  • Patent number: 8184969
    Abstract: An electronic device and method for power management in an electronic device is provided. In an embodiment, the electronic device includes the functionality of a personal digital assistant, wireless email paging and a camera with a flash that is operated via self-contained power supply in the form of a battery. The device also includes a supervisor circuit which causes the device to enter sleep mode, or disables the device or certain features of the device, if the battery level falls below a certain threshold. A method in accordance with an embodiment performs, in response to a request to fire the flash, a pre-flash test which is selected so as to not trip the supervisor circuit. The battery level is examined after the pre-flash test. If the battery level meets certain criteria, the full flash is permitted to proceed, else the full flash is not permitted to proceed.

  • Publication number: 20120026389
    Abstract: A method and apparatus for maintaining a maximum sustained flash current over the whole length of a flash using a programmable current drive in a handheld portable device powered by a battery. The method involves measuring the battery voltage before and after a flash is initiated and calculating the equivalent series resistance (ESR) of the battery. The calculated ESR is then used to adjust the flash current. The process may be repeated to correct for errors in the flash current.

  • Patent number: 8081992
    Abstract: Embodiments of a system and method for displaying a geographic location associated with an incoming call being received on a mobile device are provided. The mobile device has a user interface that provides a call screen to the user for identifying a phone number associated with the incoming call, and for displaying data including the geographic location associated with the incoming call. The geographic location is resolved by identifying a geographic location associated with a contact entry in the address book of the mobile device, or by comparing the area code of the phone number of the incoming call in a list of area codes and associated geographic location to find a match corresponding to the area code of the incoming call.

  • Patent number: 7835640
    Abstract: Various embodiments are described herein for a method and related apparatus for safely operating a camera flash on a mobile device powered by a battery module. Upon determination that the camera flash needs to be activated the method comprises measuring several battery parameters including the voltage and temperature of the battery module. An equivalent series resistance (ESR) of the battery module is determined based on the battery temperature. The maximum flash current is then determined based on the battery voltage, and ESR along with potential current loads that may occur during operation of the camera flash, and a minimum battery voltage for safe operation of the mobile device where the battery voltage has been adjusted if needed. The device is then configured to draw a current from the battery module that is not greater than the maximum flash current.
