Abstract: The disclosed embodiments provide a system that manages use of a battery (322) in a portable electronic device. During operation, the system provides a charging circuit (330, 334, 336, 340, 342, 344, 346) for converting an input voltage (Vbus) from a power source (302) into a set of output voltages (VHIn, VLO) for charging the battery (322) and powering a low-voltage subsystem (350) and a high-voltage subsystem (352, 354, 356) in the portable electronic device. Upon detecting discharging of the battery (322) 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: In a first implementation, a host (101) determines to pair with a device (102) and transmits(204) biometric data for a user to the device (102). The device (102) receives (303) the transmitted biometric data and compares (304) such to device biometric data to determine whether or not to pair with the host (101) and/or what data stored by the device (102) to allow (305) the host (101) to access. The host (101) then accesses (205) data of the device (102) to which the device (102) has allowed access. In another implementation, a device (102) determines (403) to pair with a host (101) and transmits (405) biometric data for a user to the host (101). The host (101) receives (603) the transmitted biometric data and compares (604) such to device biometric data to determine (605) whether or not to pair with the device (102) and/or what data stored by the host (101) to allow the device (102) to access. The device (102) then accesses (406) data of the host (101) to which the host (101) has allowed access.
