaction at a merchant terminal are provided. The electronic device may verify that the current user of the device is indeed the authorized owner by requiring the current user to enter a passcode. If the user is able to provide the correct passcode, the device is only partly ready to conduct a mobile payment. In order for the user to fully activate the payment function, the user may have to supply a predetermined payment activation input such as a double button press that notifies the device that the user intends to perform a financial transaction in the immediate future. The device may subsequently activate a payment applet for a predetermined period of time during which the user may hold the device within a field of the merchant terminal to complete a near field communications based mobile payment transaction.Type: GrantFiled: April 25, 2019Date of Patent: April 13, 2021Assignee: Apple Inc.Inventors: Ahmer A. Khan, Gregory B. Novick, Jerrold V. Hauck, Saket R. Vora, Yehonatan Perez

Patent number: 10048715Abstract: A host electronic device may be coupled to an accessory electronic device. During normal operation, the host device may supply the accessory device with power over a power supply line. Back-powering events in which the accessory device delivers power to the host device may be prevented by interposing a protection transistor in the power supply line. A current mirror may be formed using the protection transistor and an additional transistor that produces a sense current proportional to the amount of current that is flowing through the power supply line. A current-to-voltage amplifier may produce a sense voltage that is proportional to the sense current. A bias circuit may be used to bias the sense current through the current mirror. A control circuit may compare the sense voltage to one or more reference voltages and turn off the protection transistor when appropriate to prevent back-powering of the host device.Type: GrantFiled: April 29, 2016Date of Patent: August 14, 2018Assignee: Apple Inc.Inventors: Rajarshi Paul, Yehonatan Perez, Stephen J.
