Abstract: An electronic device can include a battery, a battery charger configured to receive power from an external power source and supply at least one of a charging current or a charging voltage to the battery, and a battery charger controller coupled to charger and configured to control the battery charger. More specifically, the battery charger controller may be configured to control the charger to supply a first AC signal as at least a part of the charging current or charging voltage supplied to the battery, measure a second AC signal associated with the first AC signal, and determine an impedance of the battery at a frequency of interest from the first and second AC signals. The electronic device can also or alternatively include a variable load that may be controlled to supply a first AC signal as at least part of the discharging current or discharging voltage of the battery.

Abstract: In a first implementation, a host determines to pair with a device and transmits biometric data for a user to the device. The device receives the transmitted biometric data and compares such to device biometric data to determine whether or not to pair with the host and/or what data stored by the device to allow the host to access. The host then accesses data of the device to which the device has allowed access. In another implementation, a device determines to pair with a host and transmits biometric data for a user to the host. The host receives the transmitted biometric data and compares such to device biometric data to determine whether or not to pair with the device and/or what data stored by the host to allow the device to access. The device then accesses data of the host to which the host has allowed access.

Abstract: The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system provides a charging circuit for converting an input voltage from a power source into a set of output voltages for charging the battery and powering a low-voltage subsystem and a high-voltage subsystem in the portable electronic device. Upon detecting discharging of the battery in a low-voltage state, the system uses the charging circuit to directly power the low-voltage subsystem from a battery voltage of the battery and up-convert the battery voltage to power the high-voltage subsystem.

Abstract: Eyeglasses may include one or more lenses and control circuitry that adjusts an optical power of the lenses. The control circuitry may be configured to determine a user's prescription and accommodation range during a vision characterization process. The vision characterization process may include adjusting the optical power of the lens until the user indicates that an object viewed through the lens is in focus. A distance sensor may measure the distance to the in-focus object. The control circuitry may calculate the user's prescription based on the optical power of the lens and the distance to the in-focus object. The control circuitry may adjust the optical power automatically or in response to user input. The object viewed through the lens may be an electronic device. The user may control the optical power of the lens and/or indicate when objects are in focus by providing input to the electronic device.
